Answer:
-272
Step-by-step explanation:
8 large red, 5 small red, 7 large blue, 4 small blue:
totally = 24 marbles
P(red)= 13/24
let A red and B large
P(A/B)= P(A∩B)/P(B)
P(B)= 15/24 =.625
P(A∩B)= 8/24 = .333
P(A/B) =.333/.625 =.533
P(B/A) =.625/.333= 1.875
so the probability of p(large/red) is larger.
Answer:
(C) They are the same
Step-by-step explanation:
The coefficient of variation CV is given by the following formula:
In which 
is the standard deviation and 
is the mean.
Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds
This means that 
.
So his coefficient of variation is
Mary's weight has a mean of 125 pounds with a standard deviation of 10 pounds.
This means that 
So her coefficient of variation is
They have the same coefficient of variation, so the correct answer is.
(C) They are the same
We write the expressions first mathematically:
three divided by one-fifth:
(3) / (1/5)
one-fifth divided by three:
(1/5) / (3)
We now use the double c method to find the results:
(3) / (1/5) = (3 * 5) / (1 * 1) = 15/1 = 15
(1/5) / (3) = (1 * 1) / (5 * 3) = 1/15 = 0.066666667
The difference between the two is:
15-0.066666667 = 14.93333333
Answer
They are different because they are inverse expressions.
