Answer:
mean: 40.25
median: 40
mode: 40
Step-by-step explanation:
No.
If 42 is removed all values will be equal to 40.
we know that
The measure of the interior angle is the half sum of the arcs comprising it and its opposite
so
m∠CED=
see the attached figure with letters to better understand the problem
° ------> by central angle
° ------> by central angle
Substitute the values in the formula above
m∠CED=
m∠CED=
m∠CED=
°
therefore
<u>the answer is</u>
m∠CED=
°
Using the distributive law:-
this = sqrt 14 sqrt 12 + sqrt 14 sqrt 7 - sqrt 3 sqrt 12 - sqrt 3 sqrt 7
= sqrt1 68 + sqrt 91 - sqrt 36 - sqrt 21
= sqrt 168 + sqrt 91 - sqrt21 - 6
