Answer: y = -2/3x + 5
Step-by-step explanation: you find the slope by finding “rise/run”. the rise is -2, and the run is 3, so the slope is -2/3. the y intercept is 5

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Data given
represent the real population proportion for residents born in Colorado
represent the estimated proportion for rsidents born in Colorado
is the sample size selected
Solution to the problem
Let X the random variable of interest (number of residents in the sample), on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
The expected value is given by this formula:

And the standard deviation for the random variable is given by:

The best option is:
B.7.82
Answer:
31 i think
155.3 divided by 5 is equal to 31
Answer:
no solutions exist
Step-by-step explanation:

verify

not true, the equation is impossible
When adding/subtracting fractions you need a common denominator, but you already have one, which is x-3. So in general:
a/c-b/c=(a-b)/c so you just have:
(2x-6)/(x-3) now if you factor 2 from the numerator
2(x-3)/(x-3) the (x-3)s cancel out leaving
2
However! Note that division by zero is undefined, so x cannot equal 3. (because both original fractions had denominators of x-3)
What this all means is that that expression will equal 2 for all real values of x other than 3.
