8 0

Step-by-step explanation:

n = 61,647, p = 0.26, q = 0.74

μ = p = 0.26

σ = √(pq/n) = 0.00177

At 0.05 significance, z = 1.96.

0.26 ± 1.96 × 0.00177

(0.257, 0.263)

0.25 is outside of the confidence interval, so we can conclude with 95% confidence that the proportion is greater than 0.25.

What is 5 to the power of 5 - 9 (200 divided by 4) - (10x90) divided by 5 - (4 to the power of 4) x 5 + 156 - 256
yanalaym [24]

5^5-9(200/4)-(10*90)/5-4^4(5)+156-256

= 3125-9( 200/4)-(10*90)/5-(4^4)(5)+156-256

= 3125-(9)(50)- (10*90)/5-(4^4)(5)+156-256

= 3125-450- (10*90)/5-(4^4)(5)+156-256

= 2675-(10*90)/5-(4^4)(5)+156-256

= 2675 - 900/5 - (4^4)(5)+156-256

= 2675 - 180 - (4^4)(5)+156-256

= 2495 - (4^4)(5)+156-256

= 2495 - 1280 + 156 -256

= 1215 + 156 - 256

= 1371 - 256

= 1115


I hope that's help , please if you have question(s) just let me know !

Yanka [14]

Pattern:

10, 100, 1,000, 10,000, 100,000, 1,000,000, 10,000,000, and so on.

Step-by-step explanation:

First, you must start by using 10 and multiplying it 10 times, 10 x 10 = 100.

Then, with 100 you must multiply it by 10 again, 100 x 10 = 1,000.
