Consumer Reports indicated that the average life of a refrigerator before replacement is 14 years with a standard deviation of 2
guajiro [1.7K]

Answer:

a.) Average life of a refrigerator

b.) 0.1151

c.) 0.0548

d.) 0.6472225

Step-by-step explanation:

Given that :

Average life before replacement, mean, m = 14 years

Standard deviation, σ = 2 years

A.)

The random variable is the variable which is being measured.

B.) What is the probability that someone will keep a refrigerator fewer than 11 years before replacement?

Fewer than 11 years, P(x < 11)

We need to obtain the Z probability, at P(Z < 11)

The Zscore = (x - mean) / standard deviation

Zscore = (11 - 14) / 2.5 = - 1.2

P(Z < - 1.2) = 0.1151

C.) What is the probability that someone will keep a refrigerator more than 18 years before replacement?

More than 18 years, P(x > 18)

We need to obtain the Z probability, at P(Z > 18)

The Zscore = (x - mean) / standard deviation

Zscore = (18 - 14) / 2.5 = 1.6

P(Z > 1.6) = 0.0548

D.) What is the probability that someone will replace a refrigerator between 8 and 15 years?

P(x < 8)

The Zscore = (x - mean) / standard deviation

Zscore = (8 - 14) / 2.5 = - 2.4

P(Z < - 2.4) = 0.0081975

P(x < 15)

The Zscore = (x - mean) / standard deviation

Zscore = (15 - 14) / 2.5 = 0.4

P(Z < 0.4) = 0.65542

P(Z < 0.4) - P(Z < - 2.4)

0.65542 - 0.0081975 = 0.6472225

George has opened a new store and he is monitoring its success closely.
Nataly_w [17]
(r-c)(3) means that you will simply plug in the value 3 as x in the functions r(x) and c(x) and take the difference of both.

Solving for the value of the functions we'll get:
r(3)= (3)^{2}+5(3)+14=9+15+14=38
c(3)= (3)^{2}-3(3)+14=9-9+4=4
(r-c)(3)=38-4=34

Since the value is positive, we can say that the store will profit in its third month. Knowing that r(x) and c(x) is measured in hundreds of dollars, we can also say that the profit will be $3400.

ANSWER: C. The new store will have a profit of $3400 after its third month in business.
