A rectangle has an area of 36 square units. As the length and the width change, what do you know about their product? Is this length proportional to the width? Justify your reasoning.
Answers
He got a discount of 25%
36/48= 0.75
You then have to subtract this number from 1 (since you're asking for a markdown, not up) and get 0.25.
0.25 x 100 = 25%
The discount is therefore 25%
Alternatively, you could subtract 36 from 48 to get 12, the amount it was marked down by. Then find the percentage of 12 out of 48.
12/48 = 0.25
0.25 x 100 = 25%
Hope this helps :)

Answers
radius, r = Diameter/2 = 28/2 = 14 inches.
C = 2πr
C = 2*π*14
C = 28π
C ≈ 28*3.142
C ≈ 87.976
C ≈ 88 inches
Option D.
diameter=28 in
so the radius is half the diameter
radius=28/2=14 in
Circumference formula=2 × pi × radius
C=2(pi)(14) - pi can be considered as 3.14 or the value in the calculator
C=28(PI)
C=87.96 in ≈ 88 in
The easiest way is just use the diameter times the pi
Because 2 times the radius is just the diameter
So we can derive that
C= diameter × pi
C=d(pi)
C=28(pi)
C=87.96 in ≈ 88 in
The mean and median will increase by the same amount.
B.
The median will increase more than the mean.
C.
The median will stay the same, but the mean will increase.
D.
The mean and median will both stay the same.
Answers
Answer:
Option: D is the correct answer.
Both mean and median stay the same.
Step-by-step explanation:
- We are given a data set as:
4, 6, 8, 10, 12
Clearly from the data set we could see that the median of the set is:
Median=8
( Since we know that the median of the set is the central tendency of a data and always exist in the middle of the data set)
Also, we have 5 data points hence, the mean is calculated as:
Hence, we have:
Mean=8
and Median=8
- Now when we add another point 8 to the set we have the set in increasing order as:
4,6,8,8,10,12
Hence, now the median lies between 8 and 8.
Hence, we get Median=8
( Since, (8+8)/2=16/2=8)
Also, Mean is calculated as:
Hence, we have:
Mean=8
and Median=8
So, the statement that can be inferred form the addition of a new data point is:
D.
The mean and median will both stay the same.
Mean without 8:
Mean is adding all the numbers and dividing by how many numbers there are.
4 + 6 + 8 + 10 + 12 = 40
40 / 5 = 8
So the mean is 8.
Mean with 8:
4, 6, 8, 8, 10, 12
4 + 6 + 8 + 8 + 10 + 12 = 48
48 / 6 = 8
So the mean is 8.
Median without 8:
4, 6, 8, 10, 12
Median is the middle number. In this case it's 8.
Median with 8:
4, 6, 8, 8, 10, 12
Median is the middle number, there are two 8's in the middle, so the median is 8.
Therefore the mean and the median both stay the same.
