Answer:
132cm^3
Step-by-step explanation:
The volume of a cone is 1/3*pi*r^2*h
pi=22/7
r=3
h=14
1/3 * 22/7 * 3^2 * 14 = 132
Answer:
a) (490,510)
b) (480,520)
c) (470,530)
Step-by-step explanation:
Mean, μ = 500
Standard Deviation, σ = 10
Empirical Rule:
- According to Empirical rule almost all data lies within three standard deviation of mean for a normal distribution.
- About 68% of data lies within one standard deviation of the mean.
- About 95% of data lies within two standard deviation of mean.
- About 99.7% of data lies within three standard deviation of mean.
a) 68% of the observations
About 68% of data lies within 490 and 510.
b) 95% of the observations
About 95% of data lies within 480 and 520.
c) All the observations
All of the observations lie between 470 and 530.
Is the x2 supposed to be squared?
Answer:
5
Step-by-step explanation:
When a square root of an expression is multiplied by itself, the result is that expression
5=x
Answer:
2500
Step-by-step explanation:
Let the first square number be then the next square number is .
The difference between these two consecutive numbers is 99.
This implies that:
We expand to get:
Simplify:
Divide both sides by 2
Therefore the value of the larger perfect number is
.
