Answer:
a. 79
Step-by-step explanation:
Use this theorem
Step-by-step explanation:
If we let the width be w, then the length is w+3.5.
This means that w(w+3.5)=11
w^2 + 3.5w - 11 = 0
2w^2 + 7w - 22 = 0 (multiply both sides by 2)
(2w+11)(w-2)=0
w = -11/2 or w = 2 (disregard w = -11/2 as distance is positive)
This means that w=2, and thus the length is 2+3.5=5.5
Answer:
0.72868
Problem Statement:
23% of the cars a certain automaker manufactures are silver. Below is the probability distribution for the number of
silver cars sold by a car dealer in the next five car sales.
No. of Silver Cars 0 1 2 3 4 5
Probability 0.27068 0.40426 0.24151 0.07214 0.01077 0.00064
Step-by-step explanation:
To find the probability that the dealer sells between one and four silver cars, we need to add the probabilities of him selling 1,2,3 or 4 cars.
<u>Probability that the dealer sells between and including one and four silver cars</u>= 0.27068+ 0.40426 + 0.24151 + 0.07214 =0.72868
