Answer:
55 miles
Step-by-step explanation:
11 miles = 45 min
speed = distance/time
speed = 11/45
speed = 0.2444 miles/min
for 225 min, speed is same
distance = speed * time
= 11/45 * 225
=55 miles
14.99n + 4.99
If we ordered 3 CDS, we need to replace 3 for n.
14.99(3) + 4.99
44.97 + 4.99
49.96
Answer: $49.96

Answer:
97
Step-by-step explanation:
Given that:
Low = 43bpm
High = 115 bpm
Error = 3
α = 90%
To find the range estimate :
Standard destviation = (high - low) / 4
Standard deviation = (115 - 43) / 4
Standard deviation = 72/4 = 18
The sample size,(n) :
n = [(Zα/2 * sd)/E] ²
2 - tail = (Zα/2) = 1.645
[(Zα/2 * sd)/E] ² = [(1.645 * 18) / 3]² = (29.61/3)²
= 97.41
Sample size = 97
