Step-by-step explanation:

If you look at the green bars that are 11:00-12:59, 9:00-10:59 and 7:00 to 8:59 you will notice they are all under 13, The number of runners that finished it in 11:00-12:59 are 8, The number of runners that finished it in 9:00-10:59 are 6 and The number of runners that finished it in 7:00-8:59 are 2. 8+6+2 = 16

The number of runners who finished in under 13 minutes is 16.

What is a histogram?

A histogram is a representation of the distribution of data with intervals.

We have,

From the histogram,

Number of runners from 7:00 to 8:59 minutes = 2

Number of runners from 9:00 to 10:59 minutes = 6

Number of runners from 11:00 to 12:59 minutes = 8

The number of runners in under 13 minutes.

= 2 + 6 + 8

= 16

Thus,

The number of runners in under 13 minutes is 16.

The missing vertices of the pararllelogram is D(- 4, 0).

What is a parallelogram?

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

We know the diagonals of a parallelogram bisect each other.

Given, Three of the four vertices (corners) of a parallelogram are A(-2,7), B(3,7), and C(2,5) and assuming the fourth vertices is D(x, y).

∴ The midpoint of BD is equal to the midpoint of AC.

Midpoint of a line segment joining the point (x₁, y₁) and (x₂, y₂) is

(x₁ + x₂)/2, (y₁ + y₂)/2.

So, (3 + x)/2, (7 + y)/2 = (-2 + 3)/2, (7 + 7)/2.

(3 + x)/2 = -1/2.

3 + x = - 1.

x = - 4 And,

(7 + y)/2 = 14/2.

7 + y = 7.

y = 0.

So, D(- 4, 0).
