The ratio is always 1:1:√2
The correct answer is: <span>D. The regression line is not a good model because the points in the residual plot form a curve. (i know this because i just passed the test ;) )</span>
Answer:
Step 2
Step-by-step explanation:
The answer should be 15x^2-3x^2y^2+y^4+3y
Hi there! The answer is B.

First we work out the parenthesis, which is easy because we can just remove them.

Now rearrange our expression (in order to collect terms later).

Next up is collecting the terms.

The answer is B.

Answer:
dh = 3 *dV / 130
Step-by-step explanation:
Given:
- volume of punch in bottle = 65 ounce
- volume of punch = v
- increase in height of punch level on dispenser = 1.5 in
Find:
- The change in height of punch in the dispenser in inches, Δh, in terms of the change in the volume of punch in the dispenser in ounces, Δv.
Solution:
We will assume a linear relationship between the increase in punch level dispenser and the increase in volume of dispenser.
h(v) = m*v + h
Where, m is change of height with respect to volume. Hence,
m = dh / dV = 1.5 / 65 = 3 / 130 in / ounce
Hence,
dh = 3 *dV / 130
