Answer:
option c is incorrect
because the value of tan B will be perpendicular/base
so tan B=5/12.

Answer:
13
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [2, 6 ]
f(b) = f(6) = 6² + 5(6) - 8 = 36 + 30 - 8 = 58
f(a) = f(2) = 2² + 5(2) - 8 = 4 + 10 - 8 = 6
Hence
average rate of change =
=
= 13
Not sure about the whole of part A, but the point labeled T is called an outlier or an anomaly.
Part B: There is a weak positive correlation. The higher the test scores, the higher the number of hours they exercise.
Well we know that A+B+C=180
and we know that A=45 and B=90
so together there 135
180-135=45
so C=45
now we also know that a straight line is 180 degrees so 180-45 =135(angle f)
135+15(angle e)=150
180-150=30
so angle d=30
