Answer:

B. 21 and 19/25

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

21.76=21.761

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100

21.761×100100=2176100

Find the Greatest Common Factor (GCF) of 2176 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,

2176÷4100÷4=54425

Simplify the improper fraction,

=211925

In conclusion,

21.76=211925

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.
