since

6 = 2 * 3 <--- two factors

8 = 2 * 2 * 2 <--- three factors

and since the "2" is there on each, then we can just use that instance of it once.

so instead of using 2 * 3 * 2 * 2 * 2, we'll use 2 * 3 * 2 * 2, and that is our LCD.

2 * 3 * 2 * 2 = 24.

If the correlation coefficient is 0.654, what is the explained variation? (give answer as a percent)

zaharov [31]

Answer:

42.7%

Step-by-step explanation:

Correlation is a statistical measure of inter relationship between two variables' co movement.

Correlation coefficient denotes the direction & extent by which two variables' (same or opposite) movement is linked to each other.

Coefficient of determination = r^2 symbolises percentage of variation in one variable, that can be explained by variation in other variable.

So, in this case r^2 = (0.654)^2 = 0.427716 ; Hence approx 42.7% variation in one variable can be explained by variation in other.

write an algebraic expression that can be used to find the area of a triangle that has a base of 5 units and a height of x units

Musya8 [376]

V=1/3 x 3.14 x r^2 x H
v=1/3 x 3.14 x 2.5^2 x H
v=1/3 x 3.14 x 6.25 x H
v=1/3 x 19.625 x H
1 x 19.625= 19.625 x 58.875 divide 58.875 by 3 = 19.625
1 3
19.625 = Height

Sandy drove 55 miles per hour to Orlando. Write a function rule that relates the number of miles traveled to the hours driven.

zloy xaker [14]

The function rule that relates the number of miles traveled to the hours driven is d = 55t

<h3>What is speed?</h3>

Speed is the ratio of distance traveled by a body to the time taken.

The formula for calculating distance is expressed as:

distance = speed * time

Speed s = d/t

Given that the speed is 55 miles per hour

55 = d/t

Cross multiply

d = 55t

Hence the function rule that relates the number of miles traveled to the hours driven is d = 55t

How do I find the perimeter of a polygon?

noname [10]

Add up the lengths of the several sides of the polygon.

Examples: The perimeter of a triangle is the sum of the lengths of the 3 sides.

The perimeter of a hexagon is the sum of the lengths of the 6 sides.

And so on.

I highly recommend drawing any polygon whose perimeter you wish to calculate.
