Answer:

y=-2,500x+19,000

Step-by-step explanation:

To write the equation, use y=mx+b. Look at the graph and identify m and b. b is the y-intercept and where the line crosses on the y-axis. Here it is 19,000.

To find the slope m, count the units from one point to another on the line. Identify the points on the line that go through grid line intersections. Count up/down then count right to form the ratio.

From point (0,19,000) to (2, 14,000). These points are -5,000 vertically and 2 horizontally. It forms the ratio -5,000/2 = -2,500. This is m.

So y=-2,500x+19,000

Find the median of the data.<br><br> 12, 10, 14, 9, 8, 9, 15, 15
hram777 [196]

Answer:

11

Step-by-step explanation:

First, order the numbers in the given set from least to greatest:

8 , 9 , 9 , 10 , 12 , 14 , 15 , 15

The median is the number found in the middle of the given set. If the amount of numbers in the set are even (as in this case), then you will find the mean of the two middle numbers.

In this case, the middle numbers are 10 & 12:

Find the mean. The mean is found by adding all the numbers together and dividing by the amount of numbers there is:

(10 + 12)/2 = (22)/2 = 11

11 is your median.

Which of the following is equivalent to the complex number i^17
Anton [14]

Answer:

Step-by-step explanation:

It’s a repeating pattern.

i² = -1

i³ =(i²)i = (-1)i = -i

i⁴ = i³i = -i² = 1

i⁵ = (i⁴)i = (1)i = i

i⁶ = i⁵i = i² = -1

...

i¹⁷ = i
