X is 3
y is 2
you have to replace x with a zero and divide 12 by it and then you do the same for y
Answer:
34.00
Step-by-step explanation:
because get the discounted price, subtract the discount from the original price. To illustrate this principle, here is an example: to take 1/3 off $36.00, divide 36 by 3 and multiply by 1. This becomes 36/3 x 1 to equal 12, which represents a discount of $12.00
Answer:
-1
Step-by-step explanation:
took the exam on edge
Answer:
f. none of the above
Step-by-step explanation:
90 + 63 = 153
180 - 153 = 27
∠A = 27°
Answer:

And if we find the individual probability we got:

And replacing we got:

Step-by-step explanation:
Previous concepts
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".
Solution to the problem
Let X the random variable of interest, 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:
And we want to find this probability:

And we can use the complement rule and we got:

And if we find the individual probability we got:

And replacing we got:
