The ____________ of probability tells that to determine the chances of independent events, such as the likelihood of inheriting
____ [38]

Answer:

The product rule of probability tells that to determine the chances of independent events, such as the likelihood of inheriting a certain allele, probabilities are multiplied

Step-by-step explanation:

The product rule of probability states that the probability of independent events occurring together can be gotten by multiplying the probability of each event occurring alone.

The product rule is given as P(A*B) = P(A) *P(B).   Where A and B are two independent events. For example when picking cards from a deck of 52 cards, the probability of getting an ace is 4/52 = 1/13 (because there are 4 aces in a deck of 52 cards) . The probability of picking a heart is 13/52 = 1/4. Therefore the probability of picking the ace of hearts is 1/4*1/13 =1/52.

Which description compares the vertical asymptote(s) of Function A and Function B correctly?
r-ruslan [8.4K]
Function A:  f(x)=\frac{1}{x}+4.  Vertical asymptotes are in the form x=, and they are a vertical line that the function approaches but never hits.  They can be easily found by looking for values of <em>x</em> that can not be graphed.  In this case, <em>x</em> cannot equal 0, as we cannot divide by 0.  Therefore <em>x</em>=0 is a vertical asymptote for this function.  The horizontal asymptote is in the form <em>y</em>=, and is a horizontal line that the function approaches but never hits.  It can be found by finding the limit of the function.  In this case, as <em>x</em> increases, 1/<em>x</em> gets closer and closer to 0.  As that part of the function gets closer to 0, the overall function gets closer to 0+4 or 4.  Thus y=4 would be the horizontal asymptote for function A.
Function B:  From the graph we can see that the function approaches the line x=2 but never hits.  This is the vertical asymptote.  We can also see from the graph that the function approaches the line x=1 but never hits.  This is the horizontal asymptote.

A piece of rectangular sheet metal is 20 inches wide. Its is to be made into a rain gutter by turning up the edges to form paral
vivado [14]
Turning up the edges of the sheet metal will result in the 20 inches of metal being divided into x inches of the first side, then the unknown width of the gutter (let's call it "y") and then again x inches for the second side.

 As a picture: x|______|x/y

 As a formula: 20 = x + y + x = 2x + y

Resolving this to y we get: 20 - 2x = y

and switching it around: y = 20 - 2x,

Now for part b) of your question:
The area of the gutter's cross-section is its width (y) multiplied with its height (x).

A(x,y) = x * y
If we use our result from a) to eliminate y then we can see that
A(x) = x * y = x * (20-2x) = 20x-2x^2
So I'd say that the answer to part b) should be: A(x) = 20x - 2x^2
