Let the event 'arrive on time' be AO.
Let the event 'leave on time' be LO.
P(AO\cap LO)=0.8
P(AO) = 0.84
P(LO) = 0.86
P(LO|AO)=\frac{P(AO\cap LO)}{P(AO)}=\frac{0.8}{0.84}=0.95

Answer: Our required probability is 0.952.

Step-by-step explanation:

Since we have given that

Probability that train arrive on time and leaving on time = 0.8

Probability that train arrive on time = 0.84

Probability that train leave on time = 0.86

We need to find that probability that it will on time given that train arrived on time.

We will use "Conditional probability":

P(\text{Leave on time}|\text{arrive on time})=\dfrac{P(\text{Arrive}\cap \text{Leave})}{P(Arrive)}=\dfrac{0.8}{0.84}=0.952

Hence, our required probability is 0.952.

GREYUIT [131]
The answer is D. First, it is the segment addition postulate because the two segments make up the whole. Second, it's substitution because you are substituting EF + FG for FH.

Hope this helps!

Which line has the same slope as the line passing through (- 4, -1) and (-1, 8)
Troyanec [42]

The slope is [ 8 - (-1) ] / [ -1 - (-4) ] = 9 / 3 = 3;

The line has the equation: y - 8 = 3( x + 1);

y - 8 = 3x + 3;

y = 3x + 11.

15. The dollar amount y that remains to be repaid on a loan x months after the loan is issued is represented by y=-1000x + 8000.
irina [24]

Answer:

1) $8000

2) $1000

3) 8 months, since y represents our remaining amount to be paid, we set it equal to 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.

Step-by-step explanation:

We have the equation y = -1000x + 8000 which follows the linear equation:

y = mx + b, where m is our slope and b is our y-intercept

1) The initial balance can be found with our constant "b" which in this case is 8000. You can also plot the function of y and you will find that 8000 is the intercept when x = 0, aka the start

2) We can calculate the rate of change for when the loan is repaid by looking at the slope "m", in this case it is 1000. It subtracts 1000 each month, meaning $1000 is being payed and taken out of the bank account

3) To find how many months it will take for the loan to be repaid, let's solve for x when y = 0.

0  = -1000x + 8000

-8000 = -1000x

8 = x

It will take 8 months. Why? Since y represents our remaining amount to be paid, we set it = 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.
