The shape of the histogram is expected to be symmetric.

A histogram is a graphical representation of the distribution of a dataset. It is an estimate of the probability distribution of a continuous variable. The histogram is plotted with bin ranges on the x-axis and the frequency (count) of data points that fall within each bin on the y-axis.

The shape of the histogram can give you a sense of the underlying distribution of the data, such as whether it is symmetric or skewed.

Standardized test scores, like the SAT, are typically designed to have a normal distribution, meaning that the majority of scores fall in the middle range, with fewer scores at the extremely high or low ends.

Additionally, because the data is being collected from a large and diverse population of students from one state, it is unlikely that there would be a significant skew in one direction or another.

However, some factors such as socioeconomic status, family background, school district, and student ethnicity may affect the distribution.

Therefore, The shape of the histogram is expected to be symmetric.

In the first sequence,

let's take ratio of the next term with its preceding term, so we will get the common ratio ~

\(\qquad \sf  \dashrightarrow \: \cfrac{4}{16} = \dfrac{1}{4} \)

So, we can imply that The next term of the sequence is 1/4 times the previous term.

hence, the unknown term will be 1/4 times of previous term.

Therefore, the next term here is 1

In the second sequence,

Do the same procedure as above, we will get common ratio as :

\(\qquad \sf  \dashrightarrow \: \cfrac{18}{6} = 3\)

Therefore, the next term is 162

The median of the set of six numbers is 84.5.

The middle number or central value within a set of data is known as the median. The number that falls in the middle of the range is also the median.

To find the median of a set of numbers, we need to arrange the numbers in ascending order and determine the middle value.

The given set of numbers is {87, 85, 80, 83, 84, x}, and we know that the mean of the set is 83.5.

Let's arrange the numbers in ascending order: 80, 83, 84, 85, 87, x.

Since the mean of the set is 83.5, we can calculate the sum of the numbers and subtract the sum of the known values to find the value of x.

Sum of the known numbers = 80 + 83 + 84 + 85 + 87 = 419.

Mean * Number of values = 83.5 * 6 = 501.

Sum of all numbers - Sum of known numbers = x.

501 - 419 = x.

82 = x.

Now that we have the complete set of numbers: {80, 83, 84, 85, 87, 82}, we can determine the median.

The median is the middle value of the set when arranged in ascending order.

In this case, the median is the average of the two middle values, which are 84 and 85.

Median = (84 + 85) / 2 = 169 / 2 = 84.5.

Therefore, the median of the set of six numbers is 84.5.

It would grow by approximately 1.6668 inches to 1.2504 inches

In Lixue's garden, the green pepper plants grew 5 inches in 3-4 months. To find out how many feet they can grow in one month, we can use the given information.

Let's start by converting the inches to feet. Since there are 12 inches in a foot, we divide 5 inches by 12 to get the equivalent in feet: 5 inches ÷ 12 = 0.4167 feet (rounded to four decimal places).

Now, we need to determine how much they can grow in one month. Since the plants grew 0.4167 feet in 3-4 months, we divide this amount by the number of months to find their average monthly growth.

If we assume that the plants grew 0.4167 feet in 3 months, their monthly growth rate would be 0.4167 feet ÷ 3 months = 0.1389 feet per month (rounded to four decimal places).

If we assume that the plants grew 0.4167 feet in 4 months, their monthly growth rate would be 0.4167 feet ÷ 4 months = 0.1042 feet per month (rounded to four decimal places).

Therefore, based on the given information, the green pepper plants can grow approximately 0.1389 feet to 0.1042 feet in one month, depending on whether we consider a 3-month or 4-month timeframe.

We have to determine whether the given series converges or diverges. The given series is as follows: `(n+4)! / 4!(n!)` Let's use the ratio test to find out if this series converges or diverges.

The Ratio Test: It is one of the tests that can be used to determine whether a series is convergent or divergent. It compares each term in the series to the term before it. We can use the ratio test to determine the convergence or divergence of series that have positive terms only. Here, a series `Σan` is convergent if and only if the limit of the ratio test is less than one, and it is divergent if and only if the limit of the ratio test is greater than one or infinity. The ratio test is inconclusive if the limit is equal to one. The limit of the ratio test is `lim n→∞ |(an+1)/(an)|` Let's apply the Ratio test to the given series.

`lim n→∞ [(n+5)! / 4!(n+1)!] * [n!(n+1)] / (n+4)!` `lim n→∞ [(n+5)/4] * [1/(n+1)]` `lim n→∞ [(n^2 + 9n + 20) / 4(n^2 + 5n + 4)]` `lim n→∞ (n^2 + 9n + 20) / (4n^2 + 20n + 16)`

As we can see, the limit exists and is equal to 1/4. We can say that the given series converges. The series converges. To determine the convergence of the given series, we use the ratio test. The ratio test is a convergence test for infinite series. It works by computing the limit of the ratio of consecutive terms of a series. A series converges if the limit of this ratio is less than one, and it diverges if the limit is greater than one or does not exist. In the given series `(n+4)! / 4!(n!)`, the ratio test can be applied. Using the ratio test, we get: `

lim n→∞ |(an+1)/(an)| = lim n→∞ [(n+5)! / 4!(n+1)!] * [n!(n+1)] / (n+4)!` `= lim n→∞ [(n+5)/4] * [1/(n+1)]` `= lim n→∞ [(n^2 + 9n + 20) / 4(n^2 + 5n + 4)]` `= 1/4`

Since the limit of the ratio test is less than one, the given series converges.

The series converges to some finite value, which means that it has a sum that can be calculated. Therefore, the answer is a).

Replace y with x-1 in the first equation.

Solve for x to get x = 5, which leads to y = 4.

========================================================

Explanation:

Since y = x-1, we can replace every copy of y with x-1 and solve for x.

This is the substitution step. Think of it like a substitute teacher replacing your regular teacher on a temporary basis.

-5x + y = -21

-5x + (x-1) = -21

-4x -1 = -21

-4x = -21+1

-4x = -20

x = -20/(-4)

x = 5 is the first part of the solution

Then this leads to:

y = x-1

y = 5-1

y = 4 as the second part of the solution

Overall the solution as an ordered pair is (x,y) = (5, 4).

---------------

If you wanted, you could plug x = 5 into the first equation and solve for y like so:

-5x+y = -21

-5(5)+y = -21

-25+y = -21

y = -21+25

y = 4

But it's preferable to use y = x-1 since it's more direct.

Brand A sells their product for 36 dabloons per 6 kg. Brand B sells their product for 4 dabloons per 2 kg. Therefore, Brand B is cheaper than Brand A by 2 dabloons per kg in price.

To determine which brand is cheaper and by how much per kg, we compare the prices of both brands based on the cost per kg.

Brand A sells their product for 36 dabloons per 6 kg. We can simplify this to find the cost per kg:

Cost per kg for Brand A = 36 dabloons / 6 kg = 6 dabloons/kg.

Brand B sells their product for 4 dabloons per 2 kg. We can simplify this to find the cost per kg:

Cost per kg for Brand B = 4 dabloons / 2 kg = 2 dabloons/kg.

Comparing the cost per kg, we find that Brand B has a lower cost per kg than Brand A. Therefore, Brand B is cheaper.

To calculate the difference in price per kg between the two brands, we subtract the cost per kg of Brand B from the cost per kg of Brand A:

Difference in price per kg = Cost per kg of Brand A - Cost per kg of Brand B

= 6 dabloons/kg - 2 dabloons/kg

= 4 dabloons/kg.

Therefore, Brand B is cheaper than Brand A by 4 dabloons per kg.

In sum, Nick repays the bank $8,306.25 over the course of the loan's five years.

Let's start by figuring out the total interest during the loan's five-year period. The formula is as follows:

Total interest = principal x rate x time

where:

principal = the amount borrowed

rate = the interest rate (as a decimal)

time = the time period for which the interest is calculated (in years)

Plugging in the given values, we get:

total interest = 5500 x 0.1025 x 5

total interest = 2806.25

So the total interest over the 5-year loan term is $2,806.25.

Therefore, by adding the interest to the principal, we can get the total amount Nick pays to the bank:

total amount = principal + total interest

total amount = 5500 + 2806.25

total amount = 8306.25

Therefore, Nick pays a total of $8,306.25 to the bank over the course of the 5-year loan.

Step-by-step explanation:

The volume of a triangular prism with a height of 3, a length of 2, and a width of 2 is 6 cubic units.

To calculate the volume of a triangular prism, we need to multiply the area of the triangular base by the height. The formula for the volume of a prism is given by:

Volume = Base Area × Height

In this case, the triangular base has a length of 2 and a width of 2, so its area can be calculated as:

Base Area = (1/2) × Length × Width

          = (1/2) × 2 × 2

          = 2 square units

Now, we can substitute the values into the volume formula:

Volume = Base Area × Height

      = 2 square units × 3 units

      = 6 cubic units

Therefore, the volume of the triangular prism is 6 cubic units.
