Fifty percent of the customers who go to Sears Auto Center for tires buy four tires and 30% buy two tires. Moreover, 18% buy few

cestrela7 [59]

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.

Which equation has every number as a solution?

ikadub [295]

Answer:

the answer is D

Step-by-step explanation:

the equation works with every number placed where the x is, for example:

4(5+1)= 4×5 + 4

4×6=20+4

24=24

but it also works with

4(11+1)= 4×11 + 4

4×12=44+4

48=48

and it also works with every possible number you can think!
