Answer:

C. The amount of gas left in Steve's car at his next visit to the gas

station is a function of the distance he drove.

Step-by-step explanation:

From the question, the car starts with a full tank of gas and the more the distance covered, the less gas will be left in the car at the next visit to the gas station.

The variables to take note are the distance travelled and the amount of gas left in the car at next visit to the gas station.

This means the farther he drives, the less gas will be left in the car because longer distances travelled consumes more gas in the car thus less gas will be left when the next visit to the gas station occurs.

Answer:  

The top of the ladder is 12.69 feet away from the ground

Step-by-step explanation:

Length of the ladder is given to be 15 foot

Also, The base of the ladder is 8 feet away from the wall.

Now, The height of the ladder will be perpendicular to the surface of the ground

So, It will form a right angled triangle

Now, The base of the triangle will be 8 feet

Hypotenuse of the triangle will be 15 feet

And we need to find the perpendicular height of the triangle

By using Pythagoras theorem, We have

Hypotenuse² = Base² + Perpendicular²

⇒ 15² = 8² + Perpendicular²

⇒ Perpendicular = 12.69 feet

Therefore, The top of the ladder is 12.69 feet away from the ground

Or 12.70 from rounding to your nearest tenths

a. To determine the industry average salary, we can use the information that the industry average salary is 96% of Firm B's average salary. Firm B's average salary is $58,000. Therefore, we can calculate the industry average salary as follows:

Industry Average Salary = 96% of Firm B's Average Salary

= 0.96 * $58,000

= $55,680

b. Firm A's average salary is stated as 93% of the industry average salary. To calculate Firm A's average salary, we can multiply the industry average salary by 93%:

Firm A's Average Salary = 93% of Industry Average Salary

= 0.93 * $55,680

= $51,718.40

c. To express Firm B's average salary as a percentage of Firm A's average salary, we can divide Firm B's average salary by Firm A's average salary and multiply by 100:

By applying probability concept, it can be concluded that the experimental probability of rolling each is P(1) = 1/6, P(2) = 1/7,  P(3) = 1/3,  P(4) = 2/21,  P(5) = 1/7, and P(6) = 5/42.

Probability is a value used to measure the degree of occurrence of a random event.

P(E) = n(E)/n(S)

n(E) = number of desired events

n(S) = total number of events

We have the following information about a die rolling 42 times:

One    Two    Three   Four     Five     Six

 7          6          14         4          6        5

The theoretical probability of rolling any number on a six-sided die is  7/42 or 1/6.

Now we can calculate the probability of each side by substituting the value in the table into the equation:

P(E) = n(E)/n(S)

P(1) = 7/42

      = 1/6

P(2) = 6/42

      = 1/7

P(3) = 14/42

      = 1/3

P(4) = 4/42

      = 2/21

P(5) = 6/42

      = 1/7

P(6) = 5/42

Thus, the experimental probability of rolling each is P(1) = 1/6, P(2) = 1/7,  P(3) = 1/3,  P(4) = 2/21,  P(5) = 1/7, and P(6) = 5/42.

Answer:

There is not enough evidence to support the claim that the fat percentage of at least one of the four ethnic groups is different.

Step-by-step explanation:

The Analysis of Variance (ANOVA) test is used to determine whether there is any significant difference between the mean of various independent groups.

In this case an ANOVA test is being performed to determine whether the fat percentage of four different ethnic groups are different or not.

The hypothesis can be defined as:

H₀: The fat percentage of four different ethnic groups are same, i.e. μ₁ = μ₂ = μ₃ = μ₄.

Hₐ: The fat percentage of at least one of the four ethnic groups is different, i.e. at least one μ\(_{i}\) is different.

The significance level of the test is, α = 0.05.

The decision rule is:

The p-value of the ANOVA test is computed as, p-value = 0.11.

p-value = 0.11 > α = 0.05.

The null hypothesis was failed to be rejected.

Hence, it can be concluded that there is not enough evidence to support the claim that the fat percentage of at least one of the four ethnic groups is different.

The class had cleaned x × A square miles before lunch.

Let's assume that the area of the park is A square miles, and the portion of the park cleaned by Mai's class before the lunch break is represented by x (a fraction or decimal between 0 and 1).

If the class had cleaned x portion of the park, then the area they had cleaned is x times the total area of the park:

Area cleaned before lunch = x × A

Since x represents a fraction or decimal, multiplying it by the total area A gives us the corresponding portion of the park that was cleaned.

Let's say the park has an area of A square miles, and the area that Mai's class cleaned up before lunch is denoted by the number x (a fraction or decimal between 0 and 1).

If the class had cleaned a certain percentage of the park, their cleaned area would be x times the park's overall area:

Before lunch, the area was cleaned = x A

We may calculate the proportion of the park that was cleaned by multiplying x by the entire area A because it indicates a fraction or decimal.

Answer:

When the  sample size is  \(n_1 = 5\) ,

   \(P( X < 11) = 0.9875\)

When the  sample size is  \(n_2 = 6\) ,

   \(P( X < 11) = 0.993\)

Step-by-step explanation:

From the question we are told that

  The mean is  \(\mu = 9 \ min\)  

   The standard deviation is \(\sigma = 2 \ min\)

    The first sample size is  \(n_1 = 5\)

    The second sample size is  \(n_2 = 6\)

Generally the standard error of the mean is mathematically represented as

     \(\sigma_{x} = \frac{\sigma}{ \sqrt{n} }\)

=>   \(\sigma_{x} = \frac{2}{ \sqrt{5} }\)  

When the  sample size is  \(n_1 = 5\) ,

Generally the standard error of the mean is mathematically represented as

     \(\sigma_{x} = \frac{\sigma}{ \sqrt{n} }\)

=>   \(\sigma_{x} = \frac{2}{ \sqrt{5} }\)  

=>   \(\sigma_{x} = 0.894\)  

Generally the probability that the sample average amount of time taken on each day is at most 11 min is mathematically represented as

      \(P( X < 11) = P( \frac{X - \mu }{\sigma } < \frac{11 - 9 }{0.8944 } )\)

\(\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )\)

      \(P( X < 11) = P( Z < 2.24 )\)

From the z table  the area under the normal curve to the left corresponding to  2.24 is

      \(P( Z < 2.24 ) = 0.9875\)

=>   \(P( X < 11) = 0.9875\)

When the  sample size is  \(n_2 = 6\) ,

Generally the standard error of the mean is mathematically represented as

     \(\sigma_{x} = \frac{\sigma}{ \sqrt{n} }\)

=>   \(\sigma_{x} = \frac{2}{ \sqrt{6} }\)  

=>   \(\sigma_{x} = 0.816\)  

Generally the probability that the sample average amount of time taken on each day is at most 11 min is mathematically represented as

      \(P( X < 11) = P( \frac{X - \mu }{\sigma } < \frac{11 - 9 }{0.816 } )\)

\(\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )\)

      \(P( X < 11) = P( Z < 2.45 )\)

From the z table  the area under the normal curve to the left corresponding to  2.24 is

      \(P( Z < 2.45 ) = 0.993\)

=>   \(P( X < 11) = 0.993\)

Answer:

y = 3/5x + -9

or y = 3/5x - 9

Step-by-step explanation:

Since you are already given the slope for this equation all you have to do is plug in the ordered pair in this equation: y = mx+b

Here is what this equation stands for:

y = the y in the order pair you are given, in this case it would be -6

m = This is the slope, sometimes you may not be given the slope so you would have to find it, but in this case, you are given it, the slope is 3/5

x = the x in the ordered pair you are given, in this case it would be 5

b = This is the y-intercept, you will mostly be solving for this most of the time

(5,-6)

(x, y)

y = mx+b (Use this Formula)

-6 = 3/5(5) +b (The numbers have been substituted within the formula)

-6 = 3+b (simplify the equation by multiplying the slope by the x)

-6-3 = b ( once simplified the left side of the equation, go to the right side, but remember when you do that you have to change the sign because you are eliminating 3 on the left side completely, "what you do on one side, do it to the other side")

-9 = b (solve)

y = 3/5x + -9 (plug in the slope and B(y-intercept) within the formula - y = mx+b, make sure that you are not plugging in x and y for this step)

Answer:

The first 5 months Paul paid $ 15.50, and in the next 7 months he paid $ 24.

Step-by-step explanation:

Since Paul signs up for a new cell phone plan, and he is offered a discount for the first five months, and after this period, his rate increases by $ 8.50 per month, and his total cost at the end of the year is $ 245.50, and Paul wrote the following equation to represent his plan: 5x + 7 (x + 8.50) = 245.50; To determine the value of X, the following calculation must be performed:

5X + 7 x (X + 8.50) = 245.50

5X + 7X + 59.50 = 245.50

12X + 59.50 = 245.50

12X = 245.50 - 59.50

12X = 186

X = 186/12

X = 15.50

Therefore, the first 5 months Paul paid $ 15.50, and in the next 7 months he paid $ 24.

Step-by-step explanation:

[# of donuts] 2 → [total price] $1

[# of donuts] 12 → [total price] $6

[# of donuts] 3 → [total price] $1.50

[# of donuts] 7 → [total price] $3.50

Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.

Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.
