Answer:
P(x < 5) = 0.70
Step-by-step explanation:
Note: The area under a probability "curve" must be = to 1.
Finding the sub-area representing x < 5 immediately yields the desired probability.
Draw a dashed, vertical line through x = 5. The resulting area, on the left, is a trapezoid. The area of a trapezoid is equal to:
(average length)·(width, which here is:
2 + 5
----------- · 0.02 = (7/2)(0.2) = 0.70
2
Thus, P(x < 5) = 0.70

ANSWER :
14x-x^2 = 33
Step-by-step explanation:
x(14-x) = 33
14x-(x)^2 = 33
The total bill paid for a person who uses 600 kWh in a month is $60.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let us assume that the utility company charges $0.10 per kWh, hence:
Total charge in a month = 0.10 * 600 = $60
The total bill paid for a person who uses 600 kWh in a month is $60.

Answer:
x = 19
Step-by-step explanation:
Vertical angles are equal
So
7x - 8 = 6x + 11
7x - 6x = 11 + 8
x = 19
