An aircraft has a mass of 509 000 kg. The total force from its jet engine is 800 000 N. What is it's acceleration?
1. The average score in the entrance examination in Mathematics at Sto.
Rosario National High School is 80 with a standard deviation of 10.A
random of 40 students was taken from this year's examinees and
was found to have a mean score of 84.
Is there a significant difference between the known mean and the
sample mean? Test at a= 0.05
Solution :
Step 1. H0: = 80 : There is no significant difference
hypothesized and the sample mean.
H1: "\\neq" 80 :
Step 2. Level of significance. a = 0.05.
Step 3. two tailed test, find the critical value. Zt =
4. Compute the test-statistic value:
5. Step :
6. Conclusion:
Differentiate between compiler and linker?
Write a Program that generates the following output:
10
20
19
Use an Integer constant for the 10, an arithmetic assignment operator to generate
the 20, and a decrement operator to generate the 19.

.What is Quantity Theory of Money?
Create an abstract class MathSymbol may provide a pure virtual function doOperation(), and create two more classes Plus and Minus implement doOperation() to provide concrete implementations of addition in Plus class and subtraction in Minus class.
Given a set of 'n' elements and 'r', write a generic function (Numbers and characters) to right shift the set of elements by 'r' position . If the elements are moved to the position that is greater than ‘n’ then wrap the shift process to the beginning of the collection.
For example, if the set of five elements are 1,7,8,9,12 and value of 'r' is 3 then the set of elements would be 8, 9, 12, 1, 7.
