Do the multiplication both sides,
Arrange the terms to LHS according to their variables,
Factorise this polynomial
So what we notice here is when you're multiplying two numbers you're getting 0 as answer.
So one of them must be 0.
If (x-1) is 0
then x = 1
similarly,
x-6=0
then, x= 6.
So the possible values of x are 1 and 6.
Step-by-step explanation:
Regression analysis is used to infer about the relationship between two or more variables.
The line of best fit is a straight line representing the regression equation on a scatter plot. The may pass through either some point or all points or none of the points.
<u>Method 1:</u>
Using regression analysis the line of best fit is:
Here <em>α </em>= intercept, <em>β</em> = slope and <em>e</em> = error.
The formula to compute the intercept is:
Here<em> </em> and
are mean of the <em>y</em> and <em>x</em> values respectively.
The formula to compute the slope is:
And the formula to compute the error is:
<u>Method 2:</u>
The regression line can be determined using the descriptive statistics mean, standard deviation and correlation.
The equation of the line of best fit is:
Here <em>r</em> = correlation coefficient =
and
are standard deviation of <em>x</em> and <em>y</em> respectively.
Answer: List of the angles from smallest to largest are C, B and A
Step-by-step explanation:
The diagram of triangle ABC is shown in the attached photo. Since none of the sides are equal, then it is a scalene triangle.
From the information given,
AB = m – 2
BC = m + 4
AC = m
It means that the longest side is BC, the medium side is AC and the shortest side is AB. Therefore,
The smallest angle is angle C.
The medium angle is angle B.
The largest angle is angle A
