The head of operations for a movie studio wants to determine which of two new scripts they should select for their next major production. (Due to budgeting constraints, only one new picture can be undertaken at this time.) She feels that script 1 has a 70 percent chance of earning about $10,000,000 over the long run, but a 30 percent chance of losing $2,000,000. If this movie is successful, then a sequel will be produced, with an 80 percent chance of earning $5,000,000, but a 20 percent chance of losing $1,000,000. On the other hand, she feels that script 2 has a 60 percent chance of earning $12,000,000, but a 40 percent chance of losing $3,000,000. If successful, its sequel would have a 50 percent chance of earning $8,000,000, but a 50 percent chance of losing $4,000,000. Of course, in either case, if the original movie were a flop, then no sequel would be produced. What is the probability that script 1 will be a success, but its sequel will not?

Answers

Answer: $9,000,000

Step-by-step explanation:

Probability is simply defined as the chance or likelihood that an event is going to happen or occur.

The probability that script 1 will be a success, but its sequel will not is the success of script 1 added to the failure of its sequel.

The total payoff will simply be the sum of the individual layoffs of both the success and the failure. This will be:

= $10,000,000 + (- $1,000,000)

= $10,000,000 - $1,000,000

= $9,000,000

Using conditional probability, it is found that there is a 0.14 = 14% probability that script 1 will be a success, but its sequel will not.

Conditional Probability

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.

In this question:

Event A: Script 1 is a sequel.Event B: It's sequel is not.

Sequel 1 has a 70% probability of being a success, hence [tex]P(A) = 0.7[/tex].If it is a success, the sequel has a 80% probability of being a success, hence a 20% probability of being a failure, thus [tex]P(B|A) = 0.2[/tex]

Then:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(A)P(B|A)[/tex]

[tex]P(A \cap B) = 0.7(0.2)[/tex]

[tex]P(A \cap B) = 0.14[/tex]

0.14 = 14% probability that script 1 will be a success, but its sequel will not.

An hour is 60 minutes.

Multiply the amount of tasks to the amount of times 20 goes into 60 (60/20).

Step-by-step explanation:

If the number is multiplied by 4 it square root is effectively doubled.

Example: if you take the square root of 64, its 8.

to double the square root, you multiply 64 by 4---> 256.

And the square root of 256, is 16, double that of the square root of 64.

Solve for x. Show steps.

5x + 8 = 7x + 2

Answers

Combine the same numbers and do the opposite of either subtraction or addition.

Then, multiply or divide with the coefficient.

Answer:

see below

Step-by-step explanation:

⇒  7x - 17 = 4x + 1

combine like terms

7x - 4x = 1 + 17

3x = 18

x = 18/3

x = 6

⇒  -x + 5 = x - 11

combine like terms

- x - x = - 11 - 5

-2x = -16

x = 16 / 2

x = 8

⇒  5x + 8 = 7x + 2

combine like terms

5x - 7x = 2 - 8

- 2x = - 6

x = 6 / 2

x = 3

How to express a vector as a product of its length and direction?

Answers

Answer:

So the way to  express a vector( [tex]v =  2i - 2j - 2k[/tex]) as a product of its length and direction is

        [tex]v  =    |v| u =  \sqrt{12} (\frac{2}{ \sqrt{12} } , -\frac{2}{ \sqrt{12} }, - \frac{2}{ \sqrt{12} })[/tex]

 

Step-by-step explanation:

Generally a vector  is  expressed as a product of its length and direction using the formula below  

           [tex]v  =  |v|\cdot u[/tex]

Here v is the vector

        |v| is its magnitude (length)

         u is its unit vector (direction)

Now let take an example

Let  

     [tex]v =  2i - 2j - 2k[/tex]

The magnitude is mathematically evaluated as

          [tex]|v| =  \sqrt{ 2^2  + (-2)^2 +  (-2)^2 }[/tex]

         [tex]|v| =  \sqrt{12}[/tex]

The unit vector is mathematically represented as

        [tex]u  =  \frac{v}{|v|}[/tex]

        [tex]u  =  \frac{ <2 , -2 , -2>}{\sqrt{12} }[/tex]

    [tex]u =  \frac{2}{ \sqrt{12} } , -\frac{2}{ \sqrt{12} }, - \frac{2}{ \sqrt{12} }[/tex]

So

    [tex]v  =    |v| u =  \sqrt{12} (\frac{2}{ \sqrt{12} } , -\frac{2}{ \sqrt{12} }, - \frac{2}{ \sqrt{12} })[/tex]

Korey is planning to open a comic book store. His store will cost $12,500 to open and will come with a $8,000 total annual operational cost. If his store makes $12,000 in profit during the first year, and profits increase by 6% each year from then, how long will it take for Korey to see an overall profit in his business (where total profits exceed total expenses)? a. Korey will see an overall profit in his first year of business. b. Korey will see an overall profit in his second year of business. c. Korey will see an overall profit in his third year of business. d. Korey will see an overall profit in his fourth year of business.

Answers

Answer:

c. Korey will see an overall profit in his third year of business

Step-by-step explanation:

His cost for first year

= 12500+8000

=$ 20500

Profit first year= $12000

Net Profit first year= -$8500

Second year cost= $8000

Profit second year

= 12000+12000(0.06)

= 12000+720

=$ 12720

Net profit second year = -8500+12720-8000

= -3780

Third year

Cost = $8000

Profit= 12720+12720(0.06)

Profit=$13483.2

Net profit= 13483.2-8000-3780

Net profit= $1703.2

Korey will see an overall profit in his third year of business.

What is profit?

The amount of money earned by any seller on the cost price is called the yield.

His cost for the first year

=  12500 + 8000

=$ 20500

Profit first year= $12000

Net Profit first year= -$8500

Second year cost= $8000

Profit second year

= 12000+12000(0.06)

= 12000+720

=$ 12720

Net profit second year = -8500+12720-8000

= -3780

Profit for Third-year

Cost = $8000

Profit= 12720+12720(0.06)

Profit=$13483.2

Net profit= 13483.2-8000-3780

Net profit= $1703.2

Therefore Korey will see an overall profit in his third year of business.

The volume of a volleyball is about 288 cubic inches. what is the radius of the volleyball, to the nearest tenth of an inch? use 3.14 for π.
[tex]r = \sqrt{ \frac{3v}{4\pi} } [/tex]

Answers

Answer:

The radius of the volleyball is 8.3 inches

Step-by-step explanation:

Given

[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]

[tex]v = 288[/tex]

Required

Determine the value of r

To do this, we simply substitute 288 for v and 3.14 for π in the given equation.

This gives

[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]

[tex]r = \sqrt{\frac{3 * 288}{4 * 3.14}}[/tex]

[tex]r = \sqrt{\frac{864}{12.56}}[/tex]

[tex]r = \sqrt{68.7898089172}[/tex]

[tex]r = 8.29396219651[/tex]

The area of a rectangular wall of a barn is 270 square feet. It’s length is 12 feet longer than twice it’s width. Find the length and width of the wall of the barn.

Answers

Answer: 258

Step-by-step explanation: 270-12=w

The width of the wall is 9 feet and length is 30 feet.

What is perimeter of a rectangle ?

The perimeter of a rectangle is the sum of all the sides.

According to the given question the area of a rectangular wall of a barn is 270 square feet. It’s length is 12 feet longer than twice it’s width.

Assuming the width of the rectangular wall to be x feet.

∴ From the given data length is 2x + 12 feet.

We know area of a rectangle is product of it's length and width.

So, { x × ( 2x + 12 ) } = 270.

2x² + 12x = 270.

2x² + 12x - 270 = 0

x² + 6x - 135 = 0

x² + 15x - 9x - 135 = 0

x(x + 15) - 9(x + 15) = 0

( x + 15 ) = 0 OR ( x+ 9 ) = 0

∴ x = -15 OR x = 9.          ( we know length can note be negative )

So, Width of the rectangle is 9 feet and length is 30 feet.

Answers

Answer: 9.42 cm.

Step-by-step explanation:

Length of arc is given by :-

[tex]l= \dfrac{x}{360}\times2\pi r[/tex] , where r= radius and x= central angle subtended by arc.

As per given , we have

[tex]x=30^{\circ}\\\\ r=18\ cm[/tex]

Then, the length of arc will be :

[tex]l=\dfrac{30}{360}\times2(3.14)(18)\\\\=\dfrac{1}{12}\times113.04\\\\=9.42\ cm[/tex]

Hence, the length of arc is 9.42 cm.

The length of an arc of a circle with radius 18cm is; L = 9.426cm

Length of an arc

The length of an arc can be evaluated using the formula;

L = (∆/360) × 2πr

Hence, the length of the given arc is;

L = (30/360) × 2 × 3.142 × 18cm

L = 9.426cm
