Answer:
10.50°C
Step-by-step explanation:
Given x = 2 + t , y = 1 + 1/2t where x and y are measured in centimeters. Also, the temperature function satisfies Tx(2, 2) = 9 and Ty(2, 2) = 3
The rate of change in temperature of the bug path can be expressed using the composite formula:
dT/dt = Tx(dx/dt) + Ty(dy/dt)
If x = 2+t; dx/dt = 1
If y = 1+12t; dy/dt = 1/2
Substituting the parameters gotten into dT/dt we will have;
dT/dt = 9(1)+3(1/2)
dT/dt = 9+1.5
dT/dt = 10.50°C/s
Hence the rate at which the temperature is rising along the bug's path is 10.50°C/s
D is the right answer bc I am smart
Answer:
There is a 50% probability that at least one roommate is doing homework this Friday night.
Step-by-step explanation:
This problem can be solved building the Venn Diagram of these probabilities.
I am going to say that P(A) is the probability that the roommate A is doing homework and P(B) is the probability that the roommate B is doing homework.
We have that:

In which P(a) is the probability that only the roommate A is doing homework and
is the probability that both student A and student B are doing homework.
We also have that:

The problem states that
The probability that Roommate A is doing homework on a Friday night is .3. So
.
The probability that Roommate B is doing homework on a Friday night is .4. So 
The probability that both roommates are doing homework on a Friday night is .2. So 
Find the probability that: At least one roommate is doing homework this Friday night
This is the probability that either only A is doing, either only B, or both. So:

We have that

We have P(A) and
, so we can find P(a)



Also



So:



There is a 50% probability that at least one roommate is doing homework this Friday night.
