Answer:
0.0087 probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is the probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random?
There are 5 freshman non-Statistics majors out of 102 students.
Then, there will be 18 junior statistics majors out of 101 students(1 will have already been chosen). So

0.0087 probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random

Answer:
k = 3
Step-by-step explanation:
Given that y and x are directly related then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 81 when x = 27
k =
=
= 3
The answer would be option B "he was given $50 for his birthday."
Here is how:
Y=
^
Y equals the amount of money in the account.
75$+50$=
75x represents the amount of money he DEPOSITS which is in the question.
So if he deposits 75$ a week (which represents X) and he adds 50$ to it which means he has 50$ to begin with which means he got 50$ for his birthday.
Also....
Because 75x already represents X therefore it wouldn't be options A, C or D.
Hope this helps!
