To find the median number organize the numbers from least to greatest, like this:
40 40 55 55 55 60 60 65 65 70 70 70
Now just cross the numbers in this order: right to left like this:
40 55 55 55 60 60 65 65 70 70
This way you should find the middle number. If you end up with two numbers as the middle you need to add them and divide by 2 to find the average of the two numbers.
Hope this helps!!

What is the mean absolute deviation for these data?
2.2

6.5
8
Answers
Answer:
2.2
Step-by-step explanation:
If you find the mean of the deviation, you get 2.2
The mean absolute deviation of the data is M = 2.2
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the total number of points be n
Now , the value of n = 10
And , the number of points on each data is given by set A
Now , the value of set A = { 7 , 2 , 8 , 5 , 9 , 9 , 5 , 6 , 8 , 1 }
So , the total sum of data = 7 + 2 + 8 + 5 + 9 + 9 + 5 + 6 + 8 + 1
The total sum of data = 60
Now , the mean number of data points = 60/10 = 6
And , the mean deviation is M
M = 1/10 | [ ( 7 - 6 ) + ( 2 - 6 ) + ( 8 - 6 ) + ( 5 - 6 ) + | ( 9 - 6 ) | + ( 9 - 6 ) + ( 5 - 6 ) + ( 6 - 6 ) + ( 8 - 6 ) + ( 1 - 6 ) |
M = ( 1/10 ) [ 1 + 4 + 2 + 1 + 3 + 3 + 1 + 0 + 2 + 5 ]
M = ( 1/10 ) [ 22 ]
M = 2.2
Therefore , the value of M is 2.2
Hence , the mean deviation is 2.2

Step-by-step explanation:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with XStep 3:
From step 1 above,$80=100
Step 4: Similarly, x=50
Step 5: This results in a pair of simple equations:This results in a pair of simple equations:
$80=100\(1)
$x=50(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
80/x = 100%/50%
Step 7: Again, the reciprocal of both sides gives
x/80 = 50/100
x=40$
Therefore, 50%of 80i s 40

−4x≤12
Step 2: Divide both sides by -4.
−4x /−4 ≤ 12 /−4
= x≥−3

x ≥ -3
Step-by-step explanation:
you add 10 on both sides
-4x - 10 ≤ 2

The perimeter of a rectangular picnic area is 590 yards. It is 100 yards wide. How long is it?
Answers
Answer:
195
Step-by-step explan
Answer:
195 yards
Step-by-step explanation:
remember a rectangle has 4 sides.
100 yards wide is how wide 1 side is. so 2 sides are 200 yards wide.
to determine the width you subtract 200 yards from 590 which give you the answer 390. finally to determine just one side of the length you need to divide 390 in two to get 195 yards.

The Lunchroom Murder
On an otherwise uneventful Thursday afternoon police heard a shot inside the local bistro, Ernie’s Lunchroom. They rushed in and found the scene shown in Figure 1.4.
They identified the body as that of a prominent racketeer named Fannin. Ernie, who is both the owner and only employee, had only one fact to tell: the murderer had leaned against the wall while firing at point-blank range. The imprint of his hand is in clear view.
The police have also noticed that the cash register had just been rung up at $8.75.
This is a difficult case. Your investigative team must attempt to determine which of the people in the lunchroom killed Fannin. You will have to observe the details carefully. There is enough evidence to help you explain most of what happened.

Answer:

Step-by-step explanation:
Hello!
We can solve this by using the Difference of Squares formula:
(a + b)(a - b) = a² - b²47² - 46², the numerator, is very similar to a² - b², so we can extract 47 as a, and 46 as b.
Rewrite the numerator:
47² - 46²(47 + 46)(47 - 46)(93)(1)93We can use the same formula for the denominator the same way:
17² - 14²(17 + 14)(17 - 14)(31)(3)93Rewrite the fraction and simplify:
