a.
what is the probability that the dealer will be fined

b.
what is the probability that the dealership will be dissolved?

Step-by-step explanation:

Given that the management decides to evaluate the satisfaction surveys of its next 40 customers.

Fine if favourable number is between 22 and 26,

Dissolved if fewer than 22 report favourably

Let X be the number of persons who report favourably.

X is binomial with n =40 and p = 0.70

a. Probability that the dealer will be fined

=

b.  the probability that the dealership will be dissolved

=

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
