(C) 32
Step-by-step explanation:
This is a problem of Permutation and Combination, not probability.
This clarification is given because most questions like this are on Probability and Statistics.
The researcher has recruited 8 participants and must divide them into two groups of 4 people each.
So there's:
GROUP A - Placebo Group
GROUP B - Experimental Group
Since the experiment is on humans - distinct objects - they will have distinct identities. Assume the 8 participants are lined up according to identities 1,2,3,4, 5,6,7,8
[2+2+2+2 +2+2+2+2] × 2 = 16×2 = 32

Answer:
yes
Step-by-step explanation:
Answer:
<u>The result is 3 1/2 and this is the explanation why Diego must convert 4 1/5 from mixed number to improper fraction.</u>
Step-by-step explanation:
These are the steps Diego should follow to find 4 1/5 - 7/10:
Step 1: Convert all mixed numbers into improper fractions.
4 1/5 = 21/5 - 7/10
Step 2: Find a common denominator between the improper fractions. When necessary, create equivalent fractions.
21/5 = 42/10 - 7/10
Step 3: Add or subtract the numerators and keep the denominator the same.
42 - 7 = 35/10
Step 4: If the answer is an improper form, reduce the fraction into a mixed number.
35/10 = 3 5/10 = 3 1/2
<u>The result is 3 1/2 and this is the explanation why Diego must convert 4 1/5 from mixed number to improper fraction.</u>
