x = -96/(-6)

x = 16

Answer:

5/12

Step-by-step explanation:

We know that Santos flipped the coin a total of 300 times. Out of the 300 times, he flipped 125 heads. We need to find a simplified ratio equivalent to:

125/300

First, a common factor is 5, so we can divide both sides by 5 to get:

25/60

We can divide it by more to simplify it down, so we can try another 5 to get:

5/12

5/12 would be the simpliest form

So 125/300 is equal to 5/12

Other forms: 5:12, 0.42, %42

Answer:

x = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Step 1: Solve

We can divide 3 from both sides to get "x" by itself

[tex]3x=1\\\frac{3x}{3} =\frac{1}{3} \\x = \frac{1}{3}[/tex]

Therefore x = [tex]\frac{1}{3}[/tex]

Answer:

[tex]\large \boxed{x=\frac{1}{3} }[/tex]

Step-by-step explanation:

[tex]3x=1[/tex]

We need to solve for the x variable. It is best to isolate the variable on one side of the equation to find the value that makes the equation true.

Divide both sides of the equation by 3.

[tex]\displaystyle \frac{3x}{3} =\frac{1}{3}[/tex]

Simplify the equation.

[tex]\displaystyle x=\frac{1}{3}[/tex]

Answer:

121

Step-by-step explanation:

Given data as per the question

Standard deviation = [tex]\sigma[/tex] = 840

Margin of error = E = 150

Confidence level = c = 95%

For 95% confidence, z = 1.96

based on the above information, the minimum number of clients surveyed by the travel agent is

[tex]n = (\frac{z\times \sigma}{E})^2[/tex]

[tex]= (\frac{1.96\times 840}{150})^2[/tex]

= 120.47

= 121

hence, the 121 number of clients to be surveyed

Therefore we applied the above formula to determine the minimum number of clients

Answer:

81.86%

Step-by-step explanation:

We are given that the mean GPA of students in a course at UC Davis is 3.2 with a standard deviation of 0.3.

Assuming that the data follows normal distribution.

Let X = GPA of students in a course at UC Davis

So, X ~ Normal()

The z score probability distribution for normal distribution is given by;

                              Z  =   ~ N(0,1)

where,  = population mean GPA = 3.2

           = standard deviation = 0.3

Now, the probability that the students in the course have a GPA between 2.9 and 3.8 is given by = P(2.9 < X < 3.8)

       P(2.9 < X < 3.8) = P(X < 3.8) - P(X  2.9)

       P(X < 3.8) = P(  <  ) = P(Z < 2) = 0.97725

       P(X  2.9) = P(    ) = P(Z  -1) = 1 - P(Z < 1)

                                                        = 1 - 0.84134 = 0.15866

The above probability is calculated by looking at the value of x = 2 and x = 1 in the z table which has an area of 0.97725 and 0.84134 respectively.

Therefore, P(2.9 < X < 3.8) = 0.97725 - 0.15866 = 0.8186

Hence, 81.86% of students in the course have a GPA between 2.9 and 3.8.

Answer:

a

normal approximation not appropriate in this instance because  

    [tex]np = 3300 * 0.9998 = 3299.3 > 5[/tex]

and  

     [tex]nq = 3300 * 0.0002 = 0.66 < 5[/tex]

b

  The probability is  [tex]P(X = 3300) = 0.52[/tex]

c

 The probability is  [tex]P(X = 3287) = 0[/tex]

Step-by-step explanation:

From the question we are told that

   The  sample size is  [tex]n = 3300[/tex]

    The  chance of liking blueberry pie is  [tex]p = 0.9998[/tex]

    The  chance of not  liking blueberry pie is [tex]q = 0.0002[/tex]

For normal approximation is possible if  

       [tex]np > 5[/tex] , [tex]nq > 5[/tex]

Now let test

      [tex]np = 3300 * 0.9998 = 3299.3 > 5[/tex]

and  

     [tex]nq = 3300 * 0.0002 = 0.66 < 5[/tex]  

The  probability that all 3300 people will say they like blueberry pie is mathematically represented as

       [tex]P(X = 3300) = p^{3300}[/tex]

       [tex]P(X = 3300) = (0.9998)^{3300}[/tex]

        [tex]P(X = 3300) = 0.52[/tex]

The probability that 3297 of the people will say that they like blueberry pie is  mathematically represented as

         [tex]P(X = 3287) = \frac{(np)^{3297! } * e^{-np}}{3297}[/tex]

          [tex]P(X = 3287) = \frac{0}{\infty}[/tex]

          [tex]P(X = 3287) = 0[/tex]

Answer:

The expression is T = b+s

Step-by-step explanation:

If b represents the number of bikes and s represents the number of skateboards Donte is planning to repair to save up money for college, the total number of things he can repair in a day will be expressed as the sum of number of bikes and number of skateboards i.e b+s = T

Given that He can repair up to 2 bikes per day, the total and 4 skateboards per day this means that b = 2 and s = 4

Total number of thing's he can repair in a day given this amount T = 2 + 4 = 6 things

Answer:

12.25

Step-by-step explanation:

There are 36 outcomes in a throw of 2 dice throws here.

The amount we would be willing to pay is computed here as the expected product value for the 2 dice as we are risk neutral, therefore we would be using the expected value.

The expected values here are computed as:

X P(X = x) xP(X =x)

1 1 1

2 2 4

3 2 6

4 3 12

5 2 10

6 4 24

8 2 16

9 1 9

10 2 20

12 4 48

15 2 30

16 1 16

18 2 36

20 2 40

24 2 48

25 1 25

30 2 60

36 1 36

36 441

Using the above table, the expected amount here is computed as:

[tex]E(X) = \frac{441}{36} = 12.25 [/tex]

Therefore 49/4 is the required expected value here.

The expected value represents the amount you are willing to pay.

The amount you are willing to pay is #12.25

Let the dice be A and B.

So, we have:

[tex]A = \{1,2,3,4,5,6\}[/tex]

[tex]B = \{1,2,3,4,5,6\}[/tex]

The sample space of the product of the outcomes of the dice is:

[tex]S = \{1,2,3,4,5,6\\2,4,6,8,10,12\\3,6,9,12,15,18\\4,8,12,16,20,24\\5,10,15,20,25,30\\6,12,18,24,30,36\}[/tex]

The sample size is:

[tex]n(S) = 36[/tex]

The amount you are willing to pay is the expected value of the sample space.

This is calculated using:

[tex]Expected = \frac{\sum(S)}{n(S)}[/tex]

[tex]Expected = \frac{1+2+3+4+5+6+.......+36}{36}[/tex]

[tex]Expected = \frac{441}{36}[/tex]

[tex]Expected = 12.25[/tex]

Hence, the amount you are willing to pay is #12.25

Answer: Yes, this is a linear function between P and M.

Step-by-step explanation:

We can define a function as a relation between two or more variables, like y = f(x).

This function, maps the elements x (the input) into elements y (the output).

We have a rule for a function: Each input x can be mapped into only one output y.

In this case, we have:

P = 0.15*M + 20.

Let's prove that each value of M is related to only one value of P.

Suppose that, for a given M0, we have:

0.15*M0 + 20 = p1

and also for M0, we have:

0.15*M0 + 20 = p2

This means that p1 = p2, so we can not have different outputs for the same input.

This is a linear relation, so each value of M is related to only one value of P.

Then this is a function P(m) = 0.15*M + 20.

Answer:

35.71%

Step-by-step explanation:

So, let's determine the number of jobs the industry will have in 2030.

So, in 2020, the industry has 123,200 jobs.

Each year, the industry loses 4,400 jobs.

Thus, by 10 years in (2030), the industry would have lost (4,400)(10) or 44,000 jobs.

This means that in 2030, there will only be 123,200-79200 jobs left.

Now, percentage change is given by:

[tex]PC=\frac{New-Old}{Old}\cdot100\%[/tex]

The new value is 79200 and the old value is 123,200. Substitute them:

[tex]PC=\frac{(79200)-(123200)}{123200}\cdot100\%\\[/tex]

Use a calculator. Simplify:

[tex]PC=\frac{-44000}{123200}\cdot100\%\\ PC\approx-0.3571\cdot100\%\\PC\approx-35.71\%[/tex]

If the result is negative, then it's a decrease. Therefore, the percentage change from 2020 to 2030 is approximately 35.71%

Answer:

The answer is 35.71%

Step by step explanation

In 2020 the industry has 123,200 jobs.

Each year, the industry loses 4,400 jobs.

Thus, by 10 years in (2030), the industry would have lost (4,400)(10) or 44,000 jobs.

This means that in 2030, there will only be 123,200-79200 jobs left.

Now, percentage change is given by:

New−Old

⋅100%

The new value is 79200 and the old value is 123,200. Substitute

123200

(79200)−(123200)

⋅100%

Simplify:

PC≈−0.3571⋅100%

PC≈−35.71%

the percentage change from 2020 to 2030 is 35.71%

Answer:

He will have 12 small shirts and 18 large shirts.

Step-by-step explanation:

How I know this is because to get from 4 to 24 you have to multiply by 6, so I multiplied 6x2 and got 12, and I also multiplied 6x3 and got 18.

The manager plans to order 24 medium shirts. he will have 12 small shirts and 18 large shirts.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that a manager of a clothing store always orders 2 small shirts and 3 large shirts for every 4 medium shirts ordered.

The manager plans to order 24 medium shirts.

We need to get from 4 to 24.

So we have to multiply by 6,

so multiplied 6 x 2 = 12,

and multiplied 6 x 3 = 18.

Therefore, The manager plans to order 24 medium shirts. he will have 12 small shirts and 18 large shirts.

Answer:

The temperature at midnight is 100°F.

Step-by-step explanation:

We are given that early this morning the temperature was 54°F, around noon the temperature increase by 45°, at 5 PM a north wind made the temperature fall by 49°F but just before midnight the wind started to blow for from the south making the temperature in rise by 50°F.

Firstly, the early morning temperature was = 54°F

Now, it is stated that around noon the temperature increase by 45°, so the temperature around noon will be = 54°F + 45°F = 99°F

At 5 PM a north wind made the temperature fall by 49°F, this means there will be a decrease in the temperature level = 99°F - 49°F = 50°F

Finally, just before midnight; there is an increase in the temperature level of  50°F, so the temperature at midnight would be = 50°F + 50°F = 100°F

Hence, the temperature at midnight is 100°F.

Answer:

There is not enough evidence to support the mangers claim.

Step-by-step explanation:

We are given;

Sample Size; n = 1600

Sample proportion; p^ = 0.26

Population Proportion; p = 0.24

The hypotheses are;

Null Hypothesis: H0: p = 0.24

Alternative Hypothesis: Ha: p ≠ 0.24

The z-formula for this is;

z = (p^ - p)/√(p(1 - p)/n)

Plugging in the relevant values, we have;

z = (0.26 - 0.24)/√(0.24(1 - 0.24)/1600)

z = 0.02/0.01067707825

z = 1.87

From online p-value from z-score calculator, with 2 tail attached, we have;

p = 0.061484

This p-value is less than the significance level of 0.1. Thus, we will reject the null hypothesis and conclude that there is not enough evidence to support the managers claim.

Answer:

2,000 children attended and 1,250 adults attended.

The equations needed to solve these problems are:

[tex]x+y=3250\\2.00x+4.50y=9625[/tex]

Step-by-step explanation:

First, set up a system of equations.  Let "x" equal the number of children who attended the class and let "y" equal the number of adults who attended the class.

Our two equations to use to solve this problem are:

[tex]x+y=3250\\2.00x+4.50y=9625[/tex]

Then, I took the first equation and I isolated the x-variable:

[tex]x+y=3250\\x+y-y=3250-y\\x=3250-y[/tex]

Then, I substituted (3250-y) in for the x-variable in the second equation and I solved for "y":

[tex]2.00x+4.50y=9625\\2.00(3250-y)+4.50y=9625\\6500-2.00y+4.50y=9625\\6500+2.50y=9625\\6500-6500+2.50y=9625-6500\\2.5y=3125\\\frac{2.5y}{2.5}=\frac{3125}{2.5}\\ y=1250[/tex]

Next, I substituted the y-value that I got in for the y-variable in the first equation:

[tex]x+y=3250\\x+1250=3250\\x+1250-1250=3250-1250\\x=2000[/tex]

Finally, now that I have found both the x-value and the y-value, I will use the values to check  in both of my equations:

Equation 1:

[tex]x+y=3250\\2000+1250=3250\\3250=3250[/tex]

It works for Equation 1.

Equation 2:

[tex]2.00x+4.50y=9625\\2.00(2000)+4.50(1250)=9625\\4000+5625=9625\\9625=9625[/tex]

It works for Equation 2.

Therefore, the values work.

That means that 2000 children attended the class and 1250 adults attended the class.
