Answer:
1 hour
8 min
49 sec
Step-by-step explanation:
we know that
1 m=3.281 ft
1 mi=5,280 ft
<em>Convert 26 mi to ft</em>
26 mi=26*5,280=137,280 ft
<em>Convert 137,280 ft to m</em>
137,280 ft=137,280/3.281=41,840.90 m
using proportion
9.87/100=x/41,840.90
x=41,840.90*(9.87)/100
x=4,129.70 sec
Remember that
1 hour=3,600 sec
1 hour=60 min
1 min=60 sec
4,129.70 sec=4,129.70/3,600= 1.147 h
0.147*60=8.82 min
0.82*60=49 sec
therefore
1 hour
8 min
49 sec

Answer:
34% of lightbulb replacement requests numbering between 47 and 52
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 52
Standard deviation = 5
Between 47 and 52:
52 is the mean and 47 is one standard deviation below the mean.
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean.
Since the normal distribution is symmetric, of those, 34% are within 1 standard deviation below the mean and the mean(47 and 52) and 34% are within the mean and one standard deviation above the mean(52 and 57).
So
34% of lightbulb replacement requests numbering between 47 and 52
