The altitude to the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 64 and 4. What is the length
Brilliant_brown [7]
Here, Ratio of corresponding length would be equal.
Let, Altitude = x
Then, 64 / x = x / 4
x² = 256
x = √256
x = 16

In short, Your Answer would be 16 units

Hope this helps!

An old house in Pomona, CA is inhabited by a variety of ghosts. Ghost appearances occur in the house according to a Poisson proc
shutvik [7]

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:

P(X\leq x)=1-e^{-xm}

Then, replacing m by 1.4 ghosts per hour we get:

P(X\leq x)=1-e^{-1.4x}

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:

P(x\leq 0.5)=1-e^{-1.4*0.5} =0.503

Answer:

x = 84

y = 96

Step-by-step explanation:

Alternate interior angles are a pair of nonadjacent interior angles that are on opposite sides of the transversal.  Alternate interior angles are equal.

Therefore, x = y - 12

Angles on a straight line add up to 180°

Therefore, x + y = 180

Substituting x = y - 12 into x + y = 180 and solve for y:

⇒ y - 12 + y = 180

⇒ 2y - 12 = 180

⇒ 2y = 192

⇒ y = 96

Substitute found value for y into x = y - 12 and solve for x:

⇒ x = 96 - 12

⇒ x = 84
