Answer: I saw on another post on here with the same question that someone said it was
B. The sum of the volumes of X and Z equals the volume of Y.
Answer:
416025
Step-by-step explanation:
For confidence interval of 99%, the range is (0.005, 0.995). Using a z-table, the z-score for 0.995 is 2.58.
Margin of error = 0.2% = 0.002.
Proportion is unknown. So, worse case proportion is 50%. p = 50% = 0.5.
\\ 
So, sample size required is 416025.
First we need to establish the fact that angles on a straight line ALWYS add up to 180
So, we solve the equation for x which turns out to be 3
But,were not done. The question asks us to find the value of the angle BOC
so we substitute the value of x into the equation for BOC (which is 6x+29)
And then your answer is 47 degrees
There are a couple of equations u can use
x = original price
15% off the original price of the purchase :
x - 0.15x
OR
if u get 15% off, then u are paying for 85%
0.85x
