Answer:
y = -(x+4)² +7
Step-by-step explanation:
I find it convenient to factor the leading minus sign from the first two terms, then work with what's left.
... y = -(x² +8x) -9
Now, add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
... y = -(x² +8x +4²) -9 +4²
... y = -(x +4)² +7 . . . . . . . . . rewrite parentheses as a square; collect terms
The answer to the question is 21.333 yards
Temperature data consists of the characteristics of the four levels of
measurement.
<h3>Response:</h3>
- The temperature of 26 refrigerators would be considered as <u>ratio data</u>.
<h3>Reasons that make the refrigerator temperature, ratio variables;</h3>
The question possibly relates to the levels of measurement.
Levels of measurement defines how the statistical data within variables are interrelated.
The four levels of measurement are;
- Nominal data; Variables that consists of categories and levels.
- Ordinal data; Variables that have categories that can be ranked.
- Interval data; Categorical variables that can be ranked and have equal intervals that are known.
- Ratio data; Data that have the above properties and also has a defined true zero value.
Therefore, given that the temperatures of the refrigerators can be
categorized, ranked, have intervals that are defined, and has a true
meaning of zero, the absolute zero temperature, the data would be
considered as a <u>ratio data</u>.
