Mathematics

Answer:

The arc is one-third of the circumference.

Step-by-step explanation:

The area of a circumference = 2πr

C = 2πr ... (1)

If an arc subtends a central angle measuring 2π/3 rad,

The length of the arc = rθ

Given θ = 2π/3

Length of the arc L = r(2π)/3

L = 2πr/3... (2)

L = 1/3(2πr)

Since C = 2πr

L = 1/3C

This shows that the arc is one-third of the circumference.

13.) The heights (in inches) of males in the United States are believed to be approximately normally

Fantom [35]

Answer:

Option C) 0.830

Step-by-step explanation:

We are given the following in the question:

The heights (in inches) of males in the United States are believed to be approximately normally distributed with mean $\mu$ .

Sample size, n = 25

Sample mean, $\bar{x}$ = 69.72 inches

Standard deviation, $\sigma$ = 4.15 inches

We have to find the standard error of $\bar{x}$ .

Standard error =

$\dfrac{\sigma}{\sqrt{n}} = \dfrac{4.15}{\sqrt{25}} = \dfrac{4.15}{5} = 0.83$

Thus, the standard error of $\bar{x}$ is 0.83 inches.

The correct answer is

Option C) 0.830

Find the x and length. Round your answer to the nearest tenth. I need the answer ASAP pls

MA_775_DIABLO [31]

To find x:

use the formula: cos° = adajcent/hypo

cos 37° = x/ 16

answer: 12.8

The other length:

use the same formula

cos 57° = y/16

answer: 8.7
