Answer:
a or b
Step-by-step explanation:
if I did the math right it's a but I tried another way and got b, so I'm sorry if that was no help at all
The ratio of a : b : c in its simplest form is 5 : 12 : 30 respectively
<h3>How to solve ratio?</h3>
- a : c = 1 : 6
- b : c = 2 : 5
So,
a / b = 1/6
b/c = 2/5
- lowest common multiple of c in both ratio
1/6 + 2/5
=(5 + 12) /30
a : b and b : c
= 5/30 and 12/30
Therefore,
a : b : c = 5 : 12 : 30

Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.
Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5
Therefore, we have:
Let x be the number calls that reach to live person.
We have to find 
Using the binomial probability distribution, we have:
Therefore, the probability that none of them reaches a live person is 0.3277

Answer:
<em>The measure of the angles is 45° and 135°</em>
Step-by-step explanation:
When two lines intersect, a linear pair of angles is formed. Two angles are said to be linear if they are adjacent, so a linear pair of angles must add up to 180 degrees.
Let's call x and y the two required angles. Knowing they form a linear pair:
x+y=180
We also know one angle is 1/3 of the other angle, thus:
x=y/3
Or, equivalently:
3x=y
Substituting y into the first equation:
x+3x=180
Simplifying:
4x=180
Solving:
x=180/4=45
The other angle is:
y=3x=3\cdot 45=135
Thus the measure of the angles is 45° and 135°
