Answer:

(D) I think

Step-by-step explanation:

Lets look at our answer choices; A.

The intervals are not comparable. The shorter bar spans more than 10 years. When it comes to a horizontal axis it doesn't matter how far it expands,just if it's expanded correctly.

B.The intervals are appropriately labeled. There not it goes from 25 to 50 in just in instant few climbs up.

C.The intervals are not comparable, but the data on the graph is not misleading. It is misleading the graphs are incorrectly labeled.

Which brings us to our answer D.The vertical axis does not have an appropriate scale. it goes from 0-25 25-50 and 50-75 then 75-100. that's a short distance for such numbers that are pretty far apart.

I hope I'm right and I hope this helps:)!

<h3>Answer:</h3>

-36

<h3>Step-by-step explanation:</h3>

The applicable rule of exponents is ...

... (a^b)^c = a^(b·c)

Here, you have a=m, b=?, c=1/3, b·c = -12, so you can write ...

... b·(1/3) = -12

Multiply by 3.

... b = -36

The exponent of m inside parentheses is -36.

The time needed to complete a final examination in a particular college course is normally distributed with a mean of minutes an

Andrej [43]

Answer:

a. This probability is the p-value of Z when X = 60.

b. This probability is the p-value of Z when X = B subtracted by the p-value of Z when X = A.

c. The proportion is the p-value of Z when X is the length of the examination period. How many students is this proportion multiplied by the number of students.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

Mean $\mu$ , standard deviation $\sigma$ .

a. What is the probability of completing the exam in one hour or less (to 4 decimals)?

This probability is the p-value of Z when X = 60.

b. What is the probability that a student will complete the exam in more than minutes A but less than B minutes (to 4 decimals)?

This probability is the p-value of Z when X = B subtracted by the p-value of Z when X = A.

c. Assume that the class has students and that the examination period is minutes in length. How many students do you expect will be unable to complete the exam in the allotted time (to nearest whole number)?

The proportion is the p-value of Z when X is the length of the examination period. How many students is this proportion multiplied by the number of students.

F(x) = 2x – 1 g(x) = 7x – 12 What is h(x) = f(x) + g(x)?

Liula [17]

<h2>Hello!</h2>

The answer is:

$h(x)=9x-13$

To solve the problem, we need to perform the shown operation.

We have the functions:

$f(x)=2x-1\\g(x)=7x-12$

So, performing the following operation, we have:

$f(x)+g(x)=h(x)$

$h(x)=f(x)+g(x)=(2x-1)+(7x-12)=7x+2x-1-12=9x-13$

$h(x)=9x-13$

Hence, we have that the correct option is:

A. $h(x)=9x-13$

Have a nice day!
