Answer:
Step-by-step explanation:
The graph crosses the y-axis at (0,-2).
The slope of the graph is 3.
y = 3x - 2
Answer:
Step-by-step explanation:
The altitude falls in the middle of the line.
So, the point at which it falls in the bottom line is the midpoint, so the length of the blue triangle would be 6/2 = 3
So, the blue triangle has length of 3 and height of H and hypotenuse of 10.
Now, we will use Pythagorean Theorem to solve for H. The theorem is:
Leg^2 + Another Leg^2 = Hypotenuse^2
We know one leg of the triangle is 3 and another leg is H and hypotenuse is 10, so we substitute and solve:
This is the exact answer for H
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
