You can start by writing equations with the given information
1) You know that together, Mindy and Troy ate 9, so you can write
M+T=9
2) Then, it says that Mindy ate 3, so M=3
3) Troy ate 1/4 of the total cake, however we don't know what the amount of the total cake is, so we can represent it as x, T=1/4x
4) Plug in these equations into the first equation, 3+1/4x=9
5) Solve for X, Subtract 3 from both sides to get 1/4x=6
6) Divide 1/4 on both sides, x=(6÷1/4)
x=24
Hope this helped :)
Please include the specified variable to solve for in this equation.

Given:
Population mean, μ = 10
Population standard deviation, σ = 1.5
Random variable, x = 11.
By definition, the z-score is
z = (x - μ)/σ
= (11 - 10)/1.5
= 0.667
Answer: 0.667
