<h2>Therefore x=2 and y= 1</h2>

Step-by-step explanation:

Given equations are

$y = 6x -11$ and $-2x -3y = -7$ .........(2)

⇒ $y - 6x = -11$ .......(1)

Equation (2)× 3 - Equation (1)

$-6x -9y -(y-6x) = -21 -(-11)$

⇔ $-6x -9y-y+6x=-21+11$

⇔-10y = -10

⇔y=1

Putting the value of y in equation (1) we get

$1 = 6x -11$

⇔x =2

Therefore x=2 and y= 1

Find the x-intercept and y-intercept of the liné.<br> - 6x + 5y = 21

Hunter-Best [27]

Answer:

x=-3.5 or -7/2 (same thing)

y=21/5

Step-by-step explanation:

x intercept is when y=0

y intercept is when x=0

x intercept is

-6x=21

x=21/-6

x=-3.5

y intercept is

5y=21

y=21/5

The distribution of the test statistic for analysis of variance is the F-distribution. true or false

lubasha [3.4K]

Answer:

True. See explanation below

Step-by-step explanation:

Previous concepts

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"

If we assume that we have $k$ groups and on each group from $j=1,\dots,k$ we have $k$ individuals on each group we can define the following formulas of variation:
