Answer:
a-6
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
Pick any two points and use the slope function
m = (y2-y1)/(x2-x1)
m = ( -26 - -2)/(2 - -4)
= (-26+2)/(2+4)
- 24/6
- 4
Answer:
52.4 min
Step-by-step explanation:
100% of the times are between 49.2 min and 55.5 min.
48.8% of the times are between x and 55.5 min.
Write a proportion:
(55.5 − 49.2) / 1 = (55.5 − x) / 0.488
0.488 (55.5 − 49.2) = 55.5 − x
3.0744 = 55.5 − x
x = 52.4256
Rounded to the tenths place, the time is 52.4 min.
