So the answer is not among the options provided. To find the equation that represents the relationship between the length of the shorter side (x) and the perimeter of the rectangle,
we can use the given information.
Let's denote the length of the shorter side as x. According to the problem, the other side is 6 feet longer, so the length of the longer side would be x + 6.
The perimeter of a rectangle is given by the sum of all its sides. In this case, the perimeter is 100 feet.
The equation to find the length x of the shorter side can be written as:
2x + 2(x + 6) = 100
Simplifying the equation, we have:
2x + 2x + 12 = 100
4x + 12 = 100
4x = 100 - 12
4x = 88
x = 88/4
x = 22
therefore, the correct equation to find the length x of the shorter side is:
2x + 2(x + 6) = 100

The equation to find the length x of the shorter side is x + (x - 6) = 50.
Option (d) is the correct answer.
Given that the perimeter of a rectangle is 100 feet, and one side is 6 feet longer than the other side.
Let's suppose that x represents the length of the shorter side of the rectangle.
Therefore, the length of the longer side of the rectangle is (x + 6).
Using the formula of the perimeter of a rectangle, we get:
Perimeter = 2 × (Length + Width)
According to the problem,
Perimeter = 100
Length = (x + 6)
Width = x
Substituting the values,
Perimeter = 2 × (Length + Width)
100 = 2 × [(x + 6) + x]
50= 2x + 6
x = (50 - 6)/2
x = 22

How do you find the value of x while working with adjacent and vertical angles? The angle is adjacent btw if that helps... I am in 7th grade and need help with this topic
Answer:
The angles are adjacent because they have a common side and vertex. Basically, they are both right next to each other.
x = 28
Step-by-step explanation:
When (x + 6)° and 56° are added together, they need to equal 90° since they are both parts of a right angle.
(x + 6) + 56 = 90
x + 62 = 90
x = 28

If n=100 and p (p-hat) = 0.72, construct a 95% confidence interval. Give your answers to three decimals.
To find the 95% confidence interval when n=100 and p=0.72, we can use the following formula:
$$\left(\hat{p}-z_{\alpha/2} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}, \hat{p}+z_{\alpha/2} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\right)$$
Where, $\hat{p}$ is the point estimate of the population proportion, $n$ is the sample size, $z_{\alpha/2}$ is the critical value of the standard normal distribution at a significance level of $\alpha$, which can be obtained from a table. For a 95% confidence level, $\alpha$ is equal to 0.05/2 = 0.025 on each tail.
The corresponding z-value is 1.96 (approximately).Hence, plugging in the values, we get
$$\begin{aligned}\left(0.72-1.96 \sqrt{\frac{0.72(0.28)}{100}}, 0.72+1.96 \sqrt{\frac{0.72(0.28)}{100}}\right) \\ \left(0.631, 0.809\right)\end{aligned}$$
Therefore, the 95% confidence interval is (0.631, 0.809) rounded to three decimal places.

(1 point) suppose that the trace of a 2×2 matrix a is tr(a)=12 and the determinant is det(a)=32. find the eigenvalues of a. the eigenvalues of a are . (enter your answers as a comma separated list.)
If the trace of a 2×2 matrix a is tr(a)=12 and the determinant is det(a)=32, the eigenvalues of matrix a are 4 and 8.
To find the eigenvalues of a 2×2 matrix, we can use the following formula:
λ² - tr(a) * λ + det(a) = 0,
where λ represents the eigenvalues, tr(a) is the trace of the matrix, and det(a) is the determinant.
In this case, we are given that tr(a) = 12 and det(a) = 32. Substituting these values into the formula, we have:
λ^2 - 12λ + 32 = 0.
To solve this quadratic equation, we can factorize it or use the quadratic formula. Factoring the equation, we get:
(λ - 4)(λ - 8) = 0.
Setting each factor equal to zero, we find two solutions:
λ - 4 = 0 => λ = 4,
λ - 8 = 0 => λ = 8.
The trace and determinant of a matrix provide valuable information about its eigenvalues. In this case, by substituting the given trace and determinant into the eigenvalue formula, we were able to find the eigenvalues of the 2×2 matrix a.

according to a Normal distribution with mu = 138cm and sigma = 7cm
What proportion is between 152 and 124 cm ?
The proportion of values between 152 and 124 cm is 0.8996 or 89.96%.
Proportion between 152 and 124 cm according to a normal distribution with mu = 138cm and sigma = 7cm is 0.8996.
According to the given question, we know that the mean is μ = 138 cm, standard deviation is σ = 7 cm.
We have to find the proportion that is between 152 and 124 cm.
To solve the problem, first we have to find the z-scores for 152 and 124 cm.
We can calculate the z-scores as follows:Z-score for 152 cm is given by:z152=(152−138)7=2z_{152}=\frac{(152-138)}{7}=2z152=(152−138)7=2Z-score for 124 cm is given by:z124=(124−138)7=−2z_{124}=\frac{(124-138)}{7}=-2z124=(124−138)7=−2
We can use a z-table or calculator to find the proportion of values between these two z-scores.
The area under the standard normal curve between z = -2 and z = 2 is approximately 0.8996.
Therefore, the proportion of values between 152 and 124 cm is 0.8996 or 89.96%.

Step-by-step explanation: Marginal Distribution is defined as the probability distribution of variables contained in a subset.
For the American Samoa's military status, marginal distribution is
1) In Armed Forces:
[tex]p_{1}=\frac{87}{55,519}*100[/tex]
[tex]p_{1}=0.15[/tex]

3) Civilian:
[tex]p_{3}=\frac{53,723}{55,519}*100[/tex]
[tex]p_{3}=96.77[/tex]
Now round each percentage to the nearest whole percentage:
Armed forces: 0%
Military: 3%

Answer:
17
Step-by-step explanation:
From Pythagoras :
Hypotenus = sqrt(opposite² + adjacent²)
From the diagram
l = sqrt((l-9)² + 15²)
l² = (l² - 18x + 81 + 225)
Square both sides
l² = l² - 18x + 306
l² - l² = 306 - 18x
18l = 306
l = 306/18
l = 17

Which measures of center or variability are greater than 5 degrees? Select three choices.
the mean of this week's temperatures
O the mean of last week's temperatures
the range of this week's temperatures
the mean absolute deviation of this week's temperatures
the mean absolute deviation of last week's temperatures
The mean absolute deviation of last week's temperatures is 7.2°F.
Given below is the table of last week's and this week's low temperatures:Last week's temperatures: 29°F, 35°F, 42°F, 46°F, 52°FThis week's temperatures: 27°F, 31°F, 35°F, 38°F, 42°F, 46°F, 50°F
The range of this week's temperatures is found by subtracting the smallest value from the largest value. Therefore, the range of this week's temperatures is 50°F - 27°F = 23°F.
Mean absolute deviation is a measure of how much the data deviates from the mean of the data. To find the mean absolute deviation of last week's temperatures, we first need to find the mean of the data set.Using the formula for mean, we have:
Mean = (29 + 35 + 42 + 46 + 52)/5 = 40.8°F
To find the absolute deviations of each temperature from the mean, we need to subtract each temperature from the mean and take the absolute value.Absolute deviations:
|29 - 40.8| = 11.8|35 - 40.8|
= 5.8|42 - 40.8|
= 1.2|46 - 40.8|
= 5.2|52 - 40.8|
= 11.2
Next, we need to find the mean of these absolute deviations. Using the formula for mean again, we have:Mean absolute deviation = (11.8 + 5.8 + 1.2 + 5.2 + 11.2)/5 = 7.2°F

How many different 3-digit odd number can be formed with the digit 0,1,2 up to 9 if the repitition of digits is not allowed
Answer:
The answer is "320".
Step-by-step explanation:
They have to be 1, 3, 5, 7, and 9 as your final digit. Your middle digit may be anything other than the first digit, and only the last digit or 0, is anything.
Now let us take a look at strange digits ending in 1.
This can start from any digit other than 0, so there are 8 options during the first digit.
Its middle digit could only be 1 digit and 1 digit. Even so, it can also be 0, since it has 8 options.
So, [tex]8\times 8 = 64[/tex] strange number ending in 1.
For other strange amounts, the very same logic is working.
And thus there are 64 possible odd numbers for just about any number ending in any of the five odd digits: 1, 3, 5, 7, or 9.
The answer is [tex]5 \times 64 = 320[/tex].

Problem #1: Ms. Barrett is doing an art project with her class. She has 4 sheets of tissue paper. If she gives each student a third of a sheet, how many students will get tissue paper?
Answer:
12 students.
Step-by-step explanation:
If you had 4 sheets, you would want to start by dividing them all in 3's, since that's easiest. (open the file i just for a better example of how the sheet should look).
Now, let's assume these sheets are regular office sized paper.
Start by handing 1 third out to A student.
Now, since there are 4 sheets, divided in 3 sections, we multiply to see the result of how many sections there are.
4 x 3 = 12.
Therefore, 12 students will receive a third of the tissue paper.
