ZanzabumX [31]3 years ago
6 0

Answer:

-3

Step-by-step explanation:

For an expression to be undefined,. the denominator must be equal to 0

Therefore, in order to make that expression undefined, we must equate the denominator to 0

6 + 2v = 0

2v = 0 - 6

2v = -6

v = -6/2

v = -3

So in order to make the expression to be equal to 0, v must be -3

mariarad [96]

Answer: c) 81

Step-by-step explanation:

The formula to calculate the degrees of freedom error for a one-way within-subjects ANOVA is given by :-

\text{df}=(n-1)\times(k-1)

Given : A researcher recorded the shooting percentage of 28 professional basketball players in each of four quarters in a game.

Here , n= 28 and k= 4

\text{df}=(28-1)\times(4-1)=27\times3=81

Hence, the degrees of freedom error for a one-way within-subjects ANOVA are 81.

=2*2*2*2*2/ 3*5*43

The length of a rectangle is 2 more than twice the width. The perimeter is 76 feet. Find the length and width of the rectangle.
vlabodo [156]
So we can set x= width
2x+2 = length
so 2(x)+2(2x+2)= 76
so that will give us 2x+4x+4=76
6x=72
x=12
so 12 is width and 26 is length
