Answer:
Step-by-step explanation:
How to calculate the mean absolute deviation:
<u>Step 1:</u> Calculate the mean.
<u>Step 2:</u> Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.
<u>Step 3:</u> Add those deviations together.
<u>Step 4:</u> Divide the sum by the number of data points.
1. analyze data presented
It is not d because it is not greater than 80 degrees
it is not a because it is clearly not 10 degrees
making system of equations
8x+(4x+60)=180
addition
12x+60=180
move sixty to the other side
12x=120
division
x=10
Angle BEC=*x, so 8x=80
Answer: 80 degrees
The answers are 0 and 2
This can be found by looking at the x axis and finding every point where the line crosses
To find the constant proportionality you would need to find the cost of one ticket which would be 9 dollars
Y=(x×5+41) where the x is number of dogs he has walked. And the y is money he has made
