24 cookies 54 cookies
cross multiply
2*54=24x
24x=108
x=4.5
4.5 cups of flour
Tan(30deg) = n/rt(3)
1/rt(3) = n/rt(3)—> n=1
sin(30deg) = 1/m
1/2=1/m—> m=2
Thus m=2 ,n=1
The answer is very simple is 3 .
Each neighbor gets 4 slices of pie.
Answer: 196
Step-by-step explanation:
As per given , we have
Population standard deviation: 
Significance level : 
Using the z-value table , the critical z value for 98% confidence : 
Margin of error : E= 01 lb
Sample size : 

Simplify , we get

Hence, the minimum sample size required for books = 196
