In total, 2 baseballs and 3 footballs cost $67. a football is $4 more than 3 times the cost of a baseball. find the cost of a baseball

Answers

Answer 1

The cost of the Baseball is $5.

Lets take football cost as "x"

And taking baseball cost as "y"

According to given conditions,

2y + 3x = 67

x= 3y + 4

Lets put the values of x in equation (1):

2y + 3 (3y+4) = 67

=> 2y + 9y + 12 = 67

=> 11y = 55

y = 5

x = 3(5) + 4

x = 19

Hence the cost of the Baseball is $5.

Johnny has $100 dollars in the bank and he plans to deposit $15 per week! write an equation to find out how much money johnny has saved! what’s the independent and dependent variable?

Answers

The equation to find out how much money Johnny has saved is: Total money saved = 100 + 15W. Independent variable: Number of weeks (W) and Dependent variable: Total money saved.

We are given the following information:

Johnny has $100 in the bank initially.

He plans to deposit $15 per week.

To find out how much money Johnny has saved over time, we can use an equation that calculates the total money saved based on the number of weeks.

Let's define the variables: W represents the number of weeks.

Total money saved represents the amount of money Johnny has saved over time. The equation to calculate the total money saved is:

Total money saved = $100 + ($15 * Number of weeks)

In this equation, the $100 represents the initial amount Johnny had in the bank. The ($15 * Number of weeks) represents the total amount he has deposited over the number of weeks.

The independent variable is the "Number of weeks" because it can vary, and we can calculate the total money saved for different time periods by plugging in different values for this variable.

The dependent variable is the "Total money saved" because it depends on the number of weeks. The value of this variable changes based on the number of weeks Johnny has been saving.

By plugging in different values for the number of weeks (W), we can calculate the corresponding total money saved.

For example, if Johnny has been saving for 10 weeks, we can substitute W = 10 into the equation to find the total money saved over that time period.

Karim buys 200 tiles.
The tiles are sold in boxes.
There are 25 tiles in each box.
Each box of tiles costs £9. 75
Work out the total cost of the boxes of tiles Karim buys. ​

Answers

the total cost of the boxes of tiles Karim buys is £78.

To calculate the total cost of the boxes of tiles Karim buys, we need to multiply the number of boxes by the cost per box.

Given that there are 25 tiles in each box and Karim buys 200 tiles, we can determine the number of boxes as follows:

Number of boxes = Total number of tiles / Tiles per box

Number of boxes = 200 tiles / 25 tiles per box

Number of boxes = 8 boxes

Next, we multiply the number of boxes by the cost per box to find the total cost:

Total cost = Number of boxes * Cost per box

Total cost = 8 boxes * £9.75 per box

Total cost = £78

Answers

The statement is true because if the cross product of two vectors ~u and ~v in three-dimensional space is equal to the zero vector ~0, then it implies that either ~u or ~v is equal to the zero vector ~0.

The cross product ~u × ~v produces a vector that is perpendicular (orthogonal) to both ~u and ~v. If the resulting cross product is the zero vector ~0, it means that ~u and ~v are either parallel or collinear.

If ~u and ~v are parallel or collinear, it implies that they are scalar multiples of each other. In this case, one of the vectors can be expressed as a scaled version of the other. Consequently, either ~u or ~v can be the zero vector ~0.

Calculate S3, S, and Ss and then find the sum for the telescoping series 3C0 n + 1 n+2 where Sk is the partial sum using the first k values of n. S31/6 S4

Answers

The sum for the telescoping series is given by the limit of Sn as n approaches infinity:

S = lim(n→∞) Sn = lim(n→∞) 2 + 5/2 - 1/(n+1) = 9/2.

First, let's find Sn:

Sn = 3C0/(n+1)(n+2) + 3C1/(n)(n+1) + ... + 3Cn/(1)(2)

Notice that each term has a denominator in the form (k)(k+1), which suggests we can use partial fractions to simplify:

3Ck/(k)(k+1) = A/(k) + B/(k+1)

Multiplying both sides by (k)(k+1), we get:

3Ck = A(k+1) + B(k)

Setting k=0, we get:

3C0 = A(1) + B(0)

A = 3

Setting k=1, we get:

3C1 = A(2) + B(1)

B = -1

Therefore,

3Ck/(k)(k+1) = 3/k - 1/(k+1)

So, we can write the sum as:

Sn = 3/1 - 1/2 + 3/2 - 1/3 + ... + 3/n - 1/(n+1)

Simplifying,

Sn = 2 + 5/2 - 1/(n+1)

Now, we can find the different partial sums:

S1 = 2 + 5/2 - 1/2 = 4

S2 = 2 + 5/2 - 1/2 + 3/6 = 17/6

S3 = 2 + 5/2 - 1/2 + 3/6 - 1/12 = 7/4

S4 = 2 + 5/2 - 1/2 + 3/6 - 1/12 + 3/20 = 47/20

Finally, the sum for the telescoping series is given by the limit of Sn as n approaches infinity:

S = lim(n→∞) Sn = lim(n→∞) 2 + 5/2 - 1/(n+1) = 9/2.

a reserve requirement of 20 percent means a bank must have at least $3,000 of reserves if its checkable deposits are

Answers

If a bank has checkable deposits of 15,000, it would be required to hold 3,000 in reserves, based on a reserve requirement of 20%.

To calculate the amount of checkable deposits that would require a bank to hold 3,000 in reserves, we need to use the formula:

Required reserves = Reserve requirement ratio x Checkable deposits

If the reserve requirement is 20%, then the reserve requirement ratio is 0.20. Let's assume that the bank has checkable deposits of X dollars. Then we can set up the following equation:

0.20 X = 3,000

Solving for X, we get:

X = 3,000 ÷ 0.20

X = 15,000

Therefore, if a bank has checkable deposits of 15,000, it would be required to hold 3,000 in reserves, based on a reserve requirement of 20%.

If a bank has checkable deposits of $15,000 and a reserve requirement of 20 percent, it must have at least $3,000 of reserves on hand.

This reserve requirement is a regulation set by the Federal Reserve that requires banks to hold a certain percentage of their checkable deposits in reserves, either as cash in their vault or as deposits at the Federal Reserve. This requirement ensures that banks have enough funds on hand to cover withdrawals by customers and maintain financial stability. If a bank falls below the reserve requirement, it may be subject to penalties and restrictions on its ability to lend and operate.
A reserve requirement of 20 percent means that a bank must keep 20% of its checkable deposits as reserves. If a bank must have at least $3,000 of reserves, you can find the total checkable deposits by using the following steps:

1. Write down the equation: Reserves = Reserve Requirement × Checkable Deposits
2. Plug in the given values: $3,000 = 0.20 × Checkable Deposits
3. Divide both sides by 0.20 to find the Checkable Deposits: Checkable Deposits = $3,000 ÷ 0.20

Checkable Deposits = $15,000

Therefore, if a bank has a reserve requirement of 20 percent and must have at least $3,000 of reserves, its checkable deposits must be $15,000.

64% of U. S. Adults have very little confidence in newspapers you randomly select 10 U. S. Adults. Find the probability that the number of U. S. Adults who have very little confidence in news papers is (a) exactly five , (b) at least six, and (c) less than four

Answers

To solve this problem, we can use the binomial probability formula. The binomial distribution is applicable here because we have a fixed number of trials (selecting 10 U.S. adults) and each trial has two possible outcomes (having very little confidence or not having very little confidence in newspapers).

The formula for the probability of obtaining exactly 'k' successes in 'n' trials, where the probability of success is 'p', is:

[tex]P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)[/tex]

where C(n, k) represents the number of combinations of 'n' items taken 'k' at a time.

(a) To find the probability of exactly five U.S. adults having very little confidence in newspapers, we substitute the values into the formula:

[tex]P(X = 5) = C(10, 5) * (0.64)^5 * (1 - 0.64)^(10 - 5)[/tex]

Calculating this expression will give us the probability.

(b) To find the probability of at least six U.S. adults having very little confidence in newspapers, we need to calculate the sum of probabilities for six, seven, eight, nine, and ten successes:

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)

(c) To find the probability of less than four U.S. adults having very little confidence in newspapers, we need to calculate the sum of probabilities for zero, one, two, and three successes:

P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

Using the binomial probability formula and the appropriate combinations, we can calculate these probabilities.

Verify that (0, 0) and (10/3,0) are critical points of the following function: f(x, y) = 3x ^ 2 * y + 2x * y ^ 2 - 10xy - 8y ^ 2
Classify these given critical points into relative maximum, relative minimum or saddle
points.

Answers

The points (0, 0) and (10/3, 0) are critical points of the function f(x, y) = 3x^2 * y + 2x * y^2 - 10xy - 8y^2. The point (0, 0) is a saddle point, while the point (10/3, 0) is a relative minimum.

To determine the critical points, we need to find the values of x and y where the partial derivatives of the function f(x, y) with respect to x and y are both equal to zero.

Taking the partial derivative with respect to x, we have:

∂f/∂x = 6xy + 2y^2 - 10y

Taking the partial derivative with respect to y, we have:

∂f/∂y = 3x^2 + 4xy - 10x - 16y

Setting both partial derivatives equal to zero and solving, we find two critical points: (0, 0) and (10/3, 0).

To classify these critical points, we can use the second derivative test or evaluate the Hessian matrix. However, in this case, evaluating the Hessian matrix is not necessary. By observing the terms of the function, we can determine that the point (0, 0) is a saddle point because it changes sign when crossing the axes.

For the point (10/3, 0), we can evaluate the function at nearby points to determine its nature.

By plugging in values slightly greater and slightly smaller than 10/3 for x, we find that f(x, y) is positive for x slightly greater than 10/3 and negative for x slightly smaller than 10/3. Therefore, (10/3, 0) is a relative minimum.

B. It drops by approximately 20%. C. It drops by approximately 30%. OD. It drops by approximately 10%.

Answers

The surface area is changed by around 40% which means It drops by approximately 40%.

Option A is the correct answer.

We have,

To find the percentage change in surface area, we need to calculate the new surface area after the weight drop and then find the percentage difference.

Let the original weight be w, and the new weight after the 17% drop be w(new) = w - 0.17w = 0.83w.

The original surface area.

S(h, w) = √(hw) / 60.

The new surface area.

S(h, w_new) = √(h x 0.83w) / 60.

To find the percentage change, we calculate the difference between the two surface areas and divide it by the original surface area, then multiply by 100:

Percentage Change

= [(S(h, w) - S(h, w(new))) / S(h, w)] x 100

Now let's plug in the formula for surface area:

Percentage Change

= [((√(hw) / 60) - (√(h * 0.83w) / 60)) / (√(hw) / 60)] * 100

= [(√(hw) - √(h * 0.83w)) / √(hw)] * 100

= [0.398w / √(hw)] * 100

MRS FALKENER HAS WRITTEN A COMPANY REPORT EVERY 3 MONTHS FOR THE LAST 6 YEARS. IF 2\3 OF THE REPORTS SHOWS HIS COMPONY EARNS MORE MONEY THEN SPENDS, HOW MANY REPORTS SHOW HIS COMPANY SPENDING MORE MONEY THAN IT EARNS

Answers

Mrs. Falkener has written a company report every 3 months for the last 6 years, resulting in a total of 24 reports. Among these reports, 2/3 of them show the company earning more money than it spends. Therefore, 1/3 of the reports, or 8 reports, show the company spending more money than it earns.

In 6 years, there are 12 quarters since there are 4 quarters in a year. Mrs. Falkener has written a company report every 3 months, which means there are 12 * 3 = 36 periods in total. However, since each report covers a 3-month period, the total number of reports is 36 / 3 = 12.

Given that 2/3 of the reports show the company earning more money than it spends, we can calculate the number of reports showing the company spending more money than it earns. Since 2/3 of the reports represent the earnings being greater, the remaining 1/3 represents the expenses being greater. Therefore, 1/3 of 12 reports is 12 * (1/3) = 4 reports.

In conclusion, among the 24 company reports written by Mrs. Falkener in the last 6 years, 2/3 of them, or 16 reports, show the company earning more money than it spends. The remaining 1/3, or 8 reports, show the company spending more money than it earns.

Find the area of the rectangle ABCD with vertices A(-4, 4), B(1, 4), C(-4, 1) and D(1,1).

Answers

The area of the rectangle ABCD is approximately 29.15 square units.

To find the area of the rectangle ABCD, we can use the formula for the area of a rectangle, which is given by the product of its length and width.

Let's first find the length and width of the rectangle using the coordinates of its vertices.

Length AB = distance between points A and B

= √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(1 - (-4))² + (4 - 4)²]

= √[5² + 0²]

= √25

= 5

Width BC = distance between points B and C

= √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(-4 - 1)² + (1 - 4)²]

= √[(-5)² + (-3)²]

= √[25 + 9]

= √34

Now that we have the length and width, we can calculate the area of the rectangle.

Area = Length × Width

= 5 × √34

≈ 5 × 5.83

≈ 29.15 square units

Therefore, the area of the rectangle ABCD is approximately 29.15 square units.

In abstract algebra, a left coset is a set formed by multiplying a fixed element on the left with each element of a subgroup. In this case, we have the subgroup Ka4l within the group Kal. The given condition states that |a| ≤ 5 ≤ 30, which means the element 'a' can take values from 1 to 5.

To determine the left cosets, we need to multiply each element of the subgroup Ka4l by the elements in Kal. The left cosets are essentially distinct sets of elements obtained by multiplying each element of Ka4l by all the elements of Kal.

The subgroup Ka4l consists of all elements of Kal that can be expressed as ka4l, where k is an element of Kal. Multiplying each element of Ka4l by elements of Kal, we obtain the following left cosets:

1. {ka4l : k ∈ Kal}

2. {2a4l : k ∈ Kal}

3. {3a4l : k ∈ Kal}

4. {4a4l : k ∈ Kal}

5. {5a4l : k ∈ Kal}

6. {6a4l : k ∈ Kal}

These are the six left cosets of Ka4l in Kal.

Leo bought 3. 5lbs of strawberries that cost $4. 20. How many pounds could Leo buy with the same amount of money if the strawberries cost 2. 80 per pound

Answers

Leo could buy 1.5 pounds of strawberries if they cost $2.80 per pound.

How many pounds could Leo buy with the same amount of money

From the question, we have the following parameters that can be used in our computation:

3. 5lbs of strawberries that cost $4.20.

This means that

Cost = $4.20

Pounds = 3.5

For a unit rate of 2.8 we have

Pounds = 4.20/2.8

Evaluate

Pounds = 1.5

Hence, Leo could buy 1.5 pounds of strawberries if they cost $2.80 per pound.

Suppose you will perform a test to determine whether there is sufficient evidence to support a claim of a linear correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance level alpha n = 11, a = 0.01

Answers

Thus, For n = 11 and alpha = 0.01, the critical values of r are approximately -0.869 and 0.869. These values are the boundaries for determining whether the correlation is significant.

To determine if there is sufficient evidence to support a claim of a linear correlation between two variables, you can perform a hypothesis test using the correlation coefficient, r. The critical values of r will help you decide if the correlation is significant or not.

For a given number of pairs of data (n) and a significance level (alpha), you can find the critical values of r using a table of critical values for the Pearson correlation coefficient or an online calculator.

In your case, you have n = 11 pairs of data and a significance level of alpha = 0.01. Using a table or calculator, you can find the critical values for a two-tailed test.

For n = 11 and alpha = 0.01, the critical values of r are approximately -0.869 and 0.869. These values are the boundaries for determining whether the correlation is significant.

If the calculated value of r falls between these critical values (-0.869 and 0.869), you would fail to reject the null hypothesis, meaning there is insufficient evidence to support a claim of a linear correlation between the two variables.

However, if the calculated value of r is less than -0.869 or greater than 0.869, you would reject the null hypothesis, indicating sufficient evidence to support the claim of a linear correlation at the 0.01 significance level.

In ΔMNO, the measure of ∠O=90°, the measure of ∠M=13°, and OM = 9. 6 feet. Find the length of MN

Answers

In a right triangle, the right angle is marked as 90°. Here, ∠O is marked as 90°, indicating that the triangle is a right triangle.  

Moreover, the length of OM is given as 9.6 feet. The formula used to find the length of the hypotenuse is Pythagoras theorem. The formula is given as c² = a² + b². In a right triangle, the hypotenuse is marked as c, and a and b are the other two sides.

Let's use Pythagoras theorem to find the length of the hypotenuse, MN. MN is the hypotenuse.c² = a² + b²c² = 9.6² + 13²c² = 92.16 + 169c² = 261.16The square root of 261.16 is 16.16. Therefore, the length of MN is 16.16 feet. This is the required solution. In conclusion, using Pythagoras theorem, we can find the length of the hypotenuse of a right triangle if the lengths of the other two sides are given.

What is the radius of convergence of a power series function?

Answers

The radius of convergence of a power series function is a positive real number R that determines the interval of values for which the power series converges.

It represents the distance from the center of the power series expansion, within which the series converges. The radius of convergence is determined by the properties of the coefficients in the power series. Specifically, it is defined as the reciprocal of the limit superior of the absolute values of the coefficients. Mathematically, if we have a power series function of the form:

f(x) = ∑(n=0 to ∞) aₙ(x - c)ⁿ

where aₙ represents the coefficients and c is the center of the series, then the radius of convergence R is given by:

R = 1 / lim sup |aₙ|^(1/n)

The power series converges for all values of x within the interval (c - R, c + R). If |x - c| > R, the series diverges.

It's important to note that the radius of convergence can be zero, indicating that the power series only converges at the center point (x = c), or it can be infinite, indicating that the series converges for all values of x.

How many different 5-letter symbols can be formed from the word YOURSELF if the symbol must begin with a consonant and ends with vowel?

Answers

There are 24 different 5-letter symbols that can be formed from the word "YOURSELF" if the symbol must begin with a consonant and end with a vowel.

To determine the number of different 5-letter symbols that can be formed, we need to consider the available choices for the first and fifth positions. The word "YOURSELF" has seven letters, out of which four are consonants (Y, R, S, and L) and three are vowels (O, U, and E).
Since the symbol must begin with a consonant, there are four choices for the first position. Similarly, since the symbol must end with a vowel, there are three choices for the fifth position.
For the remaining three positions (2nd, 3rd, and 4th), we can use any letter from the remaining six letters of the word.
Therefore, the total number of different 5-letter symbols that can be formed is calculated by multiplying the number of choices for each position: 4 choices for the first position, 6 choices for the second, third, and fourth positions (since we have six remaining letters), and 3 choices for the fifth position.
Thus, the total number of different 5-letter symbols is 4 * 6 * 6 * 6 * 3 = 24 * 36 = 864.

a type of diagram that is used to graphically show the relationship between two numerical variables.

Answers

The type of diagram used to graphically show the relationship between two numerical variables is called a scatter plot.

A scatter plot is a visual representation of data points plotted on a graph, with one variable represented on the x-axis and the other variable represented on the y-axis.

Each data point on the plot corresponds to a pair of values from the two variables being analyzed. The position of each point on the graph indicates the values of both variables, allowing us to examine the relationship between them.

The main purpose of a scatter plot is to visualize the correlation or relationship between the two variables. The pattern formed by the data points on the plot can indicate the direction, strength, and nature of the relationship.

For example, if the points on the scatter plot tend to form a linear pattern, it suggests a linear relationship between the variables. On the other hand, if the points are scattered randomly with no clear pattern, it indicates a weak or no relationship between the variables.

Scatter plots are commonly used in various fields, including statistics, data analysis, and scientific research. They provide a visual way to explore and interpret relationships between variables, identify outliers, detect trends, and assess the strength and direction of associations.

If John mows 11. 5 meters of lawn from east to west in 7. 1 seconds, what is the velocity of the lawnmower?

Answers

The velocity is  1.62 meters per second to the west.

What is the velocity of the lawnmower?

We know that John mows 11.5 meters lan from east to west in 7.1 seconds.

Then we know that.

distance = 11.5 meters

time = 7.1 seconds.

To get the velocity, we just need to take the quotient between the distance and the time (and we need to clarifiy the direction), so we will get:

Velocity = distance/time

velocity = 11.5 meters/7.1 seconds

velocity = 1.62 meters per second to the west.

That is the velocity of the lawnmower.
