Volume of the base = base area x height
512 = 3√3 / 2 a²h
h = 197/a², where a is the length of the side of the hexagonal base.
Answer: Parents.
Step-by-step explanation:
- In statistics , a population is a large group of similar things or members by researcher's perspective from that he/ she draw a finite subset also known as sample to follow his / her research.
Here, Sharon wants to estimate the percentage of parents that use cloth diapers.
i.e.Researcher = Sharon
Since Sharon will reach parents about her objective of whether they use cloth diapers.
So , Population = Parents
If She asks a randomly selected group of 75 parents whether or not they use cloth diapers , then Sample size is 75 .
Therefore, the population is : "Parents."
To calculate this, the Hardy-Weinberg principle can be used:
p² + 2pq + q² = 1 and p + q = 1
where p and q are the frequencies of the alleles (p - dominant, q - recessive), and p², q² and 2pq are the frequencies of the genotypes.
a) Since 32 plants have rough seed (recessive genotype: q²) out of 100 plants in total, then
q² = 32/100 = 0.32
b) q = √q² = √0.32 = 0.56
c) Since p + q = 1, then
p = 1 - q = 1 - 0.56 = 0.44
d) 19 plants with rough seeds (recessive genotype: q²) in a population of 100 means that q² = 19/100 = 0.19
We need to calculate p (the allele frequency for smooth seeds).
We can find q because we know q²:
q = √q² = √0.19 = 0.44
Since p + q = 1, then
p = 1 - q = 1 - 0.4 = 0.56
Answer:
It depends on the cost of grapes.
Step-by-step explanation:
Half of 12 is 6, so if each pack of grapes cost 6 or less, she can buy a pack of green and red grapes.
