Answer:
A Cumulative probability distribution for the number of tires bought is prepared below.
Step-by-step explanation:
We are given that Sixty percent of the customers who go to Sears Auto Center for tires buy four tires and 22% buy two tires. Moreover, 12% buy fewer than two tires, with 6% buying none.
The cumulative probability distribution for the number of tires bought is given by;
<u>No. of tires</u> <u>Probability Distribution</u> <u>Cumulative Probability</u>
<u>Distribution</u>
0 6% 6%
1 6% 12%
2 22% 34%
3 6% 40%
4 60% 100%
Now, here we are given within the question about:
P(0 tires) = 6%
P(2 tires) = 22%
P(4 tires) = 60%
Also, P(Fewer than 2 tires) = 12% which means P(0 tires) + P(1 tire) must be equal to 12%. So, P(1 tire) = 12% - 6% = 6%.
And, in the end P(3 tires) = 100% - 6% - 6% - 22% - 60% = 6%.
Shape A is congruent to Shape B because If you were to rotate one of the two and flip it the would like up and match.
-3(b - 7)
Multiply -3 into the parenthesis.
= -3b + 21.
Step-by-step explanation:
It's 6r+5y. But it's not in the option
Quantity of gasoline needed by a car to run 800 miles = 30 gallons
Quantity of gasoline needed by a car to run 1 mile =
= 30 ÷ 800
= 0.0375 gallons
So , to run 1 mile a car would need = 0.0375 gallons of oil
To run 700 miles the quantity of gasoline needed =
= 700 × 0.0375
= 26.25 gallons of gasoline
Therefore , a car will use 26.25 gallons of gasoline on a trip of 700 miles .
