Answer:
70
Step-by-step explanation:
69.65
We look at the tenths place to determine if we round up or leave it alone
.6 is greater then or equal to five so we need to round the 9 up
69.65 rounds to 70
Hi!
First, find the median of the original data set.
Arrange the numbers in order,
2, 2, 4, 6, 7, 8, 18, 20, 24
Then find the middle number.
2, 2, 4, 6, 7, 8, 18, 20, 24
Now add the number 10.
2, 2, 4, 6, 7, 8, 10, 18, 20, 24
Find the new middle number.
2, 2, 4, 6, 7, 8, 10, 18, 20, 24
7.5
The first median was 7, the new one is 7.5.
The median increases by 0.5.
Hope this helps! :)

Answer:
30 belongs to the set of real numbers, the set of rational numbers, the set of whole numbers, the set of natural numbers and the set of integers.
Step-by-step explanation:
Answer:
Part a) 
Part b) The total cost is 
Part c) see the explanation
Step-by-step explanation:
Part a) Write a linear equation to represent this situation
Define the variables
Let
x ----> the number of hours
y ----> the total cost in dollars
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or the unit rate
b is the y-intercept or initial value (value of y when the value of x is equal to zero)
In this problem we have that
The unit rate or slope is equal to

The y-intercept or initial value is equal to

substitute

Part b) Use the equation to find the total cost to rent skis from 8:30 am to 3:00 pm
Remember that
3:00 pm=15:00
so
from 8:30 am to 3:00 pm, the total hours is equal to
15:00 -8:30=6:30=6.5 h
For x=6.5 h
substitute in the linear equation and solve for y

Part c) What does your answer mean in context of the problem?
we have that
y=220.25
That means -----> The total cost to rent skis for 6.5 hours is equal to $220.25
