Answer:
−3x^2-12x+63
Step-by-step explanation:
simplify-3(x-3) you should get -3x+9.
then use foil to get (-3x+9)(x+7)
you multiply -3x with (x+7) and tou should get (-3x^2-21x)
then multiply 9 with (x+7) and you should get (9x+63)
now you should have the numbers: -3x^2, -21x, 9x, and 63.
combine like terms: add 9x to -21x and tou will get -12x.
Now place the numbers in the correct order: variables with exponents, then nirmal variables, then non variables
The answer to the question is x=4+2.5y
Add all of them together and then divide by the number digits. So it would be 6/4= 3/2
The probability that a U.S. household selected at random has a computer and has Internet access will be 0.72. The C and I are independent events. Then the correct option is B.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Approximately 80% of households in the United States have computers. Of those 80%, 90% have Internet access.
Then the probability that a U.S. household selected at random has a computer and has Internet access will be
P(C and I) = 0.80 × 0.90
P(C and I) = 0.72
Then the C and I are independent events.
Then the correct option is B.

Answer:
The answer is 0.992
Step-by-step explanation:
To calculate of the probability of the event that at least two of the women are standing next to each other. We can simple subtract the probability of every women standing with a man from 1. So probability of every women standing with a man is 5!*4!/9!. Because they can only stand in order of WmWmWmWmW. So the answer is:
