Answer:
Step-by-step explanation:
Your total is 4 and each one is a individual (1)
so the probability of 1 ball would be :
because the question asks for the probability they are picked 4 times, we would need to multiply ¼ four times.
Answer:
1/12.
Step-by-step explanation:
The numbers divisible by 6 are 6, 12, 18, 24, 30 and 36.
Of these 12, 24 and 36 are also divisible by 4.
So the required probability is 3/36
= 1/12.
Answer:
5x - 1 = 3(x + 11)- Has one solution
4(x-2) + 4x = 8(x -9) 0- Has one solution
4(x - 6) + 4 = 2(x - 3)- Has one solution
2(x - 4) = 5(x - 3) + 3- Has one solution
2(x - 1) + 3.x = 5(x - 2) + 3- Has no solution
Answer:
C
Step-by-step explanation:
A. is wrong because having a different height for each seedling and not trying to keep it equal is simply worse than making sure the heights are identical.
B. Completely wrong because it would likely result in 1 plot having more melon seedlings than the other.
C. Correct because it makes sure the seedlings are the same height at the beginning of the experiment, allowing less randomness in the experiment.
D. Putting the taller of a each pair for 1 plot makes it the experiment rigged in favor of the plot with taller seedlings
E. Same issue as D.
It depends what company your using and the size of the van (:
