Answer:
125%
Step-by-step explanation:
so you are increasing by $10, and $10 is 25% of $40, so the percent change is 125%
About $0.75 per person.
First, let’s find the cost for each portion of hamburger meat and the cost for each bun.
We can do this for the meat by doing 1.49/4 to get 0.3725.
Now we can do the same with the buns by doing 2.99/8 to get 0.37375.
Now just add these together. 0.3725+0.37375 is 0.74625, which can be rounded to $0.75.
The cost per person is approximately $0.75.

Answer:
Determine the conditional probability distribution of X given that Y = 1 and Z = 2. Round your answers to two decimal places (e.g. 98.76).
answer:
Given that Y = 1 : 2/5
Given that Z = 2 : 3/5
Step-by-step explanation:
The conditional probability distribution of X F x | yz^( x )
Given that Y = 1
F x | yz . ( x | yz ) = 2/5
Given that z = 2
= 3/5
attached below is the detailed solution
Answer:
Step-by-step explanation:
So in this example we'll be using the difference of squares which essentially states that:
or another way to think of it would be:
. So in this example you'll notice both terms are perfect squares. in fact x^n is a perfect square as long as n is even. This is because if it's even it can be split into two groups evenly for example, in this case we have x^8. so the square root is x^4 because you can split this up into (x * x * x * x) * (x * x * x * x) = x^8. Two groups with equal value multiplying to get x^8, that's what the square root is. So using these we can rewrite the equation as:

Now in this case you'll notice the degree is still even (it's 4) and the 4 is also a perfect square, and it's a difference of squares in one of the factors, so it can further be rewritten:

So completely factored form is: 
I'm assuming that's considered completely factored but you can technically factor it further. While the identity difference of squares technically only applies to difference of squares, it can also be used on the sum of squares, but you need to use imaginary numbers. Because
. and in this case a=x^2 and b=-4. So rewriting it as the difference of squares becomes:
just something that might be useful in some cases.
A1 = 0.91
a6 = -0.14
sum = (0.91+-0.14) /2
sum = 2.31
