If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring

Answers

Answer:

50 percent

Step-by-step explanation:

It is given that one of the parent with a dominant trait have brown eyes and the other parent with a recessive trait has blue eyes. They produce a twin boy with eyes that is blue in color. So the probability of the fraternal twin to transmit his allele of blue eye to his or her offspring is 50 percent.

And also the probability of the offspring to pass the allele on to his or her offspring is 50 %.

The product rule is used : 0.5 x 0.5 = 0.25 or 25%.

Step-by-step explanation:

The two triangles are congruent because if each triangle's angles add up 180 degrees, you can deduce that the triangles have atleast two congruent angles.

Triangle RST:

48 + 73 = 121

180 - 121 = 59

Angle R = 59

Angle T = 48

Angle S = 73

59 + 48 + 73 = 180

Triangle ABC:

73 + 59 = 132

180 - 132 = 48

Angle A = 59

Angle B = 73

Angle C = 48

59 + 48 + 73 = 180

the correct answer would be A

Answers

Answer:

1, 3, 5 =117

2, 4, 6, 7= 63

Step-by-step explanation:

Since we know that one angle is 117 degrees, 5, 1 and 3 will also be 117. 2, 4, 6 and 7 will also be the same. 117 plus 117 is 234. 63 + 63 = 126. 234+ 126 = 360.

B.

C.

D.
62.3%

Answers

Answer: Your answer would be C) 32.1%

Step-by-step explanation:

With the number of successes needed to be 4 and the total amount of trials (games) for this to be achieved in being 6 you can calculate a percentage based on their currenting winning percentage of .623 (don't forget decimals can be percentages, just move the decimal point over) and you can input all of this into the binomial model equation to get your answer. Please do note also that it would be a different answer entirely if you were to use .500 (50%) as a winning percentage which would be the logical conclusion as any team has a 50/50 chance of winning a given game but instead the question is asking us to calculate this percentage off the already given winning percentage. After inputting the data into the model formula you can conclude the answer to be 32.1% chance of them winning 4 out of the next 6 games. I hope this has been of assistance to you :)

Which of these expressions equal 15 when x=1/2 and y=3? Circle all that apply. Please help with this my teacher need me to work out xy+3 1/2+20x Btw guys 3 1/2 are mixed numbers if your wondering

Answers

Answer:

15

Step-by-step explanation:

First you would replace the x and y's with 1/2 and 3.

So it would look like: (1/2) (3) + 3 1/2 + 20 (1/2)

Next, you go by PEMDAS (parenthesis, exponents, multiplications, division, addition, subtraction)

So you would first multiply and the parenthesis that I added mean multiplication.

1.5 + 3.5 + 10

So then all that is left to do is add because I multiplied everything out.

So it is 5 + 10 which is 15

If csctheta=11/4 & tan Thea< 0 Use the fundamental identities to evaluate cottheta.

Answers

Answer:

[tex]\cot{\theta} = -\frac{\sqrt{105}}{11}[/tex]

Step-by-step explanation:

Fundamental identities:

These following trigonometric identities are used to solve this question:

[tex]\sin^{2}{\theta}+\cos^{2}{\theta} = 1[/tex]

[tex]\csc{\theta} = \frac{1}{\sin{\theta}}[/tex]

[tex]\cot{\theta} = \frac{\cos{\theta}}{\sin{\theta}}[/tex]

With the cossecant, we can find the sine. So:

[tex]\csc{\theta} = \frac{1}{\sin{\theta}}[/tex]

[tex]\frac{11}{4} = \frac{1}{\sin{\theta}}[/tex]

[tex]11\sin{\theta} = 4[/tex]

[tex]\sin{\theta} = \frac{4}{11}[/tex]

With the sine, we find the cosine.

Since the tangent is negative, the cosine is negative. So

[tex]\sin^{2}{\theta}+\cos^{2}{\theta} = 1[/tex]

[tex](\frac{4}{11})^{2} + \cos^{2}{\theta} = 1[/tex]

[tex]\frac{16}{121} + \cos^{2}{\theta} = \frac{121}{121}[/tex]

[tex]\cos^{2}{\theta} = \frac{105}{121}[/tex]

[tex]\cos{\theta} = -\frac{\sqrt{105}}{11}[/tex]

Cotangent:

[tex]\cot{\theta} = \frac{\cos{\theta}}{\sin{\theta}}[/tex]

[tex]\cot{\theta} = \frac{-\frac{\sqrt{105}}{11}}{\frac{4}{11}}[/tex]

[tex]\cot{\theta} = -\frac{\sqrt{105}}{11}[/tex]

The function Y=4.75+2.20(X-1) can be used to determine the cost in dollars for a taxi ride in Houston, TX. What is the rate of change of the cost in dollars with respect to the number of miles?

Answers

Answer:

2.20 dollars/mile

Step-by-step explanation:

Given the function:

y = 4.75 + 2.20(x-1)

Before we get the rate of change of the cost, we need to write the expression in the form y = mx+c where;

m is the rate of change of the cost

From the function given:

y = 4.75 + 2.20(x-1)

Open the parenthesis

y = 4.75 + 2.20x -2.20

y = 2.20x + 2.55

On comparing with the standard

m = 2.20

Hence the rate of change of the cost in dollars with respect to the number of miles is 2.20 dollars/mile

Solve the following equation algebraically: 5x2 = 60

a. x~ +3 46
b. x~3.46
c. x = 12
d. X = +12​

Answers

Answer:

x = 3.46

Step-by-step explanation:

In this question, you have to solve the equation.

Solve:

5x² = 60

Divide both sides by 5.

x² = 12

In order to eliminate the exponent, you would square root both sides.

√x² = √12

x = √12

√12 = 3.4641..

x = 3.46

Your final answer would be x = 3.46

5. Si un paquete de 100 hojas iguales mide 1 cm de altura, ¿cuál


es el grosor de una hoja?

Answers

Responder:

0,01 cm

Explicación paso a paso:

Dado que :

Un paquete de 100 hojas iguales = 1cm de alto

Esto significa que el grosor del paquete es de 1 cm de alto.

Dado que las hojas son iguales, el grosor de una sola hoja será:

(Espesor del paquete completo / número de hojas en el paquete)

(1 cm / 100)

= 0,01 cm

Usando proporciones, se encuentra que el grosor de una hoja es de 0.01 cm.

Esto problema é solucionado por proporciones, se utilizando de una regla de três.

Hay 100 hojas iguales, al todo midiendo 1 cm de altura. ¿Cuál es la equivalente medida de 1 hoja?

La regla de três es dada por:

100 hojas - 1 cm

1 hoja - x cm

Aplicando multiplicación cruzada:
