You are the operations manager of the Spartan Ice Cream Shoppe that produces its own ice cream. You make and sell five flavors;
Ivanshal [37]

Answer:

(a) 90V + 75C + 70P + 55B + 40R

(b) - You can make up to 200 gallons

- You have to make at least 10 gallons of each flavors

- You cannot make more than 75 gallons of any one flavor

(c)V + C + P + B + R ≤ 200

10 ≤ V, C, P, B, R ≤ 75

(d) 75 gallons of Vanilla, 75 gallons of chocolate, 30 gallons of Pistachio, 10 gallons of Banana and 10 gallons of Rocky Road

Step-by-step explanation:

(a)Let V, C, P, B and R be the number of Vanilla, Chocolate, Pistachio, Banana and Rocky Road ice cream gallons you'd plan to make for the Spartan Ice Cream shop. The profit function would be

90V + 75C + 70P + 55B + 40R

And this is the formula that you are trying to optimize.

(b) The constraints are:

- You can make up to 200 gallons

- You have to make at least 10 gallons of each flavors

- You cannot make more than 75 gallons of any one flavor

(c) The constraint formula:

V + C + P + B + R ≤ 200

10 ≤ V, C, P, B, R ≤ 75

(d)  The solutions of this problem is, you would try to make as much as possible of the ones that generate the most profit, while keep an eyes on the constraints. Knowing this, you would

1. Make 10 gallons of each flavors, so a total of 50 gallons. That leaves you with 200 - 50 = 150 gallons left

2. Of the 150 gallons left, you make an extra 65 gallons for Vanilla (so a total of 75 Vanilla gallons). That leaves you with 150 - 65 = 85 gallons

3. Make an extra of another 65 gallons for the 2nd profit generating flavor, which is Chocolate. That leaves you with 85 - 65 = 20 gallons

4. The last 20 gallons can be used to make Pistachio

In the end, you should make: 75 gallons of Vanilla, 75 gallons of chocolate, 30 gallons of Pistachio, 10 gallons of Banana and 10 gallons of Rocky Road

Which of the following is not a possible r-value <br> (-0.3) <br> (0.3) <br> (-0.6) <br> (1.6)
ryzh [129]
<span>1.6. The Pearson Correlation Coefficient, otherwise known as r-value, must have a value between -1 and 1. It's used to measure how closely related two different variables are. -1 means negative linear correlation, 0 means no linear correlation, and 1 means positive linear correlation.</span>

Hi I’m new can someone help me on this (PLZ NO LINKS)
Ymorist [56]
Complementary angles add up to 90 degrees.
So to find A you would need to add A and B together and equal it to 90 (3x+25+5x-7=90)
Combine like terms together (8x+18=90)
Subtract 18 from night sides (8x=72)
Divide by 8 on both sides (x=9)
Then to find A substitute x into its equation (3(9)+25)=(27+25)=52

A=52 I think

Listed below are the measured radiation emissions​ (in W/kg) corresponding to cell​ phones: A,​ B, C,​ D, E,​ F, G,​ H, I,​ J, a
Sophie [7]

Answer: a. Mean = 0.696364

b. Median = 0.64

c. Midrange = 0.895

d. There is no Mode

e. 2. The maximun data value is the most relevant statistic, because it is closest to the limit of 1.6W/kg and that cell should be avoided.

Step-by-step explanation:

a) Mean is an average number of the data set, calculated by the sum of all the value divided by the quantity of the set:

mean = \frac{0.75+0.22+1.23+0.64+0.54+0.24+0.81+1.57+0.29+1.02+0.35}{11}

mean = 0.696364

b) Median is the middle number in the list of numbers. In this case, since there are 11 elements in the set, the middle number is:

sorted numbers of the data set:

0.22 0.24 0.29 0.35 0.54 0.64 0.75 0.81 1.02 1.23 1.57

median = 0.64

c) Midrange is another type of average number. It is calculated as:

midrange = \frac{high+low}{2}

midrange = \frac{1.57+0.22}{2}

midrange = 0.895

d) Mode is the number that appears most often in the list of numbers. For this data set, each number appears only one time, so there is no mode.

Mode = 0

e) According to the question, cell phone radiation is dangerous when it is higher than 1.6W/kg. The cell phone with the maximum data value (1.57 W/kg) should be avoided, since it is too close to the limit described.

So, the measures of center are not the most important statistic to be observed but the maximum data value.
