I will be really happy if you help me out! :)

Answer/Step-by-step explanation:

#8. Using the geometric mean theorem formula, h = √xy, where,

h = x

x = 4 and y = 16

Plug in the values

x = √(4*16)

x = 8

#9. Using the geometric mean formula, h = √xy, where,

h = y

x = 5 and y = 8

Plug in the values into the formula:

y = √(5*8)

y = √40

y = 6.3 (nearest tenth)

#10. Using the geometric mean formula, h = √xy, where,

h = 18

x = 12 and y = y = ???

Plug in the values into the formula:

18 = √(12*y)

Square both sides

18² = 12y

324 = 12y

Divide both sides by 12

27 = y

y = 27

15% chance.

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
