What's the answer to b?

a. 6

b. 15

Step-by-step explanation:

We have two sets of fractions with one missing square in each of them and are asked to find the missing term.

Both of these questions can be answered with cross multiplication, fortunately we have enough information to do so.

A.

3/8 = ?/16

Multiply 3 and 16 :

48.

Now what times 8 equals 48?

6.

B.

32/24 * 20/?

Multiply 24 by 20 :

480.

Now what times 32 equals 480?

15

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

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
