The sample size is the number of people.
You can get the sample size by counting the completion times for each.
Sample size of men = 19
Sample size of women = 34
The mean time is the average time, so you need to add all the times for the men and divide it by the number of men and then the same for the women:
Mean time for men = 3129 / 19 = 164.68 seconds
Mean time for women = 5834 / 34 = 171.59 seconds.
The mean time taken by men is less than the women.
Answer:
750in
Step-by-step explanation:
The area of a triangle is 1/2bh (half x base x height)
Therefore 1/2 x 60in x 25in = 750in

Discussion.
Not directly. But the quadratic formula can do it. But that's not your question.
the factors you get must contain the factors for 1 which are 1 and - 1
These factors must add to - 5. There's no way that will happen with 1 and - 1 and you would be creative math if you tried to say that you could make one of the factors (x -1-1-1-1-1-1). That creates a whole new question.

Did the calculations myself, probably too late for these to be of any use but I'll leaave them here anyways for anyone else that needs it in the future. Love yall!
Answer:
5x-6
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x - 9
f(x) + g(x) = 2x + 3 + 3x-9
= 5x-6
