Answer: The answer is 
Step-by-step explanation: Given that Lee and Maya are collecting leaves for an art project. Let'x' be the total number of leaves needed in the project.
Then, the number of leaves collected by Lee is given by

and the fraction of the leaves collected by Maya is given by

Therefore, the total number of leaves collected by Lee and Maya altogether is

Thus, the total fraction of the leaves collected by Lee and Maya is

840? Im not sure im sorry
12 1/2 = 12.5
2.5mm = 2.5 cm
So the answer would be 15 cm
Answer:
Probabilty of not poor= 0.75
Step-by-step explanation:
total of 11332 bonds.
7311 are good risk.
1182 are medium risk.
Poor risk
= total risk-(good risk+ medium risk)
= 11332-(7311+1182)
= 11332-8493
= 2839.
Poor risk = 2839
Probabilty that the ball choosen at random is not poor= 1 - probability that the ball is poor
Probability of poor = 2839/11332
Probabilty of poor= 0.2505
Probabilty that the ball choosen at random is not poor= 1- 0.2505
= 0.7495
To two decimal place= 0.75
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.
