Describe how to plot -3 3/4 on a number line?
2 answers:
On the number line, negative numbers go to the left. Since -3 3/4 is negative, go 3 spaces to the left.
When plotting a fraction or decimal on a number line, you need to estimate. If there are half marks in between the numbers, plot the point near the half mark. If it's -3 3/4, count 3 spaces, then go to the half mark of -3 to -4, and plot the 3/4 in between the -3 and -4 half mark. If there is no half mark, place it near the -4 mark.
The red line represents the half mark, the blue line represents where the point would go. Notice how when negative, the numbers go higher as they go left.

Answer:
13, 14, 15, 16
Step-by-step explanation:
Call the first number n. Then the next three consecutive numbers (assuming integers) are n + 1, n + 2, n + 3.
The mean is the total of the numbers divided by how many there are.
Simplify and multiply by 4.
The first number is 13.
The median is 14.5, halfway between the "middle" numbers 14 and 15. This is just a check; no additional equation is necessary.
