In Triangle EFG, the measure of G=90°, the measure of F=47°,and GE = 50 feet. Find the length of EF to the nearest tenth
of a foot.

Answers

Answer 1

Answer:

Answer:

73.3

Step-by-step explanation:

Using the SOH CAH TOA identity

EF = hypotenuse= x

FG = opposite

GE = adjacent = 50feet

Cos 47 = adj/hyp

Cos 47 = 50/x

x = 50/cos47

x = 50/0.6819

x = 73.32

hence the length of EF is 73.3 feet to the nearest tenth

A basketball player averages 22.5 points scored per game with a standard deviation of 6.2 points. In one game, the number of points the athlete scored was 1.2 standard deviations below his mean. How many points below average was this value?

Answers

Using the normal distribution, it is found that this value was 7.5 points below the average.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = (X - \mu)/(\sigma)$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, the mean and the standard deviation are given, respectively, by:

$\mu = 22.5, \sigma = 6.2$ .

In one game, the number of points the athlete scored was 1.2 standard deviations below his mean, hence Z = -1.2 and the score was of X, so:

$Z = (X - \mu)/(\sigma)$

$-1.2 = (X - 22.5)/(6.2)$

X - 22.5 = -1.2 x 6.2

X = 15.

15 - 22.5 = 7.5.

This value was 7.5 points below the average.
