Answer:
It is decreased by 3.25
Step-by-step explanation:
When you add all 8 numbers you'll get 58 then you divide them by 8 you will get 7.25 which is the mean. To find out what is the decrease we need to take out the 30 and add all the other numbers and we get 28. After that you divide 28 by 7 and you get 4. Subtract 4 from 7.25 and you get 3.25.
2+2+2+3+5+6+8+30=58
58/8=7.25
2+2+2+3+5+6+8=28
28/7 = 4
7.25-4=3.25

Data Set: 5, 8, 10, 10, 15, 18, 23. What is the upper quartile limit (Q3) of this data set? *
Answer:
15, 18, and 23
Answer:
Q₃ = 18
Step-by-step explanation:
The first step is to find the median
The median is the middle value of the data in ascending order.
5, 8, 10, 10, 15, 18, 23
↑ middle value
median = 10
The upper quartile Q₃ is the middle value of the data to the right of the median, that is
15, 18, 23
↑ middle value
Thus Q₃ = 18

1/3 / 4 = 1/4 x 1/?
Solve what you can:
1/3 * 1/4 = 1/4 * 1/?
Multiply one side
1/12 = 1/4 * 1/?
Just put ? as X
1/12 = 1/4 * 1/X
1/12 = 1/4x
Multiply both side by 12
12 = 4x
Divide both sides by 4
3 = x
X = 3 bois
What is the solution of the equation 1/4 x - 2y = 12, when y = -1?
A. X = 4
B. x = 6
C. X = 40
D. X = 48

Answer:
She will pay $19.08

6/100=0.06
15(0.06)=0.90
15.00+0.90=15.90
20/100=0.2
(15.90)(0.2)=3.18
15.90+3.18=$19.08

The side length of a square is 7 units. The square is reflected over the x-axis in the coordinate plane.
What is the length of the side of the image?
The length of the side of the image is 7 units.
What is the reflection on x-axis?When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).
Given that, the side length of a square is 7 units.
The square is reflected over the x-axis in the coordinate plane.
A reflection is an isometry, which means the original and image are congruent, that can be described as a "flip".
Therefore, the length of the side of the image is 7 units.

Answer:
B is the correct answer.
if Sonja makes $2100 interest after investing $15,000 at 2.8%, how many years did she invest for?
Answer:
Sonja invested for 5 years.
Step-by-step explanation:
First you have to find how much money she gets in one year.
To do this you would have to multiply 15,000 and 2.8.
15,000 x 2.8 = 42000
You move the decimal 2 spaces forward since there are 3 zeros in 15,000 and one decimal place in 2.8.
This gives you 420.
To find how many years it takes for her to make $2100 you have to divide
2,100/420.
This gives you 5, which means that she invested for 5 years.
