Answer:
A. mean=14.29
median=16
B. IQR=10
C. option 3
D. 5.91
Step-by-step explanation:
mean=sum of values/number of values=10+20+4+13+21+16+16/7=14.29
median is achieved by arranging data in increasing order and then calculating the middle value
4 10 13 16 16 20 21
The mid value is 16 so the median=16
IQR=interquartile range=3rd quartile-1st quartile=Q3-Q1=20-10=10
As n/4=7/4 is not an integer so
Q1=(n/4+1)value=(7/4+1)=2.75=2nd value=10
Q3=(3n/4+1)value=6.25=6th value=20
Standard deviation=s=sqrt(∑(x-xbar)²/n-1)=sqrt(209.43/6)=5.91
The area of the circle is equal to the area of the polygon
Answer:
And by definition the radius would be lower than the diameter and we have the following relationship:

And then the best answer would be:
B 2r
Step-by-step explanation:
When we have a circle we know that the area is given by:

And we also know that the diameter is the distance between two any points in the circle passing through the center.
And by definition the radius would be lower than the diameter and we have the following relationship:

And then the best answer would be:
B 2r
Answer:
It equals 72
Step-by-step explanation:
24 x 24 x 24 = 72
Answer:
-2.595
Step-by-step explanation:
When inputting this function into your calculator, we need to be aware of a couple things:
1.) his is ln(1.5) - 3, and not ln(1.5-3). Negative numbers cannot be put into the natural log function.
2.) That is because lnx is another way of saying
. If you're having trouble finding ln on the calculator, use logx/loge (an odd rule that you'll learn soon from the looks of it.)
