Answer:
Option A, 50 degrees
Step-by-step explanation:
<u>Step 1: Estimate this angle</u>
<em>Option A, works because looks about the size of 50 degrees</em>
Option B, doesn't work because it is not more than a right angle.
Option C, doesn't work because it is not an obtuse angle.
Option D, doesn't work because there is no way it is 15.
Answer: Option A, 50 degrees

Answer:
r = - 3
Step-by-step explanation:
To find the common ratio r, divide consecutive terms
- 9 ÷ 3 = - 3
27 ÷ - 9 = - 3
- 81 ÷ 27 = - 3
Thus common ratio = - 3
Answer:
0.11069
Step-by-step explanation:
We will assume that the trains pass by his house following a uniform distribution with values between 0 and 24. The probability of a train passing on a 9-hour time period is 9/24 = 3/8 = 0.375. Lets call Y the amount of trains passing by his house during that 9-hour period. Y follows a Binomail distribution with parameters 22 and 0.375.
P(Y ≤ 5) = P(Y = 0) + P(Y=1) + P(Y=2) + P(Y=3) + P(Y=4) + P(Y=5) =
I hope that works for you!
