Two inbred varieties of butternut squash are bred and the progeny are then self-fertilized. The mean length and variance of squash size for each generation is shown below. The growth conditions were kept the same in each generation. Mean Length (em) Variance (cm) Parenti 40 Parent II 90 F1 65 F2 65 49 49.4 45 32. What is the environmental variance (in cm)? A) 0 B) 2 C) 4 D) 5 E) 7

Answers

Answer 1

The environmental variance in this case is 5 cm, which corresponds to option D.

To determine the environmental variance, we need to subtract the genetic variance from the total variance. The total variance can be calculated by taking the average of the variances in each generation.

Total variance = (49 + 49.4 + 45 + 32) / 4 = 175.4 / 4 = 43.85 cm

The genetic variance is the variance that is due to the genetic differences between the parent varieties and their progeny. In this case, the genetic variance is calculated by taking the difference between the mean length of the F1 generation and the mean length of the parent varieties, squared.

Genetic variance = (65 - [tex]((40 + 90) / 2))^{2}[/tex]= [tex](65 - 65)^{2}[/tex] = 0

The environmental variance is then obtained by subtracting the genetic variance from the total variance:

Environmental variance = Total variance - Genetic variance = 43.85 - 0 = 43.85 cm

- The winning time increased by an average of 0.4 second per year from year 2 to year 4.

- The winning time increased by an average of 0.475 second per year from year 2 to year 4.

Answers

Answer: The winning time increased by an average of 0.4 second per year from year 2 to year 4.

The winning time for a race displayed in the table would be:

C). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Find the increase in winning time:

Given that,

Year                             Winning Time(seconds)

1                                          27.5

2                                         28.4

3                                         28.7

4                                         29.2

5                                         29.44

Hence, The total change in the time is,

= (0. + 0.3 + 0.5 + 0.24)/4

= 0.485 seconds

Now, If we round off, it becomes 0.5 seconds.

Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.

Thus, ''Option C'' is the correct answer.

The total circular area a sprinkler can water is 240 2 . The sprinkler is set to rotate back and forth in a 75° pattern. Find the amount of area that will get watered.

Answers

Answer:

The sprinkler will cover an area of [tex]50m^2[/tex]

Step-by-step explanation:

Given

[tex]Area = 240m^2[/tex]

[tex]\theta = 75^{\circ}[/tex]

Required

Determine the amount of area it can cover

The amount of area is calculated by calculating the area of a sector using:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * \pi r^2[/tex]

Where:

[tex]Area = \pi r^2 = 240m^2[/tex]

So, we have:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * 240m^2[/tex]

Substitute 75 for [tex]\theta[/tex]

[tex]Sector\ Area =\frac{75^{\circ}}{360^{\circ}} * 240m^2[/tex]

[tex]Sector\ Area =\frac{75^{\circ}* 240m^2}{360^{\circ}}[/tex]

[tex]Sector\ Area =\frac{75* 240m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000}{360} m^2[/tex]

[tex]Sector\ Area =50m^2[/tex]

Hence, the sprinkler will cover an area of [tex]50m^2[/tex]

Barry wants to make a drawing that is 1/2 the size of the original. If a tree in the original drawing is 11 inches tall and 5 inches wide,

Answers

Answer:

Barry's drawing is  5.5 in  tall and 2.5 in wide.

Step-by-step explanation:

We are given that

Height of tree, h=11 in

Width of tree, b=5 in

We have to find the size of the original.

Size of drawing is 1/2 size of the original

Therefore,

Height of drawing, h'=[tex]\frac{1}{2}\times 11[/tex]in

Height of drawing, h'=5.5 in

Width of drawing tree=[tex]\frac{1}{2}\times 5[/tex]

Width of drawing tree=[tex]2.5in[/tex]

Hence, Barry's drawing is  5.5 in  tall and 2.5 in wide.
