Let
x--------> the number of children
y------> the number of teenagers
z------> the number of adults
we know that
------> equation A
-----> equation B
-------> equation C
Substitute equation C in equation A and equation B
![2[\frac{4}{3}y]+3y+5z=1,950](https://tex.z-dn.net/?f=2%5B%5Cfrac%7B4%7D%7B3%7Dy%5D%2B3y%2B5z%3D1%2C950)
--------> equation D
![[\frac{4}{3}y]+y+z=570](https://tex.z-dn.net/?f=%5B%5Cfrac%7B4%7D%7B3%7Dy%5D%2By%2Bz%3D570)
--------> equation E
Multiply equation E by 
--------> equation F
Adds equation D and equation F
therefore
<u>the answer is the option</u>
In order to find the median the 1st thing I would do is put the number in order
80,84,87,88,88,90,90,95,98,100
then cross them out Start with left then go the right and so on...
until you get 1 number in the middle left (Since theirs 2 numbers in the middle add them up and divide by two ) 88+90=178 178/2=89
Median = 89
Now in Order to find the mean add up all the numbers and divide by however many numbers their are
You should get 900 then divide by 10 because their were 10 numbers
So Median=89 & Mean=90
Hi There!
Follow y = mx + b
m = slope
b = y intercept
(a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time?
Slope = 5
Y intercept = 10
(b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.
The rate of change is how much it takes for the amoun to change. The initial amount should be going up with a slope of 5 each time.
(c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.
Start at the origin than continue with a slope of 5 and make sure the y intercept is correctly graphed.
