15 + 5m = 415<br><br> Can you help me find m?
Ann [662]
All you have to do is isolate m. We have to move all terms except m to the other side.

15 + 5m = 415

We have to cancel out the numbers. 15 is being added so we subtract it from both sides.

15 - 15 + 5m = 415 - 15

5m = 400

5 is being multiplied so we divide it on both sides.

5m/5 = 400/5
m = 80

We can plug in to prove.

15 + 5(80) = 415

15 + 400 = 415

415 = 415

How many 3-digit even numbers are that begin with either 5 or 6?
mojhsa [17]
Answer: 100 3 digit even number that begin with either 5 or 6

Explanation:
Case 1:
A 3 digit that begin with 5 should be 500-599 so there are 100 numbers
But we are only finding even number
So 100/2 = 50 3-digit even number that begin with 5.

Case 2:
A 3 digit that begin 6 should have
600-699 and there are also 100 number including even and odd in total. Since we are only finding even number we get:
100/2 = 50 3-digit even number that begin with 6.

Plus both case together we get 50 3-digit even number that begin with 5 + 50 3-digit even number that begin with 6= 50 + 50 = 100

A large number of applicants for admission to graduate study in business are given an aptitude test. Scores are normally distrib
DiKsa [7]

Answer:

The fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%

Step-by-step explanation:

Scores are normally distributed with a mean of 460 and a standard deviation of 80. For a value x, the associated z-score is computed as z = \frac{x-460}{80}, therefore, the z-score for 400 is given by z_{0} = (400-460)/80 = -0.75. To compute the fraction of the applicants that we would expect to have a score of 400 or above, we should compute the probability P(Z > -0.75) = 0.7734, i.e., the fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%
