Answer:
width = 20
length = 28
Step-by-step explanation:
perimeter=96
width=x
length=x+8
(length*2) + (width*2) = perimeter
2(x+8) + 2(x) = 96
2x+16+2x=96
4x+16=96
4x=80
x=20
width = 20
length = 28

Answer:
b. exam completion time is negatively skewed
Step-by-step explanation:
A data distribution is said to be negatively skewed when <em>median</em> value of the distribution is higher than the <em>average</em> value of the distribution.
In this example
- average mid-term completion time is 40 minutes
- median mid-term completion time is 55 minutes.
thus median > mean, so the mid-term completion time is negatively skewed. Negatively skewed distributions are also called left-skewed.
The type of graph that would allow us to quickly see how many students were treated would be a Bar graph.
I think it's 37.5 . I'm pretty sure cause I think you divide 3/8 . Then you go 2 to the right for your answer with the decimal. Not sure but . I think I'm right.
