On January 22 in 1943, the town of Spearfish, South Dakota, set the record for the world's fastest
temperature change.
At 7:30 a.m., the temperature was -4°F.
By 7:32 a.m., the temperature was 45 °F.
By 9:00 a.m. the same day, the temperature was 54 °F.
By 9:27 a.m., the temperature was -4 °F.
How many degrees did the temperature change each
minute from 7:30 to 7:32?
Make sure to show whether the change was positive or
negative.

P(x<10) =0

Step-by-step explanation:

M =1/μ

M= 1/15 =0.066667

X- Exp (0.066667)

Where: X is the random variable for number of days

P (X<x) = 1 - e^-mx

P(X - x) = 1 - e^-0.06666 x10

P(x<10) = 0
