Answer:
0.142
Step-by-step explanation:
From the question, we identify the following parameters;
n = 49
p = 82% = 82/100 = 0.82
alpha, α = 1-0.99 = 0.01
Zα/2 = Z_0.005 = 2.575
margin of error = Zα/2 * √( p(1-p)/n)
Margin of error = 2.575 * √(0.82)(1-0.82)/49
Margin of error =0.1416005 which is approximately 0.142
Answer:
Step-by-step explanation:
im not 100% sure but i think it is $2-a
the two number between 21.023 and 21.024 are the following:
21.0234 and 21.0235
The general equation of the ellipse is

where (h,k) the coordinates of the center
a and b represents half the length of the axes
given: center of the ellipse = (0,0)
<span>vertex (-5 , 0) and co-vertex (0 , -3)
</span>
∴ (h,k) = (0,0)
∴ a = 5 and b = 3
So, <span>The equation in standard form of the ellipse is
