Answer:
31 degrees
Step-by-step explanation:
In order to solve this problem, it's essential to know that all the angles in a triangle add up to 180 degrees.
1. Add 54 and 95. This equals 149.
2. Subtract 149 from 180. This equals 31, which is your answer for that angle.
*When you're looking at a problem like this, sometimes it helps me to first determine if it's larger or smaller than a right angle so I know if my answer should be larger or smaller than 90 degrees.
The probability that at least one of the calculators is defective is : 0.725
<h3>What is probability?</h3>
Probability is the likelihood of an event happening or not.
if there is certainty that the event would happen probability is 1.
Analysis:
probability = required outcome/possible outcome
for 33 good calculators and 12 defective calculators, total calculators = 45
4 calculators were chosen, possible outcome = 45C4 = 148995
Required outcome = 33C3 . 12C1 + 33C2 . 12C2 + 33C1 . 12C3 + 33C0 . 12C4
= 65472 + 34848 + 7260 + 495 = 108075
Probability = 108075/148995 = 0.725
