A machine tool operator thinks that fumes emitted in the workshop are instrumental in the low efficiency of the operators. She would like to prove that to

her supervisors through a research study. If you were her, how will you design this

experiment and this research study?

a) How will you follow the concepts of randomization, replication and local

control?

b) What will be Completely Randomised Design (CRD), Randomised Block

Design (RBD) and Latin Square Design (LSD) in this case?​

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

5/20 so 25%

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
