Answer:
(0,-8/3)
Step-by-step explanation:
2x-3y=8
x-3y=8
Multiply the second equation by -1 and add together
2x-3y=8
-x+3y=-8
---------------------
x +0y =0
x=0
Now we can find y
2x -3y =8
0-3y =8
Divide by -3
-3y/-3 = 8/-3
y = -8/3
(0,-8/3)
The we should use ANOVA instead of several t-tests to evaluate the differences in the mean of three or more groups.
<h3>What is t test?</h3>
A t- test is a measurable test that is utilized to look at the method for two gatherings. It is many times utilized in speculation testing to decide if a cycle or treatment really meaningfully affects the number of inhabitants in interest, or whether two gatherings are not quite the same as each other.
<h3>Explain ANOVA test:</h3>
The ANOVA test permits an examination of multiple gatherings simultaneously to decide if a relationship exists between them.
<h3 /><h3>According to question:</h3>
We ought to utilize ANOVA rather than a few t-tests to assess the distinctions in the mean of at least three gatherings on the grounds that without fail, we direct a t-test (between two gatherings) there is some opportunity that a Kind I blunder is being made while doing the test.

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:
b
Step-by-step explanation:
because if you did the math right it would come out to that
Answer:
1
Step-by-step explanation:
This is a U shaped graph, so the shape is a parabola
Eccentricity of any parabola is 1.
