Answer:
40 degrees
Step-by-step explanation:
Because Angle RST is bisected by ray SU it is then split into two even angles and the resulting two angles will be 40 degrees apiece.
Find the mean of the following data: 10, 16, 15, 14, 8, 21, 10, 5, 19, 18, 4, 5, 16, 12, 10, 9

Answer:
12
Step-by-step explanation:
add all them together, then divide by the amt. of numbers there are.
Recall the fundamental rule of trig:
So, there exists an angle 
such that
if and only if
Working out the numbers, we get
So, there doesn't exist a number such that
f(x) is concave down on an interval I if all of the tangents to the curve on I are above the graph of f(x)
Total students 5+16+42+22+5 = 90
0-1's probability is 5 / 90 = 5.5% about
2-3's probability is 16 / 90 = 17.7% about
4-5's probability is 42 / 60 = 46.6% about
6-7's probability is 22 / 90 = 24.4% about
8+'s probability is 5 / 90 = 5.5% about
