Answer:
see below PLEASE GIVE BRAINLIEST
Step-by-step explanation:
9/20 = .45 = 45%
9/200 = .045 = 4.5%
9/2000 = .0045 = .45%
Answer:
49
Step-by-step explanation:
Given:
Width = 0.4
Let's take the z value of 95% which is = 1.96
Let's assume population proportion p1 and p2 = 0.5
For margin of error E, the relation between the width and margin of error is 2E.
i.e 2E = 0.4
E = 0.2
To find the sample size, n, let's use the formula :
= 48.02
≈ 49
11 girls and 14 boys
___________________________
11 + 14 = 25 (Total students)
14/ 25 = 0.56
p= 0.56 = 56 %

Can you see the updates?
Do you have any questions regarding the solution?
We have: PZ = 1/2 XZ ( Z is the middle point of XZ )
=> 22 = 1/2(5x - 11)
=> 1/2(5x - 11) = 22
=> 5x - 11 = 22 : 1/2
=> 5x - 11 = 44
=> 5x = 44 + 11
=> 5x = 55
=> x = 55/5 = 11
ANSWER: x = 11
Ok done. Thank to me :>
