Answer:

66.14inches

Step-by-step explanation:

pyhtgreom therom

75^2+b^2 = 100^2

5625 + b^2 = 10,000

subtract both sides by 5625

b^2 = 4375

square root both sides

b = 66.14

Answer:

B. 10.9

Step-by-step explanation:

Area of triangle= 1/2*24*h

∠N=90° ⇒ Area of triangle= 1/2*MN*ON

MN²= h²+(24-7)²

ON²= h²+7²

24h=MN*ON
24h= √h²+(24-7)²*√h²+7²
(24h)²=(h²+17²)(h²+7²)

h²=k

576k=k²+289k+49k+289*49
k²-238k+14161=0

k=119

h²=119
h=√119= 10.9

The mean is 47.1 and the standard deviation is 9.5 for a population. Using the Central Limit Theorem, what is the standard devia

MaRussiya [10]

Answer:

The standard deviation of the distribution of sample means for samples of size 60 is of 1.2264.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Standard deviation is 9.5 for a population.

This means that $\sigma = 9.5$

Sample of 60:

This means that $n = 60$

What is the standard deviation of the distribution of sample means for samples of size 60?

$s = \frac{\sigma}{\sqrt{n}} = \frac{9.5}{\sqrt{60}} = 1.2264$

The standard deviation of the distribution of sample means for samples of size 60 is of 1.2264.

How did they get the -5? I got -3

Naya [18.7K]

F(x) = x² - 3x
g(x) = √x - 1

f(g(x))= (√x - 1)² - 3(√x - 1) = (√x - 1)(√x - 1 - 3) =(√x - 1)(√x - 4) =
= √x √x -1*√x -4*√x +4 = x -5√x +4

Answer: x -5√x +4
