In a population of mendel's garden peas, the frequency of dominant yellow-flowered plants is 50%. The population is in hardy-weinberg equilibrium. What is the frequency of the recessive allele in the population?.
Answer:
the frequency of the recessive allele in the population is 0.5 or 50%.
Step-by-step explanation:
In a population in Hardy-Weinberg equilibrium, the frequency of alleles remains constant from generation to generation. According to the Hardy-Weinberg law, if p is the frequency of the dominant allele and q is the frequency of the recessive allele, then:
p + q = 1
and
p^2 + 2pq + q^2 = 1
where p^2 represents the frequency of homozygous dominant individuals, 2pq represents the frequency of heterozygous individuals, and q^2 represents the frequency of homozygous recessive individuals.
Given that the frequency of dominant yellow-flowered plants is 50%, or 0.5, we can assume that p = 0.5. Substituting into the first equation, we get:
0.5 + q = 1
Solving for q, we get:
q = 1 - 0.5
q = 0.5
Therefore, the frequency of the recessive allele in the population is 0.5 or 50%.

The measures of the angles obtained using circle theorems are presented as follows;
a = 90°, b = 12°, c = 64°, d = 54°, e = 54°, f = 48°, g = 66°, h = 32°, i = 36°, and j = 20°
What are circle theorems?Circle theorems are theorems that indicates the relationships between angles, sector, chords, and tangent in a circle.
Please find the possible drawing in the question created with MS Word
a + a = 2·a = 180° (Linear pair angles)
a = 180°/2 = 90°
a = 90°
The right triangle with the acute angle angle of 78° indicates;
b = 90° - 78° = 12°
b = 12°
The angle at the center theorem indicates that we get;
The base angle of the large isosceles triangle = 2 × 32° = 64°
∠c is a base angle of the large triangle, therefore;
c = 64°
2·c + d = 180°
d = 180° - 2 × 48° = 54°
e = d = 54°
e = 54°
The angle at the circumference of the circle with angle ∠g and and ∠f = 4·b
Angle at the circumference = 4 × 12° = 48° = ∠f
f = 48°
Angle ∠g is equivalent to a base angle of the isosceles triangle, therefore;
∠g = (180° - 48°)/2 = 66°
g = 66°
Angle at the vertex of the triangle with angle h is equivalent to the base angle of the large triangle, therefore;
2·h = 64°
h = 64°/2 = 32°
h = 32°
Angle at the center = 2 × (180° - 2 × 48°) = 168°
5b + 2f + i + 168° = 360° (Angle sum property of a quadrilateral)
i = 360° - (5b + 2f + i + 168)
i = (360 - (5×12 + 2×48 + 168) = 36
i = 36
5b + 2h + i + j = 180
j = 180 - (5b + 2h + i)
j = 180 - (5 × 12 + 2 × 32 + 36) = 20°
j = 20°

tommmy earns $140 in interest after 5 years on a pricipal of $400 jane earned $132 after 4 years on principal of $600 use the intrest rate to justify which bank would you rather use tommys or janes
Comparing the interest rates of Jane and Tommy, we can say that Tommy's bank is better because he earns more amount of money for less principal amount.
What is meant by the interest rate?The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.
The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.
Given,
Interest earned by Tommy SI = $140
Time t = 5 years
Principal amount P = $400
Interest earned by Jane SI = $132
Time t = 4 years
Principal amount P = $600
Simple interest SI = (P × r × t)/100
where r = interest rate
For Tommy,
140 = ( 400 × r × 5) /100
r = 7%
For Jane,
132 = ( 600 × r × 4) / 100
r = 5.5%
Therefore comparing the interest rates of Jane and Tommy, we can say that Tommy's bank is better because he earns more amount of money for the less principal amount.

Cera and Bethany save money using savings accounts
opened on the same day. Both deposit $20 to start and an
additional $15 each week. The graph represents the total
amount, y, in each savings account after x weeks. Describe
the number of solutions modeled in the graph and what it
means for the situation. How can you change the situation
so that the graphs model a different number of solutions?
Explain your reasoning
This could result in one, two, or multiple points of intersection, depending on the specific values of the deposits and the rates of increase.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
we can assume that the graph of Cera's and Bethany's savings accounts will show the total amount of money in their accounts after a certain number of weeks.
Since both Cera and Bethany deposit the same amount of money and make the same additional deposits each week, their savings will increase at the same rate. Therefore, the graph will likely show two parallel lines that start at $20 and increase by $15 per week.
The number of solutions modeled by the graph will depend on whether the two lines ever intersect. If the lines do not intersect, then there is no solution to the system of equations that model the two savings accounts. In other words, there is no point at which the total amount of money in both accounts is the same.
On the other hand, if the lines do intersect, then there is at least one solution to the system of equations. In this case, the point of intersection represents the week at which the total amount of money in both accounts is the same.
To change the situation so that the graphs model a different number of solutions, we could change the initial deposit or the amount of money deposited each week for one or both of the savings accounts. For example, if Cera starts with a higher initial deposit than Bethany, or if Cera deposits more money each week, then their savings will increase at different rates and the lines on the graph will not be parallel.
Therefore, This could result in one, two, or multiple points of intersection, depending on the specific values of the deposits and the rates of increase.

A field is in the shape of a square. The length of the field is 5x³y5. What is
the area of the field terms of x and y?
Answer: The area of a square is given by the formula A = s^2, where s is the length of a side of the square.
In this case, the length of the field is 5x³y5, so each side of the square is also 5x³y5. Therefore, the area of the square can be found as:
A = (5x³y5)^2
A = 25x^6y^10
So the area of the field in terms of x and y is 25x^6y^10.

Elsa menabung uang di bank sebesar Rp.2.000.000,00. Apabila ia mendapat bunga 0,5% perbulan, berapa jumlah uang tabungan di bank selama 10 bulan?
Answer:
Jumlah uang tabungan Elsa setiap bulan dapat dihitung dengan rumus:
A = P(1 + r)^n
dimana:
A = jumlah uang tabungan akhir
P = jumlah uang tabungan awal
r = tingkat bunga per bulan (dalam desimal)
n = jumlah bulan
Dalam kasus ini, P = Rp.2.000.000,00, r = 0,5% atau 0,005 per bulan, dan n = 10 bulan.
Maka,
A = 2.000.000(1 + 0,005)^10
= 2.000.000(1,005)^10
= 2.000.000(1,0512)
= Rp.2.102.400,00

What is congruence?Generally, To prove that triangle ABE is congruent to triangle CDE, we need to show that they have the same size and shape.
First, we can see that angle AED and angle CEB are opposite angles and therefore congruent, since AB || DC.
Also, since line AB = line DC, we know that segment AE is congruent to segment CE and segment BE is congruent to segment DE.
Using these congruent sides and the congruent angle, we can apply the Side-Angle-Side (SAS) congruence criterion to conclude that triangle ABE is congruent to triangle CDE.

Suppose that a company wishes to predict sales volume based on the amount of advertising expenditures. The sales manager thinks that sales volume and advertising expenditures are modeled according to the following linear equation. Both sales volume and advertising expenditures are in thousands of dollars.
Estimated Sales Volume=45.15+0.54(Advertising Expenditures)
If the company has a target sales volume of $125,000
, how much should the sales manager allocate for advertising in the budget? Round your answer to the nearest dollar.
Answer:
We can use the given equation to solve for the advertising expenditures needed to achieve the target sales volume of $125,000:
125 = 45.15 + 0.54x
where x is the advertising expenditures in thousands of dollars.
Simplifying the equation:
0.54x = 125 - 45.15
0.54x = 79.85
x = 79.85 / 0.54
x ≈ 147.69
Therefore, the sales manager should allocate about $147,690 for advertising in the budget to achieve the target sales volume of $125,000.

1. The Range of Elevation for Long beach is 367 feet.
2. The Range of Elevation for New Orleans is 33 feet.
3. New Orleans have the average of 2 feet below sea.
What is Range?In statistics, the range is the difference between the highest and lowest values for a given data collection.
Given:
1. The Range of Elevation for Long beach
= Highest - Lowest
= 360 - (-7)
= 360 + 7
= 367 feet
2. The Range of Elevation for New Orleans
= Highest - Lowest
= 25- (-8)
= 25+ 8
= 33 feet
3. New Orleans have the average of 2 feet below sea.

O False
Answer:true
Step-by-step explanation:
Which step is incorrect?
Answer:
c step 3
Step-by-step explanation:
from the correct x^(2/5) do we suddenly get to
x^(5/2).
1/x³ = x^(-3) is a correct identity, and using it has no impact on x^(2/5). that should still stay x^(2/5).
the correct step 3 is then
x^(2/5)x^(-3)
step 4 is then
x^(2/5 - 3) = x^(2/5 - 15/5) = x^(-13)/5
A spice box manufacturing company is having difficulty filling packets to the required 50 grams. Suppose a business researcher randomly selects 60 boxes, weighs each of them and computes its mean. By chance, the researcher selects packets that have been filled adequately and that is how he gets the mean weight of 50 g, which falls in the "fail to reject" region.
The decision is to fail to reject the null hypothesis even though population mean is NOT actually 50 g.
Which kind of error has the researcher done in this case?
Answer: The researcher has made a Type II error in this case.
A Type II error occurs when the null hypothesis is not rejected even though it is false, i.e., the researcher fails to detect a significant difference when one actually exists. In this case, the null hypothesis is that the mean weight of the spice packets is 50 g, and the researcher has failed to reject this null hypothesis based on the sample mean of 50 g.
However, the population mean is not actually 50 g, and the researcher has made an error in failing to detect this difference. The sample size of 60 boxes may not have been large enough to detect a significant difference, or there may have been other factors that affected the measurements.
Therefore, the researcher has made a Type II error in this case by failing to reject the null hypothesis when it is actually false.
