Step-by-step explanation:
given that the Paralyzed Veterans of America recently sent letters to a random sample of 100,000 potential donors and received 4781 donations

(left tailed test)
Sample proportion = 
p difference = -0.00219
Assuming H0 to be true, std error of proportion
=
Test statistic Z = p diff/std error = -1.38641
p value = 0.0828
since p value >0.05 our significance level
we accept null hypothesis
There is no statistical evidence of a real drop in the contribution rate.
In this case we use intersecting secant theorem
According to this theorem, GF*GE = GH*GA
So,we plug in the values
(x-3)*(x-3+9) =(x-2)*(x-2+6)
(x-3)*(x+6) =(x-2)*(x+4)
x^2 +6x -3x -18 =x^2 +4x -2x -8
x^2 +3x -18 =x^2 +2x -8
x^2 +3x -18 -x^2 -2x +8 =0
x -10 =0
x=10
So,FG =x-3 = 10-3 =7
Answer:
The Ratios are Proportional
Step-by-step explanation:
Let,
R1 = 48 / 72 ----- (1)
R2 = 6/9 ------ (2)
If we divide right hand side of above equation by 8, we get,

Therefore, it means that, in simplified form, both ratios are same and hence proportional.
R1 : R2 = 6/9 : 6/9
