What are the medians for the height and weight distribution, respectively?
1 answer:
The median for height is: 167
The median for Weight is: 183
<h3>What is the Median of a Data Set?</h3>The middle value or the average of the two middle value of an ordered data set is the median of the data.
Given the following data:
Height: 178, 163, 174, 186, 154, 167, 167, 181, 159, 165, 177, 191, 158
Arranged in an ordered form, we would have:
54, 158, 159, 163, 165, 167, [167,] 174, 177, 178, 181, 186, 191
The middle value is 167. The median for height is: 167.
Weight: 157, 163, 190, 187, 183, 173, 184, 189, 193, 192, 177, 173, 168
Arranged in an ordered form, we would have:
157, 163, 168, 173, 173, 177, [183,] 184, 187, 189, 190, 192, 193
The middle value is 183. The median for weight is: 183.

Answer:
This is trigonomentry
Use SOHCAHTOA
where :
s is sin
c is cos
t is tan
o is opposite (side)
h is hypotenuse (opposite of 90 degree angle)
and a is adjacent (side)
Sin = o/h
cos = a/h
tan = o/a
in this case we are looking for side BC which is the hypotenuse(h)
and we have the side adjacent(a) to angle 71
since we have a and h determine what to use SIN, COS, OR TAN?
we should use Cos
they‘ve given the angle so we should do this...
Cos71 =
Cos71 =
now apply algebra...
6.3/cos71= BC
BC= 19.3507869666
BC = 19.4 (3SF)
