I would write a proportion, I can't use a fraction bar so they will just be on top of each other:
Blueberry Muffins 6
Apple Muffins 5
For every 6 Blueberry muffins there are 5 apple muffins (dozens)
So when he makes 16 blueberry muffins (dozens)
You write it next to the '6' because it's talking about blueberry muffin dozens.
The proportion now:
Blueberry Muffins 6 16
Apple Muffins 5 x
To find x, or the number of apple muffin dozens, you multiply 16 * 5, which is
80.
Then divide by 6.
80/6= 13.333
You can't have .333 of a dozen, so round it to 13.
***ANSWER***
He prepared 13 Apple muffin dozens.
Hope this helped <3
Answer:

Step-by-step explanation:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.To calculate combinations the below formula is used:

where
represents the total number of items and
represent the number of items being chosen at a time. The '!' represents factorial function which is the product of all integers equal to and less than the given integer. This can be calculated manually using the formula or by using the nCr function on a scientific calculator.
Thus, the number of ways to select 2 freshmen girls (2FG) and 3 freshmen boys (3FB) can be determined. The number of ways to select 5 students (5S) can be determined in the same way.



The probability of selecting 2 freshmen girls (2FG) and 3 freshmen boys (3FB) when selecting 5 students out of 30 is given as below:

Answer:
10y³
Step-by-step explanation:
y appears 3 times.
Which means y is multiplied by itself 3 times.
Then, simplify 5 x 2, which is 10, then put y3 after 10.
When using scientific notation, you only want one number to be in front of the decimal place. If you have to make the number smaller, then the 10^nth power will be positive. If you have to make the number bigger, then 10^nth power will be negative. Example:
0.54 --> 5.4 * 10^-1
35 --> 3.5 * 10^1
The value of n depends on how many spaces the decimal point needs to be moved. For your question, putting 23 in scientific notation would look like this:
23 --> 2.3 * 10^1
