Find the pressure exerted on a person by a few plastic blocks of total mass 42 kg, the bottom of which in contact with the person has an area of 840 cm2.
10)adding numbers
Victor has an array of size n.He loves to play with these n numbers.each time he plays with them ,he picks up any two consecutive numbers and adds them. on adding both numbers,it costs him K*(sum of both numbers).
Find the minimum cost of adding all the numbers in the array.
i/p1:size of array
i/p2:elements of array
i/p3:value of K
o/p:return the maximum cost of adding all the numbers of the array.
Ex1:
i/p1:3
i/p2:{1,2,3}
i/p3:2
o/p:18
explanation: There are multiple ways of adding the numbers of an array.
The first way is:1+2=3 cost of adding is 2*3=6.
3+3=6 cost ofadding is 2*6=12
o/p: there are other ways as well,but minimum cost is 18
ex2:
i/p1:4
i/p2:{4,5,6,7}
i/p3:3
o/p:132
explanation:
for minimum cost ,
4+5=9 cost of adding is 3*9=27
6+7=13 cost of adding is 3*13=39
9+13=cost of adding is 3*22=66
Therefore cost is 27+39+66=132

What happens to amylose starch that is not fully hydrolyzed in the small intestine? What might be the clinical consequence?
Medical literature tells us that our blood is mainly composed of red and white blood cells corpuscles and a normal human body must average 7250/mm³ of white blood cells counts. If a sample of 15 individuals chosen at random from a certain place has an average of 4850/mm³ with a standard deviation of 2500/mm³ would you say that the people in that place have low white blood cell counts?
a. Formulate the null and alternative hypothesis in sentence and in symbol
b. Determine what test statistic to use
c. Compute the test statistic
d. Final answer
