Carol's starting pay for her summer job is $10.25 per hour. Carol earns exactly 3 raises this summer.

zlopas [31]

We know that
1) Carol's starting pay for her summer job is $10.25 per hour
Carol earn per hour=$10.25 per hour

2) For the first rise, she receives a 50 cent-per-hour raise
10.25+0.50=10.75
Carol earn per hour=$10.75 per hour

3) For the second rise, she receives a 10% raise per hour
10.75*1.10=11.825
Carol earn per hour=$11.825 per hour

4) For the third rise, she receives another 50 cent-per-hour raise
11.825+0.50=12.325
Carol earn per hour=$12.325 per hour

5) At the start of next summer. She will be given a 5% raise per hour based on her pay at the end of this summer. 
12.325*1.05=12.94125
Carol will earn per hour=$12.94 per hour

the answer is
$12.94 per hour

the managers of a corporation were surveyed to determine the background that leads to a successful manager. each manager was rat

lubasha [3.4K]

The probability that the selected manager has no college background and only have a fair look is 0.05625

Table is missing. Attached below.

Given,

We have to find the probability that the selected manager has no college background and only have a fair look;

From the table;

The total number of managers surveyed = 160

Number of managers surveyed are fair = 9

Probability;-

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Here,

The probability = Number of managers surveyed are fair / The total number of managers surveyed

The probability = 9/160 = 0.05625

That is,

The probability that the selected manager has no college background and only have a fair look is 0.05625
