<h3>Answer: Choice B. y = (x+3)^2 - 1</h3>
============================================
How I got that answer:
The vertex is the lowest point of parabolas that open upward.
(h,k) = vertex
(h,k) = (-3,-1)
h = -3
k = -1
For each of the answer choices, a = 1.
The general template of a quadratic in vertex form is
y = a(x-h)^2 + k
Plug a = 1, h = -3, k = -1 into that equation. Simplify.
y = a(x-h)^2 + k
y = 1(x-(-3))^2 + (-1)
y = (x+3)^2 - 1

Answer:
CI = x ± 2.58 (s / √n)
Step-by-step explanation:
The confidence interval is the mean plus or minus the margin of error. The margin of error is the critical value times the standard error. For a normal distribution, the critical value is the z-score at the given confidence level. The standard error is the standard deviation divided by the square root of the sample size.
CI = x ± z (s / √n)
At 99% confidence, z = 2.58.
CI = x ± 2.58 (s / √n)
First step, divide the total amount recommended by the amount in the juice:
18 / 1.5 = 12
so you will need 12 x 8 = 96 ounces of apple juice total
