7. Three vertices of a parallelogram are (0, 0), (−4,0) and (0, 5). Find all 3 possible coordinates for

kenny6666 [7]

The given vertices combine with the fourth vertex as follows;

a) Coordinates; (-4, 5)

Lengths of the sides; 4 and 5

b) Coordinates; (4, 5)

Lengths of the sides; 4 and √41

c) Coordinates; (-4, -5)

Lengths of the sides; 5 and √41

<h3>How can the vertex coordinates be found?</h3>

The given vertices are;

(0, 0): The origin

(-4, 0): 4 units to the left of the origin along the abscissa

(0, 5): 5 units above the origin, along the ordinate

a) The point that forms a rectangle is above the point (-4, 0) and to the left of the point (0, 5), which gives;

The coordinates of the point that forms a rectangle is the point (-4, 5)

The lengths of the sides are;

0 - (-4) = 4

5 - 0 = 5

b) The first parallelogram is formed by moving an equal distance of the point (-4, 0) from the origin from the point (0, 5), which gives;

The first parallelogram is formed by the point (4, 5)

The lengths of the sides are;

4 - 0 = 4
√((5 - 0)^2 + (4 - 0)^2) = √41

c) The second parallelogram is formed by the moving an equal distance of the point (0, 5) from the origin from the point (-4, 0), which gives;

The second parallelogram is formed by the point (-4, -5)

The lengths of the sides are;

(5 - (-5)) = 5 and √41

Suppose that the regression for predicting weight (in pounds) from Height (in Select one answer inches) is given by Weight =-115

Nutka1998 [239]

Answer:

Option D) I and II only

Step-by-step explanation:

We are given the following in the question:

Regression equation:

$w = -115 + 3.6h$

where w is the weight in pounds and h is the height in inches.

Since the weight depends on height, height becomes the independent variable and weight becomes the dependent variable.

I. A person who is 61 inches tall will weigh 104.6 pounds

When h = 61,

$w = -115 + 3.6(61) = 104.6$

Thus, the given statement is true.

II. For every additional inch of height, the predicted weight will increase, on average, by 3.6 pounds.

If the height increases by 1 unit, then,

$w(h+1) - w(h) = -115 + 3.6(h+1) - (-115 + 3.6(h))\\w(h+1) - w(h) = 3.6(h+1-h)\\w(h+1) - w(h) = 3.6$

Thus, the given statement is correct.

III. The correlation between weight and height is negative.

No, the given statement is not correct as with increase in height the weight increases and with decrease in height the weight decreases.

Thus, the correct answer is

Option D) I and II only
