Do you know what regifting is? it is loosely defined as "giving someone a gift that was originally given to you without telling the recipient the origin of the gift." now that you know, how often do you engage in regifting? in a survey of 5547 persons, the answers to that question were as follows.
response to the question: how often do you engage in regifting?
very often → 143 votes
every now and then → 811 votes
not very often → 1759 votes
never → 2805 votes
i'm not sure → 29 votes
current number of voters: 5547
if one of the persons is selected at random, what is the empirical probability of the following?
(a) the person very often engages in regifting.

(b) the person never engages in regifting.

(c) if you get a gift and you assume that the results of the survey apply to that gift, what is the probability that you are getting a regift? assume that the people who give regifts are the ones that did not answer "never.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

a sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°c. if the system is at dynamic equilibrium, which of these statements is true?  

its c
