Using an absolute-value inequality, describe the set of numbers whose distance from 4 is greater than 5 units. Draw a graph of t
1 answer:
The solution to the absolute-value inequality is x > 9; and x < -1
<h3>What is an inequality?</h3>An inequality is an expression that shows the nonequal comparison of two or more numbers and variables.
Let x represent the unknown number, hence:
|x - 4| > 5
(x - 4) > 5; and -(x - 4) > 5
x > 9; and x < -1
The solution to the absolute-value inequality is x > 9; and x < -1

Answer:
a) The probability of selling less than 100 gallons (x≤1) is P=0.16.
b) The mean number of gallons is M=80 gallons.
Step-by-step explanation:
The probability of selling x, in hundred of gallons, on any day during the summer is y(x)=0.32x, in a range for x from [0;2.5].
The probability of selling less than 100 gallons (x≤1) is then:
The mean number of gallons can be calculated as:
