Suppose both the mean and median of a distribution are 12. Which of these statements is true about the mode of the distribution?. . A.The mode is less than 12.. B.There is not enough information to compare the mode.. C.The mode is equal to 12.. D.The mode is greater than 12.

Answers

Answer 1

Answer: The statement that is true about the mode of distribution is there is not enough information to compare the mode. The correct answer is B.

Answer 2

Answer:

Answer:

C.The mode is equal to 12

Step-by-step explanation:

We are given that

Mean of a distribution= 12

Median of distribution=12

We have to find the true statement about the mode of the distribution.

We know that the relation between mode, mean and median

Mean-mode=3(mean-median)

Substitute the values in the formula then, we get

12-Mode=3(12-12)=3(0)=0

Mode=12

Hence, the mode of the distribution=12

Answer:C.The mode is equal to 12

just use trial and error. PLUS since *the integer x 2* needs to be greater than that *integer + 5*, you already know that the number needs to be greater than 5.

Given the polynomial 2x3 + 18x2 − 18x − 162, what is the value of the coefficient 'k' in the factored form?2x3 + 18x2 − 18x − 162 = 2(x + k)(x − k)(x + 9)

k= ____________

Answers

If you would like to know the value of the coefficient 'k' in the factored form, you can find this using the following steps:

2x^3 + 18x^2 - 18x - 162 = 2 * (x^3 + 9x^2 - 9x - 81) = 2 * (x^2(x + 9) - 9(x + 9)) = 2 * ((x + 9) * (x^2 - 9)) = 2 * (x + 9) * (x - 3) * (x + 3) = 2 * (x + 3) * (x - 3) * (x + 9)

The correct result would be: k = 3.
