Answer:
The probability that all the five flights are delayed is 0.2073.
Step-by-step explanation:
Let <em>X</em> = number of domestic flights delayed at JFK airport.
The probability of a domestic flight being delayed at the JFK airport is, P (X) = <em>p</em> = 0.27.
A random sample of <em>n</em> = 5 flights are selected at JFK airport.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The probability mass function of <em>X</em> is:

Compute the probability that all the five flights are delayed as follows:

Thus, the probability that all the five flights are delayed is 0.2073.

Answer:
1+1 = 2
Step-by-step explanation:
-1 + 3 = 2
Answer:
3/2
Step-by-step explanation:
Let it be
C (5;4) , A (2;1) ; B(7;6)
Suppose that C divide the line AB in ratio m/n from point A (AC is m, CB is n)
Use the formula xc=(m*xb+n*xa)/ (m+n)
5=(m*7+2n)/(m+n)
5m+5n= 7m+2n
2m=3n
m/n=3/2
Answer:
y=-1/4x-6
Step-by-step explanation:
The equation of a line is:
y=mx+b (slope-intercept form) where m is the slope and b is the y-intercept. x and y are the x and y coordinates for a point on the line.
Now that we know the equation, we plug in the given numbers into the equation:
y=mx+b
-8=-1/4(8)+b
-8=-2+b
b=-6
Now we know the y-intercept so the equation is:
y=-1/4x-6
