The image of a triangle after it has been dilated with a center at the origin has vertices at A prime(–12, 6), B prime(6, –18), and C prime. If the pre-image of A prime, point A, has coordinates of (–18, 9) and the pre-image of C prime, point C, has coordinates of (18, 12), which statements are true? Check all that apply The coordinates of C prime are (27, 18). The coordinates of C prime are (12, 8). The scale factor is 1.5. The scale factor is 0.75. The scale factor is Two-thirds. The coordinates of B are (9, –27). The coordinates of B are (4, –12).

B,E,F

Step-by-step explanation:

I just took the quiz

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

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.
