Answer:

The circle has like an equation: (x+3)²+(y-2)²=r²

If x=1 then y=5 ==>(1+3)²+(5-2)²=r²==>4²+3²=r²==>r=5 (the radius)

if x=-7 then (-7+3)²+(y-2)²=25 ==>  (y-2)²=25-16==>y=2+3 or y=2-3

The points (-7,5) and (-7,-1) are on the circle.

Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate. monthly temperature
Svetach [21]

Answer:

Interval level of measurement

Step-by-step explanation:

There are four level of measurements; nominal, ordinal, interval and ratio.

Nominal level of measurements separates data into exclusive categories. There is no ranking or order required in the data. Temperature is not divided into categories.

Ordinal level of measurements separates data into exclusive categories like nominal but there is ranking and order required for the data. Temperature doe not require categories or ranking.

Interval level of measurement ranks data where there are differences between units of measure but there is no meaningful zero. For temperature, a zero is not required and the interval between values is interpret-able. For example, the distance between 67 to 67 is the same as distance between 67 to 71, 71 to 75 and 75 to 79 degree f.
