taurus [48]

The given functions of <em>f </em>and <em>g</em>, where; $f(x) = \frac{2}{ {x}^{2} }$ , $g(x) = \frac{13}{ {x}^{2} }$ gives the domain of the functions as the option;

a. All non zero real numbers

<h3>How can the domain of the functions be found?</h3>

The given functions are presented as follows;

$f(x) = \frac{2}{ {x}^{2} }$

$g(x) = \frac{13}{ {x}^{2} }$

The given functions have <em>x²</em> as the denominator, therefore;

The domain of the functions are the possible x-values, which gives;

x² = (-x)² = Positive number

At <em>x </em>= 0, we have;

$f(x) = \frac{2}{ {0}^{2} } = \infty$

$g(x) = \frac{13}{ {0}^{2} } = \infty$

The domain is therefore;

a. All non zero real numbers

Arm span is the physical measurement of the length of an individual's arms from fingertip to fingertip. A man’s arm span is appr

Damm [24]

Answer:

The 99th percentile for a man’s arm span is 80.47 inches.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 70, \sigma = 4.5$

99th percentile

X when Z has a pvalue of 0.99. So X when Z = 2.327.

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

$2.327 = \frac{X - 70}{4.5}$

$X - 70 = 2.327*4.5$

$X = 80.47$

The 99th percentile for a man’s arm span is 80.47 inches.
