Using the normal distribution, it is found that the sections that are one standard deviation from the mean are 34 and 40.

<h3>Normal Probability Distribution</h3>

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

Z = \frac{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.

The mean and the standard deviation are given, respectively, by:

\mu = 37, \sigma = 3

The measures that are one standard deviation from the mean are given by X when Z = -1 and Z = 1, hence:

Z = \frac{X - \mu}{\sigma}

-1 = \frac{X - 37}{3}

X - 37 = -3

X = 34

Z = \frac{X - \mu}{\sigma}

1 = \frac{X - 37}{3}

X - 37 = 3

X = 40

Given the following​ function, find f(−5), f(0), and f(4). f(x)=x2+5
bulgar [2K]

Answer:

30, 5 , 21

Step-by-step explanation:

substitute the values of x into f(x) , then

f(- 5) = (- 5)² + 5 = 25 + 5 = 30

f(0) = 0² + 5 = 0 + 5 = 5

f(4) = 4² + 5 = 16 + 5 = 21
