3. entry to a certain university is determined by a national test. the score
for the tests are normally distributed with a mean of 500 and a standard
deviation of 100. tom wants to attend this university and he knows that
he must score better than at least 70% of the students who took the
test. tom takes the test and scores 585. will he be admitted to this
university?

10:40

Step-by-step explanation:

I believe the answer would be 10/40. First, I simplified all of the given rations. You do this by finding the two numbers greatest common factor. For example, 3/12, 3 goes into 3 once and 3 goes into 12 four times. So that ratio would be 1/4. If you continue the pattern you would get 1/4 for all of them. Therefore, 10/40 would be correct since it's ratio would also be 1/4.
