49^(3/2)
This is the same as (sqrt49)^3
7^3 = 343
You slowly go down the bottom row and multiply each digit by the top row.
Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 ×
× 
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 ×
× 
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 ×
+ 15C5 × 
P =
( 15C8 + 15C5 )
P =
( (
) + (
) )
P =
( 6435 + 3003 )
P =
( 9438)
P =
( 4719)
P = 
P = 0.29
SOLUTION:
We are to find the rate of inflation in the given question;
The formula to be used is;
Inflation rate =


CONCLUSION
The inflation rate of CPI that increased from 208 to 221 to the nearest tenth of a percentage is 6.3%.
Answer:
Volume = 1/3 πr^2 h
Therefore,
Volume = 1/3 π × (2.81)^2 × 7.5
= 62.015 ~ 62.02
Hope it helps!
