Mathematics

4a.  13 out of 8,000 is about 1 in 600, so that is about the probability that the next one will be defective.
4b.  1 in 600 is a lot less than 1%, so the manufacturer did reach his goal.

By the way, ithink the one above these might be wrong.  i think you have calculated the probability of the next one being chipped, rather than ofthe next one, not being chipped. So I am guessing that the answer ofr that one should be 24/25.

MakcuM [25]

Answer:

Equation: 4 1/4 + 1 3/4

Evaluation: 5 3/4

Step-by-step explanation:

So, Nora jobs 4 1/4 miles on Monday, which is 1 1/2 miles fewer than on Tuesday.

If this was 1.5 fewer miles, we need to add 1 1/2 and 4 1/4  to get our answer

We change the denominator on 1 1/2 to be 4. So, we multiply both sides by 2 and get 1 2/4

4 1/4 + 1 2/4 = 5 3/4
