Assuming 100 kw bulb
<span>We'll start by figuring out how much energy in
kilowatt-hours the light bulb uses per year. We multiply how much power it uses
in kilowatts, by the number of hours in a year. That gives 0.1 kW x 8,760 hours
or </span>876 kWh x 9 bulbs = 7884 kWh
The electricity produced by 4 tons x 2460
kWh/ton = 9840 kwh
<span>Since the produced electricity is bigger so it
is enough</span>
Answer:
Proportion of buildings in the city that have fire code violations: 10%
Uncertainty 0.3 = 30%
Step-by-step explanation:
This situation complies with a binomial model where p is the probability of finding a building having fire code violations and q=1-p
Since in random sample of 40 buildings chosen for inspection 4 of them are found to have fire code violations, the proportion is 4/40 = 0.1 or 10% and p=0.1 as well.
<em>In a</em> <em>binomial model the standard deviation s is:
</em>
<em>
</em>
<em>where n is the sample size</em>. So
and the uncertainty is the standard error SE
