Step 1
Acording to the given information,
Let the number of students in math123 be ‘x’
So, according to question in math136 there are 20% more students than math 123.
Number of students in math 136=480
480=20100x+x
Step 2
Now solve the above equation.
480=20100x+x
480=120x100
480(100)120=x
400=x
Therefore, number of students in math123 are 400.

The rate of change of the volume of a snowball that is melting is proportional to the surface area of the snowball. Suppose the snowball is perfectly spherical. Then the volume (in centimeters cubed) of a ball of radius r centimeters is 43πr3. The surface area is 4πr2.Set up the differential equation for how r is changing. Then, suppose that at time t=0 minutes, the radius is 10 centimeters. After 5 minutes, the radius is 8 centimeters. At what time t will the snowball be completely melted.

B. G. Cosmos, a scientist, believes that the probability is 25 that aliens from an advanced civilization on Planet X are trying to communicate with us by sending high-frequency signals to Earth. By using sophisticated equipment, Cosmos hopes to pick up these signals. The manufacturer of the equipment, Trekee, Inc., claims that if aliens are indeed sending signals, the probability that the equipment will detect them is 35. However, if aliens are not sending signals, the probability that the equipment will seem to detect such signals is 110. If the equipment detects signals, what is the probability that aliens are actually sending them?

Classify each of the studies as either descriptive or inferential. Explain your answers. In an article titled “Teaching and Assessing Information Literacy in a Geography Program” (Journal of Geography, Vol. 104, No. 1, pp. 17-23), Dr. M. Kimsey and S. Lynn Cameron reported results from an on-line assessment instrument given to senior geography students at one institution of higher learning. The results for level of performance of 22 senior geography majors in 2003 and 29 senior geography majors in 2004 are presented in the following table.
