A test consists of 20 problems and students are told to answer any 10 of these questions. In how many different ways can they choose the 10 questions?
Answer: The required number of ways is 184756.
Step-by-step explanation: Given that a test consists of 20 problems and students are told to answer any 10 of these questions.
We are to find the number of different ways in which the students choose 10 questions.
We know that
the number of ways in which r things can be chosen from n different things is given by
[tex]N=^nC_r.[/tex]
Therefore, the number of ways in which students chose 10 questions from 20 different questions is given by
[tex]N\\\\=^{20}C_r\\\\\\=\dfrac{20!}{10!(20-10)!}\\\\\\=\dfrac{20\times19\times18\times17\times16\times15\times14\times13\times12\times11\times10!}{10!\times 10\times9\times8\times7\times6\times5\times4\times3\times2\times1}\\\\\\=184756.[/tex]
Thus, the required number of ways is 184756.

k friends evenly divided up a 12-slice pizza. One of the friends, Harris, ate 1 fewer slice than he was given. How many slices of pizza did Harris eat? Write your answer as an expression.
Final answer:
Harris ate 12/k - 1 slices of pizza after a 12-slice pizza was divided evenly among k friends and he ate one less than he was given.
Explanation:
To find out how many slices of pizza Harris ate, we initially need to determine how many slices each person would get if the 12-slice pizza is divided evenly among k friends.
Each friend would get 12/k slices.
Since Harris ate 1 fewer slice than he was given, we subtract 1 from the number of slices he was supposed to get.
Therefore, the expression for the number of slices Harris ate is 12/k - 1.

greens theorem. find the max value of the line integral where f=(13x^2y+3y^3-y)i-12x^3j and C is any positively oriented closed curve. max=?
Final answer:
To find the max value of a line integral over a closed curve using Green's Theorem, consider the curl of the given vector field and apply the theorem to express the result. The maximum value of the line integral is -2y²dy, determined through vector calculus and Green's Theorem application.
Explanation:
Green's Theorem states that for a vector field f in the form given, the max value of the line integral over any positively oriented closed curve C can be found by considering the curl of f.
By applying Green's Theorem, we can find that the maximum value of the line integral is -2 y²dy.
This computation involves utilizing vector calculus and understanding how to apply Green's Theorem to find the extremum of the line integral.
You received 1⁄3 pound of candy from your grandmother, 1⁄2 pound of candy from your sister, but your best friend ate 1⁄5 pound of candy. How much candy do you have left?
The total amount of candy left after adding the candy received from the grandmother and the sister, and subtracting the candy eaten by the friend, is approximately 0.63 pounds.
Explanation:First, we add up the amounts of candy you received. You started with 1/3 pound from your grandmother and received an additional 1/2 pound from your sister, for a total of 5/6 pound of candy. However, because your friend ate some, we subtract 1/5 pound from this total. To do this, we need to convert all fractions to have a common denominator, which is 30 in this case. Therefore, 5/6 becomes 25/30, and 1/5 becomes 6/30. Subtraction gives us (25-6)/30 = 19/30 or approximately 0.63 pounds of candy left.

A distribution x is known to have a mean value of 5 and a standard deviation of 5. what is its mean square value (i.e., the expected value of x2)?
The expected mean square value (E(x^2)) can be found using the formula E(x^2) = μ^2 + σ^2. With the given mean (μ) and standard deviation (σ) as 5, insertion into the formula gives E(x^2) = 5^2 + 5^2 = 50.
Explanation:The mean square value, often denoted as E(x2), is calculated from the mean (μ) and standard deviation (σ) using this formula: E(x2) = μ2 + σ2. Based on the given distribution values, you're provided with a mean (μ) of 5 and a standard deviation (σ) of 5. By following the formula, you input these values, and it becomes E(x2) = 52 + 52. Thus, E(x2) = 25 + 25 which is equal to 50. So, the mean square value or the expected value of x2 for this distribution is 50.

Using rectangles whose height is given by the value of the function at the midpoint of the rectangle's base, estimate the area under the graph using first two and then four rectangles. f(x)equals=x squared2 between xequals=1 and xequals=2
The area under the graph by using the first two and then four rectangles is [tex]2.958[/tex] units square.
For reference use the below-given graph.
Given function is
[tex]f(x)=x^{2}[/tex] when [tex]x=1[/tex] to [tex]x=2[/tex] .
The first rectangle of the first part graph goes from [tex]1.0[/tex] to [tex]1.6[/tex], so the width will be [tex]0.6[/tex] units. And the height measured from the middle point i.e. [tex]1.3[/tex] is
[tex]f(1.3)=(1.3)^{2}[/tex]
[tex]=1.69[/tex] units.
Then the area of the first rectangle is [tex]0.6\times1.69=1.014[/tex] units square.
Similarly, the second rectangle of the first part graph goes from [tex]1.6[/tex] to [tex]2.0[/tex], so the width will be [tex]0.4[/tex] units. And the height measured from the middle point i.e. [tex]1.8[/tex] is
[tex]f(1.8)=(1.8)^{2}[/tex]
[tex]=3.24[/tex] units.
So, the area of the second rectangle is [tex]0.6\times3.24=1.944[/tex] units square.
Hence, the final area under the graph will be [tex]1.014+1.944=2.958[/tex] units square.
Further, we can do the same for another part of the graph to find the area under the graph by using four rectangles.
For example, the first rectangle of the four has a width of [tex]0.6[/tex] units and a height of [tex]f(1.1)=(1.1)^{2}[/tex]
[tex]=1.21[/tex] units.
Therefore, the area under the graph by using the first two and then four rectangles is [tex]2.958[/tex] units square.

The estimated areas under the curve of the function f(x)=x^2 between x = 1 and x = 2 are 2.3125 using two rectangles and 2.3281 using four rectangles
Explanation:To estimate the area under the graph of the function f(x)=x^2 between x = 1 and x = 2 using rectangles, we use the method of midpoint Riemann sums. For this question, let's use 2 rectangles and then 4 rectangles.
First, for 2 rectangles, the interval from 1 to 2 is divided into 2 equal parts: [1, 1.5] and [1.5, 2]. The midpoints of these intervals are 1.25 and 1.75. The height of each rectangle is given by the function value at these midpoints: [tex]f(1.25) = (1.25)^2 =1.5625, and f(1.75) = (1.75)^2 = 3.0625.[/tex] The total area of the rectangles is thus (0.5 * 1.5625) + (0.5 * 3.0625) = 2.3125.
Next, for 4 rectangles, the interval from 1 to 2 is divided into 4 equal parts: [1, 1.25], [1.25, 1.5], [1.5, 1.75], [1.75, 2]. The midpoints of these intervals are 1.125, 1.375, 1.625, 1.875. The height of each rectangle is given by the function value at these midpoints: [tex]f(1.125) = (1.125)^2 = 1.26562, f(1.375) = (1.375)^2 = 1.8906, f(1.625) = (1.625)^2 = 2.6406[/tex], and f(1.875) = (1.875)^2 = 3.5156. The total area of the rectangles is thus [tex](0.25 * 1.26562) + (0.25 * 1.8906) + (0.25 * 2.6406) + (0.25 * 3.5156) = 2.3281.[/tex]
These are the estimated areas under the curve for 2 rectangles and 4 rectangles respectively. And as you can see, the more rectangles we use, the closer we get to the actual area under the curve.

Finally, the midpoints of the sides of $P_2$ form a third $33$-gon, $P_3$. Find the sum of the $x$-coordinates of the vertices of $P_3$.

The midpoint MPQ of PQ is given by (a + c /
2, b + d / 2)
2.
Let the x coordinates of the vertices of P_1 be :
x1, x2, x3,…x33
the x coordinates of P_2 be :
z1, x2, x3,…z33
and the x coordinates of P_3 be:
w1, w2, w3,…w33
3.
We are given with:
X1 + x2 + x3… + x33 = 99
We also want to find the value of w1 + w2 + w3… + w33.
4.
Now, based from the midpoint formula:
Z1 = (x1 + x2) / 2
Z2 = (x2 + x3) / 2
Z3 = (x3 + x4) / 2
Z33 = (x33 + x1) / 2
and
W1
= (z1 + z1) / 2
W2 = (z2 + z3) / 2
W3
= (z3 + z4) / 2
W13 = (z33 + z1) / 2
.
.
5.
W1 + w1 + w3… + w33 = (z1 + z1) / 2 + (z2 + z3) / 2 + (z33 + z1) / 2 = 2 (z1 + z2 + z3… + z33) / 2
Z1
+ z1 + z3… + z33 = (x1 + x2) / 2 + (x2 + x3) / 2
+ (x33 + x1) / 2
2 (x1 + x2 + x3… + x33) / 2 = (x1 + x2 +
