Answer:
25.15 ponds is the weight of two year old baby corresponds to 10th percentile.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 29 pounds
Standard Deviation, σ = 3 pounds
We are given that the distribution of weight of two year old babies is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.10
P(X < x)
Calculation the value from standard normal z table, we have,

Thus, 25.15 ponds is the weight of two year old baby corresponds to 10th percentile.
Answer:
21%
Step-by-step explanation:
Actually there are three levels of process here.
If 100 calls are made only 70 calls are completed (since 30%not completed)
Out of these 70 completed we find that 40% i.e. 28 calls to a woman and 30% i.e. 21 go to a man.
28 females and 21 males
Out of 28 females 45% buy something =
Out of 21 males 40% buy something = 
Total percent of calls result in a sale = 
So 21% of calls result in a sale
This is the work shown with the answer. I hope this helps. God bless
