The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is
aniked [119]

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

Two roommates share a dorm in Richards Hall, The probability that Roommate A is doing homework on a Friday night is .3. The prob
bixtya [17]

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:

P(A) = P(a) + P(A \cap B)

In which P(a) is the probability that only the roommate A is doing homework and P(A \cap B) is the probability that both student A and student B are doing homework.

We also have that:

P(B) = P(b) + P(A \cap B)

The problem states that

The probability that Roommate A is doing homework on a Friday night is .3. So P(A) = 0.3.

The probability that Roommate B is doing homework on a Friday night is .4. So P(B) = 0.4

The probability that both roommates are doing homework on a Friday night is .2. So P(A \cap B) = 0.2

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:

P = P(a) + P(b) + P(A \cap B)

We have that

P(A) = P(a) + P(A \cap B)

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

P(A) = P(a) + P(A \cap B)

0.3 = P(a) + 0.2

P(a) = 0.1

Also

P(B) = P(b) + P(A \cap B)

0.4 = P(b) + 0.2

P(b) = 0.2

So:

P = P(a) + P(b) + P(A \cap B)

P = 0.1 + 0.2 + 0.2

P = 0.5

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