What is the median for the set of data? Ages Stem Leaves
Temka [501]

Answer:

This is a stem leaf data, in which the stem generally stands for the "tens" place value while the leaf stands for the "ones" place value.

Expand the data, and find the median by finding the middle number:

10, 13, 16, 20, 21, 23, 27, 27, 28, 29, 30, 32, 33, 33, 33, 33, 38, 39, 46, 46, 46, 48

There are 22 numbers in all. To find the Median when there is a even amount of numbers, Find the two middle numbers, and find the mean of the two numbers:

(32 + 30)/2 = (62)/2 = 31

31 is your answer.

Pls help it due ASAP and show workings
Effectus [21]

Answer:

it's 70°

Step-by-step explanation:

well first by vertical angles we know that

\angle BAC = \angle DAE\\\\\angle DAE = 4x+6 ( I don't know how to put the symbol xd)

and given we know that

\angle EAF = \angle EAD = 4x+6

solving for x

we know that

\angle CAD = 180\\\\\angle CAB + \angle ABD = 180\\\\4x+6+6x+14=180\\\\10x+20=180\\\\10x=160\\\\x=16

and now for \angle EAF

\angle EAF = 4x+6\\\\\angle EAF = 4(16)+6\\\\\angle EAF = 64+6\\\\\angle EAF = 70
