K=-1 or k=5
either quantity could equal zero, so put each quantity equal to zero and solve for k.
hope this helps :)
Answer:
B
Step-by-step explanation:
What is required is the probability of selecting one orange and one black kitten.
outcomes ( 1 O and 1B) = 4C1 * 5C1
Total outcomes = 9C2
Note: the order of color does not matter it is simply a matter of selection hence only combinations are made NOT permutations.
P (1O and 1B) = outcomes ( 1 O and 1B) / Total outcomes
P (1O and 1B) = (4C1 * 5C4) / 9C2 = 0.5556
The answer is 120 degrees I hope this helps
There is many ways to do this but i did it this way.
180-123.75= 56.25
56.25/5=11.25
=11.25
