Answer:
Step-by-step explanation:
Given the regression equation :
y=2+3x
Mean of y values ; y = 5.0
Where y is the predicted variable ; x = predictor variable
The predicted value of y for X = 2
Null: H0 = 5
Alternative H1 : ≠ 5
Sample size (n) = 10 pairs
Degree of freedom = n - 2 = 10 - 2 = 8
The answer is B. To find the median you should place the numbers in value order. The middle number will be the median. :
Girls : 73 81 89 91 93
Boys: 68 73 78 86 91
The girl's scores' median is 89
The boy's scores' median is 78
89-78= 11
Answer:
Step-by-step explanation:
If you are asking what 3x2-48 is, then the rules of Pemdas would be relevant in this.
First we would multiply. So, 3 times 2 is 6.
Then, 6-48 is -42
Answer:
Find the slope that passes between the points.
(y₂ - y₁) / (x₂ - x₁)
J(-4, -5)
K(-6, 3)
(3 - (-5)) / (-6 - (-4))
(3 + 5) / (-6 + 4)
8 / -2
-4
Step-by-step explanation:

2 n/3 would be the closest answer although it looks as if the 2 is supposed to be multiplied by n/3 which would lead me to write it as 2(n/3)
