Answer:
x = 1.5
y = 0
Step-by-step explanation:
10x + 5(2x - 3) = 15
10x + 10x - 15 = 15
20x - 15 = 15
20x = 30
x = 1.5
y = 2(1.5) - 3
y = 3 - 3
y = 0
Check:
10(1.5) + 5(0) = 15
15 + 5(0) = 15
15 + 0 = 15
15 = 15
Answer:
the value of x is 2.
Step-by-step explanation:
5(3x - 4) = 2(2x + 1)
15x - 20 = 4x + 2
15x - 4x = 2 + 20
11x = 22
x = 22/11
x = 2
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:
