Answer:

Selling price = $28

Step-by-step explanation:

Cost price = $20

Selling price = ?

Percent markup = 40%.

Percentage markup is the difference between a products selling price and cost as a percentage to the cost.

% mark up = (selling price - cost price) / (cost price) * 100

[(Selling price - 20) / 20 ] * 100 = 40

40 / 100 = (selling price - 20) / 20

0.4 * 20 = selling price - 20

8 = selling price - 20

Selling price = $(8 + 20)

Selling price = $28.

The selling price was $28

Answer: The selling price is $28

Step-by-step explanation: If the CD set was bought at the cost of $20 and sold at a selling price of $20 plus 40% (or 0.4), then we should start by calculating the value of 40% of the cost price, which would then be added to the cost price to arrive at the selling price.

The calculation is as follows;

Mark up = 20 x 0.4

Mark up = 8

Selling price = Cost price + Mark up

Selling price = 20 + 8

Selling price = 28

Therefore the selling price is $28

Step-by-step explanation:

The price of computer  = 850

The price of computer after 2 years = 306

By compound depreciation,

 [tex]Pn = P (1 - \frac{R}{100} ) ^ T[/tex]   ... (i)

where Pn = 306

P = 850

R = rate of interest to be calculated

T = 2( number of years)

substituting the values in equation (1), we get

[tex]306 = 850 (1 - \frac{R}{100} ) ^ 2[/tex]

0.6 = 1 - [tex]\frac{R}{100}[/tex]

R = 40%

The worth after 5 years =

[tex]Pn = 850 (1 - \frac{40}{100} ) ^ 5[/tex]

Pn = 850 (0.077)

= $66.096 = $ 66

The computer be worth after 5 years = $ 66 (option B)

After 5 years, the computer will be worth is $66 (B).

To solve this problem, we'll use the formula for exponential decay, where the rate of decrease is proportional to the value of the computer at that time.

The formula for exponential decay is:

[tex]\[ V(t) = V_0 \times e^{-kt} \][/tex]

Where:

- [tex]\( V(t) \)[/tex] is the value of the computer at time [tex]\( t \)[/tex],

- [tex]\( V_0 \)[/tex] is the initial value of the computer,

- [tex]\( k \)[/tex] is the decay constant, and

- [tex]\( t \)[/tex] is the time in years.

Given:

- [tex]\( V_0 = $850 \)[/tex]

- [tex]\( V(2) = $306 \)[/tex]

We need to find the value of [tex]\( k \)[/tex] using the given information.

[tex]\[ 306 = 850 \times e^{-2k} \][/tex]

Divide both sides by 850:

[tex]\[ \frac{306}{850} = e^{-2k} \][/tex]

Taking the natural logarithm of both sides:

[tex]\[ \ln\left(\frac{306}{850}\right) = -2k \][/tex]

Solve for [tex]\( k \)[/tex]:

[tex]\[ k = -\frac{\ln\left(\frac{306}{850}\right)}{2} \][/tex]

Now that we have [tex]\( k \)[/tex], we can find [tex]\( V(5) \)[/tex]:

[tex]\[ V(5) = 850 \times e^{-5k} \][/tex]

Substitute the value of [tex]\( k \)[/tex] and compute:

[tex]\[ V(5) = 850 \times e^{-5 \times \left(-\frac{\ln\left(\frac{306}{850}\right)}{2}\right)} \][/tex]

[tex]\[ V(5) = 850 \times e^{\frac{5\ln\left(\frac{306}{850}\right)}{2}} \][/tex]

[tex]\[ V(5) = 850 \times \left(\frac{306}{850}\right)^{\frac{5}{2}} \][/tex]

V(5) = 66.61

Therefore, after 5 years, the computer will be worth is  $66.

Answer: 90% decrease

Step-by-step explanation: First determine whether the number is increasing or decreasing. Since it changes from 2,000 to 200, it's going down so it's decreasing.

Now to find the percent decrease, we divide the

amount of change by the original number.

The amount of change is the difference between the two numbers

which in this case is 2,000 - 200 and the original number is 2,000.

[tex]So[/tex] [tex]we[/tex] [tex]have[/tex] [tex]\frac{2,000 - 200}{2,000}[/tex].

2,000 - 200 is 1,800.

So we're left with 1,800/2,000 and dividing

2,000 into 1,800 gives us 0.9.

Remember however that our problem is

asking for a percent, not a decimal.

So we need to write 0.9 as a percent and we can do

that by multiplying it by 100 and adding the percent sign.

So 0.9 becomes 90%.

So when a number changes from 2,000 to 200,

it has decreased by 90%.

This interval (0.175, 0.225) represents the range of values that the true proportion of U.S. adults that can answer the question of 'which gas makes up the most of the atmosphere?' correctly, can take on, with a confidence level of 95%.

Step-by-step explanation:

Confidence Interval is an interval obtaimed from sample data, for the population proportion. It is an interval of range of values where the true population proportion can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample proportion) ± (Margin of error)

Margin of Error is the width of the confidence interval about the mean (sample proportion).

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error of the sample proportion)

Critical value is obtained from the z-tables or the t-tables depending on which information is available. For distributions where information on the population standard deviation is known or it isn't know but the sample size is large enough for the sample standard deviation can approximate the population standard deviation, the z-tables is used and for those distributions whose population standard deviation information is not known, and sample size isn't large enough, the critical value is read off the t-tables.

The critical value depends on the confidence level for both the z-tables and the t-tables critical value.

The interval obtained now represents the region of values where the true population proportion can exist within, at a certain level.of confidence.

Step-by-step explanation:

As we can see, the number of hours in plot A goes from 3 to 10 with a gap in 8 and 9, while in plot B, goes from 3 to 7, with no gaps.

Let's calculate the mean and media for both plots:

Plot A:

Mean = (3 + 2 * 4 + 2 * 5 + 2 * 6 + 2 * 7 + 10)/10

Mean = 57/10 = 5.7

Median = 5 + 6/2 = 11/2 = 5.5

Plot B:

Mean = (3 + 2 * 4 + 3 * 5 + 3 * 6 + 7)/10

Mean = 51/10 = 5.1

Median = 5 + 5/2 = 10/2 = 5

Mean comparison: 5.7 > 5.1

Median comparison: 5.5 > 5

In consequence, the correct answer is A. Both the mean and median are greater for Plot A than for Plot B.

Answer:

1 Pair of Jeans cost $35

1 Shirt costs $21

Step-by-step explanation:

$231 - $133= $98

$133 - $98 = $35 --- Pair of Jeans

$35 × 2 = $70

$133 - $70 = $63

$63/3 = $21 --- Shirt

The cost of each pair of jeans and each shirt can be found by setting up and solving simultaneous equations. The cost of each pair of jeans is $27, and the cost of each shirt is $25.

This problem can be solved using the method of simultaneous equations. We'll first form two equations based on the given information. Let's assume the cost of a pair of jeans is 'x' dollars and the cost of a shirt is 'y' dollars.

Let's simplify the second equation by dividing it by 3, which makes it x + 2y = 77. Subtract this from the first equation to eliminate 'x'. You're left with y = 25. Substitute y = 25 into the simplified second equation to get x = 27. So each pair of jeans costs $27 and each shirt costs $25.

Its True a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.

Given that,
A circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle. Whether it's true or false is to be justified in a statement.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.

Here, the distance of the point on the circumference of the circle has a fixed distance from the center.

Thus, it's true a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.

Answer:

B. a = 15, b = 7, c = 5, d = 10, e = 12  

Step-by-step explanation:

The values that complete the table are a = 15, b = 7, c = 5, d = 10, and e = 12. Therefore, option B is correct.

Given that there are 32 campers in total, and 22 of them can swim, and 20 of them play softball. We also know that 5 campers do not play softball or swim.

We are asked to complete the table, which consists of rows and columns, with the third row and third column showing the totals.

Let's start with the third row. According to the table, the total number of campers who can swim and play softball is a + b. And since we know that 20 campers play softball, we can write:

a + b = 20

Moving on to the third column, the total number of campers who can swim is a + c. We also know that 22 campers can swim, so we can write:

a + c = 22

Now we have two equations and two unknowns, namely a and c. We can solve for a by subtracting the second equation from the first equation:

(a + b) - (a + c) = 20 - 22

Simplifying this expression, we get:

b - c = -2

We also know that 5 campers do not play softball or swim. So the total number of campers who do not play softball is:

32 - 20 = 12

And since 5 campers do not play softball or swim, the remaining 7 campers do not play softball but can swim. Therefore, we can write:

c + d = 7

Substituting the value of d from equation (1), we get:

c + 10 = 7

Solving for c, we get:

c = 5

Now that we know the value of c, we can solve for a using equation (2):

a + c = 22

Substituting the value of c, we get:

a + 5 = 22

Solving for a, we get:

a = 15

Using the value of a, we can solve for b using equation (3):

a + b = 20

Substituting the value of a, we get:

15 + b = 20

Solving for b, we get:

b = 5

Finally, we can solve for e using equation (4):

20 + e = 32

Solving for e, we get:

e = 12

Therefore, the values that complete the table are a = 15, b = 7, c = 5, d = 10, and e = 12.

Step-by-step explanation:

Answer:

14(1.56) + 18h = 32(1.515)

21.84 + 18h = 48.48

18h = 26.64

h = 1.48 meters

The mean height of the girls in the class is 1.48 meters.

To calculate the mean height of the girls in the class, we will use the information provided about the mean heights of the boys and the entire class. Since we know the mean height of the 14 boys is 1.56 meters, we can find the total height of all boys by multiplying 1.56 by 14, which equals 21.84 meters. For the entire class of 32 students, the mean height is 1.515 meters. Multiplying 1.515 by 32 gives us the total height for the entire class, which is 48.48 meters. To find the total height of the girls, we subtract the total height of the boys from the total height of the class: 48.48 meters - 21.84 meters = 26.64 meters. Since there are 32 students in total and 14 boys, there must be 18 girls. To find the mean height of the girls, divide the total height of the girls by the number of girls: 26.64 meters / 18 girls = 1.48 meters.
