Answer:
x = X + 33 (I am guessing "x" and "X" are not the same. "x" is a variable and "X" is a constant.)
Step-by-step explanation:
31 - X + (2x+1) = x - 1
or, 2x+1 = x - 1 - 31 + X
or, 2x - x = -1 -31 + X -1
or, x = -2 -31 + X
or, x = X - 33

Standard deviation of a sample means
Answer:
statistical metric that is used to measure the extent by which a random variable diverges from the mean of the sampleStep-by-step explanation:
Sample standard deviation refers to the statistical metric that is used to measure the extent by which a random variable diverges from the mean of the sample and it is calculated by adding the squares of the deviation of each variable from the mean, then divide the result by a number of variables minus and then computing the square root in excel of the result.
Hope this helps :}
Pls mark brainliest :P
And have an amazing day <3
Answer:
A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population.

13. Maddie purchased a sofa and a chair for her new apartment. The sofa cost $40 more
than twice the chair. She paid a total of $1252. What did she pay for each one?
The sofa cost $848 while the chair cost $404
Let x represent the cost of the sofa and y represent the cost of the chair.
The sofa cost $40 more than twice the chair, hence:
x = 2y + 40
x - 2y = 40 (1)
She paid a total of $1252, hence:
x + y = 1252 (2)
Solving equation 1 and 2 simultaneously gives:
x = 848, y = 404
Therefore the sofa cost $848 while the chair cost $404

A field is a rectangle with a perimeter of 1200 feet. The length is 200 feet more than the width. Find the width and length of the rectangle field
Answer:
Step-by-step explanation:
let the width be w
p=l*w
1200= 200*w
1200= 200w
1200 = 200w
6 feet = w
width is 6 feet
let the length be a
p = l* w
1200 = a* 6
1200 = 6a
1200 = 6a
200 feet = a
length is 200 feet

Given lines are parallel, find the value of x.
Then determine the measure of the angle.
Answers:
x = 45angle measure = 104 degrees============================================================
Explanation:
These angles are on alternating sides of the transversal line, and they are exterior of the parallel lines. Therefore, these are alternate exterior angles.
Alternate exterior angles are congruent when we have parallel lines like this.
Set the two expressions equal to each other. Solve for x.
3x-31 = x+59
3x-x = 59+31
2x = 90
x = 90/2
x = 45
Then we can find that:
3x-31 = 3*45-31 = 135-31 = 104x+59 = 45+59 = 104Both alternate exterior angles are 104 degrees each, which confirms we have the correct x value.

Which equation is correct?
8 dot 8 equals 8 Superscript 2 equals 16.
9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18.
10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100.
11 dot 11 equals 11 Superscript 2 equals 121.
The equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)
From the question,
We are to determine which of the options is correct.
To determine which of the options is correct, we will evaluate the options one after the other.
For the first option8 dot 8 equals 8 Superscript 2 equals 16
That is,
8.8 = 8² = 16
Evaluating properly
8.8 = 8² = 8 × 8 = 64
Then, 8.8 = 8² ≠ 16
∴ This is NOT correct
For the second option9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18
That is,
9.9 = 2(9) = 18
Evaluating properly
9.9 = 9 × 9 = 9² = 81
Then, 9.9 ≠ 2(9) = 18
∴ This is NOT correct
For the third option10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100
That is,
10.10 = 2(10) = 100
Evaluating properly
10.10 = 10 × 10 = 10² = 100
Then, 10.10 ≠ 2(10) ≠ 100
∴This is NOT correct
For the fourth option11 dot 11 equals 11 Superscript 2 equals 121
That is,
11.11 = 11² = 121
Evaluating properly
11.11 = 11² = 11 × 11 = 121
Then, 11.11 = 11² = 121
This is correct.
Hence, the equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)

Prove that for any natural n the value of the expression (4n+5)^2–9 is divisible by 4.
thank you !!!
please show work, not just the answer
Answer:
4 n (2) + 10 n +4
Step-by-step explanation:
Step-by-step explanation:
Simplify the expression by opening parenthesis:
(4n + 5)² - 9 =(4n)² + 2*5*(4n) + 25 - 9 =4(4n²) + 4(10n) + 4(4) =4(4n² + 10n + 4)As we see the expression has 4 as one of factors so is divisible by 4.
