8x-8=72
+8 +8

8x=80

8x/8 80/8

X=10

1st step do the opposite of subtracting which is adding so add 8 on each side like shown above .

2nd step after adding and canceling you bring down 8x=80

3rd step you need to get x by itself so divide 8 in each side shown above

4th step the answer is X=10

To compare two products such as colas, a random sample is selected to taste two types of colas (A and B). Each selected subject

Answer: The sample size would be needed = 385

Step-by-step explanation:

Let p be the prior population proportion.

Margin of error = E

When not estimate of p is given , the formula to calculate the minimum sample size <em>n</em> = $0.25(\dfrac{z^*}{E})^2$ , where z* = critical value for given confidence interval.

Here z* for 95% confidence level is 1.96.

E=5%=0.05

Then $n=0.25(\dfrac{1.96}{0.05})^2\approx385$

Hence, the sample size would be needed = 385
