Answer:
d.
Step-by-step explanation:
Inferential Statistics is one of two statistical methods that is used to analyze data by drawing conclusion about a bigger population from a sample. In other words, inferential statistics allows a researcher to make assumptions and arrive at conclusions about a larger group known as the population, by using just a small portion known as the sample of the population as a study. The study of this small portion is then used to explain the behaviour of the entire population. Random sampling is carried out to ensure that the sample is a true representation of the population
It involves:
- A definition of the population to be studied.
- Drawing a sample out of this population.
- Analysis of data.
Answer:
y=6x+3
Step-by-step explanation:
A line that is parallel to another line, has the opposite slope of the first line.
Answer:
Step-by-step explanation:
Given: f(x)=5x^3-51x^2+77x+100/x^2-11x+24
Please use parentheses to eliminate any ambiguity:
f(x) = (5x^3-51x^2+77x+100) / (x^2 - 11x + 24)
or (better yet):
5x^3-51x^2+77x+100
f(x) = ---------------------------------
x^2 - 11x + 24
The vertical asymptotes here are at the zeros of the denominator:
x^2 - 11x + 24 = 0, This quadratic equation has coefficients a = 1, b = -11 and c = 24. Thus, its roots (zeros) are:
-(-11) ± √( 121 - 4(1)(24) )
x = -------------------------------------
2(1)
or:
11 ± √( 25 )
x = --------------------
2
or: x = 8 and x = 3
The vertical asymptotes are x = 8 and x = 3.
If we attempt to divide x^2 - 11x + 24 into 5x^3 - 51x^2 + 77x + 100, we see that the first term of the quotient is 5x. As x increases or decreases without bound, 5x goes to either ∞ or -∞, so we conclude that there is no horiz. asymptote. Continuing this division results in:
5x + 4 + a fraction
This represents the slant asymptote, y = 5x + 4
first plot (0,2) then (-1,5)
Answer:
A
Step-by-step explanation:
The square root of 5 is irrational because it cannot be expressed as a fraction.
Meanwhile, all 3 other answer choices are not irrational because they can be put into fraction form.
