Answer, please. Thanks in advance
myrzilka [38]

Answer:

y = -2/4x + 2 --- SLOPE INTERCEPT FORM

OR IF WANTING IT TO BE SIMPLIFIED:

y = -1/2x + 2 --- SLOPE INTERCEPT FORM

Step-by-step explanation:

The starting point is 2. The slope is -2/4 or if it needs to be simplified, then it's -1/2.


Sorry if I'm incorrect...

Lostsunrise [7]
Convert 8 hours and 15 minutes into minutes-   8 x 60=480 480+15=495
100%-75%=25%
25%=0.25
0.25 x 495  = 123.75 minutes or 2 hour and 3.75 minutes

Hope this helps!!

Assume that long earlobes in humans are an autosomal dominant trait that exhibits 30% penetrance. A person who is heterozygous f
Bess [88]

Answer:

0.75

Step-by-step explanation:

Autosomal dominant: A pattern of inheritance in which an affected individual has one copy of a mutant gene and one normal gene on a pair of autosomal chromosomes

Heterozygous just means that a person has two different versions of the gene (one inherited from one parent, and the other from the other parent).

Being homozygous for a particular gene means you inherited two identical versions.

The trait is autosomal dominant so the characters pass into the next generation in a large ratio. the person who is heterozygous for the character have two type of allele which represents the trait for long earlobes and also for short earlobe.So a person is paired with homozygous individuals who have pure character for short earlobes.The percentage of their first child with long earlobes would be 75 percent. This is due to the dominance of the character in a generation.

The perimeter of the isosceles ?ABC with the base BC is equal to 40 cm. Perimeter of the equilateral ?BCD is 45 cm. Find AB and
Juliette [100K]

Answer: AB = 12.5, BC = 15

<u>Step-by-step explanation:</u>

Perimeter of ΔBCD = BC + CD + BD. Since it is an isoceles triangle, then BC = CD = BD. So, Perimeter of ΔBCD = 3BC

3BC = 45

<u>÷3   </u>    <u>÷3 </u>

 BC = 15

Perimeter of ΔABC = AB + BC + AC.  Since it is an isosceles triangle with BC as the base, then AB = AC. So, Perimeter of ΔABC = 2AB + BC

2AB + BC = 40

2AB + 15 = 40

<u>          -15</u>  <u> -15 </u>

2AB       = 25

<u>÷2         </u>   <u>÷2  </u>

      AB  = 12.5
