Refer to the completed table for the question referring to children’s shows. what is the marginal distribution of girls? found your answer to the nearest tenth of a percent. type a numerical answer in the space provided. do not include % or spaces in your answer.

on the left middle it would be 50 or 50%

in the middle row on the bottom it would be 110 or 33%

on the left side top it would be 45 and also the same for the row below it or 17%

(I dont know if you wanted the percentages or the actual numbers)

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
