1. During October, William Korth worked 160 regular time hours at $9.28 an hour and 18 overtime hours at time-
Vanyuwa [196]

Answer:

Kindly check explanation

Step-by-step explanation:

1.) regular time hours = 160

Overtime hours = 18

Gross pay = (9.28 * 160) + (1.5 * 9.28 * 18) = $1735.36

2.) Last year, Ida Zolen worked 2,000 hours at regular time pay of $8.20 an hour. She also worked 75 hours over time at double his regular rate. What was Ida’s gross pay last year?

Gross pay:

(2000 * 8.20) + (2 * 8.20 * 75) = $17,630

3. Alan Kirbaum works on an 8-hour day basis and is paid $8 an hour for regular time work and time-and-a half for overtime work. Last week he worked these hours: Monday:9 ; Tuesday:6 ; Wednesday:11 ; Thursday:8 ; Friday:9.

A) How many regular hours did he work?

Regular hours = (8 + 6 + 8 + 8 + 8).= 38 hours

B) How many overtime?

Overtime = (1 + 3 + 1). = 5 hours

C) What is his overtime rate?

2.5 * $8 = $20

D) What is his overtime pay?

$20 * 5 = $100

E) Find Alan’s gross pay.

(38 * $8) + $100 = $404

4. Stephen Woll’s regular pay is $20 an hour. He is paid time and a half for overtime work beyond 40 hours a week. He

worked: Monday:11 ; Tuesday:10 ; Wednesday:10 ; Friday:12. Find Stephen

Total Hour = (11 + 10 + 10 + 12) = 43 hours

The probability that Billy would pass at least one test is 0.9. The probability that he passes both tests is 0.7. The tests are
allsm [11]

Answer:

0.875

Step-by-step explanation:

Let the probability that Billy passes test 1 be P(A)

Let the probability that Billy passes test 2 be P(B)

P(A n B) = 0.7

P(A) = P(B)

Let them both be numerically x.

P(A) = P(B) = x

P(A') = P(B') = (1 - x)

Probability that he passes at least one test = 0.9

But (probability that he passes at least 1 test) = 1 - (Probabilty that he fails both tests)

Probability that he fails both tests = 1 - 0.9 = 0.1

P(A' n B')= 0.1

P(U) = P(A) - P(A n B) + P(B) - P(A n B) + P(A n B) + P(A' n B') = 1

x - 0.7 + x - 0.7 + 0.7 + 0.1 = 1

2x = 1 + 0.7 - 0.1 = 1.6

x = 0.8

P(A) = P(B) = 0.8

The conditional probability of Billy passing test 2 given the event that he passes test 1 = P(B|A) = P(A n B)/P(A) = (0.7/0.8)

P(B|A) = 0.875

Hope this helps!!!
