Six checkers are placed in three boxes: two red are in a box labeled "RR"; two black are in a box labelled "BB"; a red and a black are in a box labelled "RB". How can you tell, by taking only one checker out of one of the boxes (and without looking at any of the other checkers), the correct content of all three boxes?
Answe and Step-by-step explanation:
Looking at the question the way it was asked, it is easy because it said they have been labelled, so you don't have to stress yourself. Although, if what is intended is, the labelling got wrong along the way and how do you identify the correct one? Then this is what to do:
Go to the one labelled RB. Since I'm assuming that the labelling got wrong, if you pick a red, it means what we have should be a RR and if we picked a black, it means what we have is a BB and we can't have a RB because it was labelled wrongly.
Let's assume he saw a red,
We know that the BB box was labelled wrongly, and we already determined that the box with RB is a RR. Therefore, the box BB can never be RR(because we've seen it already) and it's certainly not BB (due to the fact that they were labelled wrongly). So we have only one option left which is it being RB and whatever we have left will be BB.
If we assume what was picked from the wrongly labelled RB is black.
We know that the RR box was labelled wrongly, and we already determined that the box with RB is a BB. Therefore, the box RR can never be BB and it's certainly not RR (due to the fact that they were labelled wrongly). So we have only one option left which is it being RB and whatever we have left will be RR.

Given:
The figure.
To find:
The value of a.
Solution:
We know that, in a right angled triangle
[tex]\tan \theta =\dfrac{Perpendicular}{Base}[/tex]
In the given triangle,
[tex]\tan (38^\circ) =\dfrac{6}{a}[/tex]
Multiply both sides by a.
[tex]\tan (38^\circ)\times a=6[/tex]
Divide both sides by [tex]\tan (38^\circ)[/tex]
[tex]a =\dfrac{6}{\tan (38^\circ)}[/tex]
The value of a is [tex]\dfrac{6}{\tan (38^\circ)}[/tex].
Therefore, the correct option is b.

Y =-x-2
What is the other equation? Write in slope-intercept form. Start with y =
Please help:)
Answer:
y=4x+3
Step-by-step explanation:
The given equation y=-x-2 is the equation of the line passing through the points (-1,-1) and (-2,0) in the given graph.
From the graph, the other line is passing through the points (0,3) and (-1,-1).
So, the equation of the line passing through the two points is
[tex]y-3=(x-0)\times \frac{-1-3}{-1-0} \\\\y-3=x \times \frac{-4}{-1} \\\\y-3= x \times4 \\\\y=4x+3[/tex]
Hence, the equation of the other line is y=4x+3.

if you asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26 and older, what type of variable is this?
If we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.
What is a Discrete variable?A discrete variable is one whose value can be determined by counting. A continuous variable is one whose value can be determined through measurement. A random variable is one whose value is the numerical result of a random phenomenon. The possible values of a discrete random variable X are countable. As an example, It is a type of Discrete variable if we asked people their age and you collected it as 5, 6, 10, 11, 15, 16, 20, 21, 25, 26, and older. There are two types of quantitative variables: discrete variables and continuous variables. Counts are represented by discrete variables (e.g. the number of objects in a collection). Continuous variables represent quantifiable quantities (e.g. water volume or weight).Therefore, if we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.

You are designing a rectangular playground on your scale the verticals of the rectangle are (6,3), (6,5) and (8,3). What are the coordinates of the fourth vertex
Answer:
The coordinates of the fourth vertex are (8,5)
Step-by-step explanation:
We need to take note that a rectangle is a shape that has 4 sides, with two of them of equal length.
It will also help if we can visualize the points on the graph.
We are given the location of three of the four vertices. These are (6,3), (6,5) ,and (8,3). Let the 4th Vertice be (x,y)
The length of the triangle can be obtained by subtracting the y-coordinates of the vertices.
(6,3) - (6,5)
This will be +3 and +5
5-3 =2
Therefore, the length of the triangle is 2 units on the left side.
Recall that the length of the left side has to be equal to the length of the right side.
Therefore
y-3 =2
y = 5
We will repeat the same process to get the x-coordinate from the breadth
Breadth = 8-6 =2
x-6 =2
x=8
Hence the x = 8
Therefore, the coordinates of the fourth vertex are (8,5)
The equation f(x)=3x can be written as x^3=k. Find the value of k
After solving the equation we get the value of k as ₋3, and also proved that the function is odd function.
Given the equation is f(x) =x³₋(k₊3) x²₊3x
also we know that the f(x) is an odd function, then by definition we write
f(₋x) = ₋f(x)
f(₋x) = (₋x)³ ₋ (k ₊ 3)(₋x)² ₊ 3(₋x)
= ₋ [x³ ₋ (k ₊ 3)x² ₊ 3x] = ₋x³ ₊ (k ₊ 3)x² ₋ 3x
(₋x)³ ₋ (k ₊ 3)(₋x)² ₊ 3(₋x) = ₋x³ ₊ (k ₊ 3)x² ₋ 3x
₋x³ ₋ kx² ₋ 3x² ₋ 3x = ₋x³ ₊ kx² ₊ 3x² ₋ 3x
₋kx² ₋ 3x² = kx² ₊ 3x²
2kx² ₊ 6x² = 0
2k + 6 = 0
k = -3
Therefore, k has the result of reducing f(x) to x³ ₊ 3x. When we examine this function to check if it's an odd function, we see that
(₋x)³ ₊ 3(₋x) = ₋x³ ₋ 3x = ₋ [x³ ₊ 3x]
Hence the value of k is ₋3 and the function is an odd function.

The variables x and y vary inversely. Use the given values to write an equation relating x and y. x=7/2 y=3/5
Answer:
x = 21/10yStep-by-step explanation:
If the variables x and y vary inversely, this is expressed as;
x ∝ 1/y
x = k/y
k is the constant of proportionality
Given;
x = 7/2 and y = 3/5
Substitute;
7/2 =k/(3/5)
Cross multiply
k = 7/2 * 3/5
k = 21/10
Substitute the value of k into the formula;
x = k/y
x = (21/10)/y
x = 21/10 * 1/y
x = 21/10y
Hence the equation relating x and y is x = 21/10y

The polynomial 9x^2 + 4 is equivalent to (3x+2i)(3x-2i). The answer is A.
Polynomials are algebraic expressions that consist of variables and coefficients where arithmetic operations can be performed.
A polynomial is expanded if no variable appears within parentheses and all like terms have been combined.
To expand a polynomial, multiply its factors (often by using the distributive property) or perform the indicated operations. Then combine all like terms.
Expanding each of the options provided using FOIL method:
a) (3x+2i)(3x-2i)
= 9x^2 - 2ix + 2ix - 4i^2
= 9x^2 - 4i^2 *(i^2 = -1) note that i is an imaginary number and i squared is equal to -1
= 9x^2 - 4(-1)
= 9x^2 + 4
b) (3x+2)(3x-2)
= 9x^2 + 6x - 6x - 4
= 9x^2 - 4
c) (3x + 2i)^2
= 9x^2 + 6ix + 6ix + 4i^2 *(i^2 = -1)
= 9x^2 + 12ix - 4
d) (3x + 2)^2
= 9x^2 + 6x + 6x + 4
= 9x^2 + 12x + 4
Hence, the polynomial 9x^2 + 4 is equivalent to (3x+2i)(3x-2i). The answer is A.

A clothing store is running an offer on men's shirts. When two shirts are bought at regular price, the third shirt is 50% off. Jeremy decided to buy three shirts for his brother using the offer. The regular price for a shirt is $36.00. Based on a tax rate of 7.50% that is applied after the discount, Jeremy paid a total of $ 100 for three shirts, including tax.
Answer: $96.75
Step-by-step explanation:
Regular price is $36 and the third shirt will come at a 50% discount.
Total price for the 3 shirts is;
= 36 + 36 + (36 * 50%)
= $90
The total after-tax is;
= 90 * ( 1 + tax rate)
= 90 * ( 1 + 7.50%)
= $96.75
I am unsure what the question is but the total amount that Jeremy should pay is $96.75.

The value of x is 5.
Given that, m∠VUT = 175° , m∠VUJ = 17x-3 and m∠JUT = 17x+8.
The angle where two rays meet is represented as vertex.
Each and every vertex , where two rays meet have some angle between them.
The symbol that represents angle is, “∠”.
Here, you can deal with the angle and find the value of x by just equating the given equations upon the given angle m∠VUT = 175° .
we get,
m∠VUT = m∠VUJ + m∠JUT
175 = 17x-3 + 17x+8
175 = 34x + 5
175-5 = 34x
170 = 34x
170/34 = x
x = 5.
Therefore, the value of x is 5.
