First of all, you would make 6 1/4 into an improper fraction. This makes it 25/4, then you multiply it by 2 to get 50/8 and have common denominators. Divide that by 1/8, which would be 50. Then since each 1/8 costs 2 dollars you would multiply 50 by 2. So, the answer would be that they made 100 dollars.
Answer:
6.68% of the female college-bound high school seniors had scores above 575.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 500
Standard Deviation, σ = 50
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:
P(scores above 575)
P(x > 575)
Calculation the value from standard normal z table, we have,
6.68% of the female college-bound high school seniors had scores above 575.

Answer: p = 0.56
Step-by-step explanation: from the question, probability she passed the first course = 0.7
Probability she passed the second course = 0.8
Probability she passes both courses means probability she passes the first course "and" probability she passes the second course.
Probability she pass both courses = 0.7 * 0.8 = 0.56
Note that "and" in probability means multiplication.
