Mrs. Li wants to compare her students’ test scores to the school average. She created a table to help her. Mrs. Li’s Student Test Scores Student Score compared to school average Adam +3 Bryan 0 Cierra –4 Devaughn +1 Elena +5 Fionna –2 Which list orders the students by lowest score to highest score? Bryan, Cierra, Fionna, Devaughn, Adam, Elena Cierra, Fionna, Bryan, Devaughn, Adam, Elena Elena, Adam, Devaughn, Bryan, Fionna, Cierra Bryan, Devaughn, Fionna, Adam, Cierra, Elena (on edge)
Answer:
B
Step-by-step explanation:
The given differences between the test scores of Mrs. Li's students and the average test score of the school give us the order from lowest to highest marks of Mrs. Li's students as Cierra, Fionna, Bryan, Devaughn, Adam, and Elena. Hence, the 2nd option is the right choice.
What is average of data?The average of data is the ratio of the sum of all observations in the data to the number of observations in the data. It can be written as:
[tex]\overline{x} = \frac{\sum x}{N}[/tex]
where [tex]\overline{x}[/tex] represents the average, x represents the observations, and N represents the number of observations.
How to solve the given question?In the question, we are given the comparison of the test scores between Mrs. Li's students and the school's average test score.
The data is as follows: Adam +3 Bryan 0 Cierra –4 Devaughn +1 Elena +5 Fionna –2, where the shown figure is the difference between their respective score and the average test score of the school.
We are asked to identify the order from the given lists that show the students in order from lowest marks to highest marks.
A negative data means a score less than the average score.
Therefore, Cierra and Fionna got a score less than the average score, with Cierra scoring the least.
A data = 0 means a score equal to the average score.
Therefore, Bryan got a score equal to the average score.
A positive data means a score more than the average score.
Therefore, Adam, Devaughn, and Elena got a score more than the average score, with Elena getting the highest followed by Adam and the Devaughn.
Therefore the order looks like this: Cierra, Fionna, Bryan, Devaughn, Adam, and Elena, which is the 2nd option.

Step-by-step explanation:
Write the equation of the line that passes through the given points.
(0,−1) and (−3,−9)
Let's write the line in slope-intercept form.
y = mx + b
m = slope
b = y-intercept.
Let's use the two points to calculate our slope.
Slope = (-9 -(-1)) / -3 = -8 / -3 = 8 / 3
Our line so far: y = 8/3x + b
Let's plug one of our points into the equation to find b.
-1 = 8/3(0) + b
-1 = b
Our line is: y = 8/3x - 1

Answer:
Step-by-step explanation:
This is a definite maybe kind of question.
Start with the 280. It has a range of 280 +/- 10 mL. That means that each serving is between 270 and 290. If she serves exactly 280 every time she will need 22 * 280 = 6160 mL or 6160/1000 = 6.16 L which gives her a margin of 0.340 L or 340 mL
Consider 270 mL
270 mL * 22 = 5940 mL or 5.94 L She has a little over 1/2 L left over. She has enough soup for 22 people.
Finally think about 290 per serving
290 * 22 = 6380. This should work as well providing she has more than 6.38 Liters which is not a slam dunk. With a leeway of 0.5 L and she only makes 6 Liters, she does not have enough.
So maybe. (Since you can explain this question, you can, I should think, use 0.5 Liters as a leeway).
There is one condition I have not considered and that is what happens if you have 7 Liters of soup? Then the leeway in the serving size does not matter.

pizzas cost $8 plus a $3 delivers charge Show the cost of 1, 2, 3 and 4 pizzas. is there a direct variation? ASAP
Step-by-step explanation:
Write an equation.
c= the cost
p= the number of pizzas
8p means $8 per pizza
And adding 3 includes the delivery charge.
c=8p+3
Plug in the numbers 1-4.
1: $11
2: $19
3: $26
4: $35
This equation is NOT a direct equation since you have to add 3 (for the delivery charge) to the numbers.

Answer:
x= (1/7)hj + (27/7)
Step-by-step explanation:
1) Flip the equation:
7x-27=hj
2) add 27 to both sides
7x = hj +27
3) divide both sides by 7
x = 1/7hj + (27/7)

A doctor has found that, over the years, 95% of the babies he has delivered weighed |x-7.9|<1.5 pounds. What range of weights corresponds to this inequality?
Work Shown:
| x-7.9 | < 1.5
-1.5 < x-7.9 < 1.5
-1.5+7.9 < x-7.9+7.9 < 1.5+7.9
6.4 < x < 9.4
x is between 6.4 and 9.4, excluding both endpoints
The doctor observed over the years that 95% of the babies weighs greater than 6.4 pounds and less than 9.4 pounds.
What is inequality ?Inequality is a mathematical tool for comparing non-equal values.
According to the given question a doctor has found that, over the years, 95% of the babies he has delivered weighed |x-7.9|<1.5 pounds we have to find the range of weights corresponding to this inequality.
|x-7.9|<1.5
∴ x - 7.9 < 1.5
x < 1.5 + 7.9
x < 9.4.
OR
- ( x - 7.9 ) < 1.5
- x + 7.9 < 1.5
- x < 1.5 - 7.9
- x < - 6.4 ( think of moving the terms to other side to make it positive
x > 6.4. and inequality also changes )

R is between S and T. RS = 5x – 13, RT = 2x + 5, and ST = 3x + 24.
Find the value of x and ST.
S
R.
Answer:
The value of x is 8, and m<ST = 48 degrees.
Step-by-step explanation:
With the given information, we know the worth of each angle. To solve it, an equation must be made.
RS (part) + RT (part) = ST (whole)
Should look like this: 5x - 13 + 2x + 5 = 3x + 24.
Then solve the equation.
First, add up all that has in common:
Should look like: 7x - 8 = 3x + 24
Then move 3x from the right to the left by subtraction.
Should look like: 4x - 8 = 24
Next, move the 8 to the other side by addition.
Should look like: 4x = 32
Finally, to find what the value of x is, divide 4 on both sides.
You should get an answer of x = 8.
To find the measurement of ST, replace the x in 3x + 24.
3(8) + 24 = 48.
m<ST = 48 degrees.
