Convert 820,000 Btu/hr to kW. Report your answer in scientific notation with the appropriate number of significant figures. Hint

kupik [55]

Answer:

2.40 × 10²

Step-by-step explanation:

Data provided in the question:

we have to convert 820,000 Btu/h to kW

Now,

1 kW = 3412.142 Btu/h

or we can say

1 Btu/h = 0.00029307107 kW

Therefore,

820,000 Btu/hr in kW will be

= 820,000 × 0.00029307107 =

= 240.3182774

= 2.40 × 10²

Hence,

according to the question, X will be 2.4 and the term in the power of 10 is 2

Among fatal plane crashes that occurred during the past 55 years, 415 were due to pilot error, 96 were due to other human err

azamat

Answer:

Relative frequency:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

The most serious threat to aviation safety is, according to this data, "mechanical failures". It can be improved by more rigorous inspection and better maintenance policies and execution.

Step-by-step explanation:

We have the data for fatal plane crashes. The sum of plane crashes is

We can calculate the relative frequency as:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

We can see that the most frequent cause is "mechanical problems", with a relative frequency of 0.45.
