Answer:
40
Step-by-step explanation:
the awnser is 40
2x + 2 > 10
2x + 2 - 2 > 10 - 2
2x > 8
2x / 2 > 8 / 2
X > 4
Step-by-step explanation:
I would suggest that this is cluster sampling.
The teacher is selecting a cluster of the population at random to sample.
This is a method of probabalistic sampling.
Answer:
The question is incomplete, this is the complete question.;
There are five nickels, five dimes and five quarters in your pocket. You randomly pick three coins and place them on the counter the first coin is a nickel, the second is a dime and the third is a quarter.find the probability of this occurring.
The answer to the question is;
the probability of this occurring is 1/27
Step-by-step explanation:
Let n(N) =5 ( the number of nickels)
n(D) =5 ( the number of dimes) and
n(Q) = 5 ( the number of quarters)
P(N)= 5/15=1/3 (prob of picking a nickel)
P(D) =5/15=1/3 (prob of picking a dime)
P(Q) = 5/15= 1/3 (prob of picking a quatre)
The probability of picking the three= P(N)×P(D)×P(Q)
= 1/3×1/3×1/3
= 1/27
1 kilometer= 1000 meters
3x1000= 3000 meters
3000/ 25= 120 pool lengths
