The answer is b.
when x decreases, f(x) decreases.
when x increases, f(x) increases.
To solve the inequality, you isolate the variable on one side using transformations that produce equivalent inequalities, which have the same solution(s). Solve x+5≥3. Graph the solution. The solution is all real numbers greater than or equal to -2.
Using the t-distribution, it is found that the 95% confidence interval for the population mean rating for Miami is (5.73, 6.95).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a <u>two-tailed 95% confidence interval</u>, with 50 - 1 = <u>49 df</u>, is t = 2.0096.
Considering the given sample, the other parameters are given as follows:
Hence, the bounds of the interval are:

Answer:
Y = -1
Step-by-step explanation:
y has multiple meaning
In graphs, y is the coordinate point we need to plot after assuming a promising value of other coordiante like x
see image below for example
Similarly, it can be said that y is a function of variable x , that is the value of y varies with variable x
