Which scatterplot demonstrates the strongest relationship between two quantitative variables?

andreyandreev [35.5K]

The scatterplot demonstrates the strongest relationship is, a graph has x on the x-axis, and y on the y-axis. Points increase loosely together.

<h3>Correlation coefficient of scatterplot</h3>

The correlation coefficient of scatterplot is used to demonstrate the relationship between variables.

When two variables increases together, they are said to have positive correlation.

When one is increasing and another is decreasing, they are said to have negative correlation.

When most of data points form a straight line or lies close to the straight line, it indicates strong linear correlation.

From the given options;

Option A, zero correlation
Option B, less than 1
Option C, 1 or greater than 1
Option D, -1 or less than 1

Thus, the scatterplot demonstrates the strongest relationship between two quantitative variables is option C, "a graph has x on the x-axis, and y on the y-axis. Points increase loosely together".

The complete question is below:

A. A graph has x on the x-axis, and y on the y-axis. Points are scattered throughout the graph.

B. A graph has x on the x-axis, and y on the y-axis. Points curve up and then down in a line.

C. A graph has x on the x-axis, and y on the y-axis. Points increase loosely together.

D. A graph has x on the x-axis, and y on the y-axis. Points decrease loosely together.

Evaluate the numerical value of the vertical velocity of the car at time t=0. 25s using the expression from part d, where y0=0.

Alex73 [517]

The vertical velocity of the car at the given position and time is 4.905 m/s.

The given parameters:

Initial angular velocity, $\omega_0$ = 6.3 rad/s
Time of motion, t = 0.25 s
Vertical displacement, y = 0.75 m
Angular acceleration, $\alpha = 0.95 \ rad/s^2$

<h3>What is vertical velocity?</h3>

This is the linear velocity of an object in a vertical direction.

The angular velocity of an object in a circular motion is given as;

$\omega_f = \omega _0 + \alpha t\\\\\omega _f = 6.3 \ +\ 0.95 \times 0.25 \\\\\omega _f = 6.54 \ rad/s$

The vertical velocity of the car at the given position and time is calculated as follows;

$v = \omega r\\\\v = \omega_f y\\\\v = (6.54 \ rad/s)\times (0.75\ m)\\\\v = 4.905 \ m/s$

Thus, the vertical velocity of the car at the given position and time is 4.905 m/s.

lions [1.4K]

Answer:

262.50-3000=222.50

therefore 3000×100/222.50×3.5=$4,719
