Answer:
5 feet 9 in.
Step-by-step explanation:
15 feet = 180 in.
9 feet = 108 in.
108 in. + 3 in. = 111
180 in. - 111 in. = 69 in.
69 in. = 5 feet 9 in.
as you can see above... notice the middle term, in a perfect square trinomial, the middle term is, 2 times the guy on the left, without the exponent, and times the guy on the right
so.. .what we have here ... let's see yours is
so.. we have a missing guy there, the guy on the right hmm what the dickens would that be anyway?
well... let us use the middle guy
aha ... there's our guy on the right.... so now we know is 1/5
now... let us call or very good friend Mr Zero, 0
if we "add" whatever, we also have to "subtract" whatever, since all we're really doing is, borrowing from 0
thus
![\bf x^2-\cfrac{2}{5}x\implies x^2-\cfrac{2}{5}x\quad +\left( \cfrac{1}{5} \right)^2\quad -\left( \cfrac{1}{5} \right)^2 \\\\\\ \left[ x^2-\cfrac{2}{5}x +\left( \cfrac{1}{5} \right)^2 \right]-\left( \cfrac{1}{5} \right)^2\implies \left( x-\cfrac{1}{5} \right)^2 - \cfrac{1^2}{5^2} \\\\\\ \left( x-\cfrac{1}{5} \right)^2 -\cfrac{1}{25}](https://tex.z-dn.net/?f=%5Cbf%20x%5E2-%5Ccfrac%7B2%7D%7B5%7Dx%5Cimplies%20x%5E2-%5Ccfrac%7B2%7D%7B5%7Dx%5Cquad%20%2B%5Cleft%28%20%5Ccfrac%7B1%7D%7B5%7D%20%5Cright%29%5E2%5Cquad%20-%5Cleft%28%20%5Ccfrac%7B1%7D%7B5%7D%20%5Cright%29%5E2%0A%5C%5C%5C%5C%5C%5C%0A%5Cleft%5B%20x%5E2-%5Ccfrac%7B2%7D%7B5%7Dx%20%2B%5Cleft%28%20%5Ccfrac%7B1%7D%7B5%7D%20%5Cright%29%5E2%20%5Cright%5D-%5Cleft%28%20%5Ccfrac%7B1%7D%7B5%7D%20%5Cright%29%5E2%5Cimplies%20%5Cleft%28%20x-%5Ccfrac%7B1%7D%7B5%7D%20%5Cright%29%5E2%20-%20%5Ccfrac%7B1%5E2%7D%7B5%5E2%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Cleft%28%20x-%5Ccfrac%7B1%7D%7B5%7D%20%5Cright%29%5E2%20-%5Ccfrac%7B1%7D%7B25%7D)
Answer:
(in tabular format)
<em />
<em>x 1 5 10</em>
<em>p(x) 0.4 0.3 0.3</em>
<em />
Step-by-step explanation:
probability mass function (PMF) gives us probabilities of possibilities of a random variable. It is usually shown in a tabular format with Random Variable (x) in one column and each associated probability [P(x)] in its respective column.
Here, our random variable is the yearly revenues of being "very successful", "moderately successful", and "unsuccessful".
So we can write [in probability notation]:
P(x=10) = 0.3
P(x=5) = 0.3
P(x=1) = 0.4
This, in tabular format would be the probability mass function (PMF).
<em>x 1 5 10</em>
<em>p(x) 0.4 0.3 0.3</em>
