Answer:
(3g)×f
Step-by-step explanation:
Since triple g means to multiply g 3 time the equation will be 3g. Then multiplying that product by f will look like (3g)×f. You want the 3g in parenthesis because you want to do that first.
Answer:
I’m not sure I am correct but I think it is either c or d.
Step-by-step explanation:
Answer:
a) (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
Step-by-step explanation:
Given that:
For male students: number of male students (
) = 69, number who liked the new method (x) = 38
For female students: number of female students (
) = 73, number who liked the new method (x) = 20
a) The probability that a male student like the new method (
) is given as:

The probability that a female student like the new method (
) is given as:

c = 95%, α = 1 -c = 0.05

the difference between the proportions of male and female students who like the new method better =
±
=
±
= (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
This means it’s 6(3)^2. The PEMDAS process will help in this situation. Since exponents (E) come before multiplication (M), you would raise 3 to the 2nd power first. 3^2 is the same as 3 times 3, which equals 9. Now, you can multiple 6 by 9, which would result with 54. 54 is your answer!
