Count be ten for the y axis
Hi there!
Evaluate f(x) at x = 2 by substituting 2 for x:
f(x) = 3x - 4
f(2) = 3(2) - 4
f(2) = 6 - 4
f(2) = 2
Answer:
The temp. rose by 9.5 degrees because 66.5-57.0=9.5
Hope this helps
Answer:
you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points
Answer: B) 0.28
Step-by-step explanation:
Given that:
Lean/Healthy Overweight/ ObeseSelf Esteem Low 18 32 High 32 18
Overweight/Obese Lean/Healthy Total
Low 32 18 50
High 18 32 50
Total 50 50 100
the phi correlation coefficient is defined by Ф = √x²/n
where n = 100 ( total number of response )
x² = [(32×32 - 18×18)² × 100] / [50 × 50 × 50 × 50]
Ф = √ [(700)² x 100) / (50)⁴ × 100
Ф = 700 / 50²
Ф = 0.28
Therefore option B) is the correct answer
