Answer:

Step-by-step explanation:

z value of 14.9 = (16.3 - 14.9) / 2

= 0.7

= .7580

z value of 12.9 = (16.3 - 12.9) / 2

= 1.7

=.9554

Required probability = .9554 - .7580

= .1974

or 19.74 % .

I forgot to do slopes

Minchanka [31]

To find the slope of the line, use the rise over run formula:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Take any two points from the line and plug them into the formula.

(0,0) and (10, 5)

$\frac{5 - 0}{10 - 0} = \frac{5}{10} = 0.5$

The slope of the line is 0.5.

Using the form y = mx, the following equation will be your answer:

$y = 0.5x$
