Answer:
0.8
Step-by-step explanation:
The question here says that In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B.
Since the question says that 18 out of 30 students are men,6 out of the remaining people earn a "B" and non of the 18 men earn a "B".
The probability of picking a man or a person that earns a "B" is
18/30 (since there are 18 men out of the 30 students)
And 6/30(since there are 6 people that earn a "b")
The probability of picking a man or a "b" earner is
18/30 + 6/30
= 24/30 or 0.8
Answer:
$7826.78
Step-by-step explanation:
Total income = 7950
With a service fee charge of 1.55%, the service fee charge =
Net income = 7950 - 123.225 = 7826.775 = $7826.78
An alternative solution:
Service charge = 1.55%
Net income = (100 - 1.55)% × 7950
= 98.45% × 7950 =
Answer:
C
Step-by-step explanation:
the equation of relationship between x and y in item ll is: y = -x -3
the rate of change of it is -1 that is equal to the rate of change of items l.
Answer:
$115.43
Step-by-step explanation:
From the above question:
1 hour of work = $8.55
13.5 hours of work = x
Cross Multiply
x = 13.5 × $8.55
x = $115.425
Approximately to the nearest hundredth = $115.43
If John works 13.5 hours, the amount of money he makes = $115.43
The function graphed is f(x) = x
