Answer:
r = 1/2(s -t/x)
Step-by-step explanation:
Here, we simply want to make r the subject of the formula;
We proceed as follows;
s = 2r + t/x
s - t/x = 2r
Divide both sides by 2
r = 1/2(s - t/x)
There are 60 skittles in each goodie bag.
Step-by-step explanation:
Given,
The ratio of m&m's to skittles = 1:3
Total number of candies = 80
Let,
x be the original number to be multiplied with ratio, therefore;
Number of m&m's = 1x
Number of skittles = 3x
Dividing both sides by 4
Number of skittles = 3x = 3(20) = 60
There are 60 skittles in each goodie bag.

Okay, so slope intercept form is y=mx+b. Like a normal problem with numbers, you add or subtract from each side.
3x-2y= -16
you want to leave the y by itsself, so your going to add 3x to 16, but write it out how the formula is (y=mx+b). now, you should have -2y= -3x-16. (the three is now negative because you moved it to the other side of the equation.)
now, remember that you want the y all by itself, so, all you have to do now is divide.
-2y= -3x-16 ---------- now is y= -3/-2x minus 16/-2. (those are now fractions, but the y is alone.) now you simplify.
-3/-2x is already simplified, but 16/-2 is not so it changes into -8,after dividing the fraction.
now you have the answer.
y= -3/2x-8x (it is the same as the formula now!)
hope this helps! it was hard to explain through typing but if you read it carefully, i explained every step.
Answer:
True
Step-by-step explanation:
Residual standard deviation is the square root of the residual variance. It is an estimate of the error made on the measurement of the dependent variable.
Thus, the spread around the regression model is usually measured with the residual standard deviation because it is the measurement of standard error between actual and predicted value.
