The two-dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on visual inspection of the dot plots, which group appears to have the longest average forearm length?
Group B, because three children in the group have the least forearm length of 11 inches
Group A, because three children in the group have the least forearm length of 11 inches
Group A, because seven children have a forearm length longer than 12 inches
Group B, because two children have a forearm length longer than 12 inches
Answers
Answer:
Group A because seven children have forearm length longer than 12 inches
Step-by-step explanation:
We need to look at Group A and everything after 12 inches. If we look at 13 inches, there is four dots. And if we look at 14 inches, there are three dots. Add then together to get seven children's forearm lengths.
The group which appears to have the longest average forearm length is group Group A since seven children have a forearm length longer than 12 inches.
What is Dot Plot?Dot plots are one of the form of graphing points using dots which indicates the value on a number line.
Given are two dot plots.
In both groups, there are a total of 10 children.
It is clearly seen that from group A, 3 children have a forearm length of 12 inches, 4 children have a length of 13 inches and 3 children have a length of 14 inches.
On an average, 7 children have more than 12 inches forearm length.
Similarly, for group B, only 2 children has a forearm length of more than 12 inches.
So group B has longest average forearm length.
Hence the correct option is Group A, because seven children have a forearm length longer than 12 inches.

What steps should be taken to calculate the volume of the right triangular prism? Select three options.
A triangular prism. The triangular base has a base of 8 meters and height of 14 meters. The height of the prism is 7 meters.
A. Use the formula A = one-half b h to find the area of the base.
B. Use the formula A = b h to find the area of the base.
C. The area of the base, A, is One-half (7) (8) = 28 meters squared.
D. The area of the base, A, is One-half (8) (14) = 56 meters squared.
E. The volume of the prism, V is (56) (7) = 392 meters cubed.

Twenty-nine equals the sum of 11.5 and the quotient of a number and 2.5.
29 equals 11.5 plus m over 2.5; m = 43.75
29 equals 11.5 plus m over 2.5; m = 7
29 = 11.5 + 2.5m; m = 43.75
29 = 11.5 + 2.5m; m = 7
Answers
Answer:29=11.5+(M/2.5), m=43.75
Step-by-step explanation:
The equation of the statement is 29 = 11.5 + m/2.5 and value of m = 43.75.
What is an equation?An equation states that both sides of the equality sign are equal.
We know we can form numerical expressions in terms of numbers and their operation from given statements.
Let us assume the unknown number to be m.
Given Twenty-nine equals the sum of 11.5 and the quotient of a number and 2.5 which can be numerically expressed as,
29 = 11.5 + m over 2.5.
29 = 11.5 + m/2.5.
To get rid of the fraction we are multiplying each term by 2.5.
72.5 = 28.75 + m.
m = 72.5 - 28.75.
m = 43.75.

Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

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).
y = -15x - 5.

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

What theorem uses a rotation then reflection
Answers
Hello!
I see this question relates to mathematics in the topic, geometry.
I have personally learned about rotations and reflections, and would like to knowledge you to the best of my abilities based on the question you have asked.
A rotation and reflection are all translations.
Translations move the figure but don't change its size.
A dilate changes the size of the figure by a scale factor.
All of these mentioned are transformations.
I am not sure if there is a theorem that used rotations and reflections, but i do no that rotations and reflections are both translations.
I hope you found this well,
And have a wonderful day.

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.
