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 .
The distance from the kayak to the mountain to the nearest whole number is 43 meters.
The situation will form a right angle triangle as shown below in the diagram.
<h3>Properties of a right angle triangle:</h3>
- One of its angle is 90 degrees.
- The sides and angle can be found by using trigonometric ratios.
The height(opposite side) of the triangle is the kayak distance from the mountain to the lake below. The distance from the kayak to the mountain is the adjacent side of the triangle.
Therefore, using trigonometric ratios,
tan 35 = opposite / adjacent
tan 35° = 30 / a
a = 30 / tan 35°
a = 30 / 0.70020753821
a = 42.8444402023
a = 42.84 meters
a ≈ 43 meters
