Answer:
-8.8
Step-by-step explanation:
combine terms on right side of equal sign(50)
know your equation is -5v+6=50
subtract 6 from both sides so you know have -5v=44
then divide both sides by negative five so know you have v=-8.8
(plug in -8.8 to check)
Answer:
B. Yuri divided by n instead of n-1
Step-by-step explanation:
It was stated in the question that the dataset was sample dataset. For a sample dataset, the standard deviation is given by the formula,
σ = √ Σ (Xi - mean)²/(n - 1) where i = 1,2,3.....n
Since this is just a sample dataset and not the whole population, Yuri should have divided by n-1 instead of n.
Answer:
under the 48 is -24
on the right side of 6 is -5
on the right side of 48 is -40
-8w+3z
w=2.2
z=-9.1
-8(2.2)+3(-9.1)
-17.6-27.3
-44.9
The answer is -44.9
