Right your ratio of

Simplify fraction to 3/4
Now set it up with c/100 to find the percent (c equaling the percentage of caremel brownies)
Cross multiplty:

Crossmultiply:
3c = 200
Divide (solve equation)
c = <span>
66.6666666667</span>
The answer is c so i would pick that beacuse its sounds like a correct answer.
Answer:
325
Step-by-step explanation:
500×.35=175
500-175=325
The z-score is given by:
z=(x-mean)/s.d
the z-score giving us P(0.95)=1.96 and -1.96
thus;
-1.96=(x-1500)/300
-588=x-1500
x=-588+1500
x=912
also:
1.96=(x-1500)/300
588=x-1500
x=588+1500
x=2,088
therefore the sample size of the student picked will be given by:
2,088-912
=1,176
