Answer:
Simple linear equation is :
Y = 86.784 - 2.67x
Step-by-step explanation:
The educator wants to see the relationship between no of absences and final grades of the student. No. of absence of student is independent variable while final grade is dependent variable. The final grades of the student are dependent on the no. of absence they do.
b = Sxy / Sxx
b = { 2312 [ 37 * 422 ] / 6 } / 337 - 37^2 / 6 = -2.67
a = -2.67 * 37/6 = 86.784
Answer:
The phenotypic ratio of the offspring will be 100% of purple flowers.
Step-by-step explanation:
Mendel's first law states that if two pure lines are crossed for a given character, the descendants of the first generation will all be equal to each other, phenotypically and genotypically, and phenotypically equal to one of the parents (of dominant genotype).
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
We represent the possibilities of hybridization using a Punnett square in the attached picture.
Uppercase letters represent dominant alleles and lowercase letters represent recessive alleles.
Homozygous individuals have the same pair of alleles. (AA, aa)
We can verify that all offspring have a dominant allele, therefore all offspring will have purple flowers.
I say B quantity to figure out the value in the data
Hope this helps!!
First we will compute the h+k and then multiply the result by 2.
To add polynomials, we add terms whose variables are alike, for example:
we add the coefficients of x^2 together, the coefficients of x together and so on.
Therefore:
h + k = x^2 + 1 + x - 2 = x^2+x-1
Now, we will multiply this answer by 2 to get the final answer:
2(h+k) = 2(x^2+x-1) = 2x^2 + 2x -2
