Answer:
The answer is 8%
From the given information, the sample proportion is 18% and a margin of error is 4 percent.
Then, a 90% confidence interval to estimate the population proportion is
(18 +/- 4)
(18-4, 18+4)
(14%, 22%)
22-14 = 8
Answer:
40
Step-by-step explanation:
(2x+1/(2x))^5 *(2x -1/(2x))^5
= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2
= (4x^2-1/4(x)^2)^5
now
x =4x^2. ,a = 1/4(x)^2 ,n =5
we have
general term = Cr *x^r *a^(n-r)
= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)
= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)
= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)
= Cr * 4(2r-n) *x(4r-2n)
now for x^2
4r-2n = 2
4r -10=2
4r =12
r = 3
now for coeff
C(5,3) * 4^(2*3-5)
5!/(3!*(5-3)!) * 4
5*4/(2*1)*4

Answer:
3a
Step-by-step explanation:
the common factors are what make up the terms. 12a is divisible by 3a
9a^2 is divisible by 3a
12a/3a = 4
9a^2/3a
(9a × 9a) / 3a = (9a × 3)
