How to turn a fraction into a decimal, help

1 answer:

6 0

A fraction is really just another way to write a division problem without dividing. So all you have to do is divide, then round to whichever decimal place your teacher wants.

Human blood is generally classified in the "ABO" system, with four blood types: A, B, O, and AB. These four types reflect six ge

Nikitich [7]

Answer: The probability for A is p², for B is q² and for O is r².

The probability for two different genes is, in this case, 2pq+2qr+2pr.

The maximum percentage is 2/3.

Step-by-step explanation: According to the Hardy-weinberg principle states, in a population where there's no external factors changing the proportion of genes, the probability of frequencies would be calculate as (p+q+r)*(p+q+r)=1.

Calculating :

(p+q+r)²= p²+2pq+2pr+2qr+q²+r²

As p represents the frequency of genotype AA, the probability is P(A)=p²; as if for genotype BB is P(B)=q² and genotype OO is P(O)=r².

For the probability of two different genes, the answer is P(A,B,O)=2pq+2qr+2pr, since these represents the "mixture" of the genes.

The maximum percentage calculated by using Lagrange multipliers is demonstrated below:

F(p,q,r)= 2pq+2pr+2qr-λ(p,q,r)

Note: λ(p,q,r) are the Lagrange multipliers and F(p,q,r) is the function which relates the three frequencies.

We use partial derivatives:

Fp= 2q + 2r - λ

Fq=2p + 2r - λ

Fr=2p + 2q -λ

p + q + r = 1

Solving by λ and dividing by 2, we have

q + r = p + r = p + q

Using p+q+r=1 and substituting <u><em>p</em></u> by

p= 1 - q - r

we have q + r = 1 - q = 1 - r

From the first equation, we have r= 1 - 2q

Substituting into the 2nd equation, we have

1 - q = 1 - (1-q) =2q so q = 1/3

Resolving for the others, we have p=1/3 and r=1/3.

Calculating probability:

P(A,B,O)=2(1/3)(1/3)+2(1/3)(1/3)+2(1/3)(1/3)

P(A,B,O)=2/3

The Lagrange multipliers represents the external factors, for example mutations or migrations, capable of changing the frequency of the genes.

a line in the coordinate plane has an angle of elevation of 53 degrees. Find the slope of the line correct to four decimal place

Sergeu [11.5K]

Let's make a reference triangle with the x and y axes as the legs of the right triangle. The hypotenuse is the slope where the angle of elevation is based. Given an angle of elevation of 53 degrees, the remaining angle is 37 degrees. Use sine law to calculate for the hypotenuse:

(sin 53/x) = (sin 37/y) = (sin 90/z)

solve for x, y and z. The slope is y/x

GarryVolchara [31]

The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.

Step-by-step explanation:

The given is,

The volume of soup to be 325 cubic centimeters per can.

The area of the base of each can is 25 square centimeters.

Step: 1

Formula to calculate the volume of cylidrical soup can,

$Volume, V = Bh$ ............................(1)

Where, B - Base area of cylidrical soup can

h - Height of cylindrical soup can

Step: 2

From the given values,

Base area, B = 25 square centimeters

Volume, V = 325 cubic centimeters

Equation (1) becomes,

325 = ( 25 ) (h)

h = $\frac{325}{25}$

= 13 centimeters

Height of cylindrical soup can, h = 13 centimeters

Result:

The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.
