Answer: The probability of finding a white individual among the progeny if you cross these two animals is ¼.
Step-by-step explanation: Since these two animals are heterozygous black animals (Bb), crossing Bb x Bb will produce offsprings that are black (¾) and white (¼).
The first B will meet with the second B to form a BB (Black) progeny.
The first B will meet with the second b to form Bb (Black) progeny.
Likewise, the first b will meet with the first B to form Bb (Black) progeny.
Lastly, the first b will meet with the second b to form bb (white) progeny.
These are the possible progeny from the cross between Bb and Bb. Therefore, the probability of having white offspring is ¼.
Answer:
9/20
Step-by-step explanation:
Find the common denominator:
1/5 and 1/4
1/5*4/4 = 4/20 and 1/4*5/5 = 5/20
So we can add them together now
4/20 + 5/20 = 9/20
so 9/20 of her customers order fish or chicken

Answer:
Twelve dollars per hour
Step-by-step explanation:
Add 2 1/2 and 4 1/4 together to get 6 3/4. Put it into decimal form (6.75), and divide. 81 ÷ 6.75 = 12.
1 ) the formula used to calculate the simple interest is
I = Ci*n, f his formula you obtain n , that is the time in years n = I/ Ci, where c is the initial capital, i is the earned interest , and i is he rate of interest,
n = 120/600 (0,025) = 120 / 15 = 8 , at 8 years, you will obtain $ 120 of INTEREST
