Answer:

If a scatter plot has no association, its values are random and there is no line of best fit that can be drawn.

Step-by-step explanation:

When we talk about association, we are asking if there is a relationship between two variables. If I change one thing, will the other change in a predictable way? When there is no association, there isn't a relationship between the two variables.

Scatter plots show the raw data values, and maps them onto a graph. When there is a relationship between two values, we can see it, because some kind of shape forms on the graph.

In the picture below, we see that there is still a relationship when there is a non-linear (not straight) relationship between two variables. But when there is no association, there is no relationship (or at least not a predictable one).

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

$x + 2 = \frac{x}{4} + 5$

Multiply through by 4 to eliminate the fraction

That's

$4x + 8 = \frac{x}{4} \times 5 + 5 \times 4 \\ 4x + 8 = x + 20$

<u>Subtract x from each side</u>

That's

$4x - x + 8 = x - x + 20 \\ 3x + 8 = 20$

<u>Subtract 8 from each side</u>

$3x + 8 - 8 = 20 - 8 \\ 3x = 12$

<u>Divide both sides by 3</u>

$\frac{3x}{3} = \frac{12}{3}$

We have the final answer as

<h3>x = 4</h3>

Hope this helps you

(a) The vertical motion equation for the ball is h = 8 + 48t - 16t².

(b) The time for the ball to hit the ground is 3.15 s.

(c) The time for the ball to travel 56 ft above the ground is 0.79 s.

<h3>Vertical motion equation for the ball</h3>

The vertical motion equation for the ball is calculated as follows;

h = h₀ + vt - ¹/₂gt²

h = 8 + 48t - ¹/₂(32)t²

h = 8 + 48t - 16t²

<h3>Time for the ball to hit the ground</h3>

0 = 8 + 48t - 16t²

solve the above quadratic equation with formula method;

a = -16, b = 48, c = 8

t = 3.15 s

<h3>Time for the ball to be 56 ft above the ground</h3>

let upward motion be positive

h = 8 + 48t + 16t²

56 = 8 + 48t + 16t²

0 = -48 + 48t + 16t²

solve the above quadratic equation with formula method;

a = 16, b = 48, c = -48

t = 0.79 s

Solve for the distance between (13,55) and (61,22). Round your answer to the nearest hundredth.

Neporo4naja [7]

Answer:

Step-by-step explanation:

position 1: (13,55)

position 2: (61,22)

distance = $\sqrt{(p_{x2}-p_{x1})^{2} + (p_{y2}-p_{y1} )^{2}}$

distance = $\sqrt{(61-13)^{2} + (22-55)^{2}}$

distance = $\sqrt{(48^{2} + (-33)^{2} }$

distance = $\sqrt{2304 + 1089}$

distance = $\sqrt{3393}$

distance = 58.25
