Answer:
Hamburger=31%
Pie=47%
Hot Dog=22%
36=100%
Step-by-step explanation:
What you do is you take the number of how many people have taken the survey and put it over 36.
11/36, 17/36, 8/36=
Hamburger=31%
Pie=47%
Hot Dog=22%
36=100%
Answer:
10.75
Step-by-step explanation:
To get the average, we always SUM UP all the numbers and divide by the number of numbers.
We do this for "change" row since we want average of "change".
Let's add up all the changes:
11 + 12 + 10 + 10 + 11 + 10 + 11 = 75
How many numbers are there?
There are 7 numbers
Now, the average:
Average = Sum/Number of Numbers
Average = 
The average = 10.75
I believe it's a linear function I could be totally wrong math isn't my strongest subject.
Answer:
Rule #4
Step-by-step explanation:
'Im' needs an apostrophe because it is a contraction I'm means I am
Answer:
Here we have the function:
S(t) = 500 - 400*t^(-1)
Then the rate of change at the value t, will be:
S'(t) = dS(t)/dt
This differentiation will be:
S'(t) = -400/t^2
Then:
a) the rate of change at t = 1 is:
S'(1) = -400/1^2 = -400
The rate of change after one year is -400
b) t = 10
S'(10) = -400/10^2 = -400/100 = -4
The rate of change after 10 years is -4, it reduced as the years passed, as expected.
