2. Find the slope of the line between (8, 6) and (20, -14)

Mathematics

Natalka [10]2 years ago
3 0

Answer:

slopee = 5/3

Step-by-step explanation:

The  slope of a line is defined by the rise (the change in y-value) divided by the run (the change in x-value).  Here, the change in y-value is 6 - (-14) = 6 + 14 = 20.  The change in x-value is 20 - 8 = 12.  Therefore, the slope is 20/12 or (simplified) 5/3.

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.
