Answer:
both are c
Step-by-step explanation:
Answer: Choice E) bimodal skewed
The majority of the data is towards the left side. The right outliers are skewing the mean to be pulled larger than it should be. This is why median < mean, so it's better to use the median as the measure of center. There are 2 modes here. They are the values 4 and 8 since we have these values occur the most (4 times each). That's where the term "bimodal" comes in.
Answer:
Width = 160
Length = 110
Step-by-step explanation:
Perimeter is the sum of all the sides
They tell you that the length is 50 m shorter than the width
so L = W - 50
W = W
540 = W + W + W-50 + W-50
540 = 2W + 2(W-50)
540 = 2W + 2W - 100
540 = 4W - 100
640 = 4W
W = 160
L = 160 - 50
L = 110
Answer:
16.373,16.4
