We could solve for x, but notice that the same expression is being squared in both (x+1)
if (x+1)^2 - 3 = 22 then
(x+1)^2 = 25
that would mean that (x+1)^2 - 5 = 25 - 5 = 20
Answer: No, the normal curve cannot be used.
Step-by-step explanation:
The theorem of the Normal approximation states that if X is B(n,p) then for large n X is N(np, np(1-p)).
The accuracy of this approximation is good
i. for n > [10/p(1-p)]
ii. p is close to 1/2
Hence given p= 4% = 0.04,
q = 1 - 0.04 = 0.96
Let N = [10/p(1-p)]
We find N = 10/p(1-p) = 10/(0.04× 0.96)
N ~= 260
Since n < 260 and p < 0.5
The approximation is not a good one
Step-by-step explanation:
Circumference of the Circle with radius 4. =2πr=2π×4. Central angle that intercepts arc of length 10.8 =10.82π×4×2π =10.8 4
Answer:
1, -14
Just calculate the difference module between the midpoints and the endpoints(2,6) and add the same value to the opposite side.
hope this helps.
