He is correct.
The further away ( to the left) from 0 a negative number is the smaller it is.
Answer:
The probability is 0.503
Step-by-step explanation:
If the ghost appearances occur in the house according to a Poisson process with mean m, the time between appearances follows a exponential distribution with mean 1/m. so, the probability that the next ghost appearance happens before x hours is equal to:
Then, replacing m by 1.4 ghosts per hour we get:
Additionally, The exponential distribution have a memoryless property, so if it is now 1:00 p.m. and we want the probability that ghost appear before 1:30 p.m., we need to find the difference in hours from 1:00 p.m and 1:30 p.m. no matter that the last ghost appearance was at 12:35 p.m.
Therefore, there are 0.5 hours between 1:00 p.m. and 1:30 p.m, so the probability that the 7th ghost will appear before 1:30 p.m is calculated as:
Answer:
the height is 5x-2
Step-by-step explanation:
factor 25x^2+10x-8=(5x-2)(5x+4)
cancel like terms
height = 5x-2
First off, a triangle's int. angles = 180.
Since it is isosceles, you can make this formula.
180 = 2(4x-11) + 2(6x+1)
Now, you have to solve for x.
180 = 8x - 22 + 12x + 2
180 = 20x - 20
200 = 20x
/20 /20
10 = x
Now substitute
10(6) + 1
60 + 1
61
61 times 2 = 122.
Therefore, angle NLM is 122 degrees.
Proof:
4(10) - 11
40 - 11
29
29 + 29 + 122 = 180
