Turn the word problem into a fraction
4/5
Turn the fraction into a division problem.
4 divided by 5
Turn the division problem into a decimal.
4 divided by 5 = 0.8
Multiply by 100 to turn it into a percent.
0.8 * 100 = 80%

Answer:
Follows are the solution is this query:
Step-by-step explanation:
In point a:
The explicatory variable mostly on X-axis is obtained only at the two-dimensional level or the Y-axis dependent variables, instead of catching the information, they also get diffusion plotted in the attached file please find it.
In point b:
Draw on the scatter diagram as just below the minimum-square correlation axis, which is defined in the attached file please find it.
In point c:
From the plot above, a positive relationship among even in the analysis of bone density, the dominant and non-dominant Arm. They can forecast its bone using bone density throughout the non-dominant arm and the Dominant arm power. They can conclude from the slopes of its regression model, which is inside a non-dominant arm, each unit raises bone strength by 0.936 throughout the dominant atm.
The coordinates of the vertex are (3, -13) and the axis of symmetry is at x = 3.
We can find the vertex by using the formula for finding x-coordinates. The formula for the x-coordinate of a vertex is below.
-b/2a
In this equation, a is the coefficient of the x^2 term (1) and b is the coefficient of the x term (-6). Then we can plug in to find the x term.
-(-6)/2(1)
6/2
3
Now that we have this term, we can plug it in for all values of x to find the y term.
x^2 - 6x - 4
3^2 - 6(3) - 4
9 - 18 - 4
-13
Now we know that the vertex is at (3, -13). Now finding the axis of symmetry is easy because the axis of symmetry in any quadratic is simply x = [x-coordinate of vertex]. So in this case it would be x = 3.

Step-by-step explanation:
Step-by-step explanation:
If there are 15 red marbles, there'll be 7 blue marbles.
If there are 7 blue marbles, there'll be 3 green marbles.
If we get 2 blue marbles and put 2 green, than things will stay like this:
If there are 5 blue marbles, there'll be 5 green marbles.
If we get 2 green marbles and put 2 green, than things will stay like this:
If there are 7 blue marbles, there'll be 3 green marbles.
