Answer:

13 3/4

Step-by-step explanation:

So you have to think: 6 1/4 + ? =20

A way to find that out is 20 - 6 1/4

I like to split 6 1/4 into 6 and 1/4

First, you subtract 6 from 20

20 - 6 = 14

Then here is the tricky part:

14 - 1/4 = 13 4/4 - 1/4 = 13 3/4

Note: 13 4/4 is equal to 14 because 4/4 is equal to 1, so 13 + 1 = 14

Assuming you forgot the equal sign

y=|x|-6

test each
(x,y)
(-5,1)
1=|-5|-6
1=5-6
1=-1
fasle

(-1,-5)
-5=|-1|-6
-5=1-6
-5=-5
true

(5,-1)
-1=|5|-6
-1=5-6
-1=-1

the answer is
(-1,-5) and (5,-1)

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.
