Katrina randomly selected 64 students out of her school of 400 students and found that 40 of them want school to start at a later time. with a desired confidence of 99%, which has a z*-score of 2.58, which statements are true? check all that apply. e = z*

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
