The value of the evaluated iterated integral is 6.667.
As per the given data the iterated integral is [tex]$\int_2^3 \int_0^2 x y^2 d x d y$[/tex]
Here we have to evaluate the given iterated integral to find the value of [tex]$\int_2^3 \int_0^2 x y^2 d x d y$[/tex] .
The definite integral of a real-valued function f(x) with respect to a real variable x on an interval (a, b) is expressed as
[tex]$\int_a^b f(x) d x=\mathrm{F}(\mathrm{b})-\mathrm{F}(\mathrm{a})$[/tex]
Here,
[tex]$\int=$[/tex] Integration symbol
a - Lower limit
b - Upper limit
f(x) - Integrand
dx - Integrating agent
Thus, [tex]$\int a b f(x) d x$[/tex] is read as the definite integral of f(x) with respect to dx from a to b.
Indefinite integrals are implemented when the boundaries of the integrand are not specified.
[tex]& \int_2^3 \int_0^2 x y^2 d x d y \\[/tex]
Integrate the given iterated integral.
We get:
[tex]& \int_2^3 x d x \int_0^2 y^2 d y \\[/tex]
[tex]& =\int_2^3 x d x\left(\left.\frac{y^3}{3} \right|_0 ^2\right) \\[/tex]
Substitute the limits in y.
[tex]& =\int_2^3 \frac{8}{3} x d x \\[/tex]
[tex]& =\left.\frac{8}{3\times2} x^2\right|_2 ^3 \\[/tex]
[tex]& =\left.\frac{4}{3} x^2\right|_2 ^3 \\[/tex]
Substitute the limits in x.
[tex]& =\frac{4}{3} \times 9-\frac{4}{3} \times 4 \\[/tex]
[tex]& =\frac{20}{3}[/tex]
= 6.667.
Therefore answer is 6.667.

Samples of size 60 are drawn from a large population known to have a mean of 78 and a standard deviation of 12. What proportion of these samples would we expect to have a mean greater than 80?
a
0.566
b
0.098
c
Almost none
d
0.434
e
0.901
Answer: 0.098
Step-by-step explanation: First you’ll need to find the sample distribution mean and standard deviation (which is 78 and 1.55). Then you plug it into calculator using normal approximation cause n is large: normalcdf(80,100,78,1.55)
As, 0.098 proportion of these samples would, we expect to have a mean greater than 80. Thus, option (C) is correct.
What is the population?As the population is defined, as a group of groupings with a common characteristic. In data point, a population is the pool of individuals from which a statistical sample is drawn for a study. As we see, different countries have different populations.
As here the μ = 78, σ = 1.5492 and x = 80
We need to compute P(X >= 80). The corresponding z-value is calculated using Central Limit Theorem
z = (x - μ)/σ
z = (80 - 78)/1.5492 = 1.29
Therefore,
P(X >= 80) = P(z <= (80 - 78)/1.5492)
= P(z >= 1.29)
= 1 - 0.902 = 0.098
Therefore, The right option (B) is correct

12. the number of errors in a textbook follows a poisson distribution with a mean of 0.04 errors per page. what is the expected number of errors in a textbook that has 204 pages? circle one answer.
The number of errors in a textbook follows a Poisson distribution with a mean of 0.04 errors per page. To find the expected number of errors in a textbook with 204 pages, we need to multiply the mean by the number of pages.
Expected number of errors = mean * number of pages = 0.04 * 204 = 8.16
Therefore, we can expect to find approximately 8 errors in a textbook that has 204 pages, based on the given Poisson distribution with a mean of 0.04 errors per page. It is important to note that this is only an expected value and the actual number of errors could vary.
Additionally, Poisson distribution assumes that the errors occur independently and at a constant rate, which may not always be the case in reality. Nonetheless, the Poisson distribution provides a useful approximation for the expected number of rare events occurring in a given interval.

Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
Answer:
Step-by-step explanation:
Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
THIS IS THE COMPLETE QUESTION BELOW;
1. Explain how you calculate the net force in any direction on the box.
2. Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
3. What force could be applied to the box to make the net force in the horizontal direction zero? Explain.
4. Suppose a force of 25 N to the right is added to the box. What will be the net force to the right?
CHECK THE ATTACHMENT FOR THE FIQURE.
1)since the given horizontal forces are acting on the box at opposite direction then
NET FORCE= (100- 50)N
= 50N( this is because the 100N and 50N acting Horizontally will cancel each other, then the remaining force is 50N.
✓Since, the two vertical forces also acted on the box in opposite direction, then
NET FORCE= (25 25)N
= 0N
Note: horizontal forces are one acting from right to left and vice versa, while vertical forces are ones acting from up to down and vice versa.
HENCE, NET FORCE = 50N + 0N= 50N
2) since the net vertical force was 0N, if
15N force is added then we still have NET FORCE OF 15N
3) if force of 50N is applied to horizontal forces moving from left to right then NET HORIZONTAL FORCES= 0N
4) since, the net force for the box is 50N, if Horizontal force of 25N is added moving left to right then NET FORCE = 25N for whole box.

Answer:
A) Triangle PQR
Step-by-step explanation:
This is the correct triangle because it has the exact same measurements as Triangle ABC. Angles A and P are the same angle on the triangles and they have the same measure (70). Angles C and R are the same angle on the triangles and they have the same measure (75). To solve for Angle C in Triangle ABC though, add angles 70 + 35 together to get 105. A triangle has a total measure of 180, so subtract 180 - 105 to get 75.

Consider the following integral. Sketch its region of integration in the xy-plane.
∫1_0∫y_(√y) 110x2y3dxdy
(a) Which graph shows the region of integration in the xy-plane? ? A B
(b) Evaluate the integral.
a. The region of integration is the region between the curves[tex]y = x^4[/tex]and [tex]y = x^2[/tex], for 0 ≤ y ≤ 1.
b. The value of the integral is -0.6875.
To sketch the region of integration, we need to find the boundaries of the integral.
We are integrating with respect to x first, so we need to express the limits of integration for x in terms of y.
From the inner integral, we have:
y ≤ [tex]x^2[/tex] ≤ √y
Taking the square root of both sides of the right inequality, we get:
[tex]y^{1/4}[/tex] ≤ x ≤ √y
Thus, the region of integration is the region between the curves[tex]y = x^4[/tex]and [tex]y = x^2[/tex], for 0 ≤ y ≤ 1.
To sketch the region, we can first draw the curves [tex]y = x^4[/tex] and [tex]y = x^2,[/tex]as shown in graph (A) below:

The region of integration is the shaded region between the curves, as shown in graph (B) below:

To evaluate the integral, we can use the boundaries we found and evaluate the integral using the following steps:
[tex]\int 1_0 \int y_(\sqrt{y } ) 110x^2y^3dxdy[/tex]
[tex]= \int 0^1 \int x^{1/2}^x^2 110x^2y^3 dy dx[/tex] (using the limits we found earlier)
[tex]= \int 0^1 110x^2 [(1/4)y^4]_(x^{1/2})^{x^2} dx[/tex] (integrating with respect to y)
[tex]= \int 0^1 110x^2 [(1/4)x^8 - (1/4)x^4] dx[/tex] (substituting the limits of integration)
[tex]= \int 0^1 (27.5x^10 - 27.5x^6) dx[/tex].
[tex]= [2.75x^11 - 3.4375x^7]_0^1[/tex](integrating and substituting limits)

The volume of a box is 231 cubic inches. The width is 7 inches. The length is 8 inches more than the height. Find the missing dimensions.
Answer:The missing dimensions are now
width =7inches
length = 11 inches
Height = 3 inches
Step-by-step explanation:
Volume of a box is given as =width x length x height 231 in^3
Given
width = 7 inches
height =represented as h
l = 8 inches more than the height= 8+h
V = w x l x h
231 = 7(8+h)(h)
231=( h² + 8h)7
231/ 7= h²+8h
33= h²+8h
Giving us the quadratic equation
h² + 8h - 33 = 0
=(h-3)(h+11) = 0
h-3= 0
h= 3 also h+11=0, h=-11
h= 3 or -11
Since the value of height cannot have a negative value,
h = 3inch
l = 8+h = 8+3 = 11 in
The missing dimensions are now
width =7inches
length = 11 inches
Height = 3 inches
State if the triangles are similar. If so, state how you know they are.
Answer:
The triangles are similar
Step-by-step explanation:
Since EF ║ UT, m∠FUT = m∠EFU because alternate interior angles are congruent when lines are parallel.
m∠UDT = m∠EDF because vertical angles are congruetnt
Therefore ΔUDF is similar to ΔFDE because if two angles of a triangle are congruent to two angles of another triangle, then the triangles are similar.

let a be an n x n matrix with an eigenvalue of multiplicity n. show that a is diagonalizable if and only if a = i
An n x n matrix a with an eigenvalue of multiplicity n is diagonalizable if and only if a = i, where i is the identity matrix.
Suppose a is diagonalizable. Then there exists an invertible matrix P such that a = PDP^(-1), where D is a diagonal matrix. Since a has an eigenvalue of multiplicity n, the diagonal entries of D are all equal to that eigenvalue. Therefore, a = PDP^(-1) = P(lambda I)P^(-1) for some scalar lambda. But since the eigenvalue has multiplicity n, lambda must equal the eigenvalue, which implies that D = lambda I. Therefore, a = [tex]P(lambda I)P^(-1) = PDP^(-1)[/tex] = P(lambda I)P^(-1) = lambda PPP^(-1) = lambda I. Thus, a = lambda I, and since the eigenvalue has multiplicity n, we have lambda = 1. Therefore, a = i.
Conversely, suppose a = i. Then a is trivially diagonalizable, since any matrix is diagonalizable if and only if it is already diagonal. Therefore, a is diagonalizable, and the proof is complete.

A cookie jar starts off with 32 cookies in it, and
each day 2 cookies are eaten. After a certain
number of days, there are 14 cookies left in the jar.
Which of the following equations represents the
day, d, when there are 14 cookies in the jar?
Answer:
9 days
Step-by-step explanation:
32-2-2-2-2-2-2-2-2-2 = 14
The equation that represents the day, d, when there are 14 cookies in the jar will be 14 = 32 - 2d, and that day will be on the 9th day.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given,
Initial cookie = 32
Since each day 2 cookies are eaten so after "d" days the total eaten cookies will be 2d.
Remaining cookies = initial cookies - eaten cookies
Remaining cookies = 32 - 2d
The day when 14 cookies remain will be,
14 = 32 - 2d
2d = 32 - 14
d = 9
Hence "The equation that represents the day, d, when there are 14 cookies in the jar will be 14 = 32 - 2d, and that day will be on the 9th day".
