<h3>
Answers: x = 8 and x = -8</h3>
========================================================
Work Shown:
x^2 + 15 = 79
x^2 = 79-15
x^2 = 64
x = sqrt(64) or x = -sqrt(64)
x = 8 or x = -8
As the steps above show, we first subtract 15 from both sides. Then we apply the square root to get the two results. Don't forget about the plus minus.
Answer:
356
Step-by-step explanation:
We are given that p=0.7, and a 90% confidence interval. Also, we know the margin of error to be 0.04, the sample size is calculated as:
#The sample size is calculated as:
Hence, at least 356 apples must be sampled to get a true proportion with the 4% ME.
0 0 0 1 2 2 4 thats the answer
