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.
Answers
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:
1. Angles are complementary which means they add up to 90°
3x + 6 + 2x - 11 = 90° (angles are complementary)
5x - 5 = 90
5x = 90 + 5
5x = 95
x= 95/5
x= 19
Therefore
m∠G = 3x+6
= 3(19)+6
= 63°
m∠H= 2x-11
= 2(19)-11
= 27°
2. Angles are supplementary which means they add up to 180°
m∠J + 29 = 180°
m∠J= 180-29
m∠J =151°
Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

The area of a circle is pi(9x2 + 6x + 1) square cm. Find an expression for the length of the circles radius
Answers
Answer:
r = 3x + 1
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here
πr² = π(9x² + 6x + 1) ← divide both sides by π
r² = 9x² + 6x + 1 ← perfect square
r² = (3x + 1)² , thus
r = 3x + 1

the percent change in the amount the group raised is 10%.
Step-by-step explanation:
% change = (new value - old value) old value x 100 = (1,045 - 950)/950 x 100 = 95/950 x 100 = 0.1 x 100 = 10%
Cycle City charges an initial price of $15 plus $0.75 per house for bike rentals, which is represented by the expression 15 + 0.75h .
Complete the statement to describe the terms...
Answers
Answer: see below
Step-by-step explanation:
h represents the number of houses. How i know this:
(1) the question states that each house costs $0.75. So 0.75h means 0.75 times a number of houses.
(2) h is used because houses starts with h. Also, h can't represent bikes because the "bikes" only appears in 1 number and doesn't have anything per bike. It only appears once.
15 represents the initial price of bike rentals.
- It says in the question, "Cycle City charges an initial price of $15 plus $0.75 per house for bike rentals". All of the information related to what 15 stands for is underlined. "Initial price" means a 1 time price that doesn't repeat. the 0.75 repeats based on how many houses you get.
0.75h represents the total cost for any number of houses.
(1) The question says "$0.75 per house" which means that each house costs 0.75. The h next to the 0.75 only means a number of houses. Whenever you see "something per something", expect the first letter of the 2nd word to be placed after the number.
If it doesn't make sense, let's say that h=1. In other words, we are buying 1 house. 0.75h means 0.75xh, so 0.75x1= 0.75. It's true. 1 house costs 0.75. You can also do 0.75x2, 0.75x3, and so on.
I hope i could help :)))
Answer:
Step-by-step explanation:
h= number of houses
0.75= cost per house
15= the initial price (price first paid)

What is a fraction?
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have an expression:
= 3(2/5) + 1(3/10)
1):
= 3(2/5) + 1(3/10)
= 17/5 + 13/10
2):
Multiply with 2 in the term 17/5 on numerator and denominator
= 34/10 + 13/10
3):
= 34/10 + 13/10
= 47/10
Thus, the expression 3(2/5) + 1(3/10) in the improper fraction is (A) 17/5 + 13/10, with a common denominator is (C) 34/10 + 13/10, and after adding it will be (B) 47/10.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get

Solve this system of equations by using the elimination method. Please help! Thank you! ( ・・)つ♡
Answers
Answer: x = 1, y = 2
Step-by-step explanation:
So elimination is basically big subtraction.
instead of subtracting two numbers, your subtracting two equations;
so heres how it works.
We see that both equations have a common term of 4y, and since the signs of the "4y" term are alternating in the equations, (one is a + the other is a -), we can add the equations, which will cancel out the 4y.
(Basically, im saying 4y - 4y = 0)
So:
x + 4y = 9
2x - 4y = -6
+
------------------------
3x + 0 = 3
I hope you see how that works. its just like writing out a sum with numbers.
Anyways, we get 3x = 3, so x = 1, (divide both sides by 3).
Now that we know x, we can plug this value into either of the equations to get y.
ill use the first one:
x + 4y = 9
1 + 4y = 9
4y = 8
y = 2
And thats it!
x = 1, y = 2
