Given the sum of the sequence and the first term, we rearrange the formula for the sum to solve for 'd', the common difference. This will allow us to calculate the term at any given point in the arithmetic sequence.

In an arithmetic sequence, the nth term can be represented by the formula a + (n-1)d where 'a' is the first term, 'n' is the number of terms and 'd' is the common difference between the terms.

The sum, 's', of the first 'n' terms in an arithmetic sequence is given by the formula s = n/2 * (2a + (n - 1)d).

Given the sum, 's', and the first term in the sequence, 'a', we can rearrange the sum formula to find 'd', the common difference, which will then allow us to find any term in the sequence.

We have s16 = -288 and a1 = -21. So, our problem reduces to solve for 'd' in s = n/2 * (2a + (n - 1)d) The solution with most relevance to the student's question will be the calculated 'd' value.

The cost function is an illustration of linear functions

From the question, we have:

[tex]G = 4.50[/tex] --- cost per game

[tex]R = 3.75[/tex] --- cost per shoe rent

Since the cost is a function of number of games, it means that;

The cost of shoe rent is a fixed cost

Let x represents the number of games.

So, the cost function is:

[tex]C(x) = R + G \times x[/tex]

This gives

[tex]C(x) = 3.75 + 4.50 \times x[/tex]

[tex]C(x) = 3.75 + 4.50x[/tex]

Substitute 3 for x; to evaluate the function for 3 games

[tex]C(3) = 3.75 + 4.50 \times 3[/tex]

[tex]C(3) = 3.75 + 13.50[/tex]

[tex]C(3) = 17.25[/tex]

Hence, the cost for three games is $17.25

The equilibrium rate of return is 8.3%.

The equilibrium rate of return of a security is the sum of the real risk-free rate, the inflation risk premium, the default risk premium, the liquidity risk premium, and the maturity risk premium.

In this case, the equilibrium rate of return is:

3.5% + 1.75% + 2% + 0.25% + 0.85% = 8.3%

So the answer is 8.3%.

Here is a breakdown of the calculation:

The real risk-free rate is the rate of return that investors would expect to earn on an investment with no risk of default or inflation.

The inflation risk premium is the additional return that investors demand to compensate them for the risk of inflation.

The default risk premium is the additional return that investors demand to compensate them for the risk of default on a security.

The liquidity risk premium is the additional return that investors demand to compensate them for the difficulty of selling a security quickly and easily.

The maturity risk premium is the additional return that investors demand to compensate them for the risk that the value of a security will decline as it approaches maturity.

Step-by-step explanation:

Answer:

Approximately 391 minutes taken by 20 people to paint 20 walls.                    

Step-by-step explanation:

Given : It takes 48 minutes for 7 people to paint 7 walls.

To find : How many minutes does it take 20 people to paint 20 walls?

Solution :

7 people to paint 7 walls in 48 minutes.

So, 1 people to paint 7 walls in [tex]\frac{48}{7}[/tex] minutes.

and 1 people to paint 1 walls in [tex]\frac{48}{7\times 7}[/tex] minutes.

Now, We have to find minutes does it take 20 people to paint 20 walls.

20 walls will be painted in [tex]\frac{48\times 20}{7\times 7}[/tex] minutes.

20 people to paint 20 walls in [tex]\frac{48\times 20\times 20}{7\times 7}[/tex] minutes.

i.e. [tex]\frac{48\times 20\times 20}{7\times 7}=\frac{19200}{49}=391.83[/tex]

Therefore, Approximately 391 minutes taken by 20 people to paint 20 walls.

The numbers are consecutive, meaning they are in arithmetic progression.

Sum of Arithmetic Progression = (n/2)[2a + (n- 1)d]

Where, n = total number of numbers and d = common difference between two successive numbers

Therefore n = 4 and d = 1 ( as the numbers are consecutive )

now (4/2)(2a + (4 - 1)1) = 2

i.e. 2(2a + 3) = 2

i.e. 4a + 6 = 2

i.e. 4a = - 4

i.e. a = - 1

Therefore nos are -1, -1+1 , -1+1+1 , -1+1+1+1

i.e. -1, 0 , 1 , 2

Hope this helps..!!

When making enough BLT sandwiches to use 2 full heads of lettuce, Omar will be using 2.5 pounds of bacon and will end up making a total of 40 BLT sandwiches.

The subject of this question is Mathematics, specifically ratios and proportions. Given that Omar uses one full head of lettuce for every 5 tomatoes, for 2 heads of lettuce, he will use 10 tomatoes (2*5). Since he uses 1/2 pound of bacon for every 2 tomatoes, then for 10 tomatoes, he will need 2.5 pounds of bacon (10/2*0.5). Finally, since it takes 1/4 pound of bacon to make 4 sandwiches, with 2.5 pounds of bacon he will make 40 sandwiches (2.5/0.25*4). Therefore, Omar will use 2.5 pounds of bacon and make a total of 40 BLT sandwiches.

Answer:

The thirtieth term of sequence is 52

Step-by-step explanation:

Given the A.P series

-6, -4, -2, 0, ...

we have to find the thirtieth term of the following sequence.

The A.P is -6, -4, -2, 0, ...

which implies

Common difference, d=-4-(-6)=-4+6=2

First term=a=-6

n=30

[tex]a_n=a+(n-1)d[/tex]

[tex]a_{30}=a+29d[/tex]

[tex]a_{30}=-6+29(2)=-6+58=52[/tex]

hence, the thirtieth term of sequence is 52

Initial price of car = $x

After one year the price of car = $0.88x

to find the change in price we subtract the price after one year from initial price.

It means change in price = (x-0.88x)= 0.12x

By this we can easily see that , price dropped by 0.12

Or we can say that price dropped by 12%

So option C is the correct answer

C) 12% decrease

In the given data set, the standard deviation is the more appropriate measure of variation as it takes all the scores into account and provides a better insight into the data compared to the range.

In the given data set, both range and standard deviation can be used to measure the variation. However, the standard deviation might be a better measure in this instance. The standard deviation provides a numerical measure of the overall amount of variation in the data set. It indicates how far the values are from their average, or mean. In contrast, the range only provides the difference between the highest and lowest values, potentially overlooking the distribution of all the values.

When calculating the standard deviation for your dataset, it becomes evident that most scores are concentrated around the 90s, but there's one score dramatically lower at 60. This single score skews the data set and increases the standard deviation, indicating a larger spread around the mean than what might first be observed. As such, the standard deviation gives us a more detailed understanding of the spread within this set of quiz scores, making it the more useful measure in this case compared to the range.
