Answer:
90
Step-by-step explanation:
The sum of squares of the deviation from mean=sum(x-xbar)²=?
x
12
6
15
9
18
12
xbar=sumx/n
xbar=(12+6+15+9+18+12)/6=72/6=12
x x-xbar (x-xbar)²
12 12-12=0 0
6 6-12=-6 36
15 15-12=3 9
9 9-12=-3 9
18 18-12=6 36
12 12-12=0 0
sum(x-xbar)²=0+36+9+9+36+0=90
So, the sum of squares of the deviations from the mean is 90.
Amount of ice-cream in the cone = 6.3 in³
Solution:
Given data:
Diameter of the cone = 2 in
Radius of the cone = 2 ÷ 2 = 1 in
Height of the cone = 6 in
The value of π = 3.14
Volume of the cone = 

= 6.3
Volume of the cone = 6.3 in³
Amount of ice-cream in the cone = 6.3 in³
Answer: 149
Step-by-step explanation: <EDG = <EDF + <FDG
=86+66= 149
e know that the measure of arc in degrees is equals the measure of the central angle that intercepts the arc.
Now,the measure of arc EFG is given by Arc EFG=central angle EDG= 149
Answer:
2100
Step-by-step explanation:
5% of 2000 = 2000 x 1/20 = 100.
2000+100=2100
Also, if it said how much interest will her investment PAY, then it would be $100 because of the 5% simple interest.
All real numbers is the answer.
