Assume that genes A and B are not linked. If the probability of allele A in a gamete is 1/2 and the probability of allele B in a
kondor19780726 [428]

Answer:

P(A and B) = 1/4

Step-by-step explanation:

Since A and B are not linked. The event is said to be independent events:

Therefore;

P(A and B) = P(A) × P(B)

Where; P(A and B) is the probability that both A and B are in the same gamete.

P(A) = 1/2 => Probability of allele A in the gamete

P(B) = 1/2 => Probability of allele B in the gamete

Thus,

P(A and B) = P(A) × P(B) = (1/2) * (1/2) = 1/4 = 0.25.

Sydney placed 10 guppies in a fish tank she recorded the number of guppies in the tank
pav-90 [236]

Answer:

g(n) = 10 * 3^{n}

Step-by-step explanation:

Given

See attachment for table

Required

Determine the explicit formula for the table

First, we need to check if the guppies increases at arithmetic progression or geometry progression.

For arithmetic progression:

We calculate the common difference (d)

d = g(n) - g(n-1)

Take n as 1

d = g(1) - g(1-1)

d = g(1) - g(0)

From the table:

g(1) = 30\ \&\ g(0) = 10

d = 30 - 10

d = 20

Take n as 2

d = g(2) - g(1)

From the table:

g(1) = 30\ \&\ g(2) = 90

d = 90 - 30

d = 60

The two differences are not equal. So, this

For geometry progression:

We calculate the common ratio (r)

r = \frac{g(n)}{g(n-1)}

Take n as 1

r = \frac{g(1)}{g(1-1)}

r = \frac{g(1)}{g(0)}

From the table:

g(1) = 30\ \&\ g(0) = 10

r = \frac{30}{10}

r = 3

Take n as 2

r = \frac{g(2)}{g(1)}

From the table:

g(1) = 30\ \&\ g(2) = 90

r = \frac{90}{30}

r = 3

The two ratios are equal.

So, the next step is to calculate the explicit formula using n term of a geometric progression.

Because the progression starts from 0, we make use of the following formula

g(n) = g(0) * r^{n}

Substitute values for g(0) and r

g(n) = 10 * 3^{n}

Hence:

The explicit formula is: g(n) = 10 * 3^{n}

Somebody please help me with my geometry
RSB [31]

Answer:

AB + BC = AC

BC = AC - AB

5x + 6 = 37 - (2 x + 3) = 37 -2 x - 3 = 34 - 2 x

7 x = 34 - 6 = 28

x = 4

BC = 5 x + 6 = 5 * 4 + 6 = 26

Check:

AB = 2 x + 3 = 2 * 4 + 3 = 11

AB + BC = 26 + 11 = 37

Factor 3x^2-19x+20 ​
dusya [7]

Answer:

(3x-4)(x-5)

Step-by-step explanation:

This is in the form

ax²+bx+c.

To factor this, we find factors of a·c that sum to b; this means factors of 3(20) = 60 that sum to -19:

60 = 1(60) or -1(-60); 2(30) or -2(-30); 3(20) or -3(-20); 4(15) or -4(-15); 5(12) or -5(-12); 6(10) or -6(-10).  The only of these that sum to -19 are -4 and -15.  This means we will split up -19x into -4x and -15x:

3x²-4x-15x+20

Next we group the first two terms and the last two terms:

(3x²-4x)+(-15x+20)

Factor out the GCF of each group.  For the first group, this is x:

x(3x-4)

For the second group, this is -5:

-5(3x-4)

The common factor for these two groups is (3x-4):

(3x-4)(x-5)
