The length is (3/5 -1/5)=2/5
the height is also 2/5
area: length * height =2/5 *2/5=4/5
D is correct.
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:

Answer: -13
Step-by-step explanation:
2-(3^2)+4-3-7 = -13
Answer:
a - 8
b - 20
c - 40
answer - 40% of 20 is 8
Step-by-step explanation:
20 x .4 = 8
.4 is found by the 40 / 100
