Answer:
0.9355
Step-by-step explanation:
What we will use here is conditional probability formula.
let A be the event that the plane departs on time
and B be the event that it arrives on time
P(A) = 0.87
P(B|A) = 0.93
P(B) = ?
P(A n B) = ?
Mathematically;
P(B|A) = P(B nA)/P(A)
0.93 = 0.87/P(A)
P(A) = 0.87/0.93
P(A) = 0.935483870967742
which is 0.9355 to four decimal places
Answer:
Where is the question. and answer choices
Well think about how many months there’s are!
12 right?
So 12 is the total of months or the denometor
Or bottom number ^^
Now how many months have 31 days?
Figure that out and that your numerator
Answer:No
Step-by-step explanation:49^2=2401. 2401x-16 can’t be factored
Answer:

Step-by-step explanation:
step 1
Find the slope of AB
we know that
The formula to calculate the slope between two points is equal to

we have
A(5,-1), B(9, -9)
substitute the values



step 2
Find the slope of the line that is perpendicular to AB
we know that
If two lines are perpendicular, their their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have

therefore
The slope of the perpendicular line is

step 3
Find the equation of the line in point slope form

we have


substitute

step 4
Convert to slope intercept form
Isolate the variable y
