Answer:
(-6, 3)
Step-by-step explanation:
The function f(x) = a |x − h| + k has its vertex at (h, k).
In this case, the vertex is (-6, 3).
Answer:
$23.41
Step-by-step explanation:
Add the cost of each item together.
$9.95 + $13.46 = $23.41
And there may have been sales tax as well but this information was not provided so it is not needed in the answer.

Examples of categorical variables are race, genders, ages, and education levels. While the closing two variables may be considered in a numerical manner by using exact values for age and the high grade completed, it is always informative to put such variables into a relatively small number of groups.
Answer:
a) Sample correlation coefficient, r = 0.7411
bi) test statistic, t = 4.102
bii) P-value = 0.000736
Step-by-step explanation:
a) The formula for the sample correlation coefficient is given by the formula:



r = 0.7511
b)
i) formula for the test statistic is given by the formula:

sample size, n = 4

t = 4.102
ii) Degree of freedom, df = n -2
df = 14 -2
df = 12
The P-value is calculate from the degree of freedom and the test statistic using excel
P-value =(=TDIST(t,df,tail))
P-value = (=TDIST(4.1,12,1)
P-value = 0.000736
