In this question:
We have a population of 500,000, and a sample of 10,000.
10,000/500,000 = 1/50 = 0.02 = 2% of the population, so not representative, and option b is correct.
Ok so first equate all the three equations whether by substituting or by eliminating then choose the one das not the answer
9,276÷8=1,159.5 i hope i helped you i am a 3rd grader
I'm assuming the original equation is
Step 1: Multiply both sides by 2 to eliminate the denominator
Step 2: divide by h
Step 3: subtract a
