To find the mean= add all numbers then divide by the amount of numbers there are

25/5=5

So, mean=5

To find the median- order the numbers from least to greatest, then look for the middle number.

2, 5, 5, 6, 7

The middle number is 5, so the median is 5.

To find the mode, look for the most commonly used number. 5 is used twice, which is the most, so 5 is the mode.

To find the range, subtract the smallest number from the largest number.

7-2=5

So, the range is 5.

In summary:

Mean: 5
Median: 5
Mode: 5
Range: 5


Hope this helps! Comment if you have any questions or concerns!

If f(x) is an exponential function where f(4) =17 and f (12.5) = 31, then find the value of f(18.5), to the nearest hundredth.
Svetradugi [14.3K]
Solution: f(18.5)=31.47

Step by step solution:
I started by making an equation in slope intercept form- I found the slope, 28/17, with the points (4, 17) and (12.5, 31). Then I found the y intercept, 1, with the point (4, 17). So the equation is y=28/17x+1. Then I just plugged 18.5 where the x is and solved for y

28/17(18.5)+1=y
28/17(37/2)+1=y
1036/34+1= y
30.47+1=y
y=31.47

Keep in mind that 1036/34 is not exactly 30.47 but that 30.47 was rounded to the nearest hundredth

Hope this helps :)

100 - 68 = 32% discount

Not sure what asking with total price, because tax varies by state.
