we have the data set
3,1,7,0,4
step 1
Find out the sample mean
sample mean=(3+1+7+0+4)/5
sample mean=15/5
sa,ple mean=3
step 2
Complete the table
x (x-mean) (x-mean)^2 x^2
3 (3-3) (3-3)^2 0
1 (1-3) (1-3)^2 4
7 (7-3) (7-3)^2 16
0 (0-3) (0-3)^2 9
4 (4-3) (4-3)^2 1

15 30
Find out the standard deviation of the sample
SD=√(30/n-1)
SD=√(30/5-1)
SD=2.74
Answer: (A)
Explanation: For there to be a solution at any one point, both inequalities must share a common point. This point will then satisfy both inequations, becoming a solution to both inequality.
Let's pick (A).
For there to be at least one solution, the first inequality must have a solution of

. Since the left side has clearly no points common to both graphs. Hence, no solution can exist that will satisfy both.
All of the other graphs have at least one point in common.
(B) has

(C) has

(D) has
Answer:
30 meters
Step-by-step explanation:
Volume of a cylinder = πr^2h
2,827.43 = πr^2(4)
2,827.43 = 3.14(4)r^2
2,827.43 = 12.56*r^2
2,827.43/12.56 = (12.56*r^2)/12.56
225.11 = r^2, find square root of both sides
r = 15
diameter = 30
340 sq in. because (10*10=100) (10*12/2=60) (4*60=240) (((240+100=340)))
