Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values

Answer:
40
Step-by-step explanation:
70% of something is 28.
We'll use the variable x to hold our value. 70% can be written as 0.7. Rewriting our equation, we get:
0.7 * x = 28.
Lets divide 0.7 over. Our new equation is:
x = 28 / 0.7.
You get that x = 40.
70% of 40 = 28.

The answer is 40

Answer:20.7 units²
Step-by-step explanation: volume of a rectangular prism is L×W×H
therefore 82.8=L×W×the height which is 4 units so if u do 4×L×W you get 4LW which is the volume
(4LW=82.8) now divide 82.8 by 4LW to get the value of LW. The value of LW is an area of one of the bases because area is L×W which is basically LW

1. slope = 12
y-intercept = 1/3
2.slope = 1/4
y-intercept= -12
3.slope = 3
y-intercept = 2
Step-by-step explanation:
When you get an equation for a graph, the co-efficient infront of the x (The number by the x) is the slope.
The equation for the y-intercept:
When solving for y-intercept, you replace y in the equation with 0 and make x the subject.
Example:
y = 12x - 4
0=12x - 4
-12x = -4
divide both sides by negative 12 since we want only positive x
[tex]\frac{-12x}{-12} =\frac{-4}{-12}[/tex]
x = [tex]\frac{1}{3}[/tex]
Therefore, the y-intercept = 1/3

Find the value of c that will make the following two expressions equivalent to 4!!
The answer is 4, Our teacher gave us the answer but I need the work to show how she got it.
2a+10b-8-2(4a-6) and -6a+10b+c
Answers
Answer:
see below
Step-by-step explanation:
We are given 2 equations:
[tex]2a+10b-8-2(4a-6)\\-6a+10b+c[/tex]
We are told to find c to make them equivalent, so we can make them equal to each other:
2a+10b-8-2(4a-6)=-6a+10b+c
To find c, we have to isolate it, here are the steps:
2a+10b-8-2(4a-6)=-6a+10b+c
subtract 10b from both sides
2a-8-2(4a-6)=-6a+c
rearrange left side
2a-2(4a-6)-8=-6a+c
distribute the positive 2 to the terms in parenthesis
2a-(8a-12)-8=-6a+c
distribute -1 to the terms in parenthesis
2a-8a+12-8=-6a+c
simplify
-6a+4=-6a+c
add -6a to both sides
4=c
Hope this helps! :)
