Answer:
=98m^2
Step-by-step explanation:
11×4=44
9×6=54
44+54=98
=98m^2
Answer:
Step-by-step explanation8:
B = -16
m = (-15-(-16))/18-0 = 1/18
y= 1/18x - 16
6 lbs 2 oz. 6 lbs = ?oz
6×16 =96oz+2 oz =98oz David's weight
5lbs 5oz 5lbs=?oz
5×16=80oz+5oz=85oz Daniel's weight
98oz+85oz=183oz (c)
29 + 29 + 13 = 71
The range of possible times in seconds for x is 28:30 - 29:29. Similarly for y.
The range of possible times for z is 12:30 - 13:29
The range of possible values for x + y + z = 69:30 - 72:27 which is 178 seconds long
To be recorded as 72 minutes the sum would be in the range 71:30 - 72:27 which is 58 seconds long
P(result recorded as 72 min) = 58/178
If you simply used the ranges [28.5, 29.5) [28.5, 29.5) and [12.5, 13.5)
then the sum would be in the range [69.5, 72.5)
and P(result recorded as 72 min) = 60 seconds / 180 seconds = 1/3
Using discrete times in seconds gives a slightly different answer but is also much harder to understand.
