Hey, I am able to help you today :)

Step 1 - Simplify:
420x^2 - 18 = 2082

Step 2 - Add 18 to both sides:
420x^2 = 2082 + 18

Step 3 - Simplify 2082 + 18 to 2100:
420x^2 = 2100

Step 4 - Divide both sides by 420:
x^2 = 2100/420

Step 5 - Simplify 2100/420 to 5
x^2 = 5

Step 6 - Simplify:
x = 5

Step 7 - Check your answer:
10 x 42 x 5 - 18 =2082

Hope this helps you today :)

Marysya12 [62]

Answer:

d.)The experimental units are assigned randomly to exactly one control group and one or more treatment groups

Step-by-step explanation:

Completely randomized design can be regarded as a type of experimental design in which the experimental units are assigned randomly for different treatments. This experimental design is utilized in cases whereby experimental units are seen to be “uniform" this implies that no uncontrolled factor in the experiment. completely randomized designs are engaged in studying effects of one primary factor by ignoring other nuisance variables it perform comparison of values of a response variable taking into account of the different levels of that primary factor. It should be noted that in completely random design, the experimental units are assigned randomly to exactly one control group and one or more treatment groups
