Using an Empirical approach and the probability concept, it is found that there is a 7% probability that song will be played next.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. Using an Empirical approach, these number of outcomes are taken from <u>previous trials</u>.
In this problem, considering the previous 100 songs, the same song was played 7 times, hence:
p = 7/100 = 0.07.
There is a 7% probability that song will be played next.

You can factor -80 as
So, we have
The square root of a product is the product of the square roots:
Since and , we have
Estimate of discount: $4.50
total after discount: $18
hope this helps :)
edit: just saw the answer choices, the answer should be b.0.2
Answer:
25°
Step-by-step explanation:
∠1 = 180° - 155° = 25°
∠1 is the same as ∠5
So ∠5 = 25°

Just take it slow and easy, one small step at a time:
Write the problem : <u>4x + 2 = 7x - 8</u>
Add 8 to each side: 4x + 10 = 7x
Subtract 4x from each side: 10 = 3x
Divide each side by 3 : 10/3 = x
That wasn't so bad, was it ?
