Answer:
A.) What is your favorite subject this year?
Step-by-step explanation:
A statistical question is a type of question that can't be answered with just one number or value. It has to have different responses for different types of people in different situations. An example of a statistical question is "What do you do afterschool?" because every person does different things afterschool. The only question that has different responses for different people is the first one, "What is your favorite subject this year?".

Step-by-step explanation:
A circular placemat has 44 inches of braid around the edge. What is the area of the placemat to the nearest square inch? Use 3.14 for π.
Enter the correct answer in the box.
[ ]
==========================================================
Explanation:
We'll need to use the circumference formula
C = 2*pi*r
to find the value of the radius r when C = 44
So we get
C = 2*pi*r
44 = 2*3.14*r
44 = 6.28*r
6.28r = 44
r = 44/6.28
r = 7.0063694267516
which is approximate
Then we use this value of r to find the area we need
A = pi*r^2
A = 3.14*(7.0063694267516)^2
A = 154.140127388536
A = 154
The area of the circular placemat is approximately 154 square inches.
Answer:
a ~ 154
a = [tex]\frac{484}{(pi)}[/tex]
Step-by-step explanation:
1. Approach
In this problem, one is given the circumference, the distance around the circle, one must find the area. In order to find the area, one must know the radius of the circle. To find the radius, one has to backsolve from the given circumference, then substitute the derived value into the formula for the area and solve.
2. Find the radius
The formula to find the circumference of a circle is;
[tex]2r(pi)=c[/tex]
Where (r) is the radius, (pi) is (3.1415), and (c) is the circumference.
Substitute in the given values and solve;
[tex]2r(pi) = c\\2r(pi) = 44\\r=\frac{44}{2(pi)}\\r=\frac{22}{(pi)}[/tex]
3. Find the area
Now, one has the value of the radius, substitute it into the formula for the area of a circle and solve;
The formula for finding the area of a circle;
[tex](pi)r^{2}=a[/tex]
Where (pi) is (3.1415), (r) is the radius, and (a) is the area,
Substitute in the value and solve.
[tex](pi)r^{2} = a\\(pi)(\frac{22}{(pi)})^{2}=a\\\frac{(22)^{2}}{(pi)}=a\\\frac{484}{(pi)}=a[/tex]
a ~ 154

A circular tablecloth has a radius of 2.5 feet. Kyle is sewing a piece of ribbon around the edge of the tablecloth. If Kyle has exactly enough ribbon, which measurement is closest to the length of the piece of ribbon in feet?
Answer:
15.7 feet I hope that helped!
plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
Answer:
1. 4 is the constant
2. x > -2
3. 2.86 inches
^The formula for the circumference of a circle is C=2∏r, in which r=radius. To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.
hope this helped:)

Is t = 12 a solution to the inequality t ≥ 12
Yes or No
Answer:
Yes, it is a solution.
Step-by-step explanation:
Since t ≥ 12 means that t needs to be equal to or greater than 12, t = 12 works as a solution because it is equal to 12.

The shape of the image of ΔABC following a dilation by a scale factor of [tex]\dfrac{2}{3}[/tex] is the same as the shape of ΔABC but the sizes of the sides of ΔA'B'C' are [tex]\dfrac{2}{3}[/tex] smaller
The correct options with regards the given statements are;
The measure of ∠B and ∠B' are equal is TrueThe coordinates of A and A' are the same is TrueReasons:
The dilation lengths of the sides of ΔABC are AB, AC, BC
The given scale factor of dilation = [tex]\dfrac{2}{3}[/tex]
Therefore;
The lengths of the sides of ΔA'B'C' are [tex]\dfrac{2}{3} \cdot \overline {A'B'}[/tex], [tex]\dfrac{2}{3} \cdot \overline {A'C'}[/tex], [tex]\dfrac{2}{3} \cdot \overline {B'C'}[/tex]
Which gives;
[tex]\dfrac{\overline{A'B'}}{\overline{AB}}} = \dfrac{\overline{A'C'}}{\overline{AC}}} = \dfrac{\overline{B'C'}}{\overline{BC}}} = \dfrac{2}{3}[/tex]
Given that the ratio of the corresponding sides of ΔABC and ΔA'B'C' are equal, ΔABC is similar to ΔA'B'C' by triangle similarity theorem
Therefore;
∠A = ∠A', ∠B = ∠B', and ∠C = ∠C' by definition of triangle similarity
Which gives;
The statement; The measure of ∠B and ∠B' are equal is True
Second part;
The center of dilation of ΔABC is point A, therefore, the distance between point A and point A' following a dilation is zero
Therefore, given that there is no difference, we have;
The coordinates of point A = The coordinates of point A'
Therefore;
The statement, the coordinates of A and A' are the same is True

Answer:
False
True
Step-by-step explanation:
A dilation multiplies the distance of every point from the center of dilation by the scale factor. So a dilation moves every point except the center of dilation.
Point A is the center of dilation, so the coordinates of A and A′, are the same.
Dilations multiply every length in the figure by the scale factor, so AB and A'B' do not have the same length.
