Converting units from feet to yards is easy. However, it becomes tricky when converting square yard to square feet but it is easy if you get the gist of it. Simply square both sides of the conversion:
Since 3 feet = 1 yard
(3 feet)^2 = (1 yard)^2
9 feet^2 = 1 yard^2
In the same way, if you want to convert from cubic feet to cubic yard, simply cube (raise to the power of 3) both sides. :)
Y^2-9y+81 can not be factored with any rational numbers
Answer:
categorical ordinal
Step-by-step explanation:
The variable is categorical because not important, somewhat important and very important are three different categories and these categories are assigned numerical value 1,2 and 3 still numerical value assigning cannot lead to quantitative variable because 1 still means category not important. The scale of measurement in the variable is ordinal because it has meaningful order from category 1 not important to category 3 very important.
Answer:
probability that their average salary is more than $77,500 is 0.1587
Step-by-step explanation:
standard error
= 10,000/sqrt(16)
=10,000/4
= 2500
(77,500 - 75000)/2500
2,500/2500
= 1
p (z > 1) = .1587
So, the probability that their average salary is more than $77,500 is 0.1587
