There are 3 methods to solve this. elimination substitution and graphing but i am going to use the elimination method.
x+2y=17
<u> x-y =2
</u> 0+3y =15 ( subtracted down to eliminate the x)( x-x=0, 2y-(-y)=3y, and 17-2=15)
3y=15 (divide both sides by 3 to solve for y)
y=5
<u>substitute the y=5 in any of the above equations and solve for x
ie... ( </u>meaning where you find y in the equation, u replace it with a 5)
it will be easier to solve for x in (x-y=2) so i will use that one.
x-(5)=2 ( add 5 on both sides to solve for x)
x=7
Answer:
"interquartile range", abbreviated "IQR", is just the width of the box in the box-and-whisker plot. ... The IQR tells how spread out the "middle" values are; it can also be used to tell when some of the other values are "too far" from the central value.
the gender of the kids does not matter so it can be discarded.
you add up how many boys and girls in the class to make a total of 50 kids
your 100% is 50
meaning 40% of 50 is 20
so if 20 kids took the bus to school then 30 did not take the bus.
