Answer:
<h2>r = 6</h2>
Step-by-step explanation:
18 - r = 12 <em>subtract 18 from both sides</em>
18 - 18 - r = 12 - 18
-r = -6 <em>change the signs</em>
r = 6
<em>Check</em>
18 - 6 = 12 <em>CORRECT</em>
Answer:
Option D) 0.92
Step-by-step explanation:
We are given the following probability distribution in the question:
x: 0 1 2 3 4 5
P(X): 0.78 0.14 0.03 0.01 0 0.04
We have to find the probability that a randomly selected student will be absent no more than one day.
Thus, we have to evaluate:
0.92 is the probability that a randomly selected student will be absent no more than one day.
Thus, the correct answer is
Option D) 0.92

Answer:
Step-by-step explanation:
x = 180 - 80 - 55 (Interior angles of a triangle add up to 180 degrees so if we need to find any unknown angle, we'll subtract all the other angles from 180)
x = 45 degrees
Answer: your answer will be (b) 0
