Answer:

a. B

b. 4

c. BD

Step-by-step explanation:

a. Point A is at -7; point D is at +1. The distance between these points is ...

1 -(-7) = 8

The midpoint will be 8/2 = 4 units from either end so will be at ...

A +4 = -7 +4 = -3

D -4 = 1 -4 = -3

The point located at -3 is point B, the midpoint of AD.

b. Having done the above calculations, we know that segment AB is 4 units long.

c. We also know that segment BD is 4 units long. That is because the midpoint divides a segment into two equal parts.

Line 'L' is horizontal and passes through (-5,8). Line 'L is vertical and passes through $(4,-1)$. Find the point of intersectio

Elanso [62]

<h3>The two lines intersect at (4,8)</h3>

Every y coordinate on the horizontal line is the same, so each point has a y coordinate of y = 8. This is to be able to pass through (-5,8)

Every x coordinate on the vertical line is the same, so each point has an x coordinate of x = 4. This is to be able to pass through (4,-1)

Put this together to get the answer (x,y) = (4,8)

<u>Answer:</u>

The correct answer option is $\frac { 4 } { 4 9 }$ .

<u>Step-by-step explanation:</u>

We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).

Total number of days in a week = $7$

Number of days in weekend = $2$

Probability of being born on weekend = $\frac { 2 } { 7 }$

P (both parents were born on weekend) = $\frac{2}{7} \times \frac{2}{7}$ = 4/49
