Mathematics
1 answer:
miss Akunina [59]3 years ago
3 0

Answer: 0

<u>Simplify both sides of the equation</u>

<u></u>25z^2-15z+2=25z^2-15z+2<u></u>

<u></u>

<u>Subtract 25z² from both sides</u>

<u></u>25z^2-15z+2-25z^2=25z^2-15z+2-25z^2<u></u>

<u></u>-15z+2=-15z+2<u></u>

<u></u>

<u>Add 15z to both sides</u>

<u></u>-15z+2+15z=-15z+2+15z<u></u>

<u></u>2=2<u></u>

<u></u>

<u>Subtract 2 from both sides</u>

<u></u>2-2=2-2<u></u>

<u></u>

Final Answer: 0=0

Which statement correctly compares the mean number of students for the data in the plots?
satela [25.4K]

Answer:

<em><u>"There are about 2 more students in each class at Oak Middle School than at Poplar Middle School."</u></em>

Step-by-step explanation:

We need to compute the mean for each.

<u>Poplar Middle School:</u>

Lets list the numbers

20,20,20,21,21,21,21,21,22,22,22,22,22,22,22,23,23,23,23,24

The average is sum of all divided by number of numbers, that will be:

435/20 = 21.75

<u>Oak Middle School:</u>

The numbers are:

20,21,21,22,22,23,23,23,23,24,24,24,25,25,26,26,27,27,28,29

The average is sum divided by number of numbers, that will be:

483/20 = 24.15

The difference in mean is:

24.15 - 21.75 = 2.4

We can say, that is about 2 more students in Oak Middle School, correct answer choice is "2nd answer choice" - <em><u>"There are about 2 more students in each class at Oak Middle School than at Poplar Middle School."</u></em>
