Answer:
heh...
Step-by-step explanation:
3cot²x - 5cotx = -2
Lets pretend cotx = t
3t² - 5t = -2
3t² - 5t + 2 = 0
factor polynomial
(3t-2)(t-1) = 0
3t-2 = 0
t-1 = 0
then "t" which is also cotx is equal to 1 or 2/3
Answer:
The probability that the woman selected does not have red/green color blindness is 0.9945.
Step-by-step explanation:
Let <em>X</em> = a woman has red/green color blindness.
It is provided that, in a certain group of women the rate of red/green color blindness is <em>P</em> (<em>X</em>) = 0.0055.
A complement of an event <em>E</em>, is defined as the event of not <em>E</em>.
The probability of complement of an event <em>E</em> is:

Compute the probability that the woman selected does not have red/green color blindness as follows:

Thus, the probability of the complement of the event of a woman having red/green color blindness is 0.9945.
G(9)=10-4*9=10-36= - 26
g(-2)=10-4*(-2)=10+8=18
g(9)+g(-2)= -26 + 18
g(9)+g(-2)= - 8
