Answer:
Maybe its because you give useless answers to get points.
Idiot.
As far as I remember, we learned a lot about ratios and fractions, such as adding, subtracting, multiplying, and dividing them, as well as finding LCM and GCF.
Answer:
458
Step-by-step explanation:
Margin of error = critical value × standard error
At 99% confidence, the critical value is z = 2.576.
The standard error is σ/√n = 5.4/√n.
Given the desired margin of error is 0.65:
0.65 = 2.576 × 5.4/√n
n = 458
