Answer:
A. Probability = 0.02
B. This is in a cumulative frequency table in the attachment I added
Step-by-step explanation:
A. We have these following probabilities
Prob(X=0) = 0.05
Prob(x= 2) = 0.30
Prob(X = 4) = 0.50
Prob(X < 2) = Prob(X=0) + prob(X=1)
0.18 = 0.05 + prob(X=1)
prob(X=1) = 0.13
A. Prob(x = 3)
= 1 - (0.05 + 0.13 + 0.30 + 0.50)
= 0.02
Probability of buying only 3 times = 2%
B. The cumulative frequency is in the attachment.
Answer:

x=5.5
Answer:
The last one
Step-by-step explanation:
It hits the y-intercept by 2, and moves left 3 and up 2
Let the two numbers be x and y. The sum of x and y is 14 and the difference is 20. We can write a system of equations and solve:
Then substitute x back into one of the equations to find y:
So the two numbers are 17 and -3
