We are given the following relation:
y = 4.302 x – 3.293
To solve for the mean value of y when x = 20, what we have
to do is to find for the value of y at x = 20 and the value of y at x = 0. Then
we get the average of the two values.
when x = 0
y(0) = 4.302 (0) – 3.293
y(0) = - 3.293
when x = 20
y(20) = 4.302 (20) – 3.293
y(20) = 82.747
The mean value would be:
mean y = [y(20) + y(0)] / [20 + 0]
mean y = [82.747 + (-3.293)] / 20
<span>mean y = 3.9727 = 3.97</span>
Its the same as 250 you just have to multiply ×10
2 groups of 4 people can answer the different phone lines and 2 people will be leftover.
Answer: concave hexagon
Step-by-step explanation:
Concave polygons have diagonals that are outside of the polygon. In a convex polygon, all the diagonals are inside, so we know it can’t be convex.
Hexagons have six sides, while pentagons have five sides, so it must be a hexagon.
So, concave hexagon is correct or choice 3
