Answer: 5 ounces
3 ounces of blackberries
2 ounces of raspberries
0 ounces of strawberries
================================================
Explanation:
The pie needs
- 9 oz of blackberries
- 10 oz of raspberries
- 12 oz of strawberries
Each container at the store is 12 oz of berries
After making 1 pie, he'll be left with...
- 12-9 = 3 oz of blackberries
- 12-10 = 2 oz of raspberries
- 12-12 = 0 oz of strawberries
That makes 3+2+0 = 5 ounces of berries total
Answer:
a)0.154<p<0.48[
b)n≅ 6.57
c)n=2401
Step-by-step explanation:
n = 60
Sample proportion = p = 16/60 = 0.266
a) Find a 95% two-sided confidence interval on the true proportion of helmets
90 % confidence interval fro population is
hence population proportion lies in the confidence interval
b) helmets must be tested to be 95% confident
point of estimates i s- 0.266
Margin of error = 0.02
after putting values we get
n = 6.56
n≅ 6.57
c)large must the sample be
The sample is calculted as
n=2401
X = # adults
y = # children
system
24x+16y=$10272
x + y =532
