Probability     No. of pies          Cost       Revenue      Profit

0.5                        100               500           300            -200

0.25                      150               500           450            -50

0.25                      200              500            600           100

Step-by-step explanation:

We are given that  The owner believes that on 50% of the days she sells 100 pies.

So, Probability of selling 100 pies = 0.5

On another 25% of the days she sells 150 pies

So, Probability of selling 150 pies = 0.25

She sells 200 pies on the remaining 25% of the days

So, Probability of selling 200 pies = 0.25

We are given that the owner bakes 200 pies each day at a cost of $2.50 each.

So, Cost per day =[tex]200 \times 2.50 =500[/tex]

Probability     No. of pies          Cost

0.5                        100               500

0.25                      150               500

0.25                      200              500

Now we are given that  she sells the pies for $3 each

So, SP of 100 pies =[tex]3 \times 100 = 300[/tex]

SP of 150 pies = [tex]150 \times 3 = 450[/tex]

SP of 200 pies = [tex]200 \times 3 = 600[/tex]

Probability     No. of pies          Cost       Revenue      Profit

0.5                        100               500           300            -200

0.25                      150               500           450            -50

0.25                      200              500            600           100

Answer:

4.6 or if you rounded it would be 5

Answer:

8

Step-by-step explanation:

First, we have to simplify the equation. A negative term multiplied by a minus sign will ALWAYS be positive.

-(-14) = 14

Then, we will evaluate the expression.

-6+14 = 8

If it helps, you can rearrange the equation.

14-6 = 8.

Answer: It's between 10 and 11

It's closer to 11 than it is to 10.

This is because [tex]\sqrt{113} \approx 10.63[/tex] after using a calculator.

You could also look at the list of perfect squares

{1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144,...}

The terms in bold are where 113 fits in between. So we can say,

[tex]100 < 113 < 121\\\\\sqrt{100} < \sqrt{113} < \sqrt{121}\\\\10 < \sqrt{113} < 11\\\\[/tex]

Answer:

[tex]P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}[/tex]

Step-by-step explanation:

Given

[tex]Total\ Employees = 17[/tex]

[tex]To\ Select = 3[/tex]

Required

Determine the probability of selecting You, Anna and Kevin

Assuming the selection process is fair;

Each employee has a probability of;

[tex]Probability = \frac{1}{17}[/tex]

So:

[tex]P(You\ n\ Anna\ n\ Kevin) = P(You) * P(Anna) * P(Kevin)[/tex]

[tex]P(You\ n\ Anna\ n\ Kevin) = \frac{1}{17} * \frac{1}{17} * \frac{1}{17}[/tex]

[tex]P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}[/tex]

The  probability that you, Anna, and Kevin are chosen is [tex]1\div 4913[/tex]

Since there is three employees in your office to attend a conference in Jamaica. And, Because all 17 of you want to go, he decides that the only fair way is to draw names out of a hat.

So, here the probability should be

[tex]= (1\div 17)^3\\\\= 1\div 4913[/tex]

Answer:

Only statements A & C are true.

Step-by-step explanation:

Solving this problem entails of substituting the values provided in each option into the given equation, in order to determine which are true. Take a look at how each is solved.

Option One

        Given: y = 2,182; x = 240

        y = 9x + 22

        2,182 = 9(240) + 22

       2,182 = 9(240) + 22

       2,182 = 2,160 + 22

        2,182 = 2,160 + 22

        2,182 = 2,182

        2,182 = 2,182 true

Option Two

        Given: y = 2,527; x = 280

        y = 9x + 22

        2,527 = 9(280) + 22

        2,527 = 9(280) + 22

        2,527 = 2,520 + 22

        2,527 = 2,520 + 22

        2,527 = 2,542

        2,527 = 2,542 not true

Option Three

        Given: y = 3,838; x = 424

        y = 9x + 22

       3,838 = 9(424) + 22

       3,838 = 9(424) + 22

       3,838 = 3,816 + 22

       3,838 = 3,816 + 22

       3,838 = 3,838

       3,838 = 3,838 true

Option Four

        Given: y = 4,322; x = 480

        y = 9x + 22

        4,322 = 9(480) + 22

        4,322 = 9(480) + 22

        4,322 = 4,320 + 22

        4,322 = 4,320 + 22

        4,322 = 4,342

        4,322 = 4,342 not true

Option Five

        Given: y = 4,980; x = 552

        y = 9x + 22

        4,980 = 9(552) + 22

        4,980 = 9(552) + 22

        4,980 = 4,968 + 22

        4,980 = 4,968 + 22

        4,980 = 4,990

        4,980 = 4,980 not true

This proves that only options 1 & 5 are correct.

Answer:

MOM

Step-by-step explanation:

The solution to the equation are y = 26 - 13x and x = 2 - y/13

The equation is given as:

13x + y = 26

To do this, we solve for x and we solve for y

We have:

13x + y = 26

Subtract 13x from both sides

y = 26 - 13x

Also, we have:

13x + y = 26

Subtract y from both sides

13x = 26 - y

Divide through by 13

x = 2 - y/13

Hence, the solution to the equation are y = 26 - 13x and x = 2 - y/13
