Hey there!!!
Given equation :
... - 3 ( 2x - y ) + 2y + 2 ( x + y )
... -6x + 3y + 2y + 2x + 2y
... -6x + 5y + 2x + 2y
... -4x + 7y
( or )
... 7y - 4x
Hope helps!
Answer:
P=2
Step-by-step explanation:
10-2.5(3.2)=P
By order of operations you would multiply 2.5 and 3.2 together giving you 8.
You would then subtract 10-8 giving you 2.
Answer: IQR = 16
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation
term
If the number of observations is even, then the median is observation and observations.
given n=3, middle term is '74'
In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
= 80-64
= 16
IQR = 16
Answer:
<em>For each horizontal foot, the roller coaster changes </em><em>6 feet</em><em> of height.</em>
Step-by-step explanation:
Across a horizontal distance of 25 feet, a roller coaster has a steep drop.
So the run is 25 feet.
The height of the roller coaster at the bottom of the drop is -150 feet. (Negative sign is given because it is measured from the top to bottom)
So the rise is 150 feet.
The slope of the roller coaster is,
![m=\dfrac{\text{Rise}}{\text{Run}}=\dfrac{150}{25}=6](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B%5Ctext%7BRise%7D%7D%7B%5Ctext%7BRun%7D%7D%3D%5Cdfrac%7B150%7D%7B25%7D%3D6)
Slope of 6 means, for 1 unit of run, the object has a rise of 6 units.
Therefore, for each horizontal foot, the roller coaster changes 6 feet of height.
