Maria has three children. there is two years age difference between each child. the total ages of all three children is 36 years
BaLLatris [955]
T= Tina's age
t+2= second child
t+4= third child
36= age of all children

Add the ages of all children equal to 36 years. Add 2 to each age because there is 2 years age difference between each child.

t + (t+2) + (t+4)= 36
combine like terms
3t + 6= 36
subtract 6 from both sides
3t= 30
divide both sides by 3
t= 10 Tina's age

t+2= 12
(10)+2= 12 age of second child

t+4= 14
(10)+4= 14 age of third child

ANSWER: The formula that will calculate Tina's age is t + (t+2) + (t+4)= 36.

Hope this helps! :)

Answer:

  (b)  $1.15

Step-by-step explanation:

The expected value is the sum of products of payoff and probability:

  $0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05

  = $0 +0.25 +0.20 +0.20 +0.50

  = $1.15 . . . . expected value of the scratch ticket
