Answer:

0.42074

Step-by-step explanation:

In this question, we are asked to calculate the probability that a car will get less than 21 miles per gallon.

This is P(x < 21)

z = 21-22/5 = -1/5 = -0.2

Therefore the probability of getting less than 21 miles per gallon will be;

P(x<21) = P (z < -0.2)

= 0.42074

As per the question,

Kramer Fabrications stockholders' equity at the beginning of July 2017

Stockholders' equity  = $600,000

Net income earned = $145,000

Dividends paid = $25,000

Stockholders' equity at the end of of July 2017

=  Net income - Dividend + Stockholders’ Equity

=  $145,000 - $25,000 + $600,000

=  $720,000

Therefore,

The amount of stockholders' equity at the end of of July 2017 =  $720,000.

Switch the x and y values and isolate y, then simplify.
x=6y+5
6y=x-5
y=1/6x-5/6
