Answer:

(a) Independent variable:  b (number of bags sold)

    Dependent variable:  p(b)  (profit)

(b) 25

(c) 84700

(d) 70

(e) b < 25

Step-by-step explanation:

(a) Independent variable:  b (number of bags sold)

    Dependent variable:  p(b)  (profit)

(b) To break even, set p(b) to zero and solve for b:

⇒ 350b - 8750 = 0

⇒ 350b = 8750

⇒ b = 8750 ÷ 350

⇒ b = 25

(c) Substitute b = 267 into equation and solve for p(b):

⇒ 350(267) - 8750 = 84700

(d) Set p(b) to 15750 and solve for b:

⇒ 350b - 8750 = 15750

⇒ 350b = 15750 + 8750

⇒ 350b = 24500

⇒ b = 24500 ÷ 350

⇒ b = 70

(e) If she breaks even when she sells 25 bags, if she sells less than 25 bags she will have a negative profit. So b < 25

Step-by-step explanation:

12x × 10,000 = 700

x = 700 ÷ (12 × 10,000)

x = 700 ÷ 12,000

x = 0.58%

Answer: A, D

Step-by-step explanation:

We know that the volume of a cone is [tex]V=\frac{1}{3} \pi r^{2} h[/tex], so we want to keep [tex]r^{2}h[/tex]constant.

A: [tex]r^{2}h=6^{2} \cdot 3=108[/tex]

B: [tex]r^{2}h=5^{2} \cdot 6=150[/tex]

C: [tex]r^{2}h=4^{2} \cdot 9=144[/tex]

D: [tex]r^{2}h=3^{2} \cdot 12=108[/tex]

Answer:

64

Step-by-step explanation:

3.2*20=64

Answer:

Multiplying 20 by 320% is the same thing as multiplying 20 by 3.2, or 20(3.2)=64. Hope this helped!

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

This is a slightly special case because x = 4. That means that there is no slope to the line.

Since our parallel line goes through the point (3, 4) the equation will be x = 3 to "match" the slope, or lack of, to the original line.

Using the t-distribution, as we have the standard deviation for the sample, it is found that since the absolute value of the test statistic is greater than the critical value for the two-tailed test, there is enough evidence to conclude that the sample does not come from a population whose mean is 1,600 hours.

At the null hypothesis, it is tested if the mean is of 1600 hours, that is:

[tex]H_0: \mu = 1600[/tex]

At the alternative hypothesis, it is tested if the mean is different of 1600 hours, that is:

[tex]H_1: \mu \neq 1600[/tex]

It is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

In this problem, the values of the parameters are:

[tex]\overline{x} = 1500, \mu = 1600, s = 120, n = 100[/tex]

Hence, the value of the test statistic is:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{1500 - 1600}{\frac{120}{\sqrt{100}}}[/tex]

[tex]t = -8.33[/tex]

Considering a two-tailed test, as we are testing if the mean is different of a value, with 100 - 1 = 99 df and a significance level of 0.01, the critical value is of [tex]t^{\ast} = 1.66[/tex].

Since the absolute value of the test statistic is greater than the critical value for the two-tailed test, there is enough evidence to conclude that the sample does not come from a population whose mean is 1,600 hours.

Answer:

50c-25w=p

Step-by-step explanation:

Let p be Quinn's total points.

c represents the amount that he got right, therefore, earning 50 points per c's that he gets.

w is the amount of points that he loses, therefore we must subtract it from the points that he has gained from the correct questions.

Answer/Step-by-step explanation:

A double prime is a symbol used to distinguish a third quantity x^('') ("x double prime") from two other related quantities x and x^' ("x prime). Double primes are most commonly used to denote transformed coordinates, conjugate points, and derivatives. A double prime is also used to denote the number of arc seconds in an angle measure, or the number of inches in a length.

Answer:

Chad has: $144

Step-by-step explanation:

First we need to get 40% of 240 which we can do by multiplying 240 by 0.40.

240 * 0.40 = 96

Now we can just take what we got for 40% of 240, and then subtract it from 240.

240 - 96 = 144
