Answer:

The graph is symmetric. The mean and median are about equal in a symmetric graph. The median is shown as 109, so the mean is approximately 109.

Step-by-step explanation:

The graph is symmetric.

Because the graph is symmetric, the mean and median should be approximately equal.

According to the graph, the median is 109. Therefore, the mean is approximately 109.

Airlines monitor the causes of flights arriving late. A total of 75% of flights are late because of weather, while 35% of flight
LekaFEV [45]

Answer:

36% is the  joint probability that a flight arrives late because of weather and ground operations

Step-by-step explanation:

Given

% of flight late because of weather = 0.75

% of flight late because of ground operation = 0.35

% of flight late because of both weather and ground operation = 0.10

The probability of joint probability that a flight arrives late because of weather and ground operations is equal to

p (A and B) + {P(A) * P(B)}

0.10 + (0.75 * 0.35)

0.36

or 36%

How do you divide factorials by lesser factorials again?
meriva

Answer:

(answer in explanation)

Step-by-step explanation:

so, whenever you divide factorials, as soon as you get it to be the same ! on the top and bottom of the fraction, they cancel out like any other fraction would.

So, lets say you're dividing 55! / 50!

55! can also be thought of as 55 x 54 x 53 x 52 x 51 x 50!

\frac{55*54*53*52*51*50!}{50!} = 55 * 54 * 53 * 52 * 51

Then you can simply solve the remaining equation

( 55 * 54 * 53 * 52 * 51 = 417,451,320)

hope this helps!!

How many solutions does the system of equations shown below have?
rjkz [21]

Answer:

one solution with a y value of 5

Step-by-step explanation:

/| x+y-4 = 0| x-y-6 = 0

We try to solve the equation: x+y-4 = 0

x+y-4 = 0 // - x-4

y = -(x-4)

y = 4-x

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| x+x-6-4 = 0| y = 4-x

2*x-10 = 0 // + 10

2*x = 10 // : 2

x = 10/2

x = 5

We insert the solution into one of the initial equations of our system of equations

For y = 4-x:  

y = 4-5

y = -1

We get a system of equations:

/| y = -1| x = 5
