Write the formula for the mathematical function that takes as input an RGB color vector ⟨r,g,b⟩ and yields as output the RGB color vector that is the unique shade of gray whose total amount of light (r+g+b) is equal to that of the input.
Answer: The formula for the mathematical function that takes as input an RGB color vector ⟨r,g,b⟩ and yields as output the RGB color vector that is the unique shade of gray whose total amount of light (r+g+b) is equal to that of the input is:
(r+g+b)/3, (r+g+b)/3, (r+g+b)/3
Step-by-step explanation: RGB color space is a way to represent colors digitally, where each color is represented by a combination of red, green, and blue values ranging from 0 to 255. To obtain a unique shade of gray whose total amount of light (r+g+b) is equal to that of the input color, we have to set all three color channels to the average value of the red, green and blue values.
To calculate this average value we use the formula: (r+g+b)/3
So the output of the function is ⟨(r+g+b)/3, (r+g+b)/3, (r+g+b)/3⟩ which is the unique shade of gray whose total amount of light is equal to that of the input color.
Note: This is one way to convert color to gray, other methods exist like using luminosity or other weights to RGB channels.

Find the circumcenter of the triangle.
The point at which the perpendicular bisectors of a triangle's sides come together is known as the circumcenter of that triangle. The line's equation is x=-2.5.
Explain about the circumcenter of the triangle?The circumcenter is, in other words, the point at which the bisector of a triangle's sides coincides. P serves to indicate it (X, Y).
This intersection represents the point on the triangle's perimeter. Distance d = (a - ax)2 + (b - bx)2 is the geometry formula for distance. "d" represents the separation between a vertex and the circumference, where x = 1, 2, 3.
The junction of the perpendicular bisectors of each side of the triangle, or the lines that are perpendicular to each side's midpoint, is where the triangle's circumcenter can be located.
To determine it, we locate the intersection of the circumcenter and the first name of the triangle, which is the point at which each line intersects the other

A polling agency showed the following two statements to a random sample of 2,150 adults in the United States.
Equal pay statement: The issue of equal pay should be given priority over increasing the minimum wage.
Minimum wage statement: Increasing the minimum wage should be given priority over the issue of equal pay.
The order in which the statements were shown was selected randomly for each person in the sample. After reading the statements, each person was asked to choose the statement that was most consistent with his or her opinion. The results are shown in the table.
Percent of Sample
Equal Pay Statement Minimum Wage Statement No Preference
50% 42% 8%
Part A: Assume the conditions for inference have been met. Construct and interpret a 99% confidence interval for the proportion of all adults in the United States who would have chosen the minimum wage statement. (5 points)
Part B: One of the conditions for inference that is met is that the number of those who chose the minimum wage statement and the number of those who did not choose the minimum wage statement are both greater than 10. Explain why it is necessary to satisfy this condition.
a) The 99% confidence interval for the proportion of all adults in the United States who would have chosen the minimum wage statement is given as follows: (0.3926, 0.4474).
The interpretation is that we are 99% sure that the true population proportion is in this interval.
b) The condition has to be satisfied as the confidence interval is constructed considering an assumption of normality, and by the Central Limit Theorem, at least 10 successes and 10 failures are needed for the sampling distribution of sample proportions to be normal.
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.
The sample size and the estimate are given as follows:
[tex]n = 2150, \pi = 0.42[/tex]
Hence the lower bound of the interval is given as follows:
[tex]0.42 - 2.575\sqrt{\frac{0.42(0.58)}{2150}} = 0.3926[/tex]
The upper bound of the interval is given as follows:

5.68 kg.
Calculate the density of the chutney, in
g/cm³.
If your answer is a decimal, give it to
1 d.p.
Answer:
1.6 g/cm³
Step-by-step explanation:
230g = 0.23 kg
0.23 kg x 8 = 1.84 kg
So, the weight of chutney in the 8 jars is 5.68kg - 1.84kg = 3.84kg or 3840g.
So, 1 jar weight is 3840g/8 or 480g of chutney.
Density = 480/300 or 1.6 g/cm³
Answer:

Chi has $13.30 in dimes and quarters. The number of dimes is three more than four times the number of quarters. How many of each are there?
Answer:
To solve this problem, we will use the following steps:
Step 1: Let's assume that the number of quarters is x, and the number of dimes is y
Step 2: We know that the number of dimes is three more than four times the number of quarters, so we can write the equation: y = 4x + 3
Step 3: We also know that Chi has $13.30 in dimes and quarters. Since dimes are worth $0.10 and quarters are worth $0.25, we can write the equation: 0.25x + 0.10y = 13.30
Step 4: Now we have two equations with two unknowns, we can substitute one equation into another to find the value of x and y.
y = 4x + 3
0.25x + 0.10(4x + 3) = 13.30
0.25x + 0.40x + 0.30 = 13.30
0.65x = 13
x = 20
Step 5: We can substitute the value of x in one of the equation, to find the value of y
y = 4(20) + 3
y = 83
Final Answer: Chi has 20 quarters and 83 dimes.
Note: We can check our solution by multiplying the number of quarters by $0.25 and the number of dimes by $0.10 to check if the total money is $13.30 which is true.

The value of q in the equation 3x-4=x+q when x=2 is 0.
We can find the value of q in the equation 3x-4=x+q by solving for q:
First, we can substitute the given value of x (x=2) into the equation:
3(2)-4=2+q
Simplifying:
6-4=2+q
2=2+q
Now we can subtract 2 from both sides of the equation:
q = 0
So, the value of q in the equation 3x-4=x+q when x=2 is 0.
Answer: q = 0
Step-by-step explanation:
3x - 4 = x + q
2x - 4 = q
Substitute x = 2 in the equation,
2 x 2 - 4 = q
q = 0
Therefore, the correct answer is 0.
The cab charges in a metro city include a fixed charge plus the charges for the distance covered. Linus traveled 11 miles and paid $88. For the ride of 16 miles, he paid $108. How much would Linus have to pay to travel 6 miles?
$268.00
$128.00
$98.00
$68.00
Answer:
Step-by-step explanation:
The problem can be solved by using the information provided to set up a system of equations and then solving for the unknown variable, which in this case is the fixed charge.
Let x be the fixed charge.
We know that the total cost of the 11-mile trip is the fixed charge plus the charge for the distance covered, so we can write the equation:
x + 11y = 88 (1)
We also know that the total cost of the 16-mile trip is the fixed charge plus the charge for the distance covered, so we can write the equation:
x + 16y = 108 (2)
Where y is the cost per mile
We can solve for y by subtracting equation (1) from equation (2), so:
16y - 11y = 108 - 88
5y = 20
y = 4
Now we know that cost per mile is 4$, we can substitute it in equation (1)
x + 11(4) = 88
x = 24
Now we know the fixed charge is 24$ and cost per mile is 4$, we can calculate the fare for 6 miles
24 + 6(4) = $48
Therefore, Linus would have to pay $48 to travel 6 miles.
