Note that the complete sentence is given as follows:
Photosynthesis is a process in which plants prepare food using carbon dioxide, chlorophyll, and water in the presence of sunlight.
During photosynthesis, light energy is transformed into chemical energy.
Why is Photosynthesis important?On a daily basis, humans rely on photosynthesis to create food as well as energy to provide heat, light, and power. Furthermore, because autotrophs are producers in practically all food chains, this method is crucial for humans as well.
Photosynthesis is the process by which plants convert water, sunshine, and carbon dioxide into oxygen and simple sugars that they may utilize as fuel. These fundamental producers serve as the foundation of an ecosystem, fueling the subsequent trophic levels. Life on Earth as we know it would not be conceivable without this process.

A company ordered $400 worth of muffins. Bran muffins cost $2 each and blueberry muffins cost $4 each. If the company ordered twice as many blueberry muffins as bran muffins , how many muffins were ordered total
Answers
Answer:
40 Bran Muffins
80 Blueberry Muffins
Explanation:
Let the number of Bran muffins ordered = x
The number of Blueberry muffins ordered = 2x (it is given that the number of blueberry muffins is twice the number of bran muffins)
The cost of Bran muffins ordered = Number of Bran muffins * cost of 1 muffin
Cost of Bran muffins ordered = x * 2
Cost of Bran Muffins ordered = $ 2x
The cost of Blueberry muffins ordered = Number of Blueberry muffins * Cost of 1 blueberry muffin
Cost of Blueberry muffins ordered = 2x * 4
Cost of Blueberry muffins ordered = $ 8x
Since the sum of costs of Blueberry and Bran muffins is $400
Cost of Bran muffins + Cost of Blueberry muffins ordered = 400
2x + 8x = 400
10x = 400
x = 40
Hence, the number of Bran muffins ordered is 40
we are told that the number of Blueberry muffins is twice the number of Bran muffins
So,
Blueberry muffins = Bran muffins * 2
Blueberry Muffins = 40 * 2
Blueberry muffins = 80
So, the number of Blueberry muffins is 80

“An investigation to see if people who regularly watch football are better at remembering a football score than people who never watch football.” What is the null hypothesis and what is the Directional alternative hypothesis.
Answers
Note that the alternative directional hypothesis (HA) in this case is "There is no statistically significant difference in the ability to remember a football score between people who watch football regularly and people who never watch football."
Why is this so ?To examine whether there exists a significant difference in the ability to recall a football score between frequent and non-frequent viewers of football, the null hypothesis ( H0) assumes that no such difference exists.
In a statistical inference experiment, the alternative hypothesis is a statement. It is opposed to the null hypothesis and is symbolized by Ha or H1. It is also possible to define it as an alternative to the null. An alternative theory is a proposition that a researcher is testing in hypothesis testing.

Write an equation of a quadratic equation that has x-intercepts: 3, 6 and point (2, -2). (Intercept Form)
Answers
(x - 3)(x - 6) = 0
Expanding this equation gives:
x^2 - 9x + 18 = 0
Now we need to use the point (2, -2) to find the equation in intercept form.
First, substitute x = 2 and y = -2 into the standard form of a quadratic equation:
y = ax^2 + bx + c
-2 = a(2)^2 + b(2) + c
-2 = 4a + 2b + c
Next, substitute the x-intercepts into the equation:
y = a(x-3)(x-6)
We want the equation in intercept form, so we expand this equation:
y = a(x^2 - 9x + 18)
y = ax^2 - 9ax + 18a
Now we can use the three points we have to form a system of equations:
-2 = 4a + 2b + c
0 = 9a - 54a + 18a
0 = 3a
The last equation tells us that a = 0, which means the quadratic equation is a linear equation:
y = bx + c
To solve for b and c, we use the other two equations:
-2 = 4a + 2b + c
0 = 9a - 54a + 18a
Plugging in a = 0 into the first equation, we get:
-2 = 2b + c
Simplifying the second equation gives:
0 = -27a
Since a = 0, this equation is true and does not give us any new information.
We can now solve for b and c by solving the system of equations:
-2 = 2b + c
0 = -27a
Since a = 0, we can ignore the second equation and solve for b and c using the first equation:
2b + c = -2
We still have one degree of freedom, so we can choose any value for b and solve for c. Let's choose b = 1:
2(1) + c = -2
c = -4
Therefore, the equation of the quadratic function in intercept form is:
y = (x-3)(x-6)
or
y = x^2 - 9x + 18
which has x-intercepts at 3 and 6 and passes through the point (2, -2).

A classic counting problem is to determine the number of different ways that the letters of broccoli can be arranged. Find that number.
Answers
Answer:
10080
Explanation:
To find the number of different ways that the letters of the word "broccoli" can be arranged, we can use the concept of permutations. The word "broccoli" has 8 letters, including 2 "o"s, and 2 "c"s.
To calculate the number of arrangements, we need to consider the total number of letters and account for any repetitions. We can use the formula for permutations with repeated elements:
n! / (n1! * n2! * ... * nk!)
Where:
n is the total number of elements
n1, n2, ..., nk are the number of repetitions for each element
In this case, the word "broccoli" has a total of 8 letters, with 2 "o"s and 2 "c"s. Substituting these values into the formula, we get:
8! / (2! * 2!)
Calculating this expression:
8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40,320
2! = 2 * 1 = 2
(40,320) / (2 * 2) = 40,320 / 4 = 10,080
Therefore, there are 10,080 different ways that the letters of the word "broccoli" can be arranged.
Answer:
The letters of the word "BROCCOLI" can be arranged in 10,080 different ways.
Calculating Arrangements :
The two counting terms in mathematics are Permutations and Combinations
Combinations are used in finding the number of ways of selecting a set of items from the given set.
Permutations are used to find the number of arrangements after selection from a given set of items.
The formulation of arranging and selecting 'r' items from 'n' items is:
Here, we need to find the number of arrangements using the letters of the word "BROCCOLI". So, we need to use Permutation. Also, the arrangement involves no selection as all the letters are to be used, we have n = r.
The total letters in the word "BROCCOLI" = 8
The unique letters in the word "BROCCOLI" are: B, R, L, I i.e. (4)
The other letter repetitions are :
The letter 'O' appears twice i.e. 2
The letter 'C' appears twice i.e. 2
So, the number of different arrangements possible are :
= Total arrangements / Arrangements reduce due to duplicate letters
Hence, the letters of the word Broccoli can be arranged in 10,080 ways.

2. For the numbers 13, 16, 12, 11, 8, 14, 12, and 18 Which of the following is true? Mean> median > mode. Median> mean > mode Mode > mean> median 8, 11, 12, 12, 13, 14, 16, 18
3. The numbers 7, 6, 10, 13, 7, 2, 5, 6, and x have only one mode and the mean median and mode are all equal. what is the valve of x ?
Answers
Answer:
Therefore, the missing value is x = 7.
Explanation:
1. To find the average time it takes to fill a pallet, we can calculate the mean of the recorded times.
Mean = (35 + 36 + 32 + 42 + 58 + 56 + 56 + 35 + 39 + 46 + 47 + 34 + 37) / 13
Mean = 45.5
Therefore, on average, it takes approximately 45.5 minutes to fill a pallet.
2. To determine the relationship between the mean, median, and mode, we first need to find each value.
Mean = (13 + 16 + 12 + 11 + 8 + 14 + 12 + 18) / 8
Mean = 13.5
To find the median, we need to first order the numbers from least to greatest: 8, 11, 12, 12, 13, 14, 16, 18. Since there are an even number of values, we take the average of the two middle values to find the median.
Median = (12 + 13) / 2
Median = 12.5
The mode is the value that appears most frequently, which is 12.
Now we can compare the values:
Mean > median > mode
Therefore, the correct answer is: Mean > median > mode.
3. We know that the mean, median, and mode are all equal in this set of numbers. To find the missing value, we need to first find the current mean/median/mode.
Mean = Median = Mode
We can calculate the mean by adding all the values and dividing by the total number of values:
(7 + 6 + 10 + 13 + 7 + 2 + 5 + 6 + x) / 9 = (56 + x) / 9
Since we know that the mean/median/mode are all equal, we can set this expression equal to the missing value (x):
(56 + x) / 9 = x
Multiplying both sides by 9:
56 + x = 9x
Subtracting x from both sides:
56 = 8x
Dividing both sides by 8:
x = 7
Therefore, the missing value is x = 7.

Answers
The class with the greatest frequency is the class "15.2 - 19" with a frequency of 7. The class with the least frequency is the class "0 - 3.8" with a frequency of 2.
To construct a frequency distribution with 5 classes for the given data representing time spent reading a political blog in a day, we need to determine the class intervals and calculate the frequency, midpoint, relative frequency, and cumulative frequency.
First, we find the range of the data:
Range = Maximum value - Minimum value
Range = 19 - 0
Range = 19
To determine the class width, we divide the range by the desired number of classes:
Class width = Range / Number of classes
Class width = 19 / 5
Class width ≈ 3.8
Now, we can construct the frequency distribution table:
Class Frequency Midpoint R. Frequency C. Frequency
0 - 3.8 2 1.9 2/20 = 0.1 2
3.8 - 7.6 4 5.7 4/20 = 0.2 6
7.6 - 11.4 4 9.5 4/20 = 0.2 10
11.4 - 15.2 3 13.3 3/20 = 0.15 13
15.2 - 19 7 17.1 7/20 = 0.35 20
By organizing the data into classes and analyzing the frequencies, we can gain insights into the distribution of reading time and identify the most and least common time intervals spent on reading the political blog.

What is the exact value of tan(105°).
o 2+√3
o -2+√3
o 2-√3
o -2-3
Answers
Answer:
-2-√3.
Explanation:
\(tan(105)=tan(60+45)=\frac{tan60+tan45}{1-tan60*tan45}=\frac{\sqrt{3}+1}{1-\sqrt{3}}= \frac{(\sqrt{3}+1)^2}{(1-\sqrt{3})(1+\sqrt{3})}=-\frac{3+1+2\sqrt{3}}{2}=-2-\sqrt{3}.\)
The exact value of tan(105°) is -2+√3. Therefore, option (B) is correct.
What is tangent addition formula?To find the value, we can use the tangent addition formula:
tan(105°) = tan(60° + 45°)
tan(105°) = (tan 60° + tan 45°)/(1 - tan 60° * tan 45°)
Since tan(60°) = √3 and tan(45°) = 1, we can substitute these values into the formula:
tan(105°) = (√3 + 1)/(1 - √3)
To simplify the expression, we can multiply the numerator and denominator by the conjugate of the denominator, which is (1 + √3):
tan(105°) = [(√3 + 1)/(1 - √3)] * [(1 + √3)/(1 + √3)]
tan(105°) = [(√3 + 1)(1 + √3)]/[(1 - √3)(1 + √3)]
tan(105°) = (√3 + √3^2 + 1 + √3)/[(1 - √3^2)]
tan(105°) = (√3 + 4)/2
tan(105°) = (4 + √3)/2
tan(105°) = 2 + √3/2
tan(105°) = -2 + √3 (since 105° is in the second quadrant, where tangent is negative).
Therefore, the exact value of tan(105°) is -2+√3.
