A sports medicine major wants to conduct a experiment to determine if there there's a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:

Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The table shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for seven randomly selected players. What is the equation of the line best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? Round any values to the nearest tenth, if necessary.
leg press (reps) 12 | 32 | 7 | 11 | 23 | 28 | 15 |
40-yard dash (s) 8.6 | 14.6 | 7.1 | 8.3 | 11.9 | 13.4 | 9.5 |

Answers

Answer 1

Answer:

The correct answer is the equation of the line of best fit is y=0.11x+4.54, and it would take the player 6.96 seconds to run.

Explanation:

Using technology, we calculate the line of best fit; we first enter the data points as a scatter plot, then run the regression tool, which gives us y=ax+b, where a=0.11 and b=4.54.

We now use this equation, y=0.11x+4.54, to calculate the amount of time it would take a player to run 40 yards if the player can do 22 leg-press reps:

y=0.11(22)+4.54=6.96.

B. If garden peas had used sperm and egg to reproduce
C. Being short is a recessive trait
D. If seed color and shape were located on the same chromosome

Answers

Answer:

D. If seed color and shape were located on the same chromosome

Explanation:

If seed color and shape were located on the same chromosome, they would not be inherited independently of one another.

Genes on the same chromosome are more likely to be inherited together. The only way they could be inherited independently is if crossing over occurred between the two genes.

Therefore, this would argue against Mendel's law of independent assortment.

For the initial year of a summer camp, 56 girls and 64 boys enrolled. Each year thereafter, 18 more students enrolled in the camp. Let t be the time (in years) since the camp opened. Part A: Write a function rule for the total number of students enrolled t years after the camp opened.

Answers

Answer:

[tex]f(t)=120+18t[/tex]

Explanation:

We know that for the initial year of a summer camp, 56 girls and 64 boys enrolled.

The total children enrolled for the initial year can be calculated as :

[tex]56+64=120[/tex]

Each year, 18 more students enrolled in the camp.

The variable ''[tex]t[/tex]'' represents the time in years since the camp opened.

The following expression :

[tex]18t[/tex]  

represents the extra children enrolled each year

If we sum, we can obtain the following expression :

[tex]120+18t[/tex]

which is the function [tex]f(t)[/tex] for the total number of students enrolled [tex]t[/tex] years after the camp opened.

The function rule is [tex]f(t)=120+18t[/tex]

For example, when [tex]t=0[/tex] ⇒

[tex]f(0)=120+18(0)=120[/tex]

which is the original amount of enrolled children when the summer camp opened.

When [tex]t=3[/tex] ⇒

[tex]f(3)=120+18(3)=174[/tex]

which is the expected value for the total number of students enrolled 3 years after the camp opened.

Fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. The height of the pea plants is recorded daily. What is the independent variable?


A) the different amounts of water

B) the heights of the pea plant

C) the pea plants

D) the natural ways of receiving water

Answers

Answer: The independent variable is the different amount of water. The correct option is A.

Explanation:

A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:

--> Dependent variable and

--> Independent variable.

Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:

--> the height of the plant,

--> the size of the plant,

--> the number of leaves

---> if the plant survived or not (dead).

Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!

Answers

Answer:

1) Transcription Bubble.

2) Replication Forks

3)

Explanation:

1) The region of opened- up DNA is called a Transcription Bubble. In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complentary RNA transcript.

2) The Replication Forks hold the 2 separated strands of DNA apart, preventing then from assuming their double helix shape... in order  to replicate all your DNA its faster to replicate DNA if your doing it in many different areas at the same.

3)Since DNA polymerase requires a free 3` OH group  for initiation of synthesis, it can synthesize in only one direction by extending the 3` end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3`-5` direction, and the daughter strand is formed in a 5`-3` direction.

What is DNA replication?

A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

A particular kind of enzyme called DNA polymerase (DNAP) is in charge of creating fresh nucleic acid molecules that are copies of the original DNA. Polymers are huge compounds consisting of smaller, repeating units that are chemically linked to one another. Nucleic acids are polymers.

Answers

Answer:

Crestas mitocondriales, poros de la membrana nuclear y las capas lipídicas que forman la membrana plasmática no son visibles al microscopio óptico.

Explanation:

El límite de resolución de un microscopio óptico es de, aproximadamente, de 0,2 μm (es decir 10⁻⁶ m). Es decir, que en un microscopio óptico sólo podrán verse células y estructuras celulares mayores a 0,2 μm, y en algunos casos serán visibles sólo con tinciones especiales.

Por ende, entre las cuatro estructuras que se nos presentan en el problema sólo los cromosomas de una celula animal condensados durante la mitosis pueden verse al microscopio óptico.

Tanto las crestas mitocondriales como los poros de la membrana nuclear y las capas lipídicas que forman la membrana son estructuras muy pequeñas y visibles solamente al microscopio electrónico.

Stomata allow plants to absorb [tex]CO2[/tex] from the atmosphere. Water is taken from the earth by plants and transmitted to their leaves via their roots. The only source of light that the chlorophyll and other green parts of the plant absorb is sunlight.

Plants use sunlight, water, and carbon dioxide to perform photosynthesis.

They produce Chlorophyll, the pigment that makes plants green, by using stored carbon, hydrogen from water, and magnesium from the soil. They make Adenosine triphosphate, which is vital in energy transfer, by combining phosphorus, oxygen, and carbon.
