3y - 2x + z - 2x + 3(x + y)
3y - 2x + z - 2x + 3*x + 3*y
3y - 2x + z - 2x + 3x + 3y
3x - 2x - 2x + 3y + 3y + z
-x + 6y + z
Answer:
a. variable
Step-by-step explanation:
X = number of days a Lake Tahoe Community College math student is absent
X is a random variable.
A random variable is a variable whose value is a numerical outcome of a random phenomenon.
A random variable's possible values might represent the possible outcomes of a yet-to-be-performed experiment.
Random variables are often denoted with capital letter
s and they can be discrete or continuous.
No 1 1/4 is greater than 3/4
Percent of error is the same as percent of change so
115 -82.5=33
so you have to take the original number and divid it by 33 so
33/115 which is .2869565217 i think you have to round it so it is .29 then you have to turn it into a percent which you move the decimal twice to the right to get 29%
Answer:
First, find the change in the y-values by subtracting from one row to the next, then find the change in the x-values by subtracting from one row to the next, then finally, just divide the difference in the y-values by the difference in the x-values.
