Answer:
mean: $13.50
median: $11
mode: $10
range: $26
hope this helps:)
Answer:
The mean is 13.5, median is 11, mode is 10, and for the range, it's 26
Step-by-step explanation:
For the mean, you add all the numbers up 4+30+10+12+10+20+12+10 = 108. Then you divide by how many terms there are which is 8 and then you get 13.5.
The median is the middle value in a list ordered from smallest to largest. So that is why you get 11.
The mode is the most frequently occurring value on the list and we can tell that 10 is the most occuring in this list.
Finally we have the range. To find the range you subtract the highest amount to the lowest amount. 30 - 4 = 26.
what percent of 7 is 3.5
Answer:
50%Step-by-step explanation:
what percent of 7 is 3.5
3.5 is half of 7, so 100%: 2 = 50%
Answer: 50%
I have shown two methods, both work well and can be used to solve other scenarios as well.
[Method One]
We will set up a proportion and solve.
-> A percent divided by 100 is a decimal. This means 100% = 1 in our proportion
[tex]\frac{1}{7} =\frac{x}{3.5}[/tex]
7x = 3.5
x = 0.5
0.5 * 100 = 50%
[Method Two]
We will put the whole value in the denominator, and the "what percent of" value is the numerator.
[tex]\displaystyle \frac{3.5}{7}[/tex]
0.5
0.5 * 100 = 50%

5/8
Step-by-step explanation:
3 + 1/2 - 2 - 7/8
⇒ 3 - 2 = 1
1/2 - 7/8 = ?
⇒ 4/8 - 7/8 = -3/8
1 - 3/8 = 5/8
Alternative approach:
7/2 - 23/8(converted mixed numbers to fractions)
(7 × 8) - (23 × 2) ÷ 2 × 8
= 56 - 46 ÷ 16
= 10/16

Solve the following system of equations.
x + y = 3
2x + 2y = 6
A) (1.5, 1.5)
B) (0, 3)
C) infinite number of solutions
D) no solution
Answer:
C.
Step-by-step explanation:
x + y = 3
2x + 2y = 6
Multiply the first equation by 2:
2x + 2y = 6
This is the same equation as the second one.
So there are an infinite number of solutions.
Which steps could be part of the process in algebraically solving the system of equations, y + 5x = x² + 10 a
y = 4x -10? Select two options.
Oy=x² + 5x + 10
Oy + 5x = x² + 10 + 4x - 10
00=x²-9x
00=x²-9x + 20
One x-value of a solution to the system is 4.
Answer:
0 = x² - 9x + 20
4 is a solution for the system.
Step-by-step explanation:
y + 5x = x² + 10
y = 4x -10
Replacing the value of y in the first equation. This method is called sustitution.
(4x -10) + 5x = x² + 10
4x - 10 + 5x = x² + 10
4x + 5x - 10 = x² + 10 organizing.
9x - 10 = x² + 10 sum of similar terms.
0 = x² + 10 -9x + 10 organizing.
0 = x² - 9x + 10 + 10 organizing.
0 = x² - 9x + 20 sum of similar terms.
What happens if replace 4 in the equation.
0 = 4² - 9(4) + 20
0 = 16 - 36 + 20
0 = -20 + 20
0 = 0 I find that 4 is a solution for the system.

The present shown below is a cube. Find the surface area.
Answer:
SA = 2,400 cm²
Step-by-step explanation:
Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)
SA = 2(lw) + 2(wh) + 2(hl)
l = 20 cmw = 20 cmh = 20 cmSubstitute the values above and multiply:
SA = 2(lw) + 2(wh) + 2(hl)
SA = 2(20)(20) + 2(20)(20) + 2(20)(20)
SA = 2(400) + 2(400) + 2(400)
SA = 800 + 800 + 800
SA = 2,400 cm²
Final answer: 2,400 cm²

O A. (5.-1)
O B. (5,1)
(
O C. (10,-1)
O D. (10,1)
Answer:
B.
Step-by-step explanation:
Plug in those x and y values into your equations.
(x, y) = (5, 1)
2x + 5y = 15
2(5) + 5(1) = 15
10 + 5 = 15
5x + 10y = 35
5(5) + 10(1) = 35
25 + 10 = 35
This proves those values are true. So the answer is B.

Find a pair of values that make the linear equation y=12x−24 a true statement by filling in the boxes with a valid value of x and y.
Answer:
pair 1: (0, - 24)
pair 2: (1, -12)
Step-by-step explanation:
y = 12x − 24
A pair of values that make the linear equation true:
the easiest value is always 0!!
if x = 0 than plug it in to find y
y = 12(0) − 24 → y = -24
so the pair is (0, - 24)
if x = 1 than plug it in to find y
y = 12(1) − 24 → y = 12 - 24
so the pair is (1, -12)

If A'B' is 8 find the length of AB.
If angle B is 40 degrees what is the measurement of B'?
If angle A is 80 degrees what is the measurement of A'?
Using AA what is the measurement of angle C?
The length of AB when A'B' is 8 is 12

The measurement of A' when A is 80° is also 80°
The measurement of C using AB is 60°
What are similar triangles?Similar triangles are triangles that have the same angles and the ratio of their corresponding sides are equal.
Analysis:
ΔCA'B' is similar to ΔCAB.
Which means [tex]\frac{A'B'}{AB}[/tex] = [tex]\frac{CB'}{CB}[/tex] = [tex]\frac{CA'}{CA}[/tex]
A'B' = 8, CA' = 4, CA = 6
[tex]\frac{8}{AB}[/tex] = [tex]\frac{4}{6}[/tex]
4AB = 8 X 6
AB = 48/4 = 12
Line BA nd B'A' are parallel lines joined by two transversals BC and CA.
So, ∠B = ∠B' = 40°( corresponding angles are equal)
Also, ∠A = ∠A' = 80° ( corresponding angles are equal)
∠A + ∠B +∠C = 180( sum of angles in a triangle)
80 + 40 + ∠C = 180
120 + ∠C = 180
∠C = 180 - 120 = 60°
In conclusion,
The length of AB when A'B' is 8 is 12
The measurement of B' when angle B is 40° is also 40°
The measurement of A' when A is 80° is also 80°
The measurement of C using AB is 60°.
