Answer:
C. Jamila is correct because glucose is a product, not a reactant, of photosynthesis.
Step-by-step explanation:
Photosynthesis is a process that occurs in plants and some other organisms in which energy from sunlight is used to convert carbon dioxide and water into glucose (a sugar) and oxygen. In this process, carbon dioxide and water are the reactants, and glucose and oxygen are the products. Therefore, Anton is incorrect and Jamila is correct because glucose is a product of photosynthesis, not a reactant.

Sum of interior angles of a 6-sided polygon is:
180°(6 - 2) = 180°*4 = 720°Both angles ∠X and ∠Y marked as same, let them be x and ∠W is marked as right angle.
The sum is:
2x + 90 + 99 + 171 + 159 = 7202x + 519 = 7202x = 201x = 100.5m∠X = m∠Y = 100.5°.
Answer:
m∠X = 100.5°
m∠Y = 100.5°
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.3cm}\underline{Sum of the interior angles of a polygon}\\\\$S=(n-2) \times 180^{\circ}$\\\\where:\\ \phantom{ww}$\bullet$ $n$ is the number of sides. \\ \end{minipage}}[/tex]
The given polygon has 6 sides.
Therefore, the sum of its interior angles is:
[tex]\implies S = (6 - 2) \times 180^{\circ} = 720^{\circ}[/tex]
From inspection of the given polygon:
m∠V = 99°m∠Z = 171°m∠U = 159°m∠W = 90°m∠X = m∠YTherefore:
[tex]\implies m \angle U + m \angle V + m \angle W + m \angle X + m \angle Y + m \angle Z = 720^{\circ}[/tex]
[tex]\implies 159^{\circ} + 99^{\circ} + 90^{\circ} + m \angle X + m∠ \angle Y + 171^{\circ} = 720^{\circ}[/tex]
[tex]\implies m \angle X + m \angle Y + 519^{\circ} = 720^{\circ}[/tex]
[tex]\implies m \angle X + m \angle Y = 201^{\circ}[/tex]
As m∠X is equal to m∠Y:
[tex]\implies m \angle X = m \angle Y = 201^{\circ} \div 2 = 100.5^{\circ}[/tex]

22. A survey was given to 90 high school students. They were asked if they preferred fiction or non-fiction and if they preferred indoor or outdoor activities. Partial survey results are shown in the table.
What percent of students in the survey, to the nearest whole number, prefer outdoor activities given they prefer non-fiction?
Enter a number in the box.
P(outdoor | non−fiction)= ______%
Note that the percentage of the students in the survey, to the nearest whole number, that prefer outdoor activities given they prefer non-fiction is: 11%.
What is the rationale for the above response?To get the percentage of those who love outdoor activities as well as non-fiction, we must complete the table.
Given:
Total number of those who love Fiction and Non Fiction but who love indoors = 50
From that list those who love fiction = 24, thus, those who love indoor and non-fiction =
50 - 24 = 26
Total number of those who were served are = 90
If the total number of those who love Fiction and Non-Fiction but who love indoors = 50
Then the total number of those who love Fiction and Non Fiction but who love Outdoors = 90 - 50 = 40
If the total number of those who love outdoor (Fiction and non-fiction) = 40 and those who prefer fiction only from this category is = 30;
Then the total number of those who love Non Fiction but who love Outdoors =
40 -30
= 10
Thus, the percentage of this number against the total number of those surveyed is:
10/90
= 0.1111111111 or 11%
Therefore, the percentage of students in the survey, to the nearest whole number, prefer outdoor activities given they prefer non-fiction is given as 11%. See the full table attached.

CONSTRUCTION Every 128 fluid ounces of
stain covers about 200 square feet of wood.
About how many fluid ounces of stain
does a homeowner need to stain the beam
shown? (Assume the back of the beam does
not need to be stained.)
Don’t look at 17 nor the pink rectangle pls!! HELPP :(
Answer:
6.08 fluid ounces
Step-by-step explanation:
You want the amount of stain required to cover the surface area of the ends and three sides of a beam 6" square and 6 ft long. 128 floz of stain will cover 200 square feet.
End areaThe two ends of the beam are 1/2 ft square, so the area of each is ...
A = s² = (1/2 ft)² = 1/4 ft²
The two ends have a total area of ...
2 × (1/4 ft²) = 1/2 ft² . . . . end area
Side areaThree of the four sides of the beam are to be stained, so their total area is the area of 3 rectangles, each of which is 1/2 ft by 6 ft.
The area of each rectangle is ...
A = LW
So, the area of the three rectangles is ...
total side area = 3 × (1/2 ft)(6 ft) = 9 ft²
Beam areaThen the area to be stained is the sum of the end area and the side area:
stained area = (1/2 ft²) +(9 ft²) = 9.5 ft²
Stain quantityThe amount of stain required is proportional to the area, so we can write the proportion ...
q/(9.5 ft²) = (128 floz)/(200 ft²)
Multiplying by 9.5 ft² gives ...
q = (128 floz)(9.5/200) = 6.08 floz
The homeowner needs 6.08 fluid ounces of stain to stain the beam.

Suppose that 7 boys and 13 girls line up in a row. Let $S$ be the number of places in the row where a boy and a girl are standing next to each other. For example,for the row $GBBGGGBGBGGGBGBGGBGG$ we have $S=12$. If all possible orders of these $20$ people are considered,what is the average value of $S$?
(a) 9 (b) 10 (c) 11 (d) 12 (e) 13
Answer:
[tex]$\boxed{(c) : 11}$[/tex]
Step-by-step explanation:
We can think of this problem as placing $7$ dividers (representing the boys) in $20$ slots (representing the people). Thus, the number of ways to arrange the boys and girls is the number of ways to place the dividers, which is $\binom{20}{7}$.
To find the average value of $S$, we need to find the total number of arrangements where $S = k$ for each possible value of $k$, then divide by the total number of arrangements.
Let's first consider the case where $k=0$. There is only $1$ way to arrange the boys and girls such that there are no boys and girls standing next to each other: BBBBBBBBBBBBBBBBBBBBB.
Next, let's consider the case where $k=1$. There are $\binom{7}{1}\binom{13}{6}$ ways to arrange the boys and girls such that there is exactly $1$ pair of boys and girls standing next to each other. To see this, consider that there are $\binom{7}{1}$ ways to choose the position of the divider that separates a boy and a girl, and $\binom{13}{6}$ ways to arrange the remaining dividers and slots.
We can continue this process to find the total number of arrangements for each possible value of $k$. When we add up all of these arrangements and divide by the total number of arrangements, we get the average value of $S$.
More specifically, the average value of $S$ is equal to
[\frac{1\cdot1+\binom{7}{1}\binom{13}{6}\cdot1+\binom{7}{2}\binom{13}{5}\cdot2+\binom{7}{3}\binom{13}{4}\cdot3+\binom{7}{4}\binom{13}{3}\cdot4+\binom{7}{5}\binom{13}{2}\cdot5+\binom{7}{6}\binom{13}{1}\cdot6+\binom{7}{7}\binom{13}{0}\cdot7}{\binom{20}{7}}.]

So, the y-intercept is (0, 10)
How the graph behaves (end behaviour)To do this, we check the values of x in relation to the values of y
From the graph, we can see that the values of y reduces as the values of x increases to 20
This means that the end behaviour is
As x ⇒ +20, y ⇒ 0 and As x ⇒ -∝, y ⇒ +∝
Possible values of variablesTo do this, we again check the values of x in relation to the values of y
From the graph, we can see that the values of y when x = 0 is 10 and also, we have x = -50 and y = 15
So, the possible values are (0, 10) and (-50, 15)
