If 3/5 = a/m and m−a = 80, then what is the value of m? (a) 2 (b) 20 (c) 80 (d) 120 (e) 200

E

Step-by-step explanation:

3/5=a/m 3m/5=a

m-3m/5=80

2m/5=80

m=200

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
