Answer:
Let a and b integers and suppose that are even numbers. Then, exist integers k and m such that
and
.
Then,

Since, k and m are integers then n=k+m is an integer. Then, since a + b is of the form 2 by an integer n, then a + b is an even number.
At the start, you have 10 marbles in total and 6 red marbles. The probability of the first event is 6/10.
Since you do not place the marble back in, you now have 9 marbles in total and 3 blue marbles. This probability of the second event is 3/9.
To find the probability of both events occurring, we multiply the two probabilities together. (6•3)/(10•9)=18/90=1/5
Thus, there is a 20% chance of drawing a red marble then a blue marble without placing the red marble back in the bag.

Answer:
G-7×17=119
Step-by-step explanation:
A prime number is a number which has only two factors, 1 and itself.
A composite number on the other hand is any number that has more than two factors.
In the options
In F-5×15=75, 15 can still be decomposed into 5X3
In H-9×19=171, 9 can still be decomposed into 3X3
In J-11×21=231, 21 can still be written as 7X3.
So option G is the only equation which could show Brodricks work.
Answer:
440 hours
Step-by-step explanation:
In this case the aircraft has completed one cycle of service in the first 454 hours of service. Then making the difference between the hours of service and the hours of the first cycle we have:
Hours of the second cycle= Total time in service- time Airworthiness Directive
=468-454=14
Then we have 14 hours of service and need to accumulate the rest to complete 454. It is
454-14=440
Then we need to accumulate 440 hours additional to complete the Airworthiness Directive .
