Insert three arithmetic means between 25 and 9

Aleonysh [2.5K]

Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = $\frac{25+9}{2}$ = $\frac{34}{2}$ = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = $\frac{25+17}{2}$ = $\frac{42}{2}$ = 21 and

mean = $\frac{17+9}{2}$ = $\frac{26}{2}$ = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9

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.
