Answer: 1.18
Step-by-step explanation:
Z = (x - mean) / standard deviation
Z = (85 - 71.4) / 11.5
Z = 13.6 / 11.5 = 1.18
Answer:
45.89
This is what is the answer
t = 2.7
1. Use formula provided
2. A = 3500 B = 2000 r = 4.75 n = 12months/4 = 3 months t = ?
3. Solve
3500=2000(1+4.75/3)^3t
3t=logbase(31/12)*1500
t=logbase(31/12)*1500 / 3
t ≅2.568
