An SRS of size 20 is drawn from a population that has a normal distribution. The sample has a mean of 122.5 and a standard devia

Tems11 [23]

Answer:

The value is $\sigma_{\= x} = 1.789$

Step-by-step explanation:

From the question we are told that

The sample size is n = 20

The sample mean is $\= x = 122.5$

The standard deviation is $s = 8$

Generally the standard error of the mean is mathematically represented as

$\sigma_{\= x} = \frac{s}{\sqrt{n} }$

=> $\sigma_{\= x} = \frac{8}{\sqrt{20 } }$

=> $\sigma_{\= x} = 1.789$

Type an equation that can be used to solve for the missing angles. DO NOT SOLVE.

muminat

Answer:

x°+2x°+(x-24)°=180°

Step-by-step explanation:

The sum of of the interior angles of all triangles add up to 180°

Adding x°, 2x°, and (x-24)° <em>will</em> equal 180

Therefore, an equation that can be used to solve for the missing angles is: x°+2x°+(x-24)°=180°
