Perimeter of the triangle, a+b+c
In this case, a=b=c=28
So, perimeter would be 28*3 = 84 cm
Slope is easy you can look that up and the y- intercept is the point of the y axis
The answer is
D.wear the proper safety gear like goggles and gloves.
The mean absolute deviation is given by the next formula:
Where n is the number of points in the data set and x with a bar on top is the mean.
In our case,
and n=25.
Then,
Finally,
The answer is 1.4 once rounded.
