Domain: 
Range:
Explanation:
The function is 
The domain of a function is the set of all input values for which the function is well defined. Generally, domain consists of all x-values of the function. Hence, the function is defined in the interval .
The range of a function is the set of output values obtained by substituting the value of x in the function. Hence, the function is defined in the interval .
The equations are dependent (they're the same equation).
If you multiply the bottom one by 5, you get the top one.
Answer with explanation:
Given : The computed r -value = 0.45
Sample size : n=18
Degree of freedom : 
Now, the critical value for Pearson correlation coefficient for a two-tailed test at a .05 level of significance will be :
( by critical correlation coefficient table)
Since , 
i.e. 0.45>0.468 , then we say that his Pearson correlation coefficient is not significant for a two-tailed test at a .05 level of significance.
Answer:
$1,823.2
Step-by-step explanation:
Simple interest is calculated using the formula
I = P X R X T
where I is the interest amount
P is the principal amount: 45,580.
R is the interest rate which is 4 %, or 0.04%
T is time, One year.
I = $45,580 x 0.04 x 1
I = $1,823.2 x 1
I = $1,823.2
