Answer:
77
Step-by-step explanation:
I got it right on my question
4.43
To find the mean (average) # of sick days taken, you add all the numbers, then divide by the number of employees.
31 ÷ 7 = 4.4285714286 or aprox. 4.43
<u>Given</u>:
Given that the graph of the triangle ABC.
The coordinates of the triangle are A(2,-1), B(-1,1) and C(1,-2)
We need to determine the coordinates of the point A after the dilation with a scale factor of 3 centered at the origin.
<u>Coordinates of the point A after dilation:</u>
The general rule for a coordinate to dilate a factor of c from the origin is given by
Thus, applying the above rule, the coordinate A(2,-1) is dilated by a scale factor of 3 about the origin, we get;
Simplifying, we get;
Thus, the coordinates of point A after dilation with a scale factor of 3 centered at the origin is (6,-3)
The diagonals are perpendicular to each other.
The right triangle has half of each diagonal as sides, so the hypotenuse or side length is Sqrt(9^2 + 12^2) = 15.
Hint: a 3,4,5 sided triangle is the smallest integer right triangle. Doubling or tripling, etc. is still a right triangle. So when I saw the 9,12, I knew that 15 was the hypotenuse.
