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%.
Depends
it can be a trinomial example
(x-3)(x-4)=x²-7x+12
it can be a binomial example
(x-3)(x+3)=x²-9
depends
1st week - Lost 3 pounds = +3
2nd week - Gained 1 pound = -1
3+13 = + 22
So 22+3 = 25 25-1 = 24
So Tina lost 24 pounds in 13 weeks.
Answer:
E. 5
Step-by-step explanation:
Let's rewrite the equation in the form of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
2x + y = 5
y = -2x+5
M, the slope, is -2
<u>5, b, is the y-intercept</u>

Answer:
Step-by-step explanation:
Given
The attached graph
Required
Determine the range of the graph
First, we list out the coordinate of each point on the graph:
The points are:
A function has the form: (x,y)
Where
y = range:
From the coordinate points above,
Order from least to greatest"
Hence, the range are:
