Answer:
0.335
Step-by-step explanation:
1. There is a 30 percent chance of a flight being delayed because of icy weather ,then the probability of being delayed is 0.3 and of being not delayed is 0.7.
2. If a flight is delayed because of icy weather, there is a 10 percent chance the flight will also be delayed because of a mechanical problem, then the probability of being delayed is 0.1 and the probabilty of not being delayed is 0.9.
3. If a flight is not delayed because of icy weather, there is a 5 percent chance that it will be delayed because of a mechanical problem (MP), then the probability of being delayed is 0.05 and the probabilty of not being delayed is 0.95. (See attached probability tree)
Delayed of icy weather - 0.3
Delayed of MP when weather is not icy - 0.7·0.05=0.035
Now, if one flight is selected at random from the airport in January, the probability that the flight selected will have at least one of the two types of delays is
0.3+0.035=0.335
Answer:
<h2>A 16mm</h2>
Step-by-step explanation:
An equilateral triangle is a triangle that has all of its sides equal.
Perimeter of an equilaterial triangle = 3s where;
s is one side of the triangle.
Given the perimeter of ABC = 96mm
Substituting into the formula above to get s;
96 = 3s
s = 96/3
s = 32mm
Hence the length of one side of the triangle is 32mm
If a perpendicular bisector is drawn from angle A to side Line segment B C at point M, then MC will be half of BC and ΔAMC will be a right angled triangle.
Since all the sides of the triangle are equal, hence BC = 32mm. Since MC is the half of BC, then MC = 1/2 of 32mm
MC = 1/2 * 32mm
MC = 16mm
<em>Hence the length of Line segment MC is 16mm</em>

Answer:
a is any number that is multiples of 3
3, 6, 9, 12, etc...
Step-by-step explanation:
5 1/3 ÷ 4/a
16/3 * a/4
16a/12

since denominator is 3, a can be any whole number that is a multiple of 3



so on and so on....
Answer:
a) 
b) 
Step-by-step explanation:
a) This is an exponential distribution question since it is a poisson type problem
Mean rate is 0.95 per 1000 passengers
Mean rate, 
per passenger
Probability that at least 490 passengers will have their baggage handled properly before the next mishandling occurs
:



b) Probability that the number will be fewer than 200 passengers

The y-intercept of the line is (0, -2), the x-intercept is (8, 0). the slope of the line is in fact 1/4
so your answer is C.
hope this helps, God bless!
