For a set of 5 positive integers, the mean is 4, the mode is 1, and the median is 5. What are the 5 numbers?

Answers

Let the 5 integers be a,b,c,d and e (arranged in ascending order).
Since we know that the median is five, we can conclude that the value of c=5.
It's given that the mode is 1. 1<5, and has to be repeated more than once. Therefore, a and b = 1.
Now, the mean is 4. So, (1+1+5+d+e)=4
d+e=13 (d and e have to be greater than 5)
Which makes d=6 and e=7

In conclusion, the 5 integers are 1,1,5,6,7

At Funland, all rides cost $1. Angela has $21.50. How
many rides can she take?

Answers

She can take 21 rides.

Answer:

She can take 21 rides

Step-by-step explanation:

The best way to solve this problem is to have a number that isn't a decimal. Since she can't take half a ride, and the rides cost one dollar each, subtract 50 cents from 21.50. You'll end up with 21. Divide 21 by 1, and the quotient is 21 rides.
