The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation
F=9/5 C+32
1.In the Sahara desert, temperatures often reach 50 degrees Celsius. How many degrees Fahrenheit is this?

2.In parts of Alaska, the temperatures can reach -60 degrees Fahrenheit. How many degrees Celsius is this?

3.There is one temperature where the degrees Fahrenheit and degrees Celsius are the same, so that C=F. Use the expression from the equation, where F is expressed in terms of C, to solve for this temperature.

The temperatures are in 50° Celsius, -60° Celsius and  -40° Celsius when the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit respectively.

Temperature is a measurement of an object or material's warmth or coldness and an expression of thermal energy.

Given, the conversion expression of degrees Fahrenheit to degree Celsius.

The expression is,

F = (9/5)C + 32

For the option 1,

C = 50° Celsius

Then F = 9 x 50/5 + 32

           = 90 +32

           = 122° Fahrenheit

For the option 2,

C = -60° Celsius

Then F =  9 x -60/5 + 32

           = -108 + 32

            = -76° Fahrenheit

For the option 3,

C = F

Then F = 9F / 5 +32

         F - 9F/5 = 32

         -4F / 5 = 32

           F = -160/4

           F = -40° Celsius.

Therefore, the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit when the temperatures are in 50° Celsius, -60° Celsius and  -40° Celsius respectively.

Which of the following expressions would give you the greatest quotient (answer to the division problem)?

In a laboratory experiment, two mice will be placed in a simple maze with one decision point where a mouse can turn either left (L) or right (R). When the first mouse arrives at the decision point, the direction it chooses is recorded. Then, the process is repeated for the second mouse.

The tree diagram should be drawn where the first stage represents the decision made by the first mouse and the second stage represents the decision made by the second mouse.

Determine all four possible decision outcomes for the two mice.


Using the information from the previous problem, answer the following question.

If the probability of turning left is 0.5 and the probability of turning right is 0.5 for each mouse, what is the probability that only one of the two mice will turn left?
