Multiply top and bottom numbers by 10 then divide :)
Answer:
-14
Step-by-step explanation:
I dont really know, it was just a wild guess.
Answer:
Nominal variables.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are;
1. Discrete variable: a discrete variable is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
2. Continuous variable: a continuous variable is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous random variable.
Hence, the other name for continuous variables is nominal variables because they are numerical in nature.
a. Factorize the denominator:
Then we're looking for such that
If , then ; if , then . So we have
as required.
b. Same setup as in (a):
We want to find such that
Quick aside: for the second term, since the denominator has degree 2, we should be looking for another constant such that the numerator of the second term is . We always want the polynomial in the numerator to have degree 1 less than the degree of the denominator. But we would end up determining anyway.
If , then ; if , then . Expanding everything on the right then gives
which tells us and ; in both cases, we get . Then
as required.
