X, y - the lengths of the sides of the pathway
The area of a rectangle is the product of the lengths of its sides. The area is 350 m².
The perimeter of a rectangle is two times the sum of the lengths of its sides. The perimeter is 90 m.
Substitute 45-x for y in the first equation:
The dimensions of the pathway are 10 m by 35 m.
The length of the pathway is 35 m.
7x + 6y = 21 ⇒ 7x + 6y = 21
1x + 3y = -12 ⇒ 2x + 6y = -24
5x = 45
5 5
x = 9
x + 3y = -12
9 + 3y = -12
- 9 - 9
3y = -21
3 3
y = -7
(x, y) = (9, -7)
Answer:
Nominal
Step-by-step explanation:
There are four levels of measurement of data listed below in increasing order:
Nominal
Ordinal
Interval
Ratio
The nominal level of measurement is the lowest level that deals with names, categories and labels. It is a qualitative expression of data e.g Colors of eyes, yes or no responses to a survey, and favorite breakfast cereal all deal with the nominal level of measurement.
Data at this level can't be ordered in a meaningful way, and it makes no sense to calculate things such as means and standard deviations.
