A) The exact area is just the difference between the two numbers:
2.69-2.67 = 0.02 units
b) Calculate the area of the circle with the two values for the radius:
A = <span>πr^2 = </span><span>π * 2.69^2 = </span>22.7328786 units squared
A = πr^2 = <span>π * 2.67^2 = 22.39609987 units squared
</span> Then, find the difference between the two numbers:
22.7328786 - 22.39609987 = 0.336778731 <span>≈ 0.34 units squared (2.s.f.)
c) I'm not sure what the question is asking for (perhaps the rounding expressed </span><span> at the end of b?)
d) The relative error is the absolute (exact) error divided by the actual value for </span><span> the radius:
</span> 0.02/2.67 = 0.007490636704 ≈ 0.0075 (2.s.f.)
The percentage area is the absolute (exact) error divided by the actual value for the area, and then multiplied by 100 to find a percentage:
(0.336778731/22.39609987)*100 = 1.503738298 <span>≈ 1.50% (2.s.f.)</span>
It would be 2. Have a nice day.
Answer:
Likert Scale Question Format
Step-by-step explanation:
A Likert scale is a psychometric scale commonly involved in research that makes use of questionnaires. The Likert scale assumes that the strength of an attitude is linear, assumes that attitudes can be measured.
In addition to measuring statements of agreement, Likert scales can also be used to measure frequency, quality, importance, and likelihood, etc.
The data obtained can be summarize using a median or a mode.
The distribution of observations can also be displayed in a bar chart (it can’t be a histogram, since the data is not continuous.
