Answer:

-515

Step-by-step explanation:

In this example the first value is −15 and every value afterwards is 20 less.

After substituting these values to above formula, we obtain:

All we have to do is add 25 twenties or 25 x 20 = 500 and -15 - 500 = -515

The required 28 th term of the given arithmetic sequence is given as -555.

Arithmetic progression is the series of numbers that have common differences between adjacent values that are equal.

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
Given sequence,
-15,-35,-55,-75,...

From the above sequence,
The first term, a = -15
Common difference d = -35 +15 = -20

nth term is given as,
nth = a + (n - 1)d
nth = -15 -20 (n - 1)

Now put n = 28
28th = -15 -20(28 - 1)
       = -15 - 540
       = -555

Thus, the required 28 th term of the given arithmetic sequence is given as -555.

Step-by-step explanation:

Answer:

After 3 years it will be $9,400

Step-by-step explanation:

First multiply 23,500 by .20 and get 4700. Now multiply by 3 which is 3 years and it equals 14,100. Now subtract from 23,500-14,100 and get 9,400.

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.

Step-by-step explanation:

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:

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

To evaluate 5log5 63, use the property of logarithms that states loga b = logc b / logc a. Using a calculator, we find that 5log5 63 ≈ 2.57.

To evaluate 5log5 63, we use the property of logarithms which states that loga b = logc b / logc a. In this case, a = 5 and b = 63. So, 5log5 63 = log10 63 / log10 5. Using a calculator, we find that log10 63 ≈ 1.798 and log10 5 ≈ 0.699. Therefore, 5log5 63 ≈ 1.798 / 0.699 ≈ 2.57. So the correct answer is not listed among the options provided.

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.

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.

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.

In mathematics, the expression a⁵ × (a³)² simplifies to a¹¹ by following rules of exponents. Simplify within parentheses first to get a⁶, then combine to get a¹¹.

The term a⁵ × (a³)² represents the product of a number 'a' raised to the power of 5 and 'a' raised to the power of 3, squared. To simplify an expression like this, use the rule of exponents that states: aⁿ * aᵐ = aⁿ+ᵐ and for (a^n)^m, this equates as a^(n*m).

Start by simplifying the exponent in the parentheses first: (a³)² = a^(3*2) = a⁶. Then you're left with a⁵ × a⁶. Using the rules of exponents again, you add the powers together: a^(5+6) which simplifies to a¹¹.

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: 16,000,000

Step-by-step explanation:

Answer:

16,000,000 beans total.

Step-by-step explanation:

Start with what you're given. Each bag has 20,000 beans, right?

There are, for some unknown, ungodly reason, 800 bags. Okay, great. It's a lot of bags of beans and I don't understand why there needs to be so much, but this is math. Most "related to real-world" problems in math don't make logical sense.

So we've established how many bags there are, and how many beans each bag has. You'll need to multiply those two together to get how many beans there are total. However, 20,000 times 800 is a very ridiculously large number and takes a lot of time. So, how do we make it easier to understand?

We focus on the most important parts.

800 and 20,000 are large numbers, but simple as well. The only digits are 8 and 2, followed by zeroes. Just multiply 8 times 2, and you get 16. Now add the number of zeroes from 800, and the number of zeroes from 20,000, and you'll end up with 6 zeroes.

So your answer should be 16 followed by 6 zeroes, or 16,000,000.

That's a lot of beans.
