In a population of 1000 snails, tests of snail color genes show that 160 snails are AA, 480 are Aa and 360 are aa. What is the f

Kipish [7]

Answer:

Option C.

Step-by-step explanation:

Total population = 1000 snails

AA = 160 snails

Aa = 480 snails

aa = 360 snails

Frequency of each type.

$AA=\dfrac{160}{1000}=0.16$

$Aa=\dfrac{480}{1000}=0.48$

$aa=\dfrac{360}{1000}=0.36$

Now, we get

$A^2=0.16\Rightarrow A=\sqrt{0.16}=0.4$

he frequency of the A allele in this population is 0.4.

Therefore, the correct option is C.

Factor-3/4 out of 3/2x-9/4y

S_A_V [24]

For this case we must factor $- \frac {3} {4}$ of the following expression:

$\frac {3} {2} x- \frac {9} {4}y$

By law of signs of multiplication it is fulfilled that:

$- * - = +\\- * + = -$

So we have to:

$- \frac {3} {4} * (- 2) = + \frac {6} {4} = + \frac {3} {2}\\- \frac {3} {4} * 3 = - \frac {9} {4}$

Thus, by factoring we have:

$- \frac {3} {4} (- 2x + 3y)$

Answer:

$- \frac {3} {4} (- 2x + 3y)$

What is 60 + 50.45x = 57.95x and how do I know which part of the equation to solve at which time?

Aleksandr-060686 [28]

Answer:

$x=8$

Step-by-step explanation:

First, subtract 50.45x from both sides. Then divide by 7.5 on both sides.

$60+50.45x=57.95x\\60=7.5x\\x=8$
