Answer: b. finding all studies published on a topic, calculating the effect size for each of those studies, and averaging the effect sizes together to find the average size of the effect across all studies.
Step-by-step explanation:
Y=x2 the extreme would be x=0
The probability is P = 0.004, so the correct option is D.
<h3 /><h3>How to find the probability?</h3>
We want to find the probability that 4 students lie on these 30% subgroup.
We know that there are 30 students, the 30% of 30 is:
x = (30%/100%)*30 = 9
So 9 out of 30 students prefer the tests to be on Mondays.
The probability that the first randomly selected kid wants the test to be on Monday is:
p= 9/30
For the next kid, the probability is:
p'= 8/29 (because one kid was already selected).
For the next one:
p'' =7/28
For the final one:
p''' =6/27
The joint probability is the product of these 4:
P = (9/30)*(8/29)*(7/28)*(6/27) = 0.004
So the correct option is D.

1. the factors of 24 are 1, 24, 2, 12, 3, 8, 4, and 6. Each pair, fx. 1 and 24 with be 24 when multiplied.
2. Quaderant 3, quaderants go from 1 to 4 counterclockwise, and a (negative x, negative y ), will be in the 3rd quaderant if you go counterclockwise.
3. 7×x, the answer is simple 7 and x, with the key words "product of" which signify multiplication so it will be 7 times x.
