A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:
Squidward loves playing his clarinet and believes it attracts more jellyfish than any other instrument he has played. In order to test his hypothesis, Squidward played a song on his clarinet for a total of 5 minutes and counted the number of jellyfish he saw in his front yard. He played the song a total of 3 times on his clarinet, and then repeated the experiment using a flute and a guitar. He also recorded the number of jellyfish he observed when he was not playing an instrument. The results are shown in the chart. number of jellyfish attracted to each instrument trial / without music / clarinet / flute / guitar 1 / 5 / 15 / 5 / 12 2 / 3 / 10 / 8 / 18 3 / 2 / 12 / 9 / 17 1) what is the dependent value? 2) what is the independent variable? 3) what should be Squidward’s conclusion? 4) are the results reliable? why or why not?
Answer:
1. The amount of jellyfish attracted ,
2. The type of instrument played ,
3. The guitar attracts the most jellyfish,
4. the results are reliable. there are no big outliers .

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
Several trials are performed with the results shown in the table. What is the experimental probability of randomly drawing a green marble?
Red Blue Green
10 12 28
What is the experimental probability of randomly drawing a green marble?
What is the theoretical probability of randomly drawing a green marble?
What would you expect to happen if more trials of the experiment are performed? Explain your reasoning using complete sentences.
Answer:
experimental
\(p(green \: mable) = ( \frac{5}{24} \times \frac{8}{24} \times \frac{11}{24} ) \\ = 0.03\)
theoretical
\( p(green \: mable) = \frac{12}{25} \\ = 0.48\)

Every time Carrie bakes a batch of brownies, she uses 1/8 cup of chocolate. If she has 1/2 cup(s) of chocolate remaining, how many batches of brownies can Carrie make? Input your answer as a whole number.
1/8 + 1/8 +1/8 +1/8 is the same as 1/2. Each 1/8 represents 1 batch. (1/8*4=4/8 which is equivalent to 1/2)

Solve the inequality m-3 ≥ -2
Answer:
m ≥ 1
Step-by-step explanation:
Step 1: Isolate the variable. (Add 3 to both sides.)
m - 3 + 3 = -2 + 3
m ≥ 1
Answer: m ≥ 1
Step-by-step explanation:
Set up the equation
Add three to both sides
-3 + 3 = 0
-2 + 3 = 1
m ≥ 1

Coordinate Planes
Reading a coordinate planesAxisCoordinate (x, y)Slope-Intercept Form: y = mx + b
m - slopeb - y-interceptSlope Formula: \(\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}\)
Step-by-step explanation:
Step 1: Define
Identify variables.
y-intercept (0, 45)
Point (5, 30)
Step 2: Find Slope m
Simply plug in the 2 coordinates into the slope formula to find slope m.
Substitute in points [Slope Formula]: \(\displaystyle m = \frac{30 - 45}{5 - 0}\)[Order of Operations] Simplify: \(\displaystyle m = -3\)Step 3: Find Equation
Our variables are h (x-axis) and temperature in °F (y-axis). Our slope tells us that for every increase in hours h, the temperature decreases by 3 °F. Our y-intercept tells us what temperature °F it was in the beginning (45 °F).
Substitute in variables [Slope-Intercept Form]: t = -3h + 45And we have our final answer!

10. Jillian calculates to see if it will take 95 minutes to run 7 miles. She runs the distance in 80 minutes. What is Jillian's percent error?
Answer:
8. 10%
9. 50%
10. 15%
Step-by-step explanation:
I am pretty sure I got it right otherwise I think I have a big problem
Answer:
10 kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.
%error=(calculated value - experiemental value)/calculated * 100%
%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error
Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
9 the percent error is 33.3%
8 20% error

Factorise mx+cx+my+cy
With steps!!!
x=algebra x
Step-by-step explanation:
Hey there!
While factorising you remember to make it take common in most of the expression.
Here;
=mx+cx+my+cy
Take common 'x' in "mx+cx" and 'y' in my + cy.
= x(m+c) + y(m+c)
Now, "(m+c)" common again.
= (m+c) (x+y)
Therefore the factorized form of the expression in (m+c)(x+y).
