What is the means-to-MAD ratio of the two data sets, expressed as a decimal?
vlada-n [284]
Data set 1: 14,15,17,18,21 
mean: (14+15+17+18+21)/5 = 85/5 = 17
mad
17-14 = 3
17-15 = 2
17-17 = 0
17-18 = 1
17-21 = 4 

(3+2+0+1+4)/5 = 10/5 = 2

17/2 = 8.5 is the means-to-mad ratio

Data set2: 15,16,17,20,22
mean = (15+16+17+20+22)/5 = 90/5 = 18
mad
18 - 15 = 3
18 - 16 = 2
18 - 17 = 1
18 - 20 = 2
18 - 22 = 4

(3+2+1+2+4)/5 = 12/5 = 2.4

18/2.4 = 7.5 means to mad ratio

ative section 3. a) The angle of elevation of the top of a tree observed from a point 60 m away from its foot is 45. Find the he
Zigmanuir [339]

Answer:

The height of the tree is is 60m

Step-by-step explanation:

Let's answer a, as it is the only complete question.

We know that the angle of elevation of the top of a tree observed from a point 60m away, is 45°.

We can model this with a triangle rectangle, a sketch of it can be seen below (assuming that you are looking it from the ground).

You can see that the adjacent cathetus to the 45° angle is equal to 60m

And the opposite cathetus is the measure we want to find.

Now you can remember the trigonometric relation:

tan(a) = (opposite cathetus)/(adjacent cathetus).

So to find the height of the tree we need to solve:

tan(45°) = H/60m

This is just:

tan(45°)*60m = H  =60m

The height of the tree is is 60m
