The hypergeometric distribution should not be used, hence the correct option is given by:
no, because it is not looking for the first occurrence of success.
When the hypergeometric distribution should be used?These two conditions should be respected:
We should be looking for the probability of x successes on n trials, not the number of trials until n successes.The trials should not be independent, that is, the probabilities on each trial should be different.None of these conditions are true in this case, hence the correct option is given by:
no, because it is not looking for the first occurrence of success.

Answer: The answer is C.
Step-by-step explanation:
Simplify the radical by breaking the radicals up into a product of known factors, assuming real numbers.
Reflect (-1, 4) over the x-axis.
Then translate the result up 3 units.
What are the coordinates of the final point?
If a point (-1, 4) reflected over the x-axis then translate the result up 3 units then the coordinates of the final point are (-1, -1)
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
Reflecting a point over the x-axis negates the y-coordinate, while leaving the x-coordinate unchanged.
Therefore, reflecting (-1,4) over the x-axis gives us the point (-1,-4).
Translating a point up 3 units means adding 3 to the y-coordinate. Therefore, translating (-1,-4) up 3 units gives us the point:
(-1, -4 + 3) = (-1, -1)
So the final point is (-1,-1).
Hence, if a point (-1, 4) reflected over the x-axis then translate the result up 3 units then the coordinates of the final point are (-1, -1)

The volume of a right cone is 41251 unit. If its diameter measures 30 units, find its
height.
Volume is a three-dimensional scalar quantity. The height of the cone is 175.075 units.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the right cone is 41,251 unit³, while the diameter of the cone is 30 units. Therefore, the radius of the cone is 15 units. Thus, the height of the cone will be,
Volume = (1/3)×π×r²×h
41,251 = (1/3)×π×(15²)×h
h = 175.075 units
Hence, the height of the cone is 175.075 units.

The amount in the account after the given time if compounded semiannually to the nearest cent is $1104.2
Compound interestInterest is any amount added on a sum of money over a period of time. The formula for calculating the compound interest is:
A = P(1+r/n)^nt
Given
Principal = $1000
rate r = 5% = 0.05
time = 3years
n = 2 (semi annually)
Substitute the given parameters
A = 1000(1 + 0.05/3)^3(2)
A= 1000(1.1042)

The 24 boxes which will fit into the large box if the box is in the shape of a rectangular prism.
What is a cuboid?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape.
We can find the volume of the box = length×width×height
Volume for the large box = 12×10×12 = 1440 cubic in
Volume for the small box = 4×5×3 = 60 cubic in
Number of cookie boxes will fit into the large box = 1440/60 = 24

An architect-designed an attic space in the shape of a square pyramid. After reviewing the design, he decided to make a second design for an attic space in the shape of an oblique pyramid. He created models of both designs as shown.
Both models were cut horizontally at the same height, finding the cross-sections with the same area. Several other horizontal cross-sections were analyzed and found to have the same area. Both pyramid models also have the same height, a.
Which formula would allow the architect to calculate the volume of his second attic space design?
A.V=s^2a
B.V=1/2s2b
C.V=1/3scb
D.V=1/3s2a
The formula that would allow the architect to calculate the volume of his second attic space design is V = 1/3s²b. Option D is correct.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
The formula for the volume of an oblique pyramid is V = 1/3 * base area * height. In this case, the base of the oblique pyramid is the shape of the cross-section, which is a square. So, the formula becomes V = 1/3 * s^2 * height. The given information states that the height is "a", which is the same for both pyramid models.
Therefore, the formula for calculating the volume of the second attic space design becomes V = 1/3 * s² * a.

Step-by-step explanation:
Architecture is a five-year degree that requires a keen interest in the topic. A five-year undergraduate architecture degree, known as a B. Arch., or a two- or three-year post-college master's program, known as an M. Arch., are the two alternatives for those who wish to get an architectural degree that will help them get licensed as an architect. You'll have to labor every day and night. Of course, your performance in class will have an impact. Some instructors may offer homework that are beyond your grasp and abilities. Everything you do must be carefully thought out, imagined, and built.

Step-by-step explanation:
For shipping container:
l = 240 in, w 84 in, h = 120 in
[tex]V_{shipping\: container}=lwh[/tex]
[tex]\implies V_{shipping\: container}=240\times 84\times 120[/tex]
[tex]\implies V_{shipping\: container}=2,419,200\:in^3[/tex]
For box:
l = 10 in, w = 5 in, h = 12 in
[tex]V_{box}=lwh[/tex]
[tex]\implies V_{box}=10\times 5\times 12[/tex]
[tex]\implies V_{box}=600\:in^3[/tex]
[tex]\frac{V_{shipping\: container}}{V_{box}}=\frac{2,419,200}{600}[/tex]
[tex]\frac{V_{shipping\: container}}{V_{box}}=4032[/tex]
Surface area of box
