A line never has end points. It goes forever in both directions. A segment always has points. A ray has one point and goes forever in one direction. The answer is always. Hope this helps! ;)

Graph the line.<br> y - 2 = -3(x + 3)

Tatiana [17]

Answer:

see below

Step-by-step explanation:

The equation is in point-slope form, so you know the line goes through the point (x, y) = (-3, 2) and it has a slope of -3. The slope tells you the line goes down 3 units for each 2 units to the right.

Work out the surface area of a cube of edge 2m

BlackZzzverrR [31]

- - If we have a edge area of: 2m

Then we can work out to find the surface area:

$6s^2$ = Surface area.

So we plug in and solve and we get:

Surface area= $24m^2$

A factory dumps an average of 2.43 tons of pollutants into a river every week. if the standard deviation is 0.88 tons, what is t

vovikov84 [41]

25.8%
First, determine how many standard deviations from the norm that 3 tons are. So:
(3 - 2.43) / 0.88 = 0.57/0.88 = 0.647727273
So 3 tons would be 0.647727273 deviations from the norm. Now using a standard normal table, lookup the value 0.65 (the table I'm using has z-values to only 2 decimal places, so I rounded the z-value I got from 0.647727273 to 0.65). The value I got is 0.24215. Now this value is the probability of getting a value between the mean and the z-score. What I want is the probability of getting that z-score and anything higher. So subtract the value from 0.5, so 0.5 - 0.24215 = 0.25785 = 25.785%
So the probability that more than 3 tons will be dumped in a week is 25.8%
