Answer:
probability that the child DOES NOT play the piano

Step-by-step explanation:
A students' choir contains 25 children
n(S) =25
The number of students play the piano =5
Let 'E' be the event of the child play the piano so n(E) =5
The probability of that the child play the piano


Let 'E⁻ be the event of the child play does not play the piano


<u>Conclusion</u>:-
probability that the child DOES NOT play the piano

Check the picture below.
let's recall that a square has all equal sides, so the perimeter of the square is about 31, and Alicia has 32 inches of trim, so she's golden.
Y+1=[m(the slope)](x+2), y=mx+2m-1, it is impossible to get the answer without the graph.
Answer:
0.68
Step-by-step explanation:
The formula for z test is given above as:
z = p' - p/√(pq/n)
p' = sample proportion
= Number of infested samples(trees)/ Number of samples
p' = 127/1000 = 0.127
p = 12% = 0.12
q= 1 - 0.12 = 0.88
n = number of samples = 1000
z = 0.127 - 0.12/√(0.88 × 0.12/1000)
z = 0.007/√0.0001056
z = 0.007 /0.0102761861
z = 0.6811865737
Therefore, the z test statistic is approximately ≈ 0.68
