I think the correct answer is 27
Im pretty sure the answer is 3+4x
How its solved:
(4x2+6x+5)-(3x2+2x+4)
(8+6x+5)-(6+2x+4)
(13+6x)-(10+2x)
13+6x-10-2x
3+4x
The distance between point M and point is is about 8.06 units (rounded to nearest hundredth)
Answer:
φ = 0.34
Step-by-step explanation:
Given:
total number of observations = N = 100
chi-square test for independence χ2 = (4, N = 100) = 11.73
To find:
phi coefficient φ
Solution:
phi coefficient φ is computed as:
φ = √( χ2 / n )
= √ (11.73 / 100 )
= √0.1173
φ = 0.3425
