To find the values of a and b, we can use the given information about the function f(x) and its derivatives at x = 0.
First, we know that the value of f(0) is 1, which means that when we plug x = 0 into the function, we get f(0) = 20 + a0 + b*0^2 - 0 + 2 = 1. Solving this equation for b, we get b = -1.
Next, we know that the derivative of the function f(x) at x = 0 is ƒ'(0) = 1. The derivative of a polynomial function is given by ƒ'(x) = 2x + ax + bx^2 - 1. Plugging in x = 0, we get ƒ'(0) = 20 + a0 + (-1)*0^2 - 1 = 1. Solving for a, we get a = 1.
Therefore, the values of a and b are a = 1 and b = -1. The sum of these values is a + b = 1 + (-1) = 0.
First, we need to find the probability, P, that the software is the standard version.
Out of 25,000 units, 5,000 were deluxe. That means the remaining 20,000 were standard. So, 20,000 out of 25,000, or

were standard. That means the probability of selecting a standard one at random is P = 0.8.
Next, we need to find the independent probability that any software box will contain the promotion. We know that 1 in 500 will, or

. That means P = 0.002.
To find the compound probability of these two events, we multiply the probabilities together to get

.
Answer:
each cell normally contains 23 pairs of chromosomes, for a total of 46. ... Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes
