Answer: Concealment of a particular group from one or more individuals
Step-by-step explanation:
Blinding is a term used to conceal a particular group from one or more individuals who are involved a clinical study. Blinding is used in this study to evaluate the placebos. This was important in this study because the treatment being done by echinacea was no being effective. So in order to gain good results and to see the actual results, blinding was done.
Step-by-step explanation:
Write the prime factorization of each term:
9r⁵s = 3² × r⁵ × s
6r⁴s² = 2 × 3 × r⁴ × s²
12r²s = 2² × 3 × r² × s
The greatest common factor will have all the common factors raised to their lowest exponent.
So all three terms have 3, r, and s as factors. The lowest exponent of 3 is 1. The lowest exponent of r is 2. The lowest exponent of s is 1.
GCF = 3 × r² × s
GCF = 3r²s
Factor out the GCF:
9r⁵s + 6r⁴s² − 12r²s
3r²s (3r³ + 2r²s − 4)
Answer:
(-340)/231
Step-by-step explanation:
Simplify the following:
((-34)/33)/(7/10)
Multiply the numerator by the reciprocal of the denominator, ((-34)/33)/(7/10) = (-34)/33×10/7:
(-34×10)/(33×7)
33×7 = 231:
(-34×10)/231
-34×10 = -340:
Answer: (-340)/231
