I think so, but there may be some exceptions--if any.
Based on the calculation done, there are 15 baskets of peaches.
x + y = 23 ..... i
20x + 18y = 430 ...... ii
From equation i, x = 23 - y ..... iii
Put equation iii into ii
20x + 18y = 430
20(23 - y) + 18y = 430
460 - 20y + 18y = 430
2y = 30
y = 30/2 = 15
x + y = 23.
x + 15 = 23
x = 23 - 15 = 8

Answer:
N = 3,120 (Approx)
Explanation:
Given:
z- score for 99% confidence = 2.58
Proportion (P) = 75% = 75 / 100 = 0.75
E = 2% = 0.02
Q = 1 - P = 1 - 0.75 = 0.25
Computation:





Therefore, N = 3,120 (Approx).
