Answer:
a) -15 unites per dollar
b) -12 units per dollar
c) -18 units per dollar
Step-by-step explanation:
We are given the following in the question:
where N(p) is the number of boxes of nails at p dollars per box.
a) average rate of change of demand for a change in price from $2 to $3.
Average rate of change =
b) instantaneous rate of change of demand when the price is $2
Instantaneous rate =
The instantaneous rate of change of demand when the price is $2 is decreasing at 12 units per dollar.
c) instantaneous rate of change of demand when the price is $3
Instantaneous rate =
The instantaneous rate of change of demand when the price is $3 is decreasing at 18 units per dollar.
Answer:
The answer is letter B, The water level in a bathtub as it drains over time.
Step-by-step explanation:
It is best to learn the meaning of <u>"negative correlation"</u> first.
Correlation- In Mathematics, "correlation" means a measure of the relationship between two variables.
<em>Positive Correlation- </em>when the values of the variables increase together.
<em>Negative Correlation- </em>when one value of a variable increases while the other variable's value decreases.
*The situation above is asking for a negative correlation, therefore the answer is letter B (The water level in a bathtub as it drains over time).
The variables are: <u>water level and draining time</u>
As the draining time increases, the water level in the bathtub decreases. This is clearly an example of a negative correlation.
Answer:
48-15 is 33
Step-by-step explanation:
If you're allowed to repeat letters, then it's 12x12x12x12x12. If not, then it's 12x11x10x9x8.
(4 - 5y) - 2(3.5y - 8)
first distribute
(4- 5y) - 7y + 16
Then simplify
-12y + 20
Then simplify
4(-3y + 5)
hope this helps
