Answer:
y = -5/4x - 7
Step-by-step explanation:
First, find the slope:
3 - -7 / -8 - 0 = -5/4
Put it in point slope form:
y + 7 = -5/4(x-0)
y + 7 = -5/4x
0.76
0.48, 0.66, 1.02, 0.82, 0.7, 0.94
Organize the numbers from least to greatest.
0.48, 0.66, 0.7, 0.82, 0.94, 1.02
Then find the middle (Median is the middle).
0.48, 0.66, 0.7, |?| 0.82, 0.94, 1.02
Take the two numbers closest to the middle. Add them.
0.7 + 0.82
= 1.52
Divide that with 2.
= 0.76
He starts on the 1st floor. He then goes up 18 floors:
1 + 18 = 19
He took the stairwell down 3 floors
19 - 3 = 16
He then takes the elevator down 8 floors
16 - 8 = 8
He then takes the stairwell up 5 floors for his afternoon meeting
8 + 5 = 13
