To find the mean, add all the values together and divide by the number of values in the set.

1+2+3=6
6/3= 2
the mean is 2.

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. So.... 1 + 2 + 3 = 6 6/3 = 2 I hope you understood

Does somebody know the answer? If you can please explain

None of them are correct.
You have to isolate the variable by dividing each side by factors that don't contain the variable.
And when you do so you get a closed point starting at positive 8 and an extending ray to positive infinity and a closed point at -15 with a ray extending to negative infinity on the number line so none of them are correct.

A car traveled at a constant speed. The graph shows how far the car traveled, in miles, during a given amount of time, in hours.

snow_tiger [21]

Answer:

Step-by-step explanation:

A car traveled at a constant speed as shown in the graph.

Distance traveled is on the y-axis and duration of travel on the x-axis.

Point A(3.5, 210) shows,

Distance traveled = 210 miles

Time to travel = 3.5 hours

So the point (3.5, 210) shows the distance traveled by the car in 3.5 hours is 210 miles.

Slope of the line = speed of the car = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{210}{3.5}$

= 60 mph

Now we will find the speed of the car at another point B(1, 60).

If the speed of car is same as the point B as of point A, point B will lie on the graph.

Speed of the car at B(1, 60) = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{60}{1}$

= 60 mph

Hence, we can say that point B(1, 60) lies on the graph.
