- Teacher's comment: I think you have the right idea, but you need to be more careful with your language.
Explanation:
A line segment is <u>part of a line</u> that connects points. It limited consequently, it has length.
- Duru's definition: A line segment is a line connecting two endpoints
It is missing that it is just a part of the line. A ray also connects two points but extends infinetly in one direction. Thus, Duru's definition is not so specific.
That justifies teacher's comment:
- Teacher's comment: What you've written is true, but it isn't a correct definition. A ray would also fit your defenition
Second definition:
- Oliver's definition: A line segment is when three points are all on the same line.
The constraint of a line segment to three points all on the same line corresponds to collinear points. Two points always form a line,, but three points lie on a line only in they are collinear.
That justifies, theacher's comment:
- Teacher's comment: Were you thinking of the team collinear?
Third definition:
- Carlos' definition: A line segment is part of a line, not the whole thing.
Mathematicall language is formal. You must use precise words. An expression as 'whole thing" is not formal.
That justifies teacher's comment:
- Teacher's comment: I think you have the right idea, but you need to be more careful with your language.
Answer:
Stomata would not open and close.
Explanation:
This is the answer because guard cells play an important function of controlling stomata. The ensures that stomata are open during the day and closed during the night for the purposes of photosynthesis. The stomata are the pores that are found on the under surface of a plant leave,whose role is gaseous exchange.
The main function of guard cells is to regulate the opening and closing of the pore formed between the gap of two guard cells, termed as stomata.
- Option A is incorrect as stomata are the least susceptible area from where pathogens can enter the plant cell.
- Option B is incorrect because photosynthesis is not directly and much affected by guard cells.
- Option D is incorrect as chloroplasts are not associated with the guard cells.
- Stomata are directly linked with movement of guard cells, so correct answer is option C. Through stomata, exchange of gases and water vapor takes place.
Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
<h3>What is the discrete probability distribution?</h3>
Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:
The probability that he buys fewer than 3 packs is given by:
P(X < 3) = P(X = 1) + P(X = 2).
Hence:
P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.
There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
