What is the midpoint of the line segment with endpoints ( 3.5,2.2) and (1.5,-4.8)?
Fantom [35]

Answer:

Option A) (2.5,-1.3) is correct

The midpoint of the given line segment is M=(2.5,-1.3)

Step-by-step explanation:

Given that the line segment with end points (3.5, 2.2) and (1.5, -4.8)

To find the mid point of these endpoints midpoint formula is M=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)

Let (x_1,y_1) be the point (3.5, 2.2) and (x_2, y_2) be the point (1.5, -4.8)

substituting the points in the formula

M=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)

M=\left(\frac{3.5+1.5}{2}, \frac{2.2-4.8}{2}\right)

=\left(\frac{5}{2}, \frac{-2.6}{2}\right)

=\left(2.5,-1.3\right)

Therefore M=(2.5,-1.3)

The midpoint of the given line segment is M=(2.5,-1.3)

Help me it's algebra and dont tell me to look at the lesson :)

Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.

He's supposed to use a total of between 70 and 74 beads, so

70 ≤ b + g ≤ 74

The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so

1.4 ≤ g/b ≤ 1.6

For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions

b ≥ 0

g ≥ 0

(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)

zheka24 [161]

Answer:

<u>It's expected that Jason make 16 out of 20 free throws</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Jason's free-throw scoring average = 80%

2. In a recent game Jason attempted 20 free throws. How many free throws would you expect him to make?

Free throws expected to make by Jason = 20 * 80%

<u>Free throws expected to make by Jason = 16</u>
