A 360 degree rotation, around any point. Now sometimes you can do it with 180 degrees of rotation, but I need more information to specify.

The simplified form of the expression is given as 83x/56 -(97/105)
<h3>Finding the value of unknown variables</h3>
Alphabets are usually represented as unknown variables in a equation or expression.
Given the following expression shown below
6/7 x -2/3 + 3/5 + 5/8 x -6/7
Collect the like terms to have;
6/7 x+ 5/8 x -2/3 + 3/5 -6/7
Simplify
48x+35x/56 - (70-63 + 90)/105
The final expression will be given as;
83x/56 -(97/105)
Hence the simplified form of the expression is given as 83x/56 -(97/105)

Answer:
Therefore the variance on the data set is 8.3
Step-by-step explanation:
In order to find the variance of the set of data we first need to calculate the mean of the set, which is given by:
mean = sum of each element / number of elements
mean = (5 + 8 + 2 + 9 + 4)/5 = 5.6
We can now find the variance by applying the following formula:
So applying the data from the problem we have:
s² = [(5 - 5.6)² + (8 - 5.6)² + (2 - 5.6)² + (9 - 5.6)² + (4 - 5.6)²]/(5 - 1)
s² = [(-0.6)² + (2.4)² + (-3.6)² + (3.4)² + (-1.6)²]/4
s² = [0.36 + 5.76 + 12.96 + 11.56 + 2.56]/4 = 8.3
Therefore the variance on the data set is 8.3
Step-by-step explanation:
the slope is always the factor of x.
in slope intercept form, as well as here in point slope form.
the important thing is that the y term is just brought to a simple positive y form (and not cy with c is different than 1).
and then, what you see on the other side as factor is x is the slope.
here : -7
the other numbers in the equating are irrelevant for the slope. they determine the "offset" of the line from (0, 0).
Step-by-step explanation:
Apples cost four times as much as oranges per pound.
If the cost of orange =x
then, cost of apples =4x
But,
the costs of apples =2.80$
So,4x=2.80
⠀
⠀
so,oranges costs for per pound =0.70$
