Answer:
the populations from which the samples were drawn have different standard deviations
Step-by-step explanation:
Given that the assumption of homogeneity of variance is the same as the assumption of the independent samples t-test which asserted that all comparison groups possess the same variance
Therefore, if the homogeneity of variance assumption is violated in an independent groups t-test, this means "the populations from which the samples were drawn have different standard deviations."
Answer:
The general equation of a circle is x² + y² - 6x - 16y + 48 = 0
Ok let’s solve it
5(x-2)^2-20=0
first let’s foil (x-2)
5(x^2-4x+4) -20=0
now distribute the 5
5x^2 -20x +20 -20 = 0
combine like terms
5x^2-20x=0
take the gcf
5x(x-4)=0
x=0, 4
solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k
Answer:
that would be 20 lol
Step-by-step explanation:
Answer:
No. of yellow balloons = r - b - 
Step-by-step explanation:
Total number of balloons = r
No of blue balloons = b
Blue balloons are twice the no of green balloons. so
No. of green balloons =
No of yellow balloons = ( Total number of balloons ) - ( No of blue balloons ) - ( No. of green balloons )
⇒ No. of yellow balloons = r - b -
