hope this helps :-)
Null hypothesis is basically: there is no difference between two characteristics.
So in this case H(0) or null hypothesis is:
No difference in femininity based on contrast between eye color and skin tone.
Alternative hypothesis or H(a) basically contradicts that, so in this case:
There is observed difference in femininity based on contrast between eye color and skin tone.
Answer:
Step-by-step explanation:
The professional soccer player buys 16 acres of land.
He wants to use of the land to put his own soccer field and facility on.
All we have to do is find of 16 acres.
of 16 acres:
* 16 = 4 acres
He will need 4 acres out of the 16 acres for his soccer field and facility.
Answer:
Equation of the circle (x-3)²+(y-5)²=(6.4)²
x² -6x +9 +y² -10y +25 = 40.96
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given endpoints of diameter P(−2, 1) and Q(8, 9)
Centre of circle = midpoint of diameter
Centre =
Centre (h, k) = (3 , 5)
<u><em>Step(ii):-</em></u>
The distance of two end points
PQ =
PQ = √164 = 12.8
Diameter d = 2r
radius r = d/2
Radius r = 6.4
<u><em>Final answer:-</em></u>
Equation of the circle
(x-h)²+(y-k)² = r²
(x-3)²+(y-5)²=(6.4)²
x² -6x +9 +y² -10y +25 = 40.96
x² -6x +y² -10y = 40.96-34
x² -6x +y² -10y -7= 0
