2.833 10 6 is the largest error as a result.
What is differentiation?Finding a function's derivative, or rate of change, is the process of differentiation in mathematics.
The practical approach of differentiation can be performed utilizing only algebraic operations, three fundamental derivatives, four principles of operation, and an understanding of how to manipulate functions, in contrast to the theory's abstract character.
The three fundamental derivatives (D) are: (1) D(xn) = nxn 1 for algebraic functions, where n is any real number; (2) D(sin x) = cos x and D(cos x) = sin x for trigonometric functions; and (3) D(ex) = ex for exponential functions.
Hence, 2.833 10 6 is the largest error as a result.

The likelihood that a random cumulative variable will fall within a specific range of values rather than taking on a single value is specified by the Probability Density Function.
The probability density function (PDF), also known as the density of a continuous random variable, is a function whose value at any specific sample (or point) in the data point (the range of potential values for the random variable) can be understood as having given a relative likelihood that the value of something similar to the random variable would be closer to that sample.
There is no absolute probability that a random variable will take on any specific value because there are an unlimited number of alternative values to begin with. However, the PDF value at two samples can be used to estimate how much more likely it is for the random variable to have that particular value in any given draw.
The Cantor distribution, which although having no discrete component, does not assign positive probabilities to any specific locations, and discrete random variable probability distributions do not all have a density function.
A distribution has a density function if and only if the cumulative distribution function F(x) is fully continuous. In this case, F is typically always differentiable, and its derivative can be used to symbolize the probability density.

In the given question, Bart is required to pass out 80 flyers for an upcoming event. He passes out an average of 10 flyers per minute.
The situation can be represented using the function f(x)=80-10x
where x represents time in minutes.
We have to create a graph of the situation.
To create the graph we firstly find the value of f(x) for x=0,1,2,3,..............
The given function is f(x) = 80-10x
Now put x = 0
So f(0) = 80-10(0)
f(0) = 80-0
f(0) = 80
Now put x = 1
So f(1) = 80-10(1)
f(1) = 80-10
f(1) = 70
Now put x = 2
So f(2) = 80-10(2)
f(2) = 80-20
f(2) = 60
Now put x = 3
So f(3) = 80-10(3)
f(3) = 80-30
f(3) = 50
Now put x = 4
So f(4) = 80-10(4)
f(4) = 80-40
f(4) = 40
Now the table is
x 0 1 2 3 4
f(x) 80 70 60 50 40

A bag contains 100 marbles which are red, green, and blue. suppose a student randomly selects a marble without looking, record's the color,and then places the marble back in the bag the student has recorded 7 red marbles, 2 green marbles and 11 blue marbles. predict how many green marbles are in the bag
Answer: 10 marbles
Step-by-step explanation:
First, arrange all the numbers of marbles that the student picked in a ratio
red:green:blue
7:2:11
When adding all the coloured marbles that the student picked together, you get 20 marbles or "parts" as you would usually say in ratio.
Then, it would be helpful to rewrite the ratios as fractions, with 20 as the denominator:
[tex]\frac{7}{20}:\frac{2}{20}:\frac{11}{20}[/tex]
However, the bag contains 100 marbles so we should have 100 as the denominator instead of 20. 20 is a fifth of 100, so in this case, we would multiply everything (the numerator and the denominator) by 5:
[tex]\frac{7*5}{20*5} :\frac{2*5}{20*5} :\frac{11*5}{20*5}[/tex]
[tex]\frac{35}{100}:\frac{10}{100}:\frac{55}{100}[/tex]
Therefore, you could predict you would get 35 red marbles, 10 green marbles, and 55 blue marbles.

Bob bought a sofa on sale for $134.40. This price was 68% less than the original price. What was the original price?
Answer:
$420
Step-by-step explanation:
To find the original price, we need to determine how much the sale price was discounted, and then add that amount back to the sale price. Since the sale price was 68% less than the original price, the discount was 100% - 68% = 32% of the original price.
To find the amount of the discount, we multiply the original price by the discount percentage: 32% * original price = $134.40
Dividing both sides of the equation by the discount percentage gives us the original price: original price = $134.40 / (32% * 1) = $134.40 / 32% = $420.
Therefore, the original price of the sofa was $420.

c) For the high jump, each competitor receives multiple opportunities to clear the bar at each height. On average, Shane completes 3 out of 3 jumps on the lowest bar, 5 out of 6 jumps on the middle bar, and 3 out of 4 jumps on the highest bar. What is
Shane’s overall average number of jumps completed? (2 points)
d) If Shane’s average number of jumps completed is greater than one-half, then the eighth graders earn 50 points. Which grade should be awarded 50 points**? (1 point)
Answer:
c) To find Shane's overall average number of jumps completed, we need to add up the total number of jumps he completed at each height and divide by the total number of jumps he attempted.
At the lowest height, Shane completed 3 out of 3 jumps, for a total of 3 completed jumps.
At the middle height, Shane completed 5 out of 6 jumps, for a total of 5 completed jumps.
At the highest height, Shane completed 3 out of 4 jumps, for a total of 3 completed jumps.
In total, Shane completed 3 + 5 + 3 = 11 jumps out of a total of 3 + 6 + 4 = 13 jumps attempted.
His overall average number of jumps completed is 11 / 13, or approximately 0.85 jumps.
d) Since Shane's average number of jumps completed is greater than one-half (0.5), the eighth graders should be awarded 50 points
Step-by-step explanation:
For your other question A and B for A Correct! To find the total distance thrown by Claire and Grace, you first converted the mixed numbers 5/8 and 3/5 to fractions with a common denominator (in this case, 40), then added those fractions together to find the total distance in fraction form. Finally, you converted the fraction 49/40 back to a mixed number and added it to the whole number distances thrown by Claire and Grace to find their total distance.
The total distance thrown by Claire and Grace is 82 feet 9/40 inches, or approximately 82.225 feet. For B also Correct! Since the total distance thrown by Claire and Grace is not greater than 83.7 feet, the eighth graders should be awarded 50 points.

trip to Wild Rivers cost $23.50. Write an equation
and solve to find the number of miles (m) the Lift
driver had to drive Tyler.
Answer:
23.50=1.50x+4, m=13
Step-by-step explanation:
The $4 is a constant, no matter how many times the app is used, the $4 amount will stay. The $1.50 is dependant on how many times the action is preformed so it has to be put with M. Overall, the cost is 23.50 which is why the entire equation is equal to $23.50.
Subtract 4 from the 23.50, then divide that result with 1.50

Finding the expected difference of deviation from the actual number is what is meant by variance. As a result, variance is influenced by the data set's standard deviation.
Data is more dispersed from its mean the higher the variance value, and less dispersed from mean if the variance value is low or minimal. As a result, it is referred to as a measure of data spread from mean.

The answer is the range of the function y = x + 3 when the domain is {-2, 0, 4}, which is the set {1, 3, 7}.
Step-by-step explanation:
The range of the function y = x + 3 is the set of all possible values of y for a given value of x in the domain of the function. In this case, the domain of the function is the set {-2, 0, 4}, so the range of the function is the set of all possible values of y for x equal to -2, 0, and 4.
To find the range, we need to substitute each of these values of x into the equation y = x + 3 and solve for y. When x = -2, we have y = -2 + 3 = 1. When x = 0, we have y = 0 + 3 = 3. And when x = 4, we have y = 4 + 3 = 7. Therefore, the range of the function y = x + 3 when the domain is {-2, 0, 4} is the set {1, 3, 7}.
Use Green's Theorem to calculate the work done by the force F on a particle that is moving counterclockwise around the closed path C.F(x,y) = (e^x -3 y)i + (e^y + 6x)jC: r = 2 cos thetaThe answer is 9 pi.
the work done by the force F on a particle moving counterclockwise around the closed path C is 9π by integral.
Green's Theorem states that:
∮C F · dr = ∫∫D (∂Q/∂x - ∂P/∂y) dA
Where C is the boundary of the region D, P and Q are the components of the vector field F, and dr is the vector differential along the boundary C.
In this case, the region D is a circle with radius 2, so we can express the boundary C as r = 2 cos θ. We also need to calculate the components of the vector field F. These are P = e^x - 3y and Q = e^y + 6x.
Plugging these values into Green's Theorem, we get integral:
∮C F · dr = ∫∫D (∂Q/∂x - ∂P/∂y) dA
= ∫∫D (e^y + 6 - (-3)) dA
= ∫∫D (e^y + 9) dA
= ∫ 0 2π ∫ 0 2 (e^2 cosθ
+ 9) (2 dθ)
= 4π ∫ 0 2 (e^2 cosθ + 9) dθ
= 9π
Therefore, the work done by the force F on a particle moving counterclockwise around the closed path C is 9π.
