Answer:
1st: 116°
2nd: 64°
Step-by-step explanation:
Supplementary angles add up to 180 degrees. We can make the first supplementary angle be represented by: 2x - 12 and the second supp. angle be represented by x.
Make both of these expressions add up to 180.
(2x - 12) + (x) = 180
Combine like terms.
3x - 12 = 180
Add 12 to both sides.
3x = 192
Divide both sides by 3.
x = 64
Substitute 64 for x into the first supp. angle's expression.
2(64) - 12 = 116
The first supp. angle is 116 degrees and the second is 64 degrees.

Answer:
The joint probability distribution of X and Y is shown below.
Step-by-step explanation:
The distributions of X and of Y are described as follows:
X : 0 1
P (X) : 0.23 0.77
Y : 1 2 3
P (Y) : 0.40 0.22 0.38
It is provided that X and Y are independent.
That is:
P (X ∩ Y) = P (X) × P (Y)
Compute the joint probability distribution of X and Y as follows:
X 0 1
<u>Y </u>
1 0.9200 0.3080
2 0.0506 0.1694
3 0.0874 0.2926
172/387 = 4/t
Let t = time to travel 387 miles
172t = 4(387)
172t = 1548
t = 1548/172
t = 9
Answer: 9 hours
