Answer:
0.4459
Step-by-step explanation:
Let the random age variable, X = 4.5; mean,∪ = 4.8; standard deviation, α = 2.2
By comparing P ( 0≤ Z ≤ 4,8)
P(Z ≤ X - ∪/α) = P(Z ≤ 4.5 - 4.8/2.2) = P(Z ≤ - 0.136)
Using the table: P(0≤ Z ≤ 1) = 0.0541
P(Z > 1) = (0.5 - 0.0541) = 0.4459
∴ P(Z > 4.5) = 0.4459
Answer:
Step-by-step explanation:
Breakeven is the revenue with no profit or loss. The money spent is same as money made.
<h3>Money spent is</h3>
<h3>Money made is</h3>
<h3>Since these are same, the number of pies is</h3>
- 200 + 0.25x = 1.5x
- 1.5x - 0.25x = 200
- 1.25x = 200
- x = 200/1.25
- x = 160
<h3>The revenue is</h3>
- 200 + 0.25*160 =
- 200 + 40 =
- 240
