f(x) = \dfrac{4x - 3}{7}

y = \dfrac{4x - 3}{7}

x = \dfrac{4y - 3}{7}

7x = 4y - 3

7x + 3 = 4y

4y = 7x + 3

y = \dfrac{7x + 3}{4}

f^{-1}(x) = \dfrac{7x + 3}{4}

In a population that is in Hardy-Weinberg equilibrium for two alleles, D and d. D shows complete dominance over d (i.e. heterozy
slavikrds [6]

Answer:

0.28

Step-by-step explanation:

Hardy-Weinberg equilibrium states that the frequency of allele and genotype will remain the same from generation to generation in the the absence of evolutionary influences. Such evolutionary disturbance include:  mutation, non-random mating,  gene flow, natural selection, genetic drift and others ,  

His equilibrium is denoted by the equation;

p² + 2pq + q² = 1

p² + 2pq represent the dominant phenotype which comprises of f (DD) = p² and f (Dd) = 2pq and is equal to 0.72

then the f(dd) =q² = 1 - 0.72 = 0.28

Br uh don’t even type “I can’t see the pic” Solve both problems and show ur work
Aloiza [94]

Answer:

1.22

53.08

Step-by-step explanation:

4. We can find the quarter circle, we can find the whole triangle, lets do that

The circle is, 1/4*(1)^2*pi, which is 1/4pi

The triangle is, 2 * 2 divided by 2, which is 2

2 - 1/4pi gives us the shaded part or

2 - 1/4*3.14

2 - 0.785 = 1.215 rounded to 1.22

5. The area of a cylinder is pir^2h. r is 10, h is 1.2

12pi cm^3

we have 20 m^3 which is 2000 cm^3

Let's divide,

2000/37.68 = 53.078, rounded gives us 53.08
