Answer:

14^2

Step-by-step explanation:

if you find what is 14 * 14 and then all the answers to the expressions, you will get the answer.

14 * 14 = 196

2 ^ 2 = 8, so that's incorrect

2 ^ 14 = 16,384, definitely incorrect

14 ^ 2 = 196, CORRECT

14 ^ 14 = a huge number we won't even go over.

So, 14^2 is the correct expression

hope this helps! :)

Consider two populations for which μ1 = 31, σ1 = 3, μ2 = 29, and σ2 = 2. Suppose that two independent random samples of sizes n1

DochEvi [55]

Answer:

Part (a): The mean of the distribution is 2.

Part (b): The standard deviation of the distribution is 1.525

Step-by-step explanation:

Consider the provided information.

Part (a) What is the mean of the distribution?

The mean of the sampling distribution of $(\bar x_1 -\bar x_2)$ is (µ₁ − µ₂).

It is given that μ₁ = 31, σ₁ = 3, μ₂ = 29, and σ₂ = 2.

Mean of distribution = (x₁ - x₂)

Mean of distribution = (31 - 29) = 2

Hence, the mean of the distribution is 2.

Part (b) What is the standard deviation of the distribution?

If the two samples are independent, the standard deviation of the sampling distribution is: $\sigma_{(x_1-x_2)}=\sqrt{\left(\dfrac{\sigma^2_1}{n_1}+\dfrac{\sigma^2_2}{n_2}\right)}}$

Substitute the respective values in the above formula.

$\sigma_{(x_1-x_2)}=\sqrt{\left(\dfrac{3^2}{4}+\dfrac{2^2}{53}\right)}}$

$\sigma_{(x_1-x_2)}=\sqrt{\left(\dfrac{9}{4}+\dfrac{4}{53}\right)}}$

$\sigma_{(x_1-x_2)}\approx1.525$

Hence, the standard deviation of the distribution is 1.525

Two angles are complementary. If the measure of angle 1 is 24.2○,what is the measure of angle 2?

azamat

63.8, subtract 24.2 from 90 to get your answer since complementary means 90 degrees and supplementary means 180 degrees. Hope this helped! :)
