DESPERATE WILL GIVE BRAINLIST AND THANKS

Answer: Positive

Step-by-step explanation:

A scatter plot for speed and distance is created.

We know that distance = speed x time

Hence when speed increases , distance increases and similarly when speed decreases, distance decreases.

Thus if we plot on x axis distance, we find that x increases when y increases.

So we find that there is a strong positive relationship between the two variable

D=tS

where D= distance S=speed and T=time.

Since D varies directly as speed, we have positive relationship.

Hope this helps! :)

Consider kite WXYZ.

Answer:

a = 8; b = 40

Step-by-step explanation:

<em>See attached</em>

<h3>Given </h3>

XY = 3a - 5
YZ = a + 11
∠W = 50°
∠X = 3b
∠Y = 70°

Values of a and b

<h3>Solution</h3>

<u>Since XY and YZ are congruent sides, XY = YZ</u>

3a - 5 = a + 11
3a - a = 11 + 5
2a = 16
a = 8

<u>The angles Z and X are equal and the sum of 4 angles is 360°, therefore:</u>

3b + 3b + 50° + 70° = 360°
6b + 120° = 360°
6b = 240°
b = 40°

<u>Correct option is the last one </u>

a = 8; b = 40°
