Explanation:
Angles EDF and FDG are congruent due to the similar angle markers. Because of these congruent adjacent angles, we can use the angle bisector theorem to solve for x.
DE/FE = DG/FG
24/x = 54/(x+10)
24(x+10) = 54x .... cross multiplication
24x+240 = 54x
240 = 54x-24x
240 = 30x
30x = 240
x = 240/30
x = 8
From there we can say:
EF = x = 8FG = x+10 = 8+10 = 18EG = EF+FG = 8+18 = 26y'all i just saw the most inappropriate thing.. please... for my eye's sake.. don't post inappropriate things. kids are on this app trying to get answers and learn. do this somewhere else

Fifteen seventh graders were randomly selected to see how many pushups in a row they could do. Their data are shown. a. b. 45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36
Determine the mean of this data set.
Determine the median of this data set.
Answer: Median = 42
Mean = 43.8
Step-by-step explanation:
When we have a data set of n points {x₁, x₂, ..., xₙ}
The mean is written as:
(x₁ + ... + xₙ)/N
And the median will be the value in the middle of the data set.
So first, let's write our data set in order, from least to greatest.
{36, 36, 38, 40, 40, 40, 42, 42, 43, 45, 45, 48, 48, 70}
So we have 14 values.
The middle value will be at:
(n + 1)/2
(14 + 1)/2 = 7.5
Now, counting from the left, we have that the 7.5th value is 42. (the 7th value is 42, and the 8th value is 42)
So the median is 42.
Now the mean:
M = (36 + 36 +38 +40+40+40+ 42 +42 + 43 + 45 + 45 + 48 + 48 + 70)/14
M = 43.8

Step-by-step explanation:
Since the two triangles are congruent this means that corresponding angles are congruent so
Angle X= Angle M
Angle Y equal Angle N
Angle Z equal Angle L.
That means that Angle M is 33 degrees.
Angle Y is 124 degrees.
We can find Angle Z by doing triangle interior theorem.
\(124 + 33 + x = 180\)
\(157 + x = 180\)
\(x = 23\)
So Angle Z equal 23.
Congruent triangles also have corresponding sides that are equal so that means
XY=MN
YZ=NL
XZ= ML
So that means XY=8

7. Assume that when you take a bath, you fill a tub to the halfway point. The portion that you fill measures 6 feet by 2 feet by 2.2 feet. When you take a shower, your use a shower head with a flow rate of 2.23 gallons per minutes and you typically spend 8 minutes in the shower. There are 7.5 gallons in one cubic foot. a. Calculate the cubic feet of water for the bath. b. Calculate the cubic feet of water for the shower. C. How many minutes do you need in the shower to use as much water as the bath?
The volume of water filled in the bath tub is 6 feet × 2 feet × 2.2 feet = 26.4 cubic feet. You need 11.83 minutes in the shower to use as much water as the bath.
The volume of water filled in the bath tub is 6 feet × 2 feet × 2.2 feet = 26.4 cubic feet.
The amount of water used in shower = flow rate × time = 2.23 gallons/minute × 8 minutes = 17.84 gallons
Let's convert gallons to cubic feet: 1 cubic foot = 7.5 gallons
17.84 gallons = 17.84/7.5 cubic feet = 2.378 cubic feet
The volume of water used in the shower is 2.378 cubic feet. The volume of water used for taking a bath is 26.4 cubic feet.
To calculate how many minutes one would need in the shower to use as much water as the bath, divide the volume of water used in taking a bath with the amount of water used per minute in the shower as shown:
26.4/2.23=11.83 min
Therefore, one needs 11.83 minutes in the shower to use as much water as the bath.

The strengths of this study design are:1. Randomization: It is the method of randomly assigning patients to either experimental or control groups. Randomization guarantees that groups would be equal in every respect except for the variable that is being studied.2. Placebo Control: A placebo control group makes it possible to identify the difference between the true effect of the treatment and the effect of other variables that are not being tested.3. Double-blind: When an experiment is double-blind, the experimenter and the patient do not know which group is which. This is important since experimenter bias and expectancy effects can be controlled in the study.

A researcher wants to set up a regression equation where Y is a function X. Evaluate the researcher’s options given the following scenarios: (3)
i. Y is I(0); X is I(0)
ii. Y is I(2); X is I(0)
iii. Y is I(1); X is I(1); and the error term is I(0).
The appropriate regression model depends on the stationarity properties of both the dependent and independent variables, as well as the error term. The researcher can use a standard OLS regression model with first-order differencing of both Y and X.
In the first scenario, both Y and X are I(0), which means they are stationary time series. In this case, the researcher can perform a standard linear regression analysis, as the stationary series would lead to a stable long-run relationship. The answer from this model will be reliable and less likely to suffer from spurious regressions. In the second scenario, Y is I(2) and X is I(0). This implies that Y is integrated of order 2 and X is stationary. In this case, the researcher should first difference Y twice to make it stationary before performing a regression analysis. However, this approach might not be ideal as the integration orders differ, which can lead to biased results.
In the third scenario, Y and X are both I(1) and the error term is I(0). This indicates that both Y and X are non-stationary time series, but their combination might be stationary. The researcher should employ a co-integration analysis, such as the Engle-Granger method or Johansen test, to identify if there is a stable long-run relationship between Y and X. If co-integration is found, then an error correction model can be used for more accurate predictions.

Ian has $6,000.00 to invest for 2 years. The table shows information about two investments Ian can make.
Ian makes no additional deposits or withdrawals. Which investment earns the greater amount of interest over a period of 2 years?
Investment X earns the greater amount of interest over a period of 2 years.
What is simple interest?Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,
SI = PRT
where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.
Let's consider that Ian invests in X, then:
Principle amount, P = $6,000
Time, T = 2 Years
Rate of Interest, R = 4.5% at simple Interest = 0.045
The interest earned is:
Interest = PRT = $6,000 × 0.045 × 2 = $540
Now, consider that Ian invests in Y, then:
Principle amount, P = $6,000
Time, n = 2 Years
Rate of Interest, R = 4% at Compound Interest = 0.04
The interest earned is:
Interest = P(1+R)ⁿ - P
= $6,000(1+0.04)² - $6,000
= $489.6
Since $540>$489.6, therefore, Investment X earns the greater amount of interest over a period of 2 years.

the third and fifth terms of an arithmetic sequence are 2 and 32, respectively. find the explicit and recursive formulas for the sequence
Answer:
see explanation
Step-by-step explanation:
the nth term of an arithmetic sequence is
\(a_{n}\) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
We require to find a₁ and d
given a₃ = 2 and a₅ = 32 , then
a₁ + 4d = 32 → (1)
a₁ + 2d = 2 → (2)
subtract (2) from (1) term by term to eliminate a₁
0 + 2d = 30
2d = 30 ( divide both sides by 2 )
d = 15
substitute d = 15 into (2) and solve for a₁
a₁ + 2(15) = 2
a₁ + 30 = 2 ( subtract 30 from both sides )
a₁ = - 28
Then
\(a_{n}\) = - 28 + 15(n - 1) = - 28 + 15n - 15 = 15n - 43
Explicit formula is \(a_{n}\) = 15n - 43

A recursive formula allows a term in the sequence to be found by adding d to the previous term, that is
\(a_{n}\) = \(a_{n-1}\) + 15 ; a₁ = - 28

If two numbers will be randomly chosen without replacement from $\{3, 4, 5, 6\}$, what is the probability that their product will be a multiple of 9
The probability is\($\boxed{\frac{1}{3}}$.\)
To find the probability that the product of two numbers chosen from {3, 4, 5, 6} is a multiple of 9, we first need to determine the total number of possible pairs of numbers that can be chosen without replacement from this set.
There are \($\binom{4}{2} = 6$\) ways to choose two numbers from the set. These pairs are:
(3, 4), (3, 5), (3, 6), (4, 5), (4, 6), (5, 6)
Next, we need to determine which of these pairs have a product that is a multiple of 9. A number is a multiple of 9 if and only if it is divisible by 9, so the product of two numbers is a multiple of 9 if and only if at least one of the numbers is a multiple of 3.
From the set {3, 4, 5, 6}, only the numbers 3 and 6 are multiples of 3. Therefore, the pairs with a product that is a multiple of 9 are:
(3, 6), (6, 3)
Note that we have listed both (3, 6) and (6, 3) because the order in which the numbers are chosen does not matter.
Therefore, the probability that the product of two numbers chosen from {3, 4, 5, 6} is a multiple of 9 is:
\(\frac{number of pairs with product divisible by 9 }{total number of pairs} = \frac{2}{6} =\frac{1}{3}\)

Substituting a cumulative area of 0.2420, a mean of 0, and a standard deviation of 1 into the inverse normal distribution, the z-score is -0.71 to two decimal places.
Given that the cumulative area of 0.2420, a mean of 0, and a standard deviation of 1, the required z-score has to be determined.We know that the standard normal distribution with mean 0 and standard deviation 1 is denoted as N(0, 1). The inverse normal distribution with a cumulative area of x is the inverse of the normal distribution with cumulative area x. Let z be the z-score corresponding to a cumulative area of x, then we can say that P(Z ≤ z) = x, where P is the cumulative distribution function of the standard normal distribution.
Substituting the given values in the formula, we get:0.2420 = P(Z ≤ z)We need to find the corresponding z-value using inverse normal distribution. Therefore, we take the inverse of the cumulative distribution function, as follows:z = invNorm(0.2420)z = -0.71 (rounded to two decimal places)Thus, the required z-score is -0.71.

In 2022, Skylar sold equipment for $99,800 cash and a $998,000 note due in two years. Skylar's cost of the property was $798,400, and he had deducted depreciation of $479,040.
How much gain can be deferred under the installment sale method?
So the amount of gain that can be deferred under the installment sale method is $424,879.16.
What is percent?Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred" in Latin. When a number is expressed as a percentage, it is usually accompanied by the "%" symbol. Percentages are commonly used in many areas of everyday life, such as finance, taxes, and statistics. They are often used to express changes or differences, such as percentage increases or decreases in prices or quantities, or the percentage of people who hold a certain opinion or belong to a certain group.
Here,
To calculate the gain that can be deferred under the installment sale method, we need to first calculate the total gain on the sale. The total gain is equal to the selling price minus the adjusted basis of the property, which is the cost minus the accumulated depreciation.
Selling price = $99,800 cash + $998,000 note = $1,097,800
Adjusted basis = $798,400 - $479,040 = $319,360
Total gain = $1,097,800 - $319,360 = $778,440
To calculate the gain that can be deferred, we need to determine the gross profit percentage. The gross profit percentage is equal to the total gain divided by the selling price:
Gross profit percentage = Total gain / Selling price = $778,440 / $1,097,800 ≈ 0.7097 or 70.97%
Now we can calculate the amount of gain that can be deferred using the formula:
Gain deferred = Gross profit percentage × Payments received
Since the note is due in two years, Skylar will receive half of the payments in 2022 and the other half in 2023. Therefore, the payments received in 2022 are:
$99,800 + ($998,000 / 2) = $598,800
Substituting into the formula, we get:
Gain deferred = 0.7097 × $598,800 = $424,879.16

The numerator of a fraction is 2 less than the denominator. A new fraction can be formed by adding 5 to the denominator and doubling the numerator. The product of the original fraction and the reciprocal of the new fraction is 1/4. What is the original fraction?
Answer:
\(\frac{6}{5}\)
Step-by-step explanation:
let the denominator of the original fraction be x, then
\(\frac{x-2}{x}\) ← original fraction
Then
\(\frac{2(x-2)}{x+5}\) ← new fraction
The product of original and reciprocal of new is
\(\frac{x-2}{x}\) × \(\frac{x+5}{2(x-2)}\) ← cancel (x - 2)
= \(\frac{x+5}{2x}\) = \(\frac{1}{4}\) ( cross- multiply )
4(x + 5) = 2x
4x + 20 = 2x ( subtract 2x from both sides )
2x + 20 = 0 ( subtract 20 from both sides )
2x = - 20 ( divide both sides by 2 )
x = - 10
Then original fraction
\(\frac{x-2}{x}\) = \(\frac{-12}{-10}\) = \(\frac{6}{5}\)

When the bus left Area A, it was 2/7 full. This means that 2/7 of the bus's capacity was occupied by children. Let's represent the total capacity of the bus as 'x'. Therefore, 2/7 of 'x' corresponds to the number of children on the bus when it left Area A.
After the bus arrived at Area B, 9 children alighted, which means the number of children decreased by 9. We are then told that there were 31 children remaining on the bus. So, the number of children on the bus before any alighted was 31 + 9 = 40.
Since 2/7 of the bus's capacity was occupied by children when it left Area A, we can set up the following equation:
(2/7) * x = 40
To solve for 'x', we can multiply both sides of the equation by (7/2):
x = 40 * (7/2)
x = 140
Therefore, the total capacity of the big school bus is 140 children.
