irga5000 [103]

Answer:

|7 - n|

Step-by-step explanation:

Finding a difference means finding what that number is subtracted by another number, and then finding the absolute value of your result.

Assuming "a number" = n, the <u>difference</u><em> </em>of a number and 7 is |7 - n|

A researcher computes the definitional formula for SS, and finds that Σ(x − M) = 44. If this is a sample of 12 scores, then what
olga_2 [115]

Answer:

Option B.

Step-by-step explanation:

Given information:

Σ(x − M) = 44

where, M is mean.

Sample size = 12

The computational formula for sample variance is

s^2=\dfrac{\sum (x-M)^2}{N-1}

where, M is sample mean and N is sample size.

Substitute Σ(x − M) = 44 and N=12 in the above formula.

s^2=\dfrac{44}{12-1}

s^2=\dfrac{44}{11}

s^2=4.0

The sample variance is 4.0.

Therefore, the correct option is B.

Fill in the blanks below.
Crank
The slope for the first one would be:
y2-y1/x2-x1, so replace those with the coordinates and you'll get:
-3-1/-7-(-7) => -4/0 so I guess the slope is zero

the slope for the second one would be:
-3-(-3)/5-(-4)=> 0/9 I think this one would be undefined.
Check to make sure, though!
