Answer:
(3√26, 0)
Step-by-step explanation:
Finish your work by evaluating the sine and cosine. The imaginary part corresponds to the y-coordinate in (x, y) form.
3√26(cos(360°) +i·sin(360°)) = 3√26(1 +0i)
In rectangular form, that is ...
(3√26, 0)
So the greatest common factor 48 and 120 is 24.
It would be 15 feet per minute if that is what you wanted
Answer:
(3+p)
Step-by-step explanation:
solution
first expression=9-P^2
=3^2 - P^2
=(3+P) (3-p)
second expression=p^2 + 3p
= p(3+p)
Therefore lCM= (3+p)
<h3>Answer: 0.4545</h3>
============================================
Work Shown:
Define the following events
- B = the man takes the bus
- S = the man takes the subway
- L = the man is late
- L' = the man is not late (ie the man is on time)
Draw out a probability tree. See diagram below.
From the tree diagram, we can figure out that P(L) = 0.44 which is the probability of being late. Note how I considered the two probabilities P(B & L) and P(S & L)
- P(B & L) = probability of taking the bus and being late
- P(S & L) = probability of taking the subway and being late
The events (B & L) and (S & L) are mutually exclusive, so we can add them up. Combining them will have us find the overall probability of being late. For more information, check out the law of total probability.
--------------------
Now use a conditional probability formula to find...
P(B|L) = probability the man takes bus given he is late
P(B|L) = P(B & L)/P(L)
P(B|L) = 0.2/0.44
P(B|L) = 0.45454545454546 approximately
P(B|L) = 0.4545 rounding to four decimal places
note: when I write "P(B|L)", I am using a vertical bar. I'm not using an uppercase letter 'i' or a lowercase letter L.
