Answer:
Rob's total debt to his father is calculated as: -$15 - $3 = -$18
Step-by-step explanation:
Initially, Rob borrows $15.
Then, he borrows an additional $3.
Expressing this with negative integers gives us
-15 - 3 = -18
Dolls = d
trains = t
8d + 10t = 150
I believe we can express it like that.
Answer:
Step-by-step explanation:
It has been established that the count of drivers traveling between a specific origin and destination in a certain time frame follows a Poisson distribution with a mean μ = 20 (as indicated in the article "Dynamic Ride Sharing: Theory and Practice"†).
a) 
b) 
c) 
d) 2 standard deviations = 2(20) = 40
Thus, this means the range for 2 standard deviations is
20-40, 20+40
which equates to (0,60)
