Answer:
if your asking about how much he has left it's 20
Answer:
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle always equal 180. Therefore:
Let's subtract 102 from both sides. This yields:
Now, notice the that both ∠1 and ∠Y have exactly one arc mark.
Arc-marks denote congruence. Therefore, ∠1 and ∠Y are congruent to each other. In other words:
So, we can substitute ∠Y for ∠1 for our equation. This yields:
Combine like terms:
Divide both sides by 2. So, the measure of our angle is:
And we're done!
48 feet per second because
144/3=48
The answer is 56 percent black pens
Answer:
We are given that Commercial aircraft used for flying in instrument conditions are required to have two independent radios instead of one.
The probability of failure of one radio = 0.0026
So, the probability of failure of both radio =
Now we are supposed to find the probability that a particular flight will be safe with at least one working radio
A) the probability that a particular flight will be safe with at least one working radio = 1- 0.00000676=0.99999324
B)The usual rounding rule of three significant digits not work here because usual rounding rule of three significant digits makes it 1 which means that both radios are working properly.
C)Yes,this probability is high enough to ensure flight safety because it is close to 1
