Answer:
6 weeks
Step-by-step explanation:
Easier way to solve: If she takes 7 quizzes each week, 7 times something (amount of weeks) equals 42.
7 X <u>6</u> = 42
Solving with algebra: We know that hanna takes six quizzes a week and takes a total of 42 quizzes, therefore the unknown (x) is the amount of weeks she takes the quizzes.
Amount of weeks X amount of tests per weeks = 42 quizzes
<em>x </em>X 7 = 42
42/7 = 6
Answer:
Probability=0.8413
So option A is correct.
Step-by-step explanation:
In order to find the probability that the criminologist will classify all of them as delinquents, we will proceed as following:
We are required to find:
P(m>=75|m-N(80,5))
it can be written as:
1-P(m<75|m-N(80,5))
P(m<75|m-N(80,5)) can be solved as
Z=(75-80)/5
Z=-1
Probability = 1-Z(-1)
Fromm distribution table:
Probability=1-0.15866
Probability=0.8413
So option A is correct.
