For a certain population of sea turtles, 18 percent are longer than 6.5 feet. A random sample of 90 sea turtles will be selected
nika2105 [10]

Answer:

The standard deviation of the sampling distribution of the sample proportion of sea turtles longer than 6.5 feet for samples of size 90 is of 0.0405

Step-by-step explanation:

Central Limit Theorem:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

18 percent are longer than 6.5 feet.

This means that p = 0.18

A random sample of 90 sea turtles

This means that n = 90

What is the standard deviation of the sampling distribution of the sample proportion of sea turtles longer than 6.5 feet for samples of size 90

s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.18*0.82}{90}} = 0.0405

The standard deviation of the sampling distribution of the sample proportion of sea turtles longer than 6.5 feet for samples of size 90 is of 0.0405

HELP PLEASEEE it says solve for x
Vinil7 [7]

Answer:

x = 13

Step-by-step explanation:

the angles are equal.

8x + 2 = 14x - 76

<em>subtract 8x from both sides</em>

8x - 8x + 2 = 14x - 8x - 76

2 = 14x - 8x - 76

2 = 6x - 76

<em>add 76 to both sides</em>

2 + 76 = 6x - 76 + 76

2 + 76 = 6x

78 = 6x

<em>divide both sides by 6</em>

78/6 = 6x/6

78/6 = x

13 = x
