Answer: 250 miles
Step-by-step explanation:
I am not sure what grade level you are, but this is how it is done in college.
I hope it can give you an idea and be of some help.
First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.
150 minutes x <u> 1 hour </u> x<u> 100 miles </u>= 250 miles
60 mins. 1 hour
Y = -2x - 2. Slope here is -2. A parallel line will have the same slope.
y = mx + b
slope(m) = -2
(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = -2(3) + b
4 = - 6 + b
4 + 6 = b
10 = b
so ur parallel equation is : y = -2x + 10
4 is the x1 value, -8 is the y2 value, 8 is the x2 value, and 5 is the y2 value.
The standard deviation is the square root of the variance
so if the variance is 256, then the standard deviation is : sqrt 256 = 16 <==
