Answer:
240000
You have you multiply 40*6,000=240000. So that is your answer.
Step-by-step explanation:
We are told that for a large data set of a average student grades, the third quartile Q3 is found 78.5.
Since we know that third quartile represents the number such that 75% of the data is less than this number. Third quartile is the middle value between median and the highest value of a data set. Third quartile is also known as upper quartile. Third quartile splits lower 75% data from highest 25% of data.
Therefore, third quartile represents that 75% of student grades are less than 78.5 and 25% of students grades are greater than 78.5.
So first you would put these over a common denominator which is 96. You get this by multiplying by 9 and what you do to the denominator you must do to the numerator so you then get 45/96 and 63/96. Pelicans=45/96. Woodpeckers=63/96
So first we want to distribute. (#1)
So, using the distributive property, we can:
5 * 3x - 2y * 5 + 2x + 2 * 2y - 3 * 3x - 3 * 2y
or
15x - 10y + 2x + 4y - 9x - 6y
Now just combine like terms
8x -12y
So for #1 it should be a.
#2: 2x - 3 + 3x - 5
Combine Like Terms:
2x + 3x - 3 - 5
5x - 8
So it should be b.
