Answer:
864.36 boxes
Step-by-step explanation:
In the question above, we are given the following values,
Confidence interval 95%
Since we know the confidence interval, we can find the score.
Z score = 1.96
σ , Standards deviation = 15mm
Margin of error = 1 mm
The formula to use to solve the above question is given as:
No of boxes =[ (z score × standard deviation)/ margin of error]²
No of boxes = [(1.96 × 15)/1]²
= 864.36 boxes
Based on the options above, we can round it up to 97 boxes.
2 1/2 = 5/2
<span>ratio : 5/2 : 3/5 (soda to pineapple) </span>
<span>multiply by 2/5 </span>
<span>ratio : 1 : 6/25 (1 unit of soda to 6/25 units of pineapple)</span>
Answer: The approximate total weight of the grapefruits, using the clustering estimation technique is B. 35 ounces.
Find the unit rate :
4 notebooks for 7 bucks.......7/4 = 1.75 per notebook
10 folders for 2.50....2.50/10 = 0.25 per folder
so 5 notebooks = 5(1.75) = 8.75
6 folders = 6(0.25) = 1.50
for a total of : (8.75 + 1.50) = 10.25 <==
