The Wall Street Journal reporter the biggest music comeback in 2014 was vinyl records. Nearly 8 million vinyl were sold in 2014, mostly to younger markets. If there were 15 vinyl record factories pressing records in the United States in 2014, and only 2/3 remain operational in 2015, how many factories closed down?

Answers

Answer:

5 factories closed

Step-by-step explanation:

In 2014 there were 15 operating factories.

We know that of those 15 factories only 2/3 remain operative.

If only 2/3 remain operational this means that 1/3 of them closed.

To calculate the number of factories that closed we must multiply the initial number of operative factories by 1/3.

This is:

[tex]15 * \frac{1}{3} = \frac{15}{3} = 5[/tex].

Answers

Answer:

29/40

Step-by-step explanation:

A basket contains 14 white eggs, 15 brown eggs, and 11 lemons. The exact probability that Taylor picks an egg from the basket is;

(14+15)/(14+15+11) = 29/40

Answer:

The exact probability that Taylor picks an egg from the basket is 0.725

Step-by-step explanation:

A basket contains 14 white eggs, 15 brown eggs and 11 lemons.

Total number of items in the basket [tex]=14+15+11= 40[/tex]

Total number of eggs in the basket [tex]=14+15= 29[/tex]

Taylor picks one item at random from the basket.

So, the probability that Taylor picks an egg [tex]=\frac{total\ number\ of\ eggs}{total\ number\ of\ items}=\frac{29}{40}=0.725[/tex]

The sector of a circle with a 12-inch radius has a central angle measure of 60

What is the exact area of the sector in terms of pi

Answers

Answer:

24 π square inches

Step-by-step explanation:

The area of a circule is give by the formula A = π r²

Since we have a angle of 60 degrees, that represent 1/6th of the whole area (60 / 360 degrees).

A circle = π * 12² = 144 π square inches

Area of the portion representing 60 degrees of the circle, can easily be calculated with a cross-multiplication:

[tex]\frac{x}{144\pi } = \frac{60}{360}[/tex]

x = 144 π / 6 = 24 π square inches

B.373,709.25
C.2461.55
D.2273.13

Answers

Answer:

Option D. $2273.13

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=7\ years\\ P=\$1,685\\ r=0.043\\n=4[/tex]  

substitute in the formula above  

[tex]A=\$1,685 (1+\frac{0.043}{4})^{4*7}=\$2,273.13[/tex]  

 

The sum of four consecutive odd numbers is 40 what is the greatest of the four numbers

Answers

Answer:

13

Step-by-step explanation:

First find the average the numbers (40 / 4 = 10)

2 are more and 2 are less

7, 9, 11, 13

An odd number can be written as 2n+1, where n is an integer. Four consecutive odd numbers can be written as 2n-3, 2n - 1, 2n + 1 and 2n + 3. Adding these together gives you 8n, which we are told is 40. So n is 5 and the four consecutive odd numbers are 7, 9, 11 and 13.

what makes n true 1/2 (n+4)=6

Answers

Answer: N=8

Step-by-step explanation: So 1/2*4=2 then you know that you need 4 to get to six because you already have two. Then 8/2=4 so N=8.

1/2(8+4)=6

4+2=6

6=6

Hope this helped!!!!!

Final answer:

To find the value of n that satisfies the equation 1/2 (n+4)=6, multiply both sides by 2 and subtract 4 from both sides to get n=8.

Explanation:

The student's question asks for the solution to the algebraic equation: 1/2 (n+4)=6. To solve for n, follow these steps:

Multiply both sides of the equation by 2 to get rid of the fraction: n + 4 = 12.Subtract 4 from both sides to isolate n: n = 12 - 4.Simplify the equation to find the value of n: n = 8.

Therefore, the value of n that makes the equation true is 8.

2. What is the external probability of rolling a 4


3 what is the external probability of getting at least one tail

Answers

Answer:

2. 1- Experimental probability of rolling a 4 = 40%

3. 2- Theoretical probability is 3%  greater than experimental probability.

Step-by-step explanation:

Experimental probability of rolling a 4 = 100 × [tex]\frac{8}{20}[/tex]

                                                                  = 100 × 0.4

                                                                  = 40%

Experimental probability of getting at least one tail  = [tex]\frac{72}{100}[/tex]

                                                                                    = 0.72

Theoretical probability of getting at least one tail  = [tex]\frac{3}{4}[/tex]

                                                                                  = 0.75

Theoretical probability is 3%  greater than experimental probability.

Two architectural models are pyramids with bases of equal area. The smaller model has a height of 10 centimeters, and the larger model has a height of 30 centimeters. How many times greater than the smaller model is the larger model’s volume?

Answers

Answer:

The larger model’s volume is 3 times greater than the volume of the smaller model

Step-by-step explanation:

we know that

The volume of a pyramid is equal to

[tex]V=\frac{1}{3}Bh[/tex]

where

B is the area of the base of pyramid

h is the height of the pyramid

Find the volume of the smaller model

we have

[tex]h=10\ cm[/tex]

substitute

[tex]V=\frac{1}{3}B(10)[/tex]

[tex]V=\frac{10}{3}B\ cm^{3}[/tex]

Find the volume of the larger model

we have

[tex]h=30\ cm[/tex]

substitute

[tex]V=\frac{1}{3}B(30)[/tex]

[tex]V=\frac{30}{3}B=10B\ cm^{3}[/tex]

To find how many times greater than the smaller model is the larger model’s volume, divide the volume of the larger model by the volume of the smaller model

so

[tex]10B/(\frac{10}{3}B)=3[/tex]

The larger model’s volume is 3 times greater than the volume of the smaller model

There is a 90% chance of rain tomorrow and a 30% chance that the baseball game is postpone. What is the probability it will rain tomorrow and the baseball game is postponed.

Answers

Hello! :)

The answer is probably from changing first to decimals by dividing by 100: 90 and 30 become .9 and .3.

Then, multiply the two: .9 x .3 = .27

Finally, you multiply .27 by 100 = 27

Add the percentage sign: 27%

So there is a 27% chance that it will rain and the baseball game is postponed.

Very unlikely, I know. ;D

The probability it will rain tomorrow and the baseball game is postponed is 0.93 .

What is probability ?

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

According to classical definition of probability, a random experiment consists of a set of possible outcomes and each set of possible outcomes is equally likely to occur in the course of the event.

How to calculate the given probability ?

It is given that there is a 90% chance of rain tomorrow and a 30% chance that the baseball game is postpone.

Let A be the probability that there is a chance of rain tomorrow and B be the probability that the baseball game is postpone.

P(A) = 90% = 0.9 and P(B) = 30% = 0.3 and P(A∩B) = (0.9*0.3) = 0.27 .

The probability it will rain tomorrow and the baseball game is postponed is given by P(A∪B) .

By formula,

⇒ P(A∪B) = P(A) + P(B) - P(A∩B)

⇒ P(A∪B) = 0.9 + 0.3 - 0.27

∴  P(A∪B) = 0.93 .

Therefore, the probability it will rain tomorrow and the baseball game is postponed is 0.93 .

A fraction reduces to 36. If its denominator is 6x^5, what it's its numerator?

Answers

Final answer:

To determine the numerator of a fraction that simplifies to 36 with a denominator of 6x^5, you solve the equation Numerator/6x^5 = 36 by multiplying both sides by 6x^5, resulting in a numerator of 216x^5.

Explanation:

To find the numerator of a fraction that reduces to 36 with a denominator of 6x^5, we set up an equation to represent the fraction in its simplest form.

We know that when we divide the numerator by the denominator, the result is 36. Therefore, the equation to solve is Numerator/6x^5 = 36.

Multiplying both sides of the equation by 6x^5 will isolate the numerator on one side.

The calculation becomes:

Numerator = 36 × 6x^5

Next, we carry out the multiplication to find:

Numerator = 216x^5

This means that the numerator of the original fraction is 216x^5.

Use the perfect square method
(3x + 3)^2 = 36

Answers

Factor out the common term; 3

(3(x + 1))^2 = 36

Use the Multiplication Distributive Property; (xy)^a = x^ay^a

3^2(x + 1)^2 = 36

Simplify 3^2 to 9

9(x + 1)^2 = 36

Divide both sides by 9

(x + 1)^2 = 36/9

Simplify 36/9 to 4

(x + 1)^2 = 4

Take the square root of both sides

x + 1 = √4

Since 2 * 2 = 4, the square root of 2 is 2

x + 1 = 2

Break down the problem into these 2 equations

x + 1 = 2

x + 1 = -2

Solve the first equation; x + 1 = 2

x = 1

Solve the second equation; x + 1 = -2

x = -3

Collect all solutions;

x = 1, -3

Find the equation of the line that is perpendicular to y=-2/3x and contain the point (4,-8)

Answers

Answer:

y = 3/2x - 14.

Step-by-step explanation:

The slope of the perpendicular line  is - 1 / -2/3

= 3/2.

Using the point slope form y-y1 = m(x-x1):

y - (-8) = 3/2(x - 4)

y + 8 = 3/2x - 6

y = 3/2x - 14.

Answer:

y = [tex]\frac{3}{2}[/tex] x - 14

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{2}{3}[/tex] x ← is in this form

with slope m = - [tex]\frac{2}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{3} }[/tex] = [tex]\frac{3}{2}[/tex], hence

y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation of the perpendicular line

To find c substitute (4, - 8) into the partial equation

- 8 = 6 + c ⇒ c = - 8 - 6 = - 14, so

y = [tex]\frac{3}{2}[/tex] x - 14 ← equation of perpendicular line
