Answer:
44.65 inches
Step-by-step explanation:
Height of ramp = 16 inches
Length of ramp, l
Angle formed by ramp and ground = 21°
Using Pythagoras :
Sinθ = opposite / hypotenus
Sin21° = 16 / l
0.3583679 = 16 / l
0.3583679 * l = 16
l = 16 / 0.3583679
l = 44.646855 inches
Hence, length of ramp is 44.65 inches
Answer: b) statistic
Step-by-step explanation:
- Population = A large groups of individuals sharing the same or similar characteristic by the point og study.
- Sample = It is a subset of population .
- Parameter = It is measure of characteristic in population.
- Statistic = It is measure of characteristic in sample.
Since the average score was taken by the group of 20 which is nothing but the sample.
That means, the average score is an example of<u> statistic</u>.
Hence, the correct option is b) statistic .
