None of the above, 3<span>× 3 × 3 × 3 × 3 × 3 × 3= 2187, 7 x 3= 21, 7x7x7= 343, and 7+7+7 is 21.</span>
It follows from the definition of the binomial coefficient:
So we have
That is, gets absorbed into the numerator's factorial, and we introduct into the denominator. Now, , so we get
as required.
First, we see the closest multiple of 7 under 100 is 98 and that divided by 7 is 14. there are 2/7 as our remainder. We do 2/7 times 160 to get 320/7 and 320/7 = 45 and 5/7. We convert 5/7 into a decimal like 5/7 = .7. The answer is 45.7 milligrams of sodium.
