g which of the following is the most effective way to describe multivariate relationships? group of answer choices schedules graphs equations schedules and graphs
The most effective way to describe multivariate relationships is by means of graphs and multiple variables.
The term "multivariate analysis" refers to a broad variety of statistical methods, not simply one particular approach. These methods enable you to comprehend your data more thoroughly in light of particular commercial or real-world settings.
Multivariate analysis is therefore a key idea to understand if you're wanting to be a data analyst or data scientist.
The breadth of knowledge that multivariate analysis offers is its one key benefit. The insights you find are far more applicable to the actual world because you're drawing a lot more thorough picture of what's happening when you explore numerous factors.
There are two different kinds of multivariate analytic techniques: interdependence techniques, which examine the structure of a dataset, and dependency techniques, which examine the cause-and-effect interactions between variables.

Kylie reads about two popular cell phone apps one app uses 1/2 of a phones storage space the other app uses 5/12 of a phone storage space Explain how Kylie can find the difference in the two storage space of the two apps without drawing a visual model
Answer:
5/12 phone uses less storage space
Step-by-step explanation:
Find a common denominator so you can compare the fractions easily. Use 12.
1/2 = 6/12
5/12 < 6/12, so now you can see that the phone that uses 5/12 of storage space uses less than the one that uses 1/2
You have averaged a score of 150 in the previous 12 bowling games and just bowled a 156. What score do you have to bowl in the next game to have an average of 152?

I need to score 172 in the 14th game to have an average of 152 in 14 games.
What is the weighted average?When the average is not of any individual rather it is an average of two or more groups or sets it is called a weighted average.
To obtain the weighted average we multiply no. of individuals by their averages and sum the next group in the previous procedure and divide them by the total no. of individuals.
The total score of 12 games is (12×150) = 1800.
Again I scored 156 is the 13th game.
Let I score 'x' in the 14th game.
∴ (1800 + 156 + x)/12 + 1 + 1 = 152.
(1800 + 156 + x)/14 = 152.
(1956 + x)/14 = 152.
1956 + x = 2128.
x = 2128 - 1956.
x = 172.
So, I need to score 172 in order to have an average of 152 for 14 games.

what are the coordinates of the centroid of ABC with vertices A (-3, 1), B (-2, 4), and C (5, -2)
Answer:
(0, 1/3)
Step-by-step explanation:
To find the centroid of a triangle with vertices A, B, and C, we can use the following formula:
centroid = (x1 + x2 + x3) / 3, (y1 + y2 + y3) / 3
where (x1, y1), (x2, y2), and (x3, y3) are the coordinates of the vertices A, B, and C, respectively.
In this case, we have A = (-3, 1), B = (-2, 4), and C = (5, -2), so the centroid of the triangle is:
centroid = ((-3) + (-2) + 5) / 3, (1 + 4 + (-2)) / 3 = (0, 1/3)
Therefore, the coordinates of the centroid of ABC are (0, 1/3).

The slope intercept form of equation of required line is
[tex]y = \frac{2}{3}x - 2[/tex]
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan\theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
Slope of the required line = [tex]\frac{2}{3}[/tex]
The line passes through (0, -2)
Equation of the required line =

How to Graph y-2=2/3(x+4)
Answer:
Step-by-step explanation:
To graph the equation y-2=2/3(x+4), you can follow these steps:
Begin by isolating the y term on one side of the equation. To do this, you can add 2 to both sides of the equation:
y-2+2=2/3(x+4)+2
y=2/3(x+4)+2
Next, you can simplify the right side of the equation by multiplying 2/3 by (x+4):
y=2/3(x+4)+2
y=(2/3)x+(2/3)4+2
y=(2/3)x+8/3+2
y=(2/3)x+14/3
This is the standard form of the equation y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is m=2/3 and the y-intercept is b=14/3.
To graph the equation, you can use the slope and y-intercept to plot the first point on the graph. The y-intercept is the point where the graph crosses the y-axis, so you can plot the point (0,14/3) on the graph.
From this point, you can use the slope to find the next point on the graph. The slope is the change in y over the change in x, so you can use the slope to find the change in y and the change in x between two points on the graph. For example, you could choose a point that is 1 unit to the right of the y-intercept, or (1,0). The change in y between these two points is (14/3)-0=14/3 and the change in x is 1-0=1. Using the slope, you can find the y-coordinate of the next point on the graph:
y2=y1+m(x2-x1)
y2=14/3+2/3(1-0)
y2=14/3+2/3
y2=20/3
You can repeat this process to plot additional points on the graph. For example, you could choose a point that is 2 units to the right of the y-intercept

an aircraft is climbing at 30° angle to the horizontal how fast is the aircraft gaining alitude if it’s speed is 500 mph
The speed rate at which the aircraft is gaining altitude is;
dx/dt = 250 miles per hour
Since the aircraft is climbing at 30° to the horizontal. it means there will be a vertical component which will be the altitude and also a horizontal component which will be the horizontal distance covered. while the hypotenuse will be how far it has climbed.
Let us call the vertical component x and the hypotenuse component z.
Thus, from trigonometric ratios, we can say that;
sin 30 = x/z
We are looking for how fast the aircraft is gaining altitude. Thus, using Liebniz notation, we can say this rate is; dx/dt. Thus;
sin 30 = (dx/dt)/(dz/dt)
0.5 = (dx/dt)/(dz/dt)
0.5 × (dz/dt) = dx/dt
Its' speed is 500 mph. This means dz/dt = 500
Thus;
dx/dt = 0.5 × 500
dx/dt = 250 mph
Hence, the speed rate at which the aircraft is gaining altitude is;
dx/dt = 250 miles per hour

What is the equation of the circle with center (-4, -1) and radius 3?
The equation of the circle for all the given values is obtained as x² + y² + 8x + 2y + 8 = 0.
How to write an equation for a circle?The equation for a circle can be written by knowing the coordinates of its centre and the length of its radius.
Since the radius is the distance from the centre to a point on the circle, the equation can be written by distance formula as s (x - h)² + (y - k)² = r² where (h, k) is the coordinate of the centre.
The coordinates of the centre of the circle is given as (-4, -1).
And, the radius is 3.
The general equation of the circle for centre at (h, k) and radius r is given as (x - h)² + (y - k)² = r².
Substitute the corresponding values to obtain,
(x - h)² + (y - k)² = r²
=> (x - (-4))² + (y - (-1))² = 3²
=> (x + 4)² + (y + 1)² = 9
=> x² + 8x + 16 + y² + 2y + 1 = 9
