Translate the word phrase into an algebraic equation: the quotient of 24 and 2 is equal to 12.
igor_vitrenko [27]

Answer:

24/2 = 12

Explanation:

(I'm pretty sure this isn't a Biology question, but I'll answer this because I'm nice.)

To translate English into algebriac equations, we have to understand what the symbols in algebra mean. Here are some we should know:

= : "equal to", "is", "equivalent to", etc.

> : "greater than"

< : "less than"

>= : "greater than or equal to", "at least"

<= : "less than or equal to", "at most"

We also have to know basic math operations:

a + b : "a added to b", "a plus b", "a combined with b", "a more than b", etc.

a - b : "a minus b", "b less than a", "b subtracted from a", etc.

a * b : "a multiplied by b", "a times b", "the product of a and b", etc.

a / b : "the quotient of a and b", "a divided by b", etc.

There are MUCH MORE examples of this, yet it becomes second-nature to change English sentences into algebra.

So, let's tackle the question. Sadly, it's pretty simple, so I won't really go in depth here. Since the quotient of a and b is a/b, the quotient of 24 and 2 is 24/2. We can also say that "is equal to 12" is "= 12". So,

24/2 = 12.

Arteries: any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.

Capillaries: any of the fine branching blood vessels that form a network between the arterioles and venules.

Veins: any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.

They are all similar because not only are they all connected to the heart, but they transfer blood and nutrients all around the body. They are different by where they are located and how effective their function is.

In a certain group of African people, 4% are born with sickle-cell disease, an autosomal recessive disorder. Heterozygous indivi
love history [14]

Answer:

the correct answer is C) 32%

Explanation:

Sickle-cell anaemia is an autosomal recessive genetic disorder. Individuals with the homozygous recessive have sickle-shaped blood cells. Whereas, individuals with heterozygous are only carrier of sickle cell trait. The carrier individuals are resistant to malarial parasite and do not have malaria.  

As per the question, 4% of an African population is born with sickle-cell disease, then the percentage of the population is heterozygous and resistant to malaria will be:  

Hardy-Weinberg formula is equilibrium,

        p² + 2pq + q² = 1  

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p2 = percentage of homozygous dominant individuals

q2 = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

Given, homozygous recessive for this gene (q2) is 4%  which is 0.04, the square root (q) is 0.2 (20%) then p should be 1-0.2 = 0.8 (20%).  

Thus, the frequency of heterozygous individuals = 2pq.  

2 (0.8 x 0.2) = 0.32 (32%).
