Which statement best describes the function h(t) = 210 – 15t?
2 answers:
Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
Step-by-step explanation:
Lets define the terms first
An independent variable is a variable whose values are put in the function. It is the input of a function.
While dependent variable's value depends on the independent variable.
Given function is:
By observing the function, we can see that the function is in terms of t which means that t is the input for the function while h is the name of the function. h(t) which be obtained by putting the values of t is the output.
So,
Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.

Answer:
Cannot create sample
Step-by-step explanation:
We are given the following in the question:
4, -2, -6, 19, 6
Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 0.04 + 38.44 + 104.04 + 219.04 + 3.24 = 364.8
If we add an observation equal to the mean of given sample, then the mean and of new sample will not change.
New sample:
4, -2, -6, 19, 6, 4.2
Sum of squares of differences = 0.04 + 38.44 + 104.04 + 219.04 + 3.24 + 0 = 364.8
Thus, the variance of new sample changes.
Thus, it is not possible to create a sample.
