Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
These type of problems could be a little tricky so I'll explain this one as I go.
So the first step I would do is to multiply the 8 in both sides so you end up with...\(x+11=-24\)
After that it should be easier and you'll go at it normally by subtracting the 11 in both sides and that should leave you with the answer of \(x=-35\)

Calculate the residuals for the scatterplot.
Answers
The residuals of the regression are 0.05, -0.5, 0.15, 0.07, 0.35, -0.15, -0.5, -0.15, 0.03 and 0.61
How to determine the residuals?The regression equation is given as:
y = 0.138x + 1.166
Next, we calculate the predicted values (y) at the corresponding x values.
So, we have:
y = 0.138 * 18 + 1.166 = 3.65
y = 0.138 * 21.9 + 1.166 = 4.19
y = 0.138 * 18 + 1.166 = 3.65
y = 0.138 * 20 + 1.166 = 3.93
y = 0.138 * 18 + 1.166 = 3.65
y = 0.138 * 0.7 + 1.166 = 1.26
y = 0.138 * 21.9 + 1.166 = 4.19
y = 0.138 * 0.7 + 1.166 = 1.26
y = 0.138 * 16.7 + 1.166 = 3.47
y = 0.138 * 15.5 + 1.166 = 3.31
The residuals are then calculated using:
Residual = Actual value - Predicted value
So, we have:
Residual = 3.7 - 3.65 = 0.05
Residual = 3.69 - 4.19 = -0.5
Residual = 3.8 - 3.65= 0.15
Residual = 4 - 3.93 = 0.07
Residual = 4 - 3.65= 0.35
Residual = 1.11 - 1.26 = -0.15
Residual = 3.69 - 4.19 = -0.5
Residual = 1.11 - 1.26 = -0.15
Residual = 3.5 - 3.47 = 0.03
Residual = 3.92 - 3.31 = 0.61
Hence, the residuals are 0.05, -0.5, 0.15, 0.07, 0.35, -0.15, -0.5, -0.15, 0.03 and 0.61

a common everyday counting unit that is used to mean 12 of an object is a____
Answers
A common everyday counting unit that is used to mean 12 of an object is a Dozen
Dozen is derived from the Old French word "douzaine" which means twelve each. In most situations, a dozen is used to refer to a group of twelve items. The term dozen is also used in informal situations to refer to a very large number of objects. For example, one might say "I have dozens of friends!" to mean that they have a lot of friends.
Dozen is a useful term when counting items. It allows for large numbers to be easily broken down into manageable groups. For example, if you have 120 pencils, you could easily count them by saying that you have 10 dozen pencils. It can also be useful when talking about fractions. For example, instead of saying "one and a half of an item," one could say "one and a half dozen of an item."
Dozen is a common everyday counting unit that is used to mean 12 of an object. It is a useful term when counting items and when talking about fractions, and can be used in both formal and informal settings.

what is the arithmetic mean of all of the positive two-digit integers with the property that the integer is equal to the sum of its first digit plus its second digit plus the product of its two digits?
Answers
The arithmetic mean is 59.
What is arithmetic mean?
It is the sum of collection of numbers divided by the count of the numbers.
Conider AB is the nuber satisfying the condition. Hence,
\(10A+B=A+B+A\times B\\9A=A\times B\\\)
Since AB is a two digit number hence, \(A\neq 0\\\). Hence, divide both sides by \(A\).
\(9=B\)
Hence, B is 9 and A can take any value from 1 to 9.
Hence, numbers are 19, 29, 39, 49, 59, 69, 79, 89,99.
Now, calculate arithmetic mean as follows:
\(AM=\frac{Sum \ of \ numbes}{Count \ of \ numbers}\\=\frac{19+29+39+49+59+69+79+89+99}{9}\\=59\)
Hence, arithmetic mean of numbers is 59.

4. 4 meters
7. 4 meters
17. 6 meters
20. 6 meters
Answers
At 7.4 ( round to nearsest tenth) meters mark will Ario be present when Miguel starts the race. So, option (c) is right choice here.
We have, Miguel and his brother Ario are both deciding to a race.
Total length of pool = 25 meters
But they are standing 3 meters from one side of a 25-meter pool when both are decide to race.
So, the length of racing area = 25 - 3 = 22 meters.
Also, Miguel said that he will start when the ratio of Ario’s completed meters to Ario’s remaining meters is 1 : 4. Let us assume, the Ario’s completed meters be "x meters" . Then, Ario’s remaining meters = 22 - x
so, x : 22- x = 1 : 4
=> x/(22 - x) = 1/4
=> 4x = 22 - x
=> 5x = 22
=> x = 22/5 = 4.4
Ario position when Miguel starts the race with respect to pool's length = 4.4 meter + 3 meters
= 7.4 meter
Hence, required length is 7.4 meters.

Answers
Use the 3-point curved line drawing tool to draw the average cost curve for quantities q = 1, q = 2, and q = 3. Connect these points smoothly to form the average cost curve.
To calculate the formulas for average fixed cost (AFC), marginal cost (MC), average variable cost (AVC), and average cost (AC) based on the cost function C = 6 + 8q, we can use the following equations: Average Fixed Cost (AFC): AFC = Total Fixed Cost (TFC) / Quantity (q). Since the cost function C = 6 + 8q does not have any fixed cost component, AFC would be zero. Marginal Cost (MC): MC = Change in Total Cost (ΔTC) / Change in Quantity (Δq). The cost function C = 6 + 8q has a constant marginal cost of 8. Average Variable Cost (AVC): AVC = Total Variable Cost (TVC) / Quantity (q). Since the cost function C = 6 + 8q does not have any variable cost component, AVC would be the same as MC, which is 8.
Average Cost (AC): AC = Total Cost (TC) / Quantity (q); AC = (Total Fixed Cost + Total Variable Cost) / Quantity; AC = (6 + 8q) / q; AC = 6/q + 8. Now, for the graphical representation: Use the line drawing tool to draw the marginal cost curve, which is a straight line with a slope of 8. Label this line 'MC'. Use the 3-point curved line drawing tool to draw the average cost curve for quantities q = 1, q = 2, and q = 3. Connect these points smoothly to form the average cost curve. Label this curve 'AC'. Please note that the shape and position of the curves will depend on the specific quantities chosen, but the general trend will be a downward-sloping MC curve intersecting the U-shaped AC curve.

Eric jogged 3 1/4 on Mon, 5 5/8 >; Tues and 8 miles on Wed. Suppose he continues this pattern for the remainder of the week. how far will Eric jog on Fri?
Answers
Sequences
The distance in miles jogged by Eric in the week are shown below:
Mon: 3 1/4
Tue: 5 5/8
Wed: 8
The distances form a pattern which we will recognize below.
Let's compute the differences in the distance of each day with respect to the previous day:
\(r=5\frac{5}{8}-3\frac{1}{4}\)Converting each mixed fraction into improper fractions:
\(r=(5+\frac{5}{8})-(3+\frac{1}{4})=\frac{45}{8}-\frac{13}{4}\)The LCM of the denominators is 8, thus:
\(r=\frac{45}{8}-\frac{13}{4}=\frac{45}{8}-\frac{26}{8}=\frac{19}{8}\)Now we find the same difference between the third and the fourth terms of the sequence:
\(r=8-\frac{45}{8}=\frac{64-45}{8}=\frac{19}{8}\)Since both differences have the same value, the terms of the distances jogged by Eric form an arithmetic sequence. The general term of an arithmetic sequence is:
\(a_n=a_1+(n-1)\cdot r\)Where a1 is the first term, n is the number of the term, and r is the common difference.
We have the values a1=3 1/4= 13/4. r=19/8, thus the distance jogged by Eric on Friday (n=5) is:
\(a_5=\frac{13}{4}+(5-1)\cdot\frac{19}{8}\)Calculating:
\(a_5=\frac{13}{4}+4\cdot\frac{19}{8}=\frac{13}{4}+\frac{19}{2}\)The LCM of 2 and 4 is 4, thus:
\(a_5=\frac{13}{4}+\frac{38}{4}=\frac{51}{4}\)Converting to mixed fraction:
\(a_5=\frac{51}{4}=\frac{48+3}{4}=12+\frac{3}{4}=12\frac{3}{4}\)Eric jogged 12 3/4 miles on Friday

From each new sample, you compute the sample standard deviation. Using the bootstrap method, how can you find the confidence interval for the population standard deviation from these values?.
Answers
Use 2.5th and 97.5th percentile of these values.
Bootstrapping, which is a type of test or metric that mimics the sampling process by using random sampling with replacement, belongs to the larger category of resampling techniques. With bootstrapping, sample estimates are given accuracy ratings such as bias, variance, confidence intervals, prediction error, etc.
A random sample with replacement from the original sample must be taken thousands of times in order to determine the 95% confidence interval for the population standard deviation. You calculate the sample standard deviation from each fresh sample. From the values of the 2.5th and the 97.5th percentile of these data, we can use the bootstrap method to determine the 95% confidence interval for the population standard deviation.
