Yes. The answer is
$8 \sqrt{15}$
multiply the like terms

2×4 is 8
$\sqrt{3} \times \sqrt{5} = \sqrt{15}$
which can't be reduced any further ....("In case you need to solve another like it during the assessment.")

Line segments JK and JL in the xy-coordinate plan both have a common endpoint J(-4,11) and midpoints at M1 (2,16) and M2 (-3,5),

OleMash [197]

The first part of the question is not needed
we only need to know M1 and M2
(y2-y1)^2+(x2-x1)^2=(your answer)^2
(5-16)^2+(-3-2)^2=(your answer)^2
(-11)^2+(-5)^2=(your answer)^2
121+25=(your answer)^2
146=(your answer)^2
√146=12.0830459735945721
nearest tenth=12.1

HELP PLEASE:

Answer: Mean of the sample proportion = 74.4

Standard deviation of the samnple proportion is 5.32.

Step-by-step explanation:

Given : A random sample of 120 is taken from a population of 10000.

Let n = 120

Also, from previous survey, it is believed that 62% of the population has an Instagram account.

i.e, population proportion : p = 0.62

Now , the mean of the sample proportin would be :

$\text{Mean}=\mu_{\hat{p}}=np\\\\=120\times0.62=74.4$

i.e. Mean of the sample proportion = 74.4

The standard deviation of the samnple proportion would be :

$\text{standard deviation}=\sigma_{\hat{p}}=\sqrt{np(1-p)}\\\\=\sqrt{120(0.62)(1-0.62)}\\\\=\sqrt{28.272}\\\\=5.31714208951\approx5.32$

Thus , the standard deviation of the samnple proportion is 5.32.
