Aileen lists the quiz scores for random samples of seventh grade
School X: 70, 72, 74, 84, 89, 89, 93, 94, 95, 100
School Y: 67, 68, 72, 80, 86, 86, 88, 90, 90, 96
How much greater is the interquartile range of the quiz scores for the School X
mple than the
for the School Y sample?

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

this is answer of 144 cubic meters

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
