Human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -

STALIN [3.7K]

Answer:

$97.27^{o}F$

Step-by-step explanation:

We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.

To find Sally's temperature we will use z-score formula.

$z=\frac{x-\mu}{\sigma}$ , where $\mu$ = Mean, $\sigma$ = Standard deviation.

Let us substitute our given values in z-score formula.

$-1.5=\frac{x-98.20}{0.62}$

Multiply 0.62 to both sides of equation.

$0.62\times-1.5=0.62\times \frac{x-98.20}{0.62}$

$-0.93=x-98.20$

Add 98.20 to both sides of equation.

$-0.93+98.20=x-98.20+98.20$

$97.27=x$

Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.

The sides of the base of this square right prism are 16 centimeters each and the height of the prism is 10 centimeters. What is

Montano1993 [528]

The width (W) of the prism is 16 cm.

The length (L) of the prism is 16 cm.

The height (H) of the prism is 10 cm.

The formula for the surface area of any right prism with width W, length L, and height H is the following:

A = 2 (WL + LH + WH)

Substituting using our given values changes the equation to:

A = 2 (16*16 + 16*10 + 16*10)

= 2 (256 + 160 + 160) = 2 (576)

= 1152

Thus, the surface area is 1152 cm².

Let me know if you need any clarifications, thanks!
