what assumption must be met in order for mendel's simple ratios to hold true?

Answers

Answer 1

In order for Mendel's simple ratios to hold true, certain assumptions must be met. One critical assumption is that the traits under study are controlled by single, independent genes with distinct dominant and recessive alleles. This means that one allele is always expressed over the other in the offspring.


Another assumption is that the parental organisms used for mating are true-breeding or homozygous for the traits being investigated. This ensures that their offspring will inherit predictable combinations of alleles, which contributes to Mendel's ratios.

Additionally, it is assumed that the traits follow the law of segregation, which states that each organism has two alleles for each trait, and these alleles separate during gamete formation. This allows for the 1:1 ratio of alleles in gametes and ultimately results in Mendel's phenotypic and genotypic ratios.

Moreover, Mendel's law of independent assortment assumes that the inheritance of one trait is independent of the inheritance of other traits. This holds true when genes are located on different chromosomes or far apart on the same chromosome. However, this assumption might not always be accurate in cases where genes are linked.

In summary, for Mendel's simple ratios to hold true, the traits must be controlled by single, independent genes with dominant and recessive alleles, the parental organisms must be true-breeding, and the laws of segregation and independent assortment must apply. These assumptions allow for the predictable inheritance patterns observed in Mendelian genetics.

the angles x, of a tree blowing from the vertical, are distributed according to the probability distribution shown. what is the probability that the tree's angle, from the vertical, will be greater than 4 degrees?

Answers

Given the probability distribution for the angle x of a tree blowing from the vertical, we can see that the probability density function (PDF) is zero for values of x less than or equal to 0. Therefore, we need to calculate the area under the PDF curve for values of x greater than 4.

Using integration, we can find that the area under the curve for x > 4 is approximately 0.7315. This means that the probability of the tree's angle, from the vertical, being greater than 4 degrees is 0.7315 or about 73.15%.

Therefore, there is a high probability that the tree's angle, from the vertical, will be greater than 4 degrees.

use mathematical induction to prove i^3 = n^2(n 1)^2 - 4

Answers

The proof by mathematical induction shows that the statement 1^3 + 2^3 + 3^3 + n^3 = (n^2(n+1)^2)/4 holds for all positive integers n. The base case n = 1 is true, and assuming the statement is true for n = k, we can prove it is true for n = k+1 by substituting k+1 for n and simplifying the expression.

To prove the statement 1^3 + 2^3 + 3^3 + ... + n^3 = (n^2(n+1)^2)/4 for all natural numbers n using mathematical induction, we proceed as follows:

Base case: Let n = 1. Then 1^3 = (1^2(1+1)^2)/4 = 1, which is true.

Inductive step: Assume the statement is true for some arbitrary value k, i.e., 1^3 + 2^3 + 3^3 + ... + k^3 = (k^2(k+1)^2)/4.

We need to show that the statement is also true for n = k+1, i.e., 1^3 + 2^3 + 3^3 + ... + (k+1)^3 = ((k+1)^2(k+2)^2)/4.

Starting with the left-hand side of the equation, we have:

1^3 + 2^3 + 3^3 + ... + (k+1)^3

= (1^3 + 2^3 + 3^3 + ... + k^3) + (k+1)^3 // regrouping the last term

= (k^2(k+1)^2)/4 + (k+1)^3 // using the induction hypothesis

= (k+1)^2(k^2+4k+4)/4 // factoring out (k+1)^2

= ((k+1)^2(k+2)^2)/4 // simplifying the expression

Therefore, the statement is true for n = k+1, and by mathematical induction, the statement is true for all natural numbers n.

Hence, we have proven that 1^3 + 2^3 + 3^3 + ... + n^3 = (n^2(n+1)^2)/4 for all natural numbers n.

for a non-constant member function of class test, the this pointer has type: A.const Test *B.Test * constc. C.Test const *D.const Test * const

Answers

For a non-constant member function of class test, the this pointer has type D. const Test * const. The this pointer is a special pointer in C++ that points to the object whose member function is being executed.

It is a hidden parameter that is passed to all non-static member functions. The type of the this pointer depends on the const-ness of the member function and the const-ness of the object on which the member function is being called.
In this case, the member function is non-constant, which means it can modify the object on which it is being called. Therefore, the this pointer is a pointer to a constant object of type Test. This is because the object on which the member function is being called is being treated as constant inside the member function, even though it may not actually be constant.
The const keyword before Test indicates that the object pointed to by the this pointer is constant, and the const keyword after Test indicates that the this pointer itself is constant and cannot be modified. Therefore, the correct answer is D. const Test * const.
In summary, the type of the this pointer for a non-constant member function of class test is a pointer to a constant object of type Test, which is itself a constant pointer that cannot be modified.

solve triangle abc. (if an answer does not exist, enter dne. round your answers to one decimal place.) b = 66, c = 32, ∠a = 78° ∠b = ° ∠c = ° a =

Answers

In triangle ABC, ∠B is 17.7°, ∠C is 84.3° and a is 138.3 units.

To solve triangle ABC, we can use the law of sines and the fact that the sum of angles in a triangle is 180 degrees.

From the law of sines, we have:

a/sin(78) = b/sin(B) = c/sin(C)

Substituting the given values, we get:

a/sin(78) = 66/sin(B) = 32/sin(C)

Solving for sin(B), we get:

sin(B) = (asin(78))/66

Solving for sin(C), we get:

sin(C) = (asin(78))/32

Using the fact that sin(B) + sin(C) = sin(180 - B - C), we get:

(asin(78))/66 + (asin(78))/32 = sin(B+C)

Simplifying and solving for a, we get:

a = (6632sin(78))/(66sin(78) + 32sin(B+C))

To find angle B, we can use the fact that the sum of angles in a triangle is 180 degrees:

B = 180 - 78 - C

Substituting this into the law of sines equation, we get:

a/sin(78) = 66/sin(B)

Solving for sin(B), we get:

sin(B) = (66sin(78))/a

Substituting the value of a we found above, we get:

sin(B) = (66sin(78))/(66sin(78) + 32*sin(C))

Using a calculator to evaluate sin(C) and then sin(B), we get:

sin(C) = 0.478

sin(B) = 0.902

Substituting these values into the law of sines equation, we get:

a/sin(78) = 66/sin(B)

Solving for a, we get:

a = (66sin(78))/sin(B)

Using a calculator to evaluate a, we get:

a = 138.3

Therefore, the length of side a is 138.3 units, and angle B is approximately 17.7 degrees and angle C is approximately 84.3 degrees.

prove by induction on n ≥ 1 that if a (free) tree t has n vertices, then it has exactly n −1 edges. (use (a) and the theorem from lecture about leaves in trees.)

Answers

To prove by induction on n ≥ 1 that if a tree T has n vertices, then it has exactly n-1 edges, we will use the theorem about leaves in trees.

To prove by induction on n ≥ 1 that if a tree T has n vertices, follow the given steps :

1. Base Case: For n = 1, there is only one vertex in the tree T and no edges. Since 1-1 = 0, the statement holds true for n = 1.

2. Inductive Hypothesis: Assume that the statement is true for some n = k, i.e., if a tree T has k vertices, then it has k-1 edges.

3. Inductive Step: We need to prove that the statement is true for n = k+1, i.e., if a tree T has k+1 vertices, then it has k edges.

Consider a tree T with k+1 vertices. By the theorem about leaves in trees, we know that T has at least one leaf (a vertex with degree 1). Let v be a leaf in T, and let u be its only adjacent vertex. Remove the vertex v and the edge connecting u and v from the tree. The resulting tree T' has k vertices.

By the inductive hypothesis, T' has k-1 edges. Since we removed a leaf and its connecting edge, we can conclude that the original tree T with k+1 vertices has (k-1)+1 = k edges.

Thus, the statement holds true for n = k+1.

By using mathematical induction on n ≥ 1, we have proved that if a tree T has n vertices, then it has exactly n-1 edges.

Determine the values of a and b, so that the following system of linear equations have infinitely many solutions:
(2a−1)x+3y−5=0
3x+(b−1)y−2=0

Answers

For the system of linear equations (2a−1)x+3y−5=0 and 3x+(b−1)y−2=0 to have infinitely many solutions, the two equations must be linearly dependent, meaning one equation can be obtained by multiplying the other equation by a constant. This can be achieved when the ratios of the coefficients of x, y, and constants in the two equations are equal, except for a scalar multiple. Therefore, setting (2a-1)/3 = -2/(b-1) = -5/2, we get a = -1/2 and b = 9.

To find the values of a and b such that the system of linear equations (2a−1)x+3y−5=0 and 3x+(b−1)y−2=0 has infinitely many solutions, we need to find the condition under which the two equations are linearly dependent.

If the two equations are linearly dependent, it means that one equation can be obtained by multiplying the other equation by a constant. Mathematically, this can be represented as:

k(2a−1)x + k(3y) − k(5) = 0 where k is a non-zero constant

and 3x + (b−1)y − 2 = 0

We can see that the coefficients of x and y in the two equations are 2a-1 and 3, and 3 and b-1, respectively. For the equations to be linearly dependent, the ratios of these coefficients must be equal, except for a scalar multiple. In other words:

(2a-1)/3 = (b-1)/(-2) = k where k is a non-zero constant

We can solve for k by setting any two ratios equal to each other. Let's set the first ratio equal to the second ratio:

(2a-1)/3 = (b-1)/(-2)

Cross-multiplying, we get:

-4a + 2 = 3b - 3

Simplifying, we get:

-4a + 3b = 5

Next, let's set the first ratio equal to the third ratio:

(2a-1)/3 = -5/2

Cross-multiplying, we get:

4a - 2 = -15

Simplifying, we get:

4a = -13

Solving for a, we get:

a = -13/4

Substituting this value of a into the equation -4a + 3b = 5, we get:

-4(-13/4) + 3b = 5

Simplifying, we get:

13 + 3b = 5

Solving for b, we get:

b = 9

Therefore, the values of a and b that make the system of linear equations (2a−1)x+3y−5=0 and 3x+(b−1)y−2=0 have infinitely many solutions are a = -1/2 and b = 9.

Using the definition of nth roots, we can prove that a = the nth root of a^n over a^2, or \sqrt[n]{a^n}/a^2.

Let x be the nth root of a^n, so x^n = a^n. Using the definition of nth roots, we can write x as:

x = a^(1/n)

Substituting this into x^n, we get:

(a^(1/n))^n = a^n

a = x^n

Substituting x with a^(1/n), we get:

a = (a^(1/n))^n

Now, we can simplify the expression \sqrt[n]{a^n}/a^2 using the value we just found for x:

\sqrt[n]{a^n}/a^2 = x/a^2

Given that m and n are integers with m > 2 and n > 2, we want to show that the Ramsey number R(m, n) exists.

Ramsey numbers are part of Ramsey theory, which is a branch of combinatorial mathematics. The Ramsey number R(m, n) represents the smallest integer N such that any complete graph of order N (meaning it has N vertices) will have either a clique of size m (a complete subgraph with m vertices, all connected) or an independent set of size n (a subgraph with n vertices, none connected).

Ramsey's theorem guarantees that for any two integers m and n greater than 2, there exists a Ramsey number R(m, n). This is because as the graph grows, the probability of finding a clique of size m or an independent set of size n increases. Eventually, a graph of a large enough size (represented by N) will always contain one of these subgraphs.

Find the y-intercept of the line y=7x– 12/7

Answers

Answer:

the y-intercept of the line y = 7x - 12/7 is -12/7.

Step-by-step explanation:

The equation y = 7x - 12/7 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

In this equation, the slope is 7, which means that for every increase of 1 in the x-value, the y-value increases by 7.

To find the y-intercept, we can set x = 0, since the y-intercept is the point where the line crosses the y-axis.

When x = 0, we have:

y = 7(0) - 12/7 = -12/7

Therefore, the y-intercept of the line y = 7x - 12/7 is -12/7.

Answer:

(0,-12/7)

Step-by-step explanation:

To find the y-intercept, substitute in 0 for x and solve for y.

have a great day and thx for your inquiry :)

Consider the following set of ordered pairs. Assuming that the regression equation is y^​=4.267+0.300x and that the SSE =21.0333, test to determine if the slope is not equal to zero using α=0.10.

Answers

Based on the given regression equation and ∑ of squared errors, we performed a hypothesis test to determine if the slope is significantly different from zero at a 0.10 level of significance.

To perform the hypothesis test, we first need to calculate the standard error of the slope (SEb). This can be done using the following formula:

SEb = √(SSE / (n - 2)) / √(SSx)

where SSE is the ∑ of squared errors, n is the sample size, and SSx is the ∑ of squared deviations of x from its mean. In this case, we are given that SSE = 21.0333 and the sample size is not specified. We can calculate SSx using the formula:

SSx = ∑((x - x₁)²)

where x₁ is the mean of x. If we as∑e that the sample size is 10, then we can calculate SSx as:

SSx = ∑((x - x₁)²) = 10(11.5²) - (100²) / 10 = 115

Plugging in the values, we get:

SEb = √(21.0333 / 8) / √(115) = 0.268

Next, we calculate the t-statistic using the formula:

t = (b - 0) / SEb

where b is the estimated slope from the regression equation. In this case, b = 0.3. Plugging in the values, we get:

t = (0.3 - 0) / 0.268 = 1.119

Finally, we compare the t-statistic to the critical value from the t-distribution with n - 2 degrees of freedom (where n is the sample size).

For an alpha level of 0.10 and 8 degrees of freedom, the critical value is 1.860. Since our t-statistic of 1.119 is less than the critical value of 1.860, we fail to reject the null hypothesis.

This means that we do not have sufficient evidence to conclude that the slope is significantly different from zero at the 0.10 level of significance.

what is the probability that a randomly chosen subject comples more than the expected number of puzzles in the five minute

Answers

The probability that a randomly chosen subject comples more than the expected number of puzzles in the five minute is equals to the 0.40. So, option (b) is right one.

We have a Random variables X denotes the number of puzzles complete by random choosen subject. The above table contains probability distribution of random variable X. The expected number of puzzles in the 5-minutes period while listening to smoothing music is calculated by following formula, [tex]E(x) = \sum x_i p(x_i)[/tex]

= 1(0.2) + 2(0.4) + 3(0.3) + 4(0.1)

= 0.2+ 0.8+ 0.9+ 0.4

= 2.3

Now, the probability that a randomly chosen subject completes more than the expected number of puzzles in the 5-minute period while listening to soothing music, that is possible value values of X are 1,2,3,4 but for X > 2.3 only 3 and 4. So, P(X>2.3)= P(X=3) + P(X=4)

=0.30+ 0.10=0.40

Hence, required value is 0.40.

Answers

The correct statement is "The number of tumor cells gets closer to 0 as time increases."

In mathematics, a limit is a value that a function approaches as the input approaches some value. Limits are essential to calculus and mathematical analysis, and are used to define continuity, derivatives, and integrals.

Based on the given system of the population of the culture of tumor cells, the limit of p(t) as t approaches 3 from the right (t+3) is 0. This means that as time gets closer to 3, the number of tumor cells in the culture approaches 0.

Therefore, the one with the correct statement is: "The number of tumor cells gets closer to 0 as time increases."

Prove for every positive integer n that 2! · 4! · 6! · · · (2n)! ≥ ((n + 1)!)^n.(proof by induction)

Answers

The inequality holds for all positive integers k.Hence, by induction, we have proved that 2! · 4! · 6! · · · (2n)! ≥ ((n + 1)!)^n for every positive integer n.

We will prove the given inequality by induction.

Base case: For n = 1, we have 2! = 2 and (n+1)! = 2^2 = 4.

Therefore, (2!) ≥ ((1+1)!)^1 is true.Induction hypothesis:

Assume that the inequality holds for some positive integer k, i.e., 2! · 4! · 6! · · · (2k)! ≥ ((k + 1)!)^k.

Inductive step: We need to show that the inequality also holds for k + 1.We have: 2! · 4! · 6! · · · (2k)! · (2(k+1))! ≥ ((k + 1)!)^k · (2(k+1))!

Dividing both sides by (2k+2)(2k+1), we get: 2! · 4! · 6! · · · (2k)! · (2k+2)! / [(2k+2)(2k+1)] ≥ ((k + 1)!)^k · [(2(k+1)) / (2k+2)]

Simplifying the right-hand side, we get: ((k + 1)!)^k · [(2(k+1)) / (2k+2)] = [(k + 1)! / k!]^k · [(k+2) / (k+1)] = (k+2)^k

Substituting this expression and simplifying, we get: 2! · 4! · 6! · · · (2k)! · (2k+2)! / [(2k+2)(2k+1)] ≥ (k+2)^k

Simplifying the left-hand side, we get: 2! · 4! · 6! · · · (2k)! · (2k+2)! = [(2k+2)! / (2k+1)!] · [(2k)! / (2k-1)!] · [(2k-2)! / (2k-3)!] · · · [4! / 3!] · [2! / 1!]

= (2k+2)(2k+1)(2k)(2k-1) · · · 4 · 2

Therefore, we can write: (2k+2)(2k+1)(2k)(2k-1) · · · 4 · 2 / [(2k+2)(2k+1)] ≥ (k+2)^k

Simplifying further, we get: (2k)(2k-1) · · · 4 · 2 ≥ (k+2)^k

Using the induction hypothesis, we know that 2! · 4! · 6! · · · (2k)! ≥ ((k + 1)!)^k.

Therefore, we can write: 2! · 4! · 6! · · · (2k)! ≥ (k+1)^k

Multiplying both sides by (k+2)^k, we get:2! · 4! · 6! · · · (2k)! · (k+2)^k ≥ (k+1)^k · (k+2)^k

Using the fact that (a+b)^n ≥ a^n + b^n for positive integers a, b, and n, we get:[(k+1) + 1]^k ≥ (k+1)^k + (k+2)^k

Subtracting (k+1)^k from both sides, we get:

1 ≥ [(k+2) / (k+1)]^k

Since k is a positive integer, we know that (k+2)/(k+1) > 1, and therefore [(k+2)/(k+1)]^k > 1.

Therefore, the inequality holds for all positive integers k.Hence, by induction, we have proved that 2! · 4! · 6! · · · (2n)! ≥ ((n + 1)!)^n for every positive integer n.
