HELP FIRST GET BRAINLLEST Measure the difference between the lower quartile of Data Set A and the lower quartile of Data Set B. Round to the nearest tenth when performing all operations.
Answers
Answer:
29
Step-by-step explanation:
To find the lower quartile you need to split it into 2 by finding the median
Set A: 73, 75, 79, 81, 84, 85
Set B: 47, 49, 51, 51, 55, 56
Now you have to find the median of each
A: 80
B: 51
Lastly, you subtract and get 29

Answer: 120 lb of potatoes.
Step-by-step explanation:
Let the pounds of potatoes sold by farmer Bill = X lb
Fractional part sold to the first person = 1/4
Therefore 1/4 of X = 1/4 x X
= X/4 lb of potatoes.
No of potatoes left for sale = X - X/4
= ( 4x - x )/4
= 3x/4 lb.
Fractional part sold to the second person out of the reminder = 4/9
Therefore 4/9 of 3x/4 = 4/9 x 3x/4
= x/3 lb of potatoes.
Amount of potatoes left for sale = 3x/4 - x/3
Resolve into fraction , we have = (9x - 4x)/12, because 12 is the LCM.
= 5x/12
Third buyer bought 4/5 of the left over = 4/5 of 5x/12
= x/3 lb of potatoes.
Amount of potatoes left = 5x/12 - x/3
Resolve in to fraction again taking 12 as the LCM = ( 5x - 4x )/12
= x/12 lb of potatoes .
Therefore, the left over was 10 lb .
To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to x/12 = 10
we now cross multiply to get the value of x x = 120 lb.
therefore the pound of potatoes sold by farmer Bill = 120 lb.

To solve an equation like this, make all the percentages into decimals:
-.30
-.25
Now, take 750$ and multiply it by .30 = 225$
Do the same with .25 % = 187.50
Now add the two variables together, and subtract from 750 $
The author will take home = 337.5
50% = $375.00
5% = $37.50
55% = $417.50.
Now we take 55% away from 45% (the ammount she is taking home) which is $332.50

Answer:
X= -11
Step-by-step explanation:
11+3x+x=2x-11 Original
11+4x = 2x-11 Combine Like Terms
22 + 4x =2x Add 11 to both sides
22=-2x Subtract 4x from both sides
x=-11 Divide both sides by -2
11+4x=2x-11
-2x -2x
11+2x=-11
-11 -11
2x=-22
X=-11
