Answer:
To find the mean , median and mode of the students.
Step-by-step explanation:
The students choose from the three definitions of average to find the mean, median or mode of the students’ height in the school.
Students develop a strategy, collect and record data, and analyse data to answer this question.
The key concepts are
Consolidating the terms mean, median and mode.
The students should find the median of the height for the school if they have collected the median result of each grade.
Answer:
1 in. : 100 mi
Step-by-step explanation:
Scale = 1 inch : 10 miles
In the scale, the quantity is Length
The relationship between length and Area is;
Area = Length * Length
So inch becomes inch^2
1 inch * 1 inch = 1 i
10 miles * 10 miles = 100
The correct option is;
1 in. : 100 mi
Answer:
<em>Corey stepped back 59.71 feet</em>
Step-by-step explanation:
<u>Right Triangles
</u>
They are a special type of triangle where one of its internal angles is 90°. The basic trigonometric equations stand in this type of triangles. If x is the adjacent leg of a given angle 
, and y is the opposite leg to the same angle, then
:
We can solve for x to get
Corey estimates the height of the tree to be 80 feet. This means we know y=80 and 
. Let's find the horizontal distance at which Corey is looking at the bald eagle:
Now Corey moves back to watch the very same tree at an elevation angle of 41°. The tree has the same height, so
Now we can know the distance Corey walked back by subtracting both distances
