Answer:
h(a + 2) = 4a + 3
Step-by-step explanation:
∵ h(x) = 4x - 5
∴ h(a + 2) = 4(a + 2) - 5
∴ h(a + 2) = 4a + 8 - 5 = 4a + 3
17. Yes!! SAS theorem

20. I don’t think so
Answer: A because it goes from (0,infinity) so all positive real numbers
Answer:
a) What is the probability that we will pick a blue ball?
there is a 50% chance that urn 1 will be selected and the possibility of a blue ball is 3/4 x 0.5 = 1.5/4
there is also a 50% chance that urn 2 will be selected and the possibility of a blue ball is 2/4 x 0.5 = 1/4
the probability of choosing a blue ball = 1.5/4 + 1/4 = 2.5/4 or 5/8
b) If we picked a blue ball, what is the probability that the selected urn was urn-1?
there are 5 blue balls in total, and 3 of them come from urn 1
c) Suppose we picked a blue ball. If we randomly pick one additional ball from the same urn, what is the probability that we pick a red ball?
there is a 50% chance that urn 1 will be selected, and the possibility of a red ball after a blue ball is 1/3 x 0.5 = 0.5/3
there is also a 50% chance that urn 2 will be selected and the possibility of a red ball after a blue ball is 2/3 x 0.5 = 1/3
the possibility of choosing a red ball after a blue ball = 0.5/3 + 1/3 = 1.5/3 = 1/2
