Use the method of disks/rings to determine the volume of the solid obtained by rotating the region bounded by y=2x^2 and y=x^3 about the x-axis.
- If a student randomly guesses at five multiple-choice questions, find the probability that the student gets exactly three correct. Each question has five possible choices.
Two electric train A and B leave the same station on parallel rail line train A start at rest with a uniform acceleration of 0.2m/s2 and attain a speed of 45km/h and maintain this speed at constant rate after ward . the train B leave the station 1 minute after train A has left and move with uniform acceleration of 0.4m/s2 to attain a maximum speed of 72 km/h. If train B maintain the speed of 72km/h determine the time it will over take train A
a chip is placed at room temperature of 40°c after minutes its temperature changes from 80c to 60c the proportionallity constant in case is k=0.05 ln2 find temperture of chip after 40 minute.

Minimum and Maximum array entry
With a function that take as parameters a one dimensional array and
the capacity of the array. Your function has to find the minimum and
maximum entry in a one dimensional array. Write a driver program that
reads array values and finds the minimum and maximum entry using your
function.
Sample Input/Output:
Enter a no. of array elements: 5
Array[1]: 20
Array[2]: 80
Array[3]: 90
Array[4]: -23
Array[5]: 70
Minimum Array Entry: -23
Maximum Array Entry: 90
Left-tailed test, variance unknown, 𝛼 = 0.01, n = 23
A population consists of the five numbers 2, 3, 6, 8, and 11.
