the table below shows the frequency of marks obtained by 40 students in a test marks:5,6,7,8,9,10 frequency: 8,x-1,x,10,6,5 if a student is selected at random, find the probability that he scored 6marks

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

21/58.
