Answer:
65.4% to 74.6%
Step-by-step explanation:
68% is approximately plus minus 1 standard deviations.
sigma=sqrt(n*p*(1-p))=sqrt(100*.7*.3)=4.58
so we're looking at 70+4.6 and 70-4.6.
Answer:
Tan B = 15 / 8
Step-by-step explanation:
Giveb the triangle :
The hypotenus :
Using Pythagoras rule :
Hypotenus² = 15² + 8²
Hypotenus² = 225 + 64
Hypotenus = 17
Tan B:
Using the trigonometric relation :
Tan B = opposite / Adjacent
Tan B = 15 / 8
The answer is 25%
(1)
If 64 is 100%, 48 is how much percent:
64 : 100% = 48 : x
x = 100% * 48 : 64
x = 75
(2)
Percent of decrease is:
100% - x = 100% - 75% = 25%
Answer:
