Answer:
<em>The percent change in enrollment at Main Middle School was about 20%</em>
Step-by-step explanation:
<u>Percentages</u>
There was a change of enrollments in the 7th grade at Main Middle School from 612 to 489 due to openings of a new school.
The change in the number of enrollments was 612 - 489 = 123.
To express it as a percentage, we divide by the original number and then multiply by 100:
The percent change in enrollment at Main Middle School was about 20%
Answer:
11/5 or 2.2
Step-by-step explanation:
To calculate the slope of a line, identify two points on that line, and use the slope formula:
y2 - y1/x2 - x1
(5) - (-6)/ (-4) - (-9)
(5) - (-6) = 11
(-4) - (-9) = 5
11/5 = 2.2
Answer:
- Put the numbers in order
- Cross off the high/low pairs
- Add the leftover numbers
- Divide the sum by 2
=================================================
Explanation:
The numbers sort to this
16, 18, 23, 24, 29, 30
Cross off the outer most values 16 and 30 to end up with this smaller set
18, 23, 24, 29
Then repeat to get this smaller set
23,24
We add up these numbers and divide the sum by 2
(23+24)/2 = 47/2 = 23.5
The median is 23.5
The last steps of adding and dividing by 2 only works if we have an even number of values in the original set.
(-x + 4) + (3x + 2)
= 2x + 6
Answer:
continuously
Step-by-step explanation:
The more compounding you have, the greater the yield. Obviously of the three, compounding continuously is the largest. In math, we used the mathematical constant "e" to compute continuous compounding.
