Answer:
a) 395.725
b) 378.75
c) 8.8
Step-by-step explanation:
a) S(8.5) = 11.25(8.5) + 300 = 395.625
b) if she worked 47 hrs, that means there were 7 overtime, h=7 and we have to find S(7).
S(7) = 11.25(7) + 300 = 378.75
c) her salary was 398.61, that means S(h) = 398.61 and we have to find h.
398.61 = 11.25(h) + 300
98.61 = 11.25(h)
h = 98.61 / 11.25
h= 8.8

Answer:
10.
Step-by-step explanation:
x^2 + 5x = 150
x^2 + 5x - 150 = 0
This equation will factor:
(x - 10)(x + 15) = 0
x - 10 = 0 or x + 15 = 0, so:
x = 10 or -15.
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%
2. Probability of the mail being delivered before 2 pm for 2 consecutive days is
