Answer:

If the marginal revenue exceeds the marginal cost, then the firm can increase profit by producing one more unit of output. For example, at an output of 4 in Figure 3, marginal revenue is 600 and marginal cost is 250, so producing this unit will clearly add to overall profits.

Answer:

d. 23

Step-by-step explanation:

Let the number of cars be x and buses be y

Then we have below inequalities as per given:

5x + 32y ≤ 1310
x + y ≤ 135

It is easy to notice that cars occupy 6 times less area than buses but cost of parking is 3 times less. So we would need maximum number of cars and minimum number of buses to maximize income

Let's assume there are 135 cars and buses, then from the second inequality:

x = 135 - y

Substitute it in the first one:

5(135 - y) + 32y ≤ 1310
675 - 5y + 32y ≤ 1310
27y ≤ 1310 - 675
27y ≤ 635
y ≤ 635/27
y≤ 23.5

The greatest number of buses is 23

Option D. 23 is correct

When it is operating properly, a chemical plant has a daily production rate that is normally distributed with a mean of 885 tons

-BARSIC- [3]

Answer:

The test statistic Z = 1.844 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

Yes he is right

The manager claims that at least 95 % probability that the plant is operating properly

Step-by-step explanation:

Explanation:-

Given data Population mean

μ = 885 tons /day

Given random sample size

n = 60

mean of the sample

x⁻ = 875 tons/day

The standard deviation of the Population

σ = 42 tons/day

Null hypothesis:- H₀: The manager claims that at least 95 % probability that the plant is operating properly

Alternative Hypothesis :H₁: The manager do not claims that at least 95 % probability that the plant is operating properly

Level of significance = 0.05

The test statistic

$Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{875 -885}{\frac{42}{\sqrt{60} } }$

$Z = \frac{-10}{5.422} = -1.844$

|Z| = |-1.844| = 1.844

The tabulated value

$Z_{\frac{0.05}{2} } = Z_{0.025} = 1.96$

The calculated value Z = 1.844 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

Conclusion:-

The manager claims that at least 95 % probability that the plant is operating properly

How long does it take for a car traveling at a speed of 50.0 miles per hour to travel 300 feet?

beks73 [17]

We know, Time = distance / speed
t = 0.0568182 / 50 [ 300 Feet = 0.0568182 miles ]
t = 0.001136 * 3600 s
t = 4.09 sec

In short, Your Answer would be 4.09 Seconds

Hope this helps!

Which expression is equivalent to 6n-27

Grace [21]

Answer:

3(2n-9)

Step-by-step explanation:

used distributive property

6n - 27 = (3 · 2n) - (3 ·9)

6n - 27 = 3(2n - 9)
