Use the formulas below to find the line of best fit for the given data set. write your answer in the form y = mx + b, where m and b are decimals, rounded to the nearest hundredth, if necessary. and , where n = the number of points s = the sum of the products = x1y1 + x2y2 + … + xnyn t = the sum of the x-values = x1 + x2 + … + xn u = the sum of the y-values = y1 + y2 + … + yn v = the sum of the squares of the x-values = x12 + x22 + … + xn2

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
