A farmer must transport a fox, goose and bag of beans from one side of a river to
another using a boat which can only hold one item in addition to the farmer, subject to
the constraints that the fox cannot be left alone with the goose, and the goose cannot
be left alone with the beans. What is the fewest number of trips the farmer has to take
in order to transport all three safely to the other side of the river?

Answers
Answer:
The man in the goose cross the river, with the fox and the beans together, he leaves the goose on the other side and goes back across.
The man then takes the fox across the river, and since he can’t leave the fox in the goose together, he brings that goose back.
Again, since the goose and the beans can’t be left together, he leaves the goose and he takes the beans across and leaves with the fox.
He returns to pick up the goose and heads back across the river one last time.

You are throwing a party, and you need 555 liters of Yoda Soda for every 121212 guests.
If you have 363636 guests, how many liters of Yoda Soda do you need?
liters
Answers
Answer:
15 litres
Step-by-step explanation:
Given
5 litres = 12 guests
Required
Determine the number of litres for 36 guests
Represent the required number of litres with L.
So, we have the following relationship:
[tex]5\ litres = 12\ guests[/tex]
[tex]L = 36\ guests[/tex]
Cross Multiply
[tex]L * 12\ guests = 5\ litres * 36\ guests[/tex]
[tex]L * 12= 5\ litres * 36[/tex]
[tex]12L = 180\ litres[/tex]
Solve for L
[tex]L = \frac{180\ litres}{12}[/tex]
[tex]L =15\ litres[/tex]
Hence, 15 litres are needed

Answers
Problem 1
Answers:
Cone: TriangleCylinder: RectangleSphere: Circle------------------------
Explanation:
Imagine a fan blade rotating. As it rotates really quickly, it occupies a 3D space. Or perhaps imagining rotating eggbeaters is a better thing to have in mind. Those blades spin really fast to form a 3D shape. So that's what's going on with this problem. If you spin a triangle around an axis, a cone will form. The base of the triangle forms the base of the cone. Half the base of the triangle is the radius of the cone. The height of the triangle is the height of the cone.
Similarly, a rectangle rotated around its center axis forms a cylinder. Think of a revolving door. That's often a classic example. Finally, a circle spun around any of its diameters will form a sphere.
========================================================
Problem 2
Answers:
Object 1: Cup = CylinderObject 2: Ball = SphereObject 3: Funnel = ConeObject 4: Paper towel roll = Cylinder-------------------------------
Explanation:
Pick objects around your house that are fairly simple in design and resemble either a cylinder, sphere, or cone. A cup resembles a cylinder just it doesn't have a top to it. A ball is a 3D sphere that has an interior to it, unless the ball is filled with air. A funnel resembles a cone due to its triangular shape of sorts. A paper towel roll (the card board piece or the cardboard plus the actual paper towels) resemble a cylinder as well. You can pick any four other objects you have around your house such as a cylindrical speaker, batteries (shaped as a cylinder), soup cans (also cylinders), and so on.
========================================================
Problem 3
Answers:
a) volume of cylinder = pi*r^2*hb) volume of sphere = (4/3)*pi*r^3c) volume of pyramid = (1/3)*L*W*Hd) volume of cone = (1/3)*pi*r^2*h-------------------------------
Explanation:
These formulas are what you should memorize or have handy on a flashcard. It is possible to derive them, but it would require calculus to do so. Also, such a process is quite length. So memorization or flashcards are the better way to go.
For the cylinder and cone, r is the radius and h is the height. Note how the formulas are nearly identical except the cone has the (1/3) term. This shows that the cone's volume is 1/3 that of the cylinder's volume where they both have the same radius r and height h.
The sphere also deals with the radius r, but we don't have to worry about the height of the sphere (it's really just 2r).
For the pyramid, L,W,H represent the length width and height respectively. The length and width form the base of the pyramid. Recall that L*W*H is the volume of a rectangular block. The volume of a pyramid is 1/3 of that rectangular block's volume.
If all of a 2D object's sides and angles have different lengths, such shape is said to be irregular.
What is 2D shape?In geometry, a form or figure having length and breadth is referred to as a "2D shape." Due to the lack of a thickness, a third dimension, such as the case of a prism or a cube, two-dimensional or 2D objects are often measured in terms of their two faces.
'2D' refers for 2-dimensional. A 2D shape is any form that has two dimensions. Consider for a moment what it means to have two dimensions. We could only move backwards or forwards in a straight line if we only had one dimension to work with. One dimension is a line.
Cone: Triangle
Cylinder: Rectangle
Sphere: Circle
Therefore, if all of a 2D object's sides and angles have different lengths, such shape is said to be irregular.

A restaurant chain with multiple branches would like to measure the effectiveness of a customer skills training program for its employees. A random sample of 30 branches is chosen, and the daily sales for these branches are recorded. All the employees at these branches then undergo a customer skills training program, and shortly thereafter the daily sales at these 30 branches are again recorded. (a) Which type of test should the company use to determine if the customer skills program helped increase sales? a. One sample t-test b. Paired t-test c. Chi-squared test of independence d. One proportion z-test OTwo sample t-test (independent means) (b) A Type II error in this context means the company finds evidence of an increase in sales, when in reality there is in sales.
Answers
Answer:
A) Option B: Paired t-test
B) The company finds "SUFFICIENT" evidence of an increase in sales, when in reality there is "A DECREASE" in sales
Step-by-step explanation:
A) Let's look at the options.
a) One sample t-test: This t-test is a statistical hypothesis test that's used to find out whether an unknown population mean has a different value from the sample mean.
b) Paired t-test: This is used to compare mean at different times from the same group.
c) Chi-squared test of independence: This test is one that is used to determine whether the associated variables are related or independent.
d) One proportion z-test: This test is used to compare an observed proportion to that of a theoretical proportion.
e) Two sample t-test: This is used to test if the unknown population mean that is gotten from two groups are equal or not.
Now, from the question, we see that A random sample of 30 branches is chosen, and the daily sales for these branches are recorded.
Later on, All the employees at these branches then undergo a customer skills training program, and shortly thereafter the daily sales at these 30 branches are again recorded.
This means that we are trying to compare the mean within the same group but at different times. This corresponds to the definition of Paired t-test.
B) A Type II error occurs when we accept a null hypothesis that is actually false.
The type II error in this case is that:
The company finds "SUFFICIENT" evidence of an increase in sales, when in reality there is "A DECREASE" in sales

Skylar owns a food truck that sells tacos and burritos. She sells each taco for $3 and each burrito for $6. Yesterday Skylar made a total of $600 in revenue from selling a total of 120 tacos and burritos. Graphically solve a system of equations in order to determine the number of tacos sold, x,x, and the number of burritos sold, yy.
Answers
Answer:
She sold 40 tacos and 80 burritos.
Step-by-step explanation:
Let's define the variables:
x = number of tacos sold
y = number of burritos sold
if Skylar sold x tacos, and each taco costs $3, then the total amount she gets is:
$3*x
And if she sold y burritos, and each one costs $6, then the total amount she gets is:
$6*y
combining these two, she has:
$3*x + $6*y
We know that she made a total revenue of $600, then we have the equation:
$3*x + $6*y = $600
We also know that in total, she sold 120 tacos and burritos, then:
x + y = 120
We have the system of equations:
$3*x + $6*y = $600
x + y = 120
To solve this, we need to start by isolating one of the variables in one of the equations, i will isolate x in the second equation:
x = 120 - y
Now we can replace that in the other equation to get
$3*(120 - y) + $6*y = $600
-$3*y + $360 + $6*y = $600
($6 - $3)*y + $360 = $600
$3*y + $360 = $600
$3*y = $600 - $360 = $240
y = $240/$3 = 80
She sold 80 burritos, and we know that:
x + y = 120
x + 80 = 120
x = 120 - 80 = 40
She sold 40 tacos.

what is the first term of an infinitely decreasing G.P whose sum is 16 and the second term is -0.5?
Answers
Answer:
8 + 6√2Step-by-step explanation:
Sum of infinite GP is:
a/(1 - r) = 16 andThe second term is:
ar = -0.5Eliminate r in the system:
a/(1-r) = 16 ⇒ a = 16 - 16r ⇒ 16r = 16 - a ⇒ r = 1 - a/16ar = -0.5 ⇒ r = -0.5/aCompare the two equations and solve for a:
1 - a/16 = -0.5/aMultiply both sides by 16a:
16a - a² = -8a² - 16a = 8 a² - 16a + 64 = 72(a - 8)² = 72a - 8 = ±√72a = 8 ± √72a = 8 + 6√2 a = 8 - 6√2, excluded as it is negative and makes common difference positive and so an increasing functiona = 8 - 6√2 = -0.4852 ⇒ r = -0.5/a = -0.5/-0.4852 = 1.03 > 1
