What is the ANOVA?

This is the term that is used to refer to the short form of the term that says analysis of variance.

The ANOVA is used to show the variation that would be in existence of a group of observations.

The F test is known to be positively skewed at all times. So we would have it that the P value would have to be to the right and not to the left in the ANOVA hypothesis.

Using F Statistics table , we can calculate Critical point using a 0.01 level of significance.

Hence,4.4306 is the critical point using a 0.01 level of significance, that one would compare to the f statistic in order to make a conclusion.

3:1 phenotype ratio means that three offspring will have a dominant phonotype. Then there is one offspring that will have a recessive genotype, and thus the recessive phenotype.

A 3:1 ratio is the relative fraction of phenotypes among progeny (offspring) results following mating between two heterozygotes, where each parent possesses one dominant allele and one recessive allele at the genetic locus in question.

A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another.

Answer:

  A: line 3 to 4; distributive property was incorrectly applied

  B: line 8 to 9: division by a negative number was incorrect

Step-by-step explanation:

You want to know where errors occurred in the solution of the given inequality, and what the errors were.

The first error occurred going from line 3 to line 4.

Expressions 2(x -2) and 3(x -4) were incorrectly evaluated as 2x-2 and 3x-4. The distributive property requires the factor to be applied to all of the terms in parentheses, not just the first one.

The second error occurred going from line 8 to line 9.

The inequality -5x ≤ -11 was incorrectly divided by -5 to get x ≤ 11/5. Multiplication or division of an inequality by a negative number is an order-reversing operation, so requires the comparison symbol be reversed.

Distributive property

The student could be asked to group some dissimilar objects, then tell what must happen to make two such groups, or three such groups. This can be compared to groups identified by parentheses, with 2 or 3 as a multiplier.

Ordering

The student can be asked to order a pair of numbers, then the same numbers with opposite signs.  The direction of the comparison symbol should be noted in each case. (-1 > -2; 1 < 2) Multiplication or division by a negative can be seen as changing the signs of the things being compared.

 A: line 3 to 4; distributive property was incorrectly applied

 B: line 8 to 9: division by a negative number was incorrect

Expression: An expression is made up of operators, constants, and variables. An expression can be made up of one or more operands and one or more operators to yield a value.

A. First error

The first error occurred going from line 3 to line 4.

Expressions 2(x -2) and 3(x -4) are incorrectly evaluated as 2x-2 and 3x-4. The distributive property requires the factor to be applied in all of the terms in parentheses, not just the first one.

B. Second error

The second error occurred going from line 8 to line 9.

In the given question, we have to Select from the three alternative methods of overhead allocation in the drop down list so that it matches with the provided feature.

Item #1 Plant Wide rate

Item #2 Departmental rate

Item #3 Activity based costing

Plant Wide rate: Whenever a corporation assigns all of its production overhead costs to products or cost items, it does so using a single overhead rate known as the plant wide overhead rate. In smaller companies with predictable cost structures, it is most frequently used.

Departmental rate: The overhead rate per unit of activity that is charged by a certain department is known as a departmental rate. Only the production departments charge this rate. Administrative departments don't have departmental rates because their expenses are paid as they are incurred.

Activity based costing: Activity based costing(ABC) is a mechanism for allocating overhead and indirect costs to goods and services, such as salaries and utility prices. The ABC approach of cost accounting is based on activities, which are seen as any occasion, unit of labour, or assignment with a particular goals.

The binomial distribution summarizes the number of trials or observations when each trial has the same chance of achieving a specific value. The binomial distribution determines the likelihood of observing a given number of successful outcomes in a given number of trials.

In a posthumous proof published in 1713, Swiss mathematician Jakob Bernoulli determined that the probability of k such outcomes in n repetitions is equal to the kth term (where k starts with 0) in the expansion of the binomial expression (p + q)n, where q = 1 p.
