Well, in 12 minutes, you'd have decorated 3/4 of a cupcake 12 times. In other words, 3/4x12/1. The answer would be 36/4, or 9 whole. In 12 minutes, Paul would have decorated 9 whole cupcakes.
Answer:
(- 2, 9 )
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
y = - x² - 4x + 5 ← is in standard form
with a = - 1 and b = - 4, thus
= - = - 2
Substitute x = - 2 into equation for corresponding y- coordinate
y = - (- 2)² - 4(- 2) + 5 = - 4 + 8 + 5 = 9
vertex = (- 2, 9 )
Your answer is b because 95% of data is ideally with 2 deviations from the mean and 99.9% of data is within 3 deviations from the mean.
