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
Answer:
100<x<500
Step-by-step explanation:
The third side cannot exceed the others added up so x is less than 500, due to the laws of triangles.
If you subtract 300-200, you get 100, so x has to be greater than 100.
x is greater than 100 but less than 500
Therefore the answer is...
100<X<500
The laws of triangles state that a triangle has to be greater than the other two edges subtracted, and less than the other two edges added.
I hope this helps!!!
Answer:
(or 6)
Step-by-step explanation:
<u>Set f(x)=0:</u>




or 
<u>Now check both solutions:</u>




Therefore,
because there is a hole at
. The denominator, in addition, can never be 0, so the function is undefined for
.





Since
, then
is the only zero of the function.
Answer:
12/20
Step-by-step explanation:
John scored =12 points
His tries =20 tries
Probability = number of favourable outcomes / no. of all possible outcomes
Probability = 12/20
=3/5
