Answer: p X 0.7
Step-by-step explanation: i think this is the correct answer because when you buy something with a discount you are paying that much less from the initial value (1.0). So your answer would be price X (1.0-discount in decimal form). im really sorry if that was wrong or confusing
Answer:
-1/2
Step-by-step explanation:
the slope is difference in y over difference in x, so (-3-(-1))/(2-(-2)): aka -2/4 aka -0.5 or -1/2
plug in the points to find the y intercept,
the equation of the line is y = -0.5x -2 incase you need it.
That depends. If you have a finite data set, you would add up all the points you have and divide by the total count.
Or, if you are working with pure distributions, the mean is the same as the expected value of the corresponding random variable.
Suppose you have a discrete random variable

with a given probability mass function

, then the mean is given by

which would mean you take all the possible probability for the event that

, multiply each by that

, and add them together.
If the distribution is continuous, say a random variable

that has probability distribution function

over some support

, then the mean is

Answer:
2/3
Step-by-step explanation:
4 goes into 8 twice and 4 goes into 12 three times therefore it would be 2/3
