Answer:
(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:9 7/8
Step-by-step explanation:
You combine the whole numbers which are 6 and 3 the sum of that is 9 and then to add fractions you make the denominators the same so you do 2x3/4 =6/8 +1/8=7/8
Answer: y = 64
Step-by-step explanation:
y <> x² ----------------------- 1
y = kx² ----------------------- 2
36 = 3²k
36 = 9k
K = 36/9
= 4.
To find y when x = 4, we substitute for x in equation 2
y = kx²
y = 4²k
y = 16 x 4
y = 64
okay, so.
it's a rectangle with a nub. We do the area without the nub first. so 8x16 is 128
now, its time for the nub.
6x12-8, that would be 4, so 6x4 is 24+128= 152
So it's B.
Hope i helped Mark brainliest pls
