If 750 people were surveyed, how many people like grapes? Enter the number of people in the box.

Answers

Answer 1

Using the given percentages we can see that 150 people likes grapes.

How many people like grapes?

To find this, we need to take the product between the percentage of people that likes grapes (in decimal form) and the total number of people surveyed.

To get the decimal form of the percentage we just need to divide it by 100%, we will get:

20%/100% = 0.2

And there were 750 people surveyed, then the total number of people that likes grapes is:

N = 750*0.2 = 150.

Answers

Answer:

A $0.05n< $0.45

Step-by-step explanation:

It is given that she has "less than" rather than "less than or equal to" 45 cents. Therefore, your answer will contain the "less than" sign, which is signified as <.

Therefore, being the only answer with <, your answer will be A.

A nickel is $0.05, therefore:

$0.05 of n is less than $0.45, or $0.05n< $0.45

2. Two players A and B are competing at a trivia quiz game involving a series of questions. On any individual question, the probabilities that A and B give the correct answer areαandβrespectively, for all questions, with outcomes for different questions being independent. The game finishes when a player wins by answering a question correctly. Compute the probability that A wins if

a) A answers the first question,

b) B answers the first question. ​

Answers

a) The probability that A wins if A answers the first question is α / (α + β).

b) The probability that A wins if B answers the first question is βα+β.

a) If A answers the first question, then the game will be over only if A answers the first question correctly, which has a probability of α. If A answers incorrectly, then B gets to answer the next question, and we are in the same situation but with A's and B's roles reversed. Therefore, the probability that A wins in this case is given by:

P(A wins | A answers first) = α + (1 - α)β P(A wins | B answers first)

b) If B answers the first question, then we are in the same situation as in part a) but with A's and B's roles reversed. Therefore, the probability that A wins in this case is given by:

P(A wins | B answers first) = β P(A wins | A answers first) + (1 - β)β P(A wins | B answers first)

We can solve these equations for P(A wins | A answers first) and P(A wins | B answers first) using algebraic manipulation. For example, we can rearrange the equation in part a) to get:

P(A wins | A answers first) = α / (1 - (1 - α)β)

Similarly, we can rearrange the equation in part b) to get:

P(A wins | B answers first) = β / (1 - (1 - β)α)

Note that these probabilities depend on the values of α and β, which represent the abilities of A and B to answer questions correctly.

  (b) p = 50x +75y; 30 tons of loam and 90 tons of peat will maximize profit

Step-by-step explanation:

You want a graph of constraints and the solution to the problem of maximizing profit from sale of 60 tons of loam and 90 tons of peat at a profit of $50/t and $75/t, respectively, if at most 120 tons can be sold.

(a) Constraints

Let x and y represent tons of loam and peat, respectively. Then the constraints can be written as the inequalities ...

0 ≤ x ≤ 60 . . . . . can only sell as much as is available0 ≤ y ≤ 90 . . . . . can only sell as much as is availablex + y ≤ 120 . . . . . can sell a maximum of 120 tons

(b) Objective function

We want to maximize profit, so maximize ...

  p = 50x +75y

Graph

The attached graph shows the graphs of the inequalities. The restrictions on the variables confine the applicable graph to the first quadrant.

The black line shows the objective function. The value of the profit function is maximized when the line is as far from the origin as possible. The boundary point of the constraint solution space that maximizes profit is (x, y) = (30, 90).

Sale of 30 tons of loam and 90 tons of peat soil will maximize profit.

__

Additional comment

Since selling peat is the most profitable, profit will be maximized when we sell as much peat as possible. Sale of only 90 tons is possible, so profit will be maximized when we sell that many, then make up the rest of the 120 ton maximum by selling loam. We don't need a graph or a list of constraints to figure that out.

The daily temperatures for the winter months in Virginia are Normally distributed with a mean of 59 F and a

standard deviation of 10°F. A random sample of 10 temperatures is taken from the winter months and the mean

temperature is recorded. What is the standard deviation of the sampling distribution of the sample mean for all

possible random samples of size 10 from this population?

Answers

The  standard deviation of the sampling distribution of the sample mean for the given sample size is equal  to 3.1623°F.

For the normally distributed data,

Mean of the population distribution 'μ' = 59F

Population standard deviation 'σ' = 10°F

Sample size 'n' = 10

Formula for the standard deviation of the sampling distribution of the sample mean (also known as the standard error of the mean) is equal to ,

= σ / √(n)

Substitute the value to get the standard deviation of the sampling distribution of the sample mean we get,

= 10°F / √(10)

= 3.1623°F

Therefore, the standard deviation of the sampling distribution of the sample mean for all possible random samples of size 10 from this population is approximately 3.1623°F.

The standard deviation of a normal distribution of exam scores is 8. A score that is 12 points above the mean would have a z-score of 1.5, and a score that is 20 points below the mean would have a z-score of -2.5.

What is the z-score?

The z-score can be calculated by dividing the difference between a data value and the mean of the data set by the standard deviation of the data set.

The z-score of a score that is 12 points above the mean in a normal distribution of exam scores with a standard deviation of 8.

z = (x−μ)/σ = (x−μ)/σ = (12−0)/8 = 1.5

The z-score of a score that is 12 points above the mean in a normal distribution of exam scores with a standard deviation of 8 is 1.5.

The z-score of a score that is 20 points below the mean in a normal distribution of exam scores with a standard deviation of 8.

z = {x-μ}/{σ}  = {-20-0}/{8}  = −2.5

Problem: Power Output. In each case, find your average power in watts. Assume that riding a bike burns 100 Calories per mile. If you ride at a speed of 20 miles per hour, what is your average power output, in watts?

Answers

The average power output of a bike rider at a speed of 20 miles per hour is 556 W

Given, Riding a bike burns 100 Calories per mile. Speed of riding a bike is 20 miles per hour. Power is a measure of the rate at which work is done over time.

Therefore, the formula for average power is given by,

P = W/t

Where, P is power, W is work and t is time.

Now, We know that riding a bike burns 100 Calories per mile, but we have to find out the work done.

So, work done = 100 Calories × distance traveled= 100 × 1.609 × 1000 = 160900 J

Time taken = distance/speed= 1.609/20 = 0.08045 hours

Putting values in the formula of power, we get,

P = W/t= 160900/0.08045= 1999999.9 J/hour

Converting hour to seconds,1 hour = 3600 seconds1 J/s = 1 watt1 J/hour = 1 / 3600 watt

Therefore, power = 1999999.9 / 3600= 555.5556 watts (approx)

Therefore, the average power output of a bike rider at a speed of 20 miles per hour is 556 W (approx). Answer: 556

A professor grades students on a normal curve. For any grade x, based on the a course mean and standard deviation developed over years of testing, the following applies: D:--1.60 < x < -0.4σ How many A, B, C and D grades are given per 100 students?

Answers

The proportion of students with a z-score between -1.20 and -0.30 is about 0.304. So for every 100 students.

What is the z-score?

Z-score indicates how much a given value differs from the standard deviation. The Z-score, or standard score, is the number of standard deviations a given data point lies above or below the mean. Standard deviation is essentially a reflection of the amount of variability within a given data set.

Assuming that the grading follows a standard normal distribution (i.e., with a mean of 0 and a standard deviation of 1), we can use the z-score formula to find the proportions of students that fall within each grade range:

For an A grade: z-score > 1.65

For a B grade: 0.67 < z-score ≤ 1.65

For a C grade: -0.40 < z-score ≤ 0.67

For a D grade: -1.60 < z-score ≤ -0.40

To convert from the standard normal distribution to the distribution with the course mean and standard deviation, we can use the formula:

z-score = (x - mean) / standard deviation

We don't know the actual mean and standard deviation for the course, so we'll use the given range for the D grade (-1.60 < x < -0.4σ) to estimate the standard deviation. Since the D grade range is 1.2 standard deviations wide (from -1.60 to -0.4σ), we can solve for the standard deviation:

1.2σ = -1.60

σ = -1.60 / 1.2

σ = 1.33

(Note that we have a negative value for σ, which is not possible for a standard deviation. This is because we are using the estimated value of σ to convert from the standard normal distribution to the course distribution, which may not perfectly match the actual distribution of grades.)

Now we can use the z-score formula with the estimated mean and standard deviation to find the proportions of students in each grade range:

For an A grade: z-score > 1.65

z-score = (x - mean) / standard deviation

z-score = (1.65 - 0) / 1.33

z-score = 1.24

From standard normal distribution tables or a calculator, we can find that the proportion of students with a z-score greater than 1.24 is about 0.107. So for every 100 students, we can expect about:

A grades: 100 * 0.107 = 10.7 or approximately 11

For a B grade: 0.67 < z-score ≤ 1.65

z-score = (0.67 - 0) / 1.33

z-score = 0.50

From standard normal distribution tables or a calculator, we can find that the proportion of students with a z-score between 0.50 and 1.24 is about 0.205. So for every 100 students, we can expect about:

B grades: 100 * 0.205 = 20.5 or approximately 21

For a C grade: -0.40 < z-score ≤ 0.67

z-score = (-0.40 - 0) / 1.33

z-score = -0.30

From standard normal distribution tables or a calculator, we can find that the proportion of students with a z-score between -0.30 and 0.50 is about 0.307. So for every 100 students, we can expect about:

C grades: 100 * 0.307 = 30.7 or approximately 31

For a D grade: -1.60 < z-score ≤ -0.40

z-score = (-1.60 - 0) / 1.33

z-score = -1.20

Hence, From standard normal distribution tables or a calculator, we can find that the proportion of students with a z-score between -1.20 and -0.30 is about 0.304. So for every 100 students,

Part III: Short Answer Items (Worth 3 points) Instruction: Write the most simplified answer on the blank space provided for each of them. 11. If the price of an item is Birr 9,500 before VAT, then the total cost of the item including VAT​

Answers

According to the VAT rate, the total cost of the item including VAT is Birr 10,925 assuming a VAT rate of 15%.

What is VAT rate ?

VAT (Value Added Tax) rate is a percentage that is added to the price of goods or services. VAT is usually charged on top of the base price of a product or service, and the total price is calculated as (base price) + (base price x VAT rate). The VAT rate is typically set by the government and may be subject to change over time.

To find the total cost of the item including VAT, we need to know the VAT rate.

Let's assume the VAT rate is 15%. To calculate the VAT amount, we can multiply the price before VAT by the VAT rate:

VAT amount = 0.15 x 9,500 = Birr 1,425

The total cost of the item including VAT is the sum of the price before VAT and the VAT amount:

Total cost = 9,500 + 1,425 = Birr 10,925

Therefore, the total cost of the item including VAT is Birr 10,925 assuming a VAT rate of 15%.

Suppose Alice uses the RSA methods as follows. She starts with a message consisting of several letters, and assigns a = 1,b=2, -2=26. She then encrypts each letter separately. For example, if her message is cat, she calculates 3 = mod n 19 = 2 mod n and 209 = mod n. Then she sends the encrypted message {G}=1,2,3 to Bob.The solution to the given question is as follows:Eva knows that n = 8881 = 79 × 112, where p = 79 and q = 112 are primes.Using the extended Euclidean algorithm and the fact that 13*5081 = 1 (mod 8880), one can compute the inverse of e modulo 8880 as d ≡ 5081 ≡ -3805 (mod 8880).To compute the message, Alice encrypts each letter of the message separately using the encryption function y ≡ x13 (mod 8881).Eva receives {G}=1,2,3 from Alice, and hence she wants to decipher it by computing 13 ≡ y ≡ G13 (mod 8881), where y is the message.To compute y, we have 1^{13} ≡ 1 (mod 8881), 2^{13} ≡ 8192 ≡ - 6889 + 2 (mod 8881) since 8192 = 2 × 4096 and 4096 = 8881 - 4785, hence, 2^{13} ≡ - 4785 × 2 + 2 (mod 8881), i.e., 2^{13} ≡ 2311 (mod 8881), and 3^{13} ≡ 3 × 3^{12} ≡ 3 × (3^{4})^{3} ≡ 3 × 6561^{3} ≡ 3 × 4299 ≡ 12897 ≡ 2557 (mod 8881).Therefore, the decrypted message is {y} = (2311, 2557, 2015) and hence the original message is CAT.Hence, the solution is {y} = (2311, 2557, 2015) and hence the original message is CAT.

Reduce each expression to a polynomial

((y-b)^(2))/(y-b+1)+(y-b)/(y-b+1)

Answers

The given expression ((y-b)²/(y-b+1)+(y-b)/(y-b+1) after being reduced to a polynomial, can be represented as y-b.

In order to reduce the given equation to a polynomial, we are required to simplify and combine like terms. First, we can simplify the expression in the numerator by expanding the square:

((y-b)²/(y-b+1) = (y-b)(y-b)/(y-b+1) = (y-b)²/(y-b+1)

Now, we can combine the two terms in the equation by finding a common denominator:

(y-b)²/(y-b+1) + (y-b)/(y-b+1) = [(y-b)² + (y-b)]/(y-b+1)

Next, we can combine the terms in the numerator by factoring out (y-b):

[(y-b)² + (y-b)]/(y-b+1) = (y-b)(y-b+1)/(y-b+1)

Finally, we can cancel out the common factor of (y-b+1) in the numerator and denominator to get the polynomial:

(y-b)(y-b+1)/(y-b+1) = y-b

Therefore, the equation ((y-b)²)/(y-b+1)+(y-b)/(y-b+1)  after being simplified, is equivalent to the polynomial y-b.

The given volume of the box is 62500 cm³. We wish to find the dimensions of the box that minimize the amount of material used.

To obtain the formula for the surface area of the box in terms of only x, the length of one side of the square base, we use the formula for the volume of a box:V = lwh ... (1) ... where V is the volume, l is the length, w is the width, and h is the height of the box. Here, the base of the box is a square with side length x.

Hence, the area of the square base = x². Therefore, we have:l = w = x ... (2) ... And, h = V/lw = V/x² ... (3) ... We can substitute (2) and (3) in (1) to get the formula for V in terms of x as follows:V = x² V/x² A(x) = A(x) = x² + 4xhA(x) = x² + 4x(V/x²) = x² + 4V/x

Now, to find the derivative A'(x) of A(x), we differentiate A(x) with respect to x:A'(x) = 2x - 4V/x²  A'(x) = 0 when x =  (2V)1/3. Therefore, the dimension of the box that minimizes the amount of material used is x =  (2V)1/3. A(x) = x² + 4V/x, A'(x) = 2x - 4V/x², x =  (2V)1/3

The οptiοn in the questiοn that is equivalent tο 3/8 is 2/5.

Equivalent- Meaning in Mathematics

The term "equivalent" in math refers tο twο meanings, numbers, οr quantities that are the same. The equivalence οf twο such quantities shall be denοted by a bar οver an equivalent symbοl οr Equivalent Sign. It alsο means a lοgical equivalence between twο values οr a set οf quantities. Equivalence is similar but mοre universal than equality. If twο sets οf equatiοns have the same sοlutiοns, we might cοnsider them similar, but they are nοt identical.

Hοw tο calculate the equivalent οf 3/8?  

We can simplify 3/8 and 2/5 sο that they have a cοmmοn denοminatοr:

3/8 = 3*(5/5)/(85/5) = 15/40

2/5 = 2(8/8)/(5*8/8) = 16/40

Since 15/40 and 16/40 have the same denοminatοr, we can cοmpare their numeratοrs tο see which is larger:

15/40 < 16/40

Since 16/40 is larger, we can cοnclude that 2/5 is greater than 3/8.

The sum of the base and the height of a triangle is 22 cm. Find the dimensions for which the area is a maximum. The triangle with maximum area has a height of_____cm and a base of cm_____.

Answers

The dimensions of the triangle with maximum area are a base of 11 cm and a height of 11 cm.

We are given that the sum of the base and height of a triangle is 22 cm. Let's call the base of the triangle "b" and the height "h". Then we have the equation:

b + h = 22

We want to find the dimensions of the triangle that will give us the maximum area.

The formula for the area of a triangle is A = (1/2)bh.

We can use the equation b + h = 22 to solve for one of the variables in terms of the other.

we can solve for h:

h = 22 - b

Substituting this into the formula for the area, we get:

A = (1/2)b(22 - b)

The equation 0 = 11b - (1/2)b² can be rearranged to:

(1/2)b² - 11b = 0

We can then use the quadratic formula to solve for "b"

b = 11 ± 11

So the value of b that gives us the maximum area is b = 11 cm. Substituting this back into the equation h = 22 - b, we get:

h = 22 - 11 = 11 cm

Triangle has a base of 11 cm and a height of 11 cm.

Answers

The five fold health hazards prevalent in Nepal are respiratory diseases due to high altitude, Germ cell mutagenicity, Carcinogenicity, Reproductive toxicity and sanitation related issues which causes diarrhea, cholera like diseases.

Nepal is a small country in hilly region of Himalayas between China and India. It has not developed much in terms of health care facilities and advanced treatment methods due to which people migrate to India for treatments in several extreme diseases. The low life expectancy is because of poor employment which causes financial insecurity and hence people are either malnourished, or die of lack of proper treatment.

The Nepal Health Sector Program – Implementation Plan (NHSP-IP) has been developed in order to meet the Health Sector Strategy which has its agenda to improvise the needs of the people in near future.

Harry Potter purchases a new broom called The Firebolt that sells for $3,200, including tax. It requires a $201 down payment. The remainder, plus a finance charge, is paid back monthly over the next two and a half years. The monthly payment is $114. What is the finance charge? (Do not include the $ symbol or .00 in your answer)

Answers

Answer: 210

Explanation: The total amount to be paid back is the selling price of the broom plus the finance charge, which is:

$3,200 + finance charge

The down payment of $201 is subtracted from this amount, leaving the balance to be paid back over 30 monthly payments:

$3,200 + finance charge - $201 = $2,999 + finance charge

Each monthly payment is $114, so the total amount paid over 30 months is:

30 x $114 = $3,420

This includes both the amount borrowed ($2,999 + finance charge) and the finance charge, so we can set up the equation:

$3,420 = $2,999 + finance charge + finance charge

Simplifying this equation, we get:

$421 = 2 x finance charge

finance charge = $210.50

Therefore, the finance charge is $210.50

Answers

Probability that X = 5:Since, Joe selects only 4 bags of lettuce. X can't be 5.P(X=5) = 0Hence, the probability that X = 0 is 0.3164 and the probability that X = 5 is 0.

The given problem can be solved using the concept of binomial distribution.

In the given question, there are 48 bags of lettuce out of which 12 bags are contaminated with listeria.

Joe selects 4 bags of lettuce. X is the random variable which represents the number of contaminated bags of lettuce selected by Joe. X can take values from 0 to 4. (as Joe selects only 4 bags).

Part A)Number of ways to select 4 bags of lettuce out of 48:This can be solved using the concept of combinations. The formula to calculate the number of combinations is[tex]:nCr = n! / r!(n-r)![/tex]Here, n = 48 and r = 4.

Number of ways = 48C4 = 194,580

Part B)Probability that X = 0:This can be calculated using the formula for the binomial distribution :

[tex]P(X = r) = nCr * p^r * q^(n-r)[/tex]

Here, p = probability of selecting contaminated bag = 12/48 = 0.25q = probability of selecting non-contaminated bag = 1-0.25 = 0.75Also, n = 4 and r = [tex]0P(X=0) = 4C0 * 0.25^0 * 0.75^4= 0.3164[/tex]

question if all other factors are held constant, which of the following results in an increase in the probability of a type ii error? responses the true parameter is farther from the value of the null hypothesis. the true parameter is farther from the value of the null hypothesis. the sample size is increased. the sample size is increased. the significance level is decreased. the significance level is decreased. the standard error is decreased. the standard error is decreased. the probability of a type ii error cannot be increased, only decreased.

Answers

If all other factors are held constant, decreasing the significance level results in an increase in the probability of a type II error. This is true. we can say that the probability of making a type II error increases when the significance level is lowered.

What is a type II error? In hypothesis testing, a type II error occurs when a false null hypothesis is not rejected. When there is a real effect and the null hypothesis is false, this happens. It's a mistake that occurs when a researcher fails to reject a false null hypothesis.

A false negative is another term for a type II error. The power of the test, the size of the sample, the confidence level, and the effect size are all factors that influence the probability of making a type II error. Only if we decrease the significance level can the probability of a type II error be increased.

What is the significance level? The significance level is also known as alpha. It is the probability of rejecting a null hypothesis when it is true. It is represented by α. It is usually set at 0.05 or 0.01 in most studies. When the significance level is lowered, the probability of making a type I error decreases, but the probability of making a type II error increases. Therefore, we can say that the probability of making a type II error increases when the significance level is lowered.

(hob-evzw-zjw) come

Answer:

B is your answer.
10.80$ which you just round to 10. 10 is your answer.

Step-by-step explanation:

For simple interest, the formula is:

Simple Interest = Principal × Rate × Time

For compound interest, the formula is:

Compound Interest = Principal × (1 + Rate)^Time - Principal

Let's calculate the values:

Principal = $3,000

Rate = 6% or 0.06

Time = 2 years

Simple Interest = $3,000 × 0.06 × 2 = $360

To calculate compound interest, we need to use the formula:

Compound Interest = $3,000 × (1 + 0.06)^2 - $3,000

= $3,000 × (1.06)^2 - $3,000

= $3,000 × 1.1236 - $3,000

= $3,370.80 - $3,000

= $370.80

The difference between simple and compound interest is:

$370.80 - $360 = $10.80

Should we write reciprocal for 5/6 in this question 5 × 5/6

Answers

If the question is simply asking for the product of 5 and 5/6, then writing the reciprocal is not necessary. To multiply fractions, we can simply multiply the numerators and the denominators separately. In this case, we would get:

5 x 5/6 = (5 x 5)/(1 x 6) = 25/6

However, if the question specifically asks for the result to be expressed as a mixed number or a whole number, then we would need to simplify the fraction by converting it to a mixed number or a whole number. In some cases, it may be helpful to write the reciprocal in order to simplify the fraction more easily.

For example, if the question asks us to express 5 x 5/6 as a mixed number or a whole number, we could first write the reciprocal of 5/6 as 6/5, and then multiply it with 5 to get:

5 x 5/6 = 5 x 6/5 = 30/5

We can simplify this fraction by dividing both the numerator and the denominator by 5:

30/5 = 6

Therefore, if the context or the desired result requires the expression 5 x 5/6 to be simplified further, it may be helpful to write the reciprocal of 5/6 to make the simplification process easier. However, in general, it is not necessary to write the reciprocal to multiply fractions.
