What is the probability that Carol, the 44-year-old you’re considering for a 20-year policy, lives to be 64 years old? Note that this is a conditional probability. Another way of saying this is, “What is the probability that Carol turns 64 years old given that she turns 44 years old?” Carol is a non-Hispanic black female, so look in table 18.

The correct answer was given: Brain

d.(2,-1,-1)

step-by-step explanation:

-a+4b+2c=-8

3a+b-4c=9

b = -1

substitute b=-1 into the other equations

-a -4 +2c = -8

3a -1 -4c =9

multiply the first equation by 2 so we can eliminate c

-2a -8 +4c = -16

add this to the second equation

-2a -8 +4c = -16

3a -1 -4c =9

a -9 = -7

add 9 to each side

a-9+9 = -7+9

a =2

b=-1

now we need to find c

-a +4b +2c = -8

-2 -4 +2c = -8

-6+2c = -8

add 6 to each side

-6+6 +2c = -8+6

2c = -2

divide by 2

2c/2 = -2/2

c=-1

(2,-1,-1)

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
