Answer: Choice A</h3>
Why? Because the denominators are both the same at 2x+8. We can only add or subtract fractions when the denominators are the same. The general rule for adding fractions is
We have numerators A and B added together over a common denominator C. If we didn't have a common denominator, then we'd have to do a bit of algebraic manipulation to get both fractions to a common denominator. It doesn't have to be the lowest common denominator (LCD), though it's often more efficient that way.
Percent means per one-hundred....
48(p/100)=12
48p=1200
p=25%
So $12 off of a $48 item is 25% off.

Answer:
A. 16¾
Step-by-step explanation:
We will convert all the mixed fractions to improper fractions.
Monday, 5½ =
Wednesday, 6¾ =
Friday, 4½ =
Now, we will add all these fractions by taking the LCM of denominator.
The LCM of 2,4 and 2 is 4.
We get the following result after addition.
=
= hours
In mixed fraction it becomes 16¾ hours.
<span>A binomial distribution is the discrete probability distribution of the number of successes in a sequence of independent experiments, each asking a yes/no question, and each with an outcome that has a random variable containing single bit of information. So, an example would be A: Find the probability of selecting a red ball from a vase containing red, green, and yellow balls after selecting two yellow balls without replacement.</span>
