Answer:

x=14

Step-by-step explanation:

The angles are opposite each other, which means they are vertical angles. Therefore, the two angles are equal to each other. We can set them equal to each other.

43=3x+1

Solve for x,by getting x by itself. First, move all the numbers to one side. To do this, subtract 1 from both sides

43-1=3x+1-1

42=3x

x is still not by itself, it is being multiplied by 3. To undo this, divide both sides by 3

42/3-3x/3

14=x

It is given that the sample size is 17.

So degrees of freedom is 16.

The confidence level is 80%.

Use the t table or a tool to find the critical t value as below:

The one tail t value for 80 percent confidence is 0.865 using t table.

So the critical value is 0.865.

"Suppose that allele D produces long toes and allele d produces normal toes. A heterozygous male with the Dd genotype mates with

VARVARA [1.3K]

Answer:

30%

Step-by-step explanation:

The crossing of a male with genotype Dd with a female with genotype dd, yields the following possible outcomes:

Dd, dD, dd, dd.

Therefore, there is a 2 in 4, (50%) chance that their offspring will have the dominant allele. Since its penetrance is 60%, the dominant trait will only manifest itself in 60% of heterozygous individuals. Therefore, the probability that their offspring will have long toes is:

$P = 0.50*0.60\\P=30\%$
