Answer:
B) 14
Step-by-step explanation:
1/5 + 1/3 = x (don't worry, it's not algebra, I'm just using x as an example)
The common denominator is 15, so you multiply 5 by 3 = 15 and 1 by 3 = 3,
3/15 = 1/5
Then, multiply 3 by 5 = 15 and then 1 by 5 = 5, so it's
5/15 = 1/3
5/15 + 3/15 = 8/15 and then multiply 15 by 2 = 30 (number of students) and because you multiplied 15 by 2, you also multiply 8 by 2 = 16
So it is now 16/30, so you do 30-16 which is 14.
14 students chose Station M (doesn't sound like a good station).
Whoo! Let's go! (I'll stop being cringy now).
To calculate it, first order your data points from least to greatest, then determine your first and third quartile positions by using the formulas (N+1)/4 and 3*(N+1)/4 respectively, where N is the number of points in the data set.
after you do that then say IQ=Q3-Q1
The answer is <span>2.25
You could multiply 0.5 by 72, then by 36, then by 18, and so on, until you found the 6th term.

Answer:
Originally
The number of coins in the first box was
The number of coins in the second box was
Finally
The number of coins in the first box is
The number of coins in the second box is
Step-by-step explanation:
Let
x-----> number of coins in the first box originally
y-----> number of coins in the second box originally
we know that
-----> equation A
-----> equation B
substitute equation A in equation B
Find the value of x
therefore
Originally
The number of coins in the first box was
The number of coins in the second box was
Finally
The number of coins in the first box is
The number of coins in the second box is
The answer is "y = ⁵/₄x + 10".
