quick answer of a boy is running on a straight road.He run towards north in 2 minutes and 10 seconds and then turn back and runs 200m in one minute.Calculate his average speed and magnitude of average velocity during first 2 minutes and 10 seconds and his average speed and mag...

286.956 gallons! 70 - (40% of 70) = 42 = wasted fuel set up a proportion 70/42 = 478.26/x x= 286.956 im pretty sure thats how u do it...but not postivie...so check w. other resources!!!
Prealgebra
so 1/5 of 40 is just 1/5 times 40 which equals 8.
Prealgebra
Rule # one = When you see the percent sign its over 100! so x%=x/100 Rule # 2 = In word problems, when u see the word "of" it means multiplication symbol...well not in all cases but in most cases especially when dealing w. percent stuff. so 25% of 162 means (25/100) ...

You have the mean 550 which is in the center of the normal distribution curve. and standard deviation is 110 which is how far the score is away from the mean. The question is asking you for 68.26, 95.44 and 99.74 percents and is demonstrated by the emperical rule that 68.26% i...

dependent variable is what you dont know b4 the experiment and independent is what you know b4 the experiment. so dependent variable is the time.... and independent variable is the measure of its temperature for ever 2 mins.... and I would prolly use a line graph to show the d...
statistics
Idk how to do a but for part b just use the emperical formula i think? except the numbers r kinda funky....so for 68.26 it wud be between 240 and 460, for 95.44 it wud be 130 and 570, and for 99.74 it wud be 20 and 680!

haha its aight......shud have used instead of </b? :D

oo I c it...my bad. Thnx 4 explain reiny! ._.
