Answer:
(Incomplete question); usually the sum of the probabilities for all values of a random variable is 1.
Step-by-step explanation:
A random variable is a numerical valued variable on a defined sample space of an experiment with expressions such as X or Y.
A good example is a company that wants to analyse the number of calls received at its Help Desk from 8 am to 12 pm in a month. The number of calls from customers at the Help Desk during the defined time period (8 am - 12 pm) is the random variable.
Another example is when a coin is tossed twice; the sample space is either {HH, HT, TH, TT} by assigning numerical values to the random variable we may define the random variable X as the total number of tails (T), meaning X values becomes 0,1 and 2 .
Well If you tell me what you're solving for I can probably help
Answer:
16 ounces
Step-by-step explanation:
Yes for the first one, yes for the second one, and yes for the third one although your subtraction equation had the wrong year (its not 1847 its 1846) but the answer was right, 65.
Standard form is just the polynomial in decreasing number of degree. So you have to rearrange it as : x^2 - 8x + 1. This is a second degree trinomial, as it has three terms and the highest number of degree being 2.
