Answer:
The answer is attached as an image.
Step-by-step explanation:
- If we assume that the space is 100% of the population then:
88% have something and 12% have nothing.
So within the 88% there are 10% who have TV, 20% who have Radio and 58% who have both TV and Radio.
To determine the marginal cost of the production, one needs to derive the given equation for the cost,
c(x) = 6x4 - 30x3 - 54x2 + x + 2
The derivative of the equation in terms of x is as reflected below.
c'(x) = 24x3 - 90x2 - 108x + 1
Equate the derivative to zero in order to determine the value of x .
c'(x) = 0 = 24x3 - 90x2 - 108 + 1
The value of x from the equation is 4.025.
Substituting x to the original equation,
c(x) = -1254.35 and at c(0) = 2
Answer:
Step-by-step explanation:
- Temperature drop = - 1.6°C / hr
- Time = 4 1/4 hr
<u>Temperature change is:</u>
- -1.6 * 4 1/4 =
- -1.6 * 4.25 =
- - 6.8°C
Both of those numbers are significant, so the answer is 2.
6 and 12 are two common factors
