***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?

answer: i think it is (1,-2)

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
