Answer:
148cm²
Step-by-step explanation:
seriously why, just why? okay, hold on, we're gonna be here a while
Let's start with the triangles, they're all equal, and we already have their measurements and the formula for the area of a triangle is base x height ÷ 2, so all we have to do is plug:
5 x 8 = 40
40 ÷ 2 = 20
Now we have to multiply by 3 because there's 3 of these abominations:
20 x 3 = 60
So we put that on a back burner while we do the semicircle
So the formula for the area of a circle is pi x radius², so we have to find the radius. We know that each of the triangle bottoms is 5cm, so we just multiply by 3:
5 x 3 = 15
So the diameter of the semicircle is 15cm, now we divide that by two to find the radius:
15 ÷ 2 = 7.5
Now we just plug that into our formula (we're using 3.14 for pi)
7.5² = 56.25
3.14 x 56.25 = 176.625
Usually, we'd stop there, but it's only half of a circle, so:
176.625 ÷ 2 = 88.3125
So now we add both of our areas:
60 + 88.3125 =
148.3125
Normally, that would be the answer, but since we're supposed to be estimating, we round it to the nearest whole number:
148.3125 -> 148
So the area of the figure is 148cm²

Answer:
so for the first one, y=4x
meaning y = 4 times x
if y=1, x=4. y=2,x=8 y=3,x=12 etc..
same concept for the other ones.
y=x+6
x=1 then 1+6 = 7, so y=7
x=2 then 2+6 = 8, so y=8
etc
hope this helps
Answer:
See below
Step-by-step explanation:
7. Let's put points in this equation, 1, 2, and 3 will do.
y = 4x
y = 4(1)
y = 4
(1, 4)
y = 4x
y = 4(2)
y = 8
(2, 8)
y = 4x
y = 4(3)
y = 12
(3, 12)
Plot the points, and draw the line. See the first attached graph.
8. Let's put points in this equation, 1, 2, and 3 will do.
y = x + 6
y = 1 + 6
y = 7
(1, 7)
y = x + 6
y = 2 + 6
y = 8
(2, 8)
y = x + 6
y = 3 + 6
y = 9
(3, 9)
Plot the points, and draw the line. See the second attached graph.
9. Let's put points in this equation, 1, 2, and 3 will do.
y = 2x + 1
y = 2(1) + 1
y = 2 + 1
y = 3
(1, 3)
y = 2x + 1
y = 2(2) + 1
y = 4 + 1
y = 5
(2, 5)
y = 2x + 1
y = 2(3) + 1
y = 6 + 1
y = 7
(3, 7)
Plot the points, and draw the line. See the third attached graph.

"How many board games have you played in the past month?"
Step-by-step explanation:
A statistical question is defined as a question that can be answered by collecting data that vary. Basically, it is a question that can be surveyed. The question, "How many board games have you played in the past month?", is the only one that is statistical because multiple different answers can be given to this question.

The radius is 2.1. What is the area of this circle? Round your answer to the nearest tenth. Use 3.14 for pi.
Answer:
Hey!
The area would be 13.85Step-by-step explanation:-
Area of a circle's equation is π[tex]r^{2}[/tex] (pi [tex]r^{2}[/tex])
Since the radius is 2.1 and value of pi is 3.14cm,
area is
[tex]2.1^{2}[/tex] x 3.14
4.41 x 3.14
= 13.85
The area of this circle is 13.6.
What is the area of the circle?Area of a circle is the region occupied by the circle in a two-dimensional plane.
The area of the circle is;
[tex]\rm Area \ of \ circle=\pi r^2\\\\Where\ r =radius[/tex]
The radius is 2.1.
Substitute all the values in the formula
[tex]\rm Area \ of \ circle=\pi r^2\\\\ Area \ of \ circle=3.14 \times 2.1^2\\\\ Area \ of \ circle=13.6[/tex]
Hence, the area of this circle is 13.6.

What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A box plot or boxplot is a method for graphically demonstrating the locality, spread and skewness groups of numerical data through their quartiles.
The interquartile range (IQR) is the width of the box in the box-and-whisker plot.
For first box plot IQR=17-9
=8
For second box plot IQR=14-6
=8
For third box plot IQR=14-5
=9
For fourth box plot IQR=15-8
=7
Hence, the third box plot has the greatest interquartile range
