Set sin x to a variable, i.e. u
u^2-u-2/u-2.
Factor:
(u-2)(u+1)/(u-2)
Simplify by canceling the u-2s...
leaving u+1. Since we substituted u for sin x...
the answer is A. sin x + 1
If my calculations are right (please double check) the answer is C.
The probability that Andrew has heart disease is 0.9. Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it?
Answer: The probability that Andrew has heart disease
Also we know that the accuracy rate of test or
The given two events are independent.
Therefore, the probability that Andrew has heart disease and the test accurately predicts it
Answer: 4955.30
Step-by-step explanation:
F = P (1+i)^n
F = $4000 (1+.055)^4
F = $4955.2986
Which will be 4955.30
