a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.
b) The correct expression is given as follows: -8.6b + 28.
How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:
-3.78b + 12 - 4.82b + 16.
This is the step where Maddie made the first error.
Then, to simplify the expression, we combine the like terms, as follows:
b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

The length of the line segment QU diagram containing three right triangles is 3 centimeters.
How find a missing length in a triangle system by similarity propertiesIn the figure given below we have a system of three distinct right triangles connected by three colinear segments. Given that the three triangles are similar, we can make of geometry properties for similarity to determine the length of the missing line segment.
In this question we must find a missing length by similarity properties, which is represented mathematically by proportions. From the figure we have the following relationship:
5/y = (5 - x)/(5 - y) = x/1 (1)
From (1) we have the following two formulas:

Find the sum, S50, of the first 50 terms of the following arithmetic series:(−12)+(−9)+(−6
If you give the working out u will get BRAINLIEST
Answers
Answer:
3075
Step-by-step explanation:
So we have the sequence:
\(-12, -9, -6...\)
As given, this is an arithmetic sequence and we want to find the sum of the first 50 terms.
The formula for the sum of an arithmetic sequence is:
\(S=\frac{k}{2}(a+x_k}\)
Where k is the number of terms, a is the initial term, and x_k is the last term.
We already know that k is 50 because we want to find the sum of the first 50 terms. a is -12 because it's the first number in our sequence. To find our last term, we need to do some more work.
To find the 50th term, let's write an explicit formula for our sequence. The standard form for the explicit formula for an arithmetic sequence is:
\(x_n=a+d(n-1)\)
Where a is the first term, d is the common difference, and n is the nth term.
We already know that a, the first term, is -12. From the sequence, we can see that the common difference d is +3 because each term is 3 more than the previous one. -12 plus 3 is -9, plus 3 is -6, and so on.
So, substitute -12 for a and 3 for d gives us:
\(x_n=-12+3(n-1)\)
So, to find the 50th term for our sum, substitute 50 for n:
\(x_{50}=-12+3(50-1)\)
Subtract:
\(x_{50}=-12+3(49)\)
Multiply:
\(x_{50}=-12+147\)
Add:
\(x_{50}=135\)
So, the last term of our 50 number sequence is 135.
Now, let's go back to our original formula:
\(S=\frac{k}{2}(a+x_k})\)
Now we know all the values. So, substitute 50 for k (the amount of terms), -12 for a (the first term), and 135 for k (the 50th and last term). So:
\(S=\frac{50}{2}(-12+135)\)
Divide:
\(S=25(-12+135)\)
Add:
\(S=25(123)\)
Multiply:
\(S=3075\)
So, our sum is 3075.
And we're done!
Answer:
S₅₀ = 3075
Step-by-step explanation:
Find the sum, S50, of the first 50 terms of the following arithmetic series:(−12)+(−9)+(−6)
an = a₁ + (n - 1) d
where:
a₁ = 1st term = -12
n = nth term = 50
d = common difference
= a₂-a₁ = -9 - (-12) =3
plugin values into the formula:
an = -12 + (50 - 1) 3
= 135
sum of an arithmetic sequence:
Sn = n (a1 + an)
2
S₅₀ = 50 ( -12 + 135 )

S₅₀ = 3075

∡4 = 146°
Step-by-step explanation:
First, we need to find the value of ∡2, and keep in mind that the sum of all the angles in a triangle is = 180°.
Since the triangle is a right angle, we know that the angle to the bottom right = 90°. The other angle is 56°.
Since there are only 3 angles, let's add 56° and 90° to find ∡2.
56 + 90 = 146
180 - 146 = 34°
∡2 = 34°.
Now that we've found ∡2, we need to find out what type of angles ∡4 and ∡2 are.
They are supplementary angles, since they add up to 180°.
Let's subtract 180 - 34 to give us the value of ∡4
180 - 34 = 146
Therefore ∡4 = 146°

Triangle D has been dilated to create triangle D′. Use the image to answer the question.
Answers
Answer: 4
Step-by-step explanation:
Divide the sides of triangle D' by their corresponding sides on triangle D (like 32 divided by 8 and 40 divided by 10). The answer every time is 4 which means the scale factor is 4.
Answer:
The answer is 4
Step-by-step explanation:
In triangle D the top side length is 8 and in triangle D' the top side length is 32. 32 is 4 times 8, and therefore D' was factored by a scale of 4 from D.
This can be done with each side:
8x=32 --> x=4 therefore the scale factor is 4
6x=24 --> x=4 therefore the scale factor is 4
10x=40 --> x=4 therefore the scale factor is 4
