The manager of a grocery store estimates that 74% of customers will make a purchase. Part A: How many customers should a cashier expect until he finds a customer that makes a purchase? Part B: What is the probability that a cashier helps 3 customers until he finds the first person to make a purchase?

a. The number of customers that should a cashier expected till to find a customer is 1.35

b. The probability for helping three customers is 0.013

Step-by-step explanation:

The computation is shown below:

A. The number of customers that should a cashier expected till to find a customer is as follows:

= 1 ÷ 0.74

= 1.35

b. The probability for helping three customers is

= (1 - 0.74)^3 × 0.74

= 0.013

So the same is to be considered and relevant

the answer to the question is a  

it has the same slope and the same y-intercept.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
