Define the term dominant traits?A trait is a distinguishing characteristic that a person possesses. Dominant traits are defined as having only one copy of a gene on a chromosome which expresses a specific trait.Individuals exhibit the dominant traits most prominently. Polydactyly is the dominant condition in this case.For the given condition,
The father has six fingers plus six toes, while the mother is still in normal condition. In this particular case, polydactyly is a dominant characteristic. Twelve percent of the couple's children are projected to have additional digits.Because the father has the dominant feature as well as the mother is now in normal condition, there is a 50% chance that this deformity will be passed down to children.
Thus, the likelihood of their next (third) child having additional digits is 1/2.

What is the chance of getting a heart in a deck of cards and a six on a dice both at the same time?
I need this really fast pls
Assuming it is a standard deck of 52 cards and a standard dice of 6 faces.
There are 13 heart cards in a standard deck, therefore the odd of getting a heart is 13 : 52 = 1/4.
There is only 1 six in a standard dice, therefore the odd of getting a six is 1/6.
For these events to happen simultaneously, we multiply the chances.
Therefore, the chance of getting a heart in a deck of cards and a six on a dice is 1/4 x 1/6 = 1/24.
Answer:
heart from a deck of cards= 13/52 = 1/4
getting a six on a dice= 1/6 = 1/6
Step-by-step explanation:
heart from a deck of cards :
In the context of ordinary maths questions the answer is so obvious as to almost not be worth mentioning. There are 52 cards in an ordinary deck and 13 of them have heart pips, so 13/52 = 1/4.
six from a dice :
There is a 1/6 chance of rolling a 6. There are only 6 sides on a die, and only 1 of them is 6, so there is a 1/6 chance of rolling a 6.
at the same time is:
13/15 + 1/6 = 31/30 = 1/30

The missing values in the ratio table include the following:
A = 2
B = 6
What is a proportional relationship?In Mathematics, a proportional relationship can be modeled or represented by the following mathematical expression:
y = kx
Where:
x represents the number of people.y represents the liters of ginger ale needed.k represents the constant of proportionality.In order for the ratio of the number of people to liters of ginger ale needed to have a proportional relationship, the variables x and y must have the same constant of proportionality.
Next, we would calculate the constant of proportionality (k) as follows:
Constant of proportionality (k) = y/x
Constant of proportionality (k) = 24/4
Constant of proportionality (k) = 6.
Now, we can determine the value of A and B:
A = x/k
A = 12/6
A = 2
For the value of B, we have:
B = x/k
B = 36/6
B = 6.

Find the Error When graphing the equation y=−3x+2, a student plotted the y-intercept at 2, then moved down 3 units and to the left 2 units because the slope is negative, so both rise and run are negative. Find his error and correct it.
Which selections describe an error that the student made and give the correct response? Select all that apply.
Multiple select question.
A)
The student used the y-intercept, 2, for the denominator of the slope. The slope should be −3 or −31 .
B)
The student said that, because the slope is negative, both rise and run are negative. When the slope is negative, either the numerator is negative or the denominator is negative, not both.

suppose goop purchases 150 gallons of raw material. what is the probability that they will run out of raw material?
The probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.
We have following information,
the demand for the polymer is distributed normally .
Mean (μ) = 250 gallons and Standard deviations (σ) = 125 gallons
Selling price of poymer = $25 per gallons
cost price of raw material for polymer= $ 10 per gallons
Salvage value = $(-5)/ gallon
Now, Using the formula for normally distributed sample,
Z = ( X - μ ) /σ
where , X---> sample mean
μ ----> population mean
σ----> standard deviations
Z -----> Z-value
from question it is clear X = 150
putting all the values of variables in above formula we get, Z = ( 150-250)/125 = -100/125
= - 0.8
(-0.8) value of z = 0.21 = 21% , the value of z is measure from normal distribution table.
They will run out of raw material if demands exceds this quantity or
Probability ( out of stock ) = 1 - 0.21 = 0.79 = 79%

A factory produces 270000 000 sweets every
week. How many sweets does the factory
produce in a year? Give your answer in
standard form
The factory produced 1.404 x 10⁶ sweets in a year
How to calculate the number of sweets the factory produce in a year?
Standard form is a way of writing very large numbers or very small numbers in a simpler form. It is also called scientific notation
Given that: The factory produces 270000000 sweets every
week.
To know how many sweets the factory produces in a year, we will multiply the quantity produced in a week by 52 since there are 52 weeks in a year. Thus:
Number of sweet in a year = Weekly production x 52
= 270000000 x 52 = 14040000000 sweets
To express 140400000000 in standard form, we will move the position of the decimal point to the back of the first number(1) and take note of the number of steps we take to get there. The number of steps will then be used as the power of 10:
14040000000 = 1.404 x 10⁶
Therefore, the number of sweets produced by the factory in a year in standard form is 1.404 x 10⁶ sweets

Answer:
y = 119
30 =x
Step-by-step explanation:
61 and y are same side interior angles and they add to 180
61+y = 180
y = 180-61
y = 119
y and 6x-61 are vertical angles and they are equal
y = 6x-61
119 = 6x-61
Add 61 to each side
119 + 61 = 6x
180 = 6x
Divide each side by 6
180/6 = x
30 =x
Answer:
y = 119°
x = 30°
Step-by-step explanation:
We know that if two lines are parallel, the co - interior angles are added up to 180°°.
Accordingly,
y + 61 = 180
y = 180 - 61
y = 119°
Also, we know that, vertically opposite angles are equal to each other.
y = 6x - 61
119 = 6x - 61
Now, we have to make x the subject.
For that, first, add 61 for both sides.
119 + 61 = 6x
180 = 6x
Now, divide both sides by 6.
30° = x
