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.
1/2 would not be a useful benchmark to compare these 2 fractions because both of them are greater than half. The benchmark fraction 1/2 is most useful when one fraction is less than half and the other more than 1/2. 5/8 is more than 4/8(1/2), and 9/10 is more than 5/10(1/2).

Answer: 239
Step-by-step explanation:
Your mistake is that 1 pound and 15 ounces <em>does not equal</em> 1.15 pounds. You also did not make everything into the same measurement (you mixed up pounds and ounces). I will make everything into the measurement of <em>ounces</em>, since the numbers do not come out clean if we do pounds.
18 pounds (original) = 288
1 pound 15 ounces = 31 ounces
3 1/8 pound = 50 ounces
4 1/2 pound = 72 ounces
So after cutting out those steaks, Mr. Rand has 288-31-50-72 = 135 ounces. Then, it states that he divides those up into 9 ounce patties:
135/9 = 15 patties
And sells them at 3 for $3.12. There are 5 3's in 15 patties, so it is 5 * $3.12 = Mr Rand receives $15.60 for the patties.
