The third tree diagram is correct.
The probabilities for the first draw are 3/7 for green and 4/7 for red.
If you draw a green pear first, then your probabilities for the second pear would be 2/6 for green and 4/6 for red (since it is done without replacement, the number of pears to choose from changes).
If you draw a red pear first, then your probabilities for the second pear would be 3/6 for green and 3/6 for red.
Answer:
complementary angles, x=19
Step-by-step explanation:
since the two parts of the angle add up to 90, they are complementary angles.
you can find x by adding them and setting it equal to 90:
3x-2+2x-3 = 90
5x-5 = 90
5x = 95
x = 19
Symbol i we call imaginary unit =>
This is basic
i^2= i * i = -1
i^3= i^2 * i = -1 * i = - i
i^4= i^3 * i = -i * i = - (i * i )=- (i^2)= - (-1) = 1
i^5= i^4 * i = 1 * i = i
i^6= i^5 * i = i * i = i^2 = -1
i^7= i^6 * i = -1 * i = - i
i^8= i^7 * i = -i * i = -(i * i)= -( i^2)= - (-1) = 1
You have all you need.
You conclude which simplifications of the power i are correct.
Good luck!!!!
