***Number each step 1-8 or 1-9 and show all work 1. A research group believes that female college students have more credit card debt when they graduate from college than male students. Random samples of 320 students were taken for each group. The mean debt for females was $2170 with a standard deviation of $800. The mean debt for male students was $2790 with a standard deviation of $720. At a significance level of 0.05 is there evidence to support the researcher’s belief?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

9x
