a) There is no significant difference between restaurants with and without order-confirmation boards
b) -12.5 ± 3.604 or C.1.E (-16.10, -8.90)
Step-by-step explanation:
answers are in the attachment below
First you'll have to bring the equation in form y = mx + b.
4y = -x - 32
y = -1/4 x - 8
So the slope is -1/4 and y-intercept is -8
Hope this helps :)
Answer:
A = 4 pi R^2 V = 4/3 pi R^3
A / V = 3 / R
Also, R = (3 * V / 4 * pi)^1/3 = (3 * 904.32 / (4 * pi))^1/3 = 6 in
So A = 3 / 6 * V = 1/2 * 904.32 = 452.16 in^2
