A number,M, is rounded to 1 decimal place. the result is 9.4 complete the error interval for M​
ivann1987 [24]

Answer:

9.35 \le M \le 9.45

Step-by-step explanation:

Given

M = 9.4 to 1 d p

Required

The error interval

The error interval is represented as:

Lower \le M \le Upper

Where

Lower = M - 0.05

Upper = M + 0.05

So, we have:

Lower = M - 0.05

Lower = 9.4 - 0.05

Lower = 9.35

Upper = M + 0.05

Upper = 9.4 + 0.05

Upper = 9.45

Hence, the error interval: Lower \le M \le Upper is:

9.35 \le M \le 9.45

Step-by-step explanation:

The ratio you are looking for is

freestyle laps : (freestyle + butterfly) laps

so:

8 : (6+8)

Divide by 2 to simplify
