a cube, like the one in the picture below, has a width=length=height, all sides are equal.  Now, on this one we know it has a volume of 27 in³.

\bf \textit{volume of a cube}\\\\
V=x^3~\hspace{10em}\stackrel{V}{27}=x^3\implies \sqrt[3]{27}=x\implies 3= x


what happened is, Bethany stayed up late last nite till 2am watching reruns of the Teletubbies, so she needs to take a good nap, is all.

Susan has been thinking about starting her own independent gasoline station. Susan’s problem is to decide how large her station
Hitman42 [59]

The Maximax decision is that Susan should build a very large gas station due to the largest value of row maximums.

<h3>What is a decision table?</h3>

A decision table can be defined as a type of table that is used for the graphical representation of the actions to perform, especially based on given conditions and business level rules.

The decision table for Susan’s problem is shown below:

<u>Size            Good market   Fair market   Poor market    Row maximum</u>

Small              50,000           20,000            -10,000           50,000

Medium          80,000           30,000            -20,000          80,000

Large              100,000          30,000            -40,000          100,000

Very large      300,000         25,000            -160,000         300,000

Thus, the Maximax decision is for Susan to build a very large gas station due to the largest value of row maximums.

For the Maximin decision, we have:

<u>Size            Good market   Fair market   Poor market    Row minimum</u>

Small              50,000           20,000            -10,000           -10,000

Medium          80,000           30,000            -20,000          -20,000

Large              100,000          30,000            -40,000          -40,000

Very large      300,000         25,000            -160,000         -160,000

Therefore, the Maximin decision is that Susan should build a small gas station due to the largest value of row minimums.

For the equally likely decision, we would find the row average:

Row 1 = (50,000 + 20,000 - 10,000)/3 = 20,000.

Row 2 = (80,000 + 30,000 - 20,000)/3 = 30,000.

Row 3 = (100,000 + 30,000 - 40,000)/3 = 30,000.

Row 4 = (300,000 + 25,000 - 160,000)/3 = 55,000.

Hence, the equally likely decision is that Susan should build a very large gas station due to the largest value of row average.

<u>Complete Question:</u>

Even though independent gasoline stations have been having a difficult time, Susan has been thinking about starting her own independent gasoline station. Susan’s problem is to decide how large her station should be. The annual returns will depend on both the size of her station and a number of marketing factors related to the oil industry and demand for gasoline.  After a careful analysis, Susan developed the following table:

a. Develop a decision table for this problem

b. What is the maximax decision?

c. What is the maximin decision?

d. What is the equally likely decision?

$360 simple interest is paid when ​$6000 is borrowed for 9 months. Find the simple interest rate.
yaroslaw [1]

Answer:

6 percent

Step-by-step explanation:

1 ) 360/9 = 40 - 40 dollars earned per month

2) 40 x 12 = 480 - earned per year

3) 6000/9 = 666.67 x 12 = 8000 per year

4) 480/8000 = 0.06 / 6 percent

Lets check: 6000 x 1.06 = 6360 which is the amount of interest she gets paid in 9 months

The sum of three numbers is 62. The second number is equal to the first number diminished by 4. The third number is four times t
Bingel [31]

Answer:

The first variable is 11. The second variable is 7. The third variable is 44.

Step-by-step explanation:

First, make an equation with like variables. Instead of 62=x+y+z, change the equation into 62=x+(x-4)+4x. Then solve for x.

62= 6x-4

66= 6x

11=x

Then plug in x and solve for the other variables.

x=11

y=11-4=7

z=4(11)= 44

ASAP!!!!!!!asap!!!!!!!!!!!! asap asap asap
Yuliya22 [10]

Answer:

7). x = 3.2, AC = 42.8

8). a = 6, YZ = 38

Step-by-step explanation:

It is given in the question that a point B is between A and C of the line segment AC.

⇒ AB + BC = AC

By substituting the values of segments,

5x + (9x - 2) = (11x + 7.6)

14x - 2 = 11x + 7.6

14x - 11x = 7.6 + 2

3x = 9.6

x = 3.2

Therefore, AC = 11x + 7.6

                        = 11(3.2) + 7.6

                        = 35.2 + 7.6

                        = 42.8

Question (8).

If Y is a point between X and Z,

⇒ XY + YZ = XZ

By substituting the measures of these segments given in the question,

(3a - 4) + (6a + 2) = (5a + 22)

9a - 2 = 5a + 22

9a - 5a = 22 + 2

4a = 24

a = 6

Since, length of segment YZ = 6a + 2

                                                = 6(6) + 2

                                                = 38
