Answer:
x= 4/5
y= 2/5
Step-by-step explanation:
3x-y=2
2x+y=5
solve them so that they are in y=mx+b form
3x-y-3x=2-3x
-y= -3x+2
y= 3x -2
2x+y -2x= 2-2x
y= -2x+2
now use the substitution method to get your points
3x -2= -2x+2
3x -2+2= -2x+2+2
3x= -2x+4
3x+2x= -2x+4+2x
5x=4
x= 4/5
now substitute x into any of the 2 equations
y= 3x -2
y= 3(4/5) -2
y= 2 2/5 -2
y= 2/5
Hope this helped!
We have to deal with the distance in more detail
If the turtle is 11 times faster than the snail, the amount of distance he will cover is 11 times more.
d/(360 - d) = 1/11
11d = 360 - d
12d = 360
d = 30 The Snail covers 30 meters. The turtle covers 11*30 = 330 meters.
Answers
Rate of snail = 30 meters / 40 minutes = 3/4 meter / minute
Rate of turtle = 330 meters / 40 minutes = 8.25 meters / minute.
Answer:
And in the figure attached we see the limits with the percentages associated.
Step-by-step explanation:
For this case we know that the random variable of interest is the scores on a test given to all juniors in a school district follows a normal distribution with the following parameters:
For this case we know from the empirical rule that within one deviation from the mean we have approximately 68.2% of the data, within 2 deviations from the mean we have 95% and within 3 deviation 99.7%
We can find the limits and we got:
And in the figure attached we see the limits with the percentages associated.
