weekly wages at a certain factory are normally distributed with a mean of $400 and a standard deviation of 50. find the probabil

GalinKa [24]

Answer:

47.5%

Step-by-step explanation:

Find the z-scores:

z = (x − μ) / σ

z₁ = (300 − 400) / 50 = -2

z₂ = (400 − 400) / 50 = 0

300 is 2 standard deviations below the mean, and 400 is 0 standard deviations from the mean.

From the empirical rule, 95% of a normal distribution is between -2 and +2 standard deviations. Since normal distributions are symmetrical, that means half of that is between -2 and 0 standard deviations.

95% / 2 = 47.5%

Find the measure of the exterior angle. *

MatroZZZ [7]

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O \: N}}} }:$

Set up an equation and solve for x :

⋆ $\large{ \bf{(4x + 9) \degree = 2x \degree + (3x - 12) \degree}}$ [ Exterior angle is always equal to the sum of two non - adjacent interior angles ]
