Answer: Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.

Step-by-step explanation:

Since we have given that

Number of crashes due to pilot error = 699

Number of crashes due to other human error = 88

Number of crashes due to mechanical problems = 156

Number of crashes due to sabotage = 164

Total number of crashes = 699+88+156+164 = 1167

So, Relative frequency distribution :

Pilot error = \dfrac{699}{1167}\times 100=59.89\%

Human error = \dfrac{88}{1167}\times 100=7.54\%

Mechanical problems = \dfrac{156}{1167}\times 100=13.36\%

Sabtoge = \dfrac{164}{1167}\times 100=14.05\%

Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.

Why is -a² is always negative (a ≠ 0) and why is (-a)² is always positive?
hjlf
-a^2=(-1)\cdot a\cdot a

Regardless of the sign of a, we have a\cdot a=a^2\ge0 (never negative). But multiplying by -1 makes it negative.

On the other hand,

(-a)^2=((-1)\cdot a)^2=(-1)^2\cdot a^2=1\cdot a^2=a^2

which can never be negative for real a.

A cooler contains eleven bottles of sports drink: five lemon-line flavored and six orange flavored. You randomly grab a bottle a
Elenna [48]

Answer:

The probability that you would choose lemon-lime and then orange is 3/11 =.273.  

Step-by-step explanation:

These are 'dependent events', which mean that your the event is affected by previous events.  So, because you have eleven total bottles (five lemon-lime and six orange) and you do not replace the first bottle, that would only leave you with ten bottles remaining.  The probability that you will pick the lemon-lime on the first choice is 5/11 because all of the bottles are there.  However, your second choice will only include ten total bottles since you already took one.  The probability that you would choose orange would be 6/10.  When you multiply these two fractions and reduce to simplest form, you get 3/11.

An umbrella has 12 evenly spaced ribs. If viewed as a flat circle of radius 11 units,
erica [24]

Answer:

Area = 121pi/12

~= 31.66 sq units

Step-by-step explanation:

They are talking about looking at an umbrella like its a circle. The radius is 11 units. That is from the center to the edge.

Consecutive means "in a row" or "next to each other" The 12 "ribs" are the like skeleton structure in the umbrella. But they cut the umbrella into 12 areas. They are asking for the area of one "slice". It is 1/12 of the area of the whole circle.

Area of a circle is

A = pi × r^2

Area of one slice is 1/12 of the whole.

A(1 slice)

= 1/12× pi × r^2

See image.
