You play a game in which two coins are flipped. If both coins turn up tails, you win 1 point. How many points would you need to lose for each of the other outcomes so that the game is fair?
Answer with explanation:
When two coins are tossed
Total Sample Space ={T T,HT, TH, H H}=4
By getting , T T, total points won =1 Point
For, a fair game , you need to lose 1 point, so that sum of all the points
=1 -1
=0
The point = -1 , must be obtained from three outcomes which are {HT, TH, and H H}.
Sum of ,HT , TH and H H = -1
⇒S(H T) +S (TH) +S(H H)= -1, where S=Sum
If points obtained on each of three outcome are equal, then
[tex]S(HT)=\frac{-1}{3}\\\\S(TH)=\frac{-1}{3}\\\\S(HH)=\frac{-1}{3}[/tex]

Find three positive numbers whose sum is 12 and the sum of whose squares is as small as possible.
Answer:
4, 4, and 4.
The three positive numbers that satisfy the given conditions are
x = y = z = 4, and their sum is 12.
Given,
Sum of three numbers is 12.
Let the three positive numbers are x, y, and z.
1. To minimize the sum of their squares as
[tex]f(x, y, z) = x^2 + y^2 + z^2[/tex]
Subject to the constraint: Sum of three numbers is 12.
[tex]g(x, y, z) = x + y + z = 12[/tex]
2. Using Lagrangian function:
[tex]L(x, y, z, \lambda) = f(x, y, z) - \lambda(g(x, y, z) - 12)[/tex]
Substituting the value of f(x, y, z) = [tex]x^2 + y^2 + z^2[/tex] and g(x, y, z) = [tex]x + y + z - 12[/tex] into Lagrangian function gives
[tex]L(x, y, z, \lambda) = (x^2+y^2+z^2) - \lambda (x+ y+ z - 12)[/tex]
3. Now, take partial derivatives of L with respect to x, y, z, and λ,
[tex]\(\frac{{\partial L}}{{\partial x}}[/tex] = [tex]2x - \lambda\)[/tex]
[tex]\(\frac{{\partial L}}{{\partial y}}[/tex] = [tex]2y - \lambda\)[/tex]
[tex]\(\frac{{\partial L}}{{\partial z}}[/tex] = [tex]2z - \lambda\)[/tex]
[tex]\(\frac{{\partial L}}{{\partial \lambda}}[/tex] = [tex]-(x + y + z - 12)[/tex]
4. Now, set each derivative to zero to find the critical points.
Equation 1: [tex]\(\frac{{\partial L}}{{\partial x}}[/tex] = [tex]2x - \lambda\)[/tex] =0
Equation 2: [tex]\(\frac{{\partial L}}{{\partial y}}[/tex] = [tex]2y - \lambda\)[/tex] = 0
Equation 3: [tex]\(\frac{{\partial L}}{{\partial z}}[/tex] = [tex]2z - \lambda\)[/tex] = 0
Equation 4: [tex]\(\frac{{\partial L}}{{\partial \lambda}}[/tex] = [tex]-(x + y + z - 12)[/tex] = 0
Solving equations (1), (2), and (3) we get
[tex]2x - \lambda\)[/tex] =0x = λ/2
[tex]2y - \lambda\)[/tex] = 0y = λ/2
[tex]2z - \lambda\)[/tex] = 0z = λ/2.
5. Substituting the value x = y = z = λ/2 into equation (4) gives
[tex]-(x + y + z - 12) = 0[/tex]
- [tex](\lambda/2 + \lambda/2 + \lambda/2 -12)= 0[/tex]
[tex]-(3\lambda/2 - 12) = 0[/tex]
[tex]3\lambda/2 = 12[/tex]
[tex]\lambda = 8[/tex]
So, x = y = z = λ/2 = 4.
Therefore, the three positive numbers are 4, 4 and 4.

To earn money, George types papers for college students. For regular term papers, he charges by the page: $1.50 each. For scientific and technical papers, he charges more because they take longer to type. If he types forty-five regular pages and thirty-six technical pages, how much will he earn? What other information is needed to solve this problem?
George's earnings from typing forty-five regular pages are $67.50. To calculate his total earnings, the charge per page for thirty-six technical papers is needed, which is not provided in the question.
To calculate how much George will earn for typing papers, we must know the charge per page for both regular and technical papers. For regular term papers, the charge has been provided: $1.50 per page. However, the charge for technical papers has not been specified. Thus, additional information is needed: the rate George charges per page for technical papers. Without this rate, we cannot accurately calculate his total earnings.
Given that George types forty-five regular pages, his earnings from regular papers can be calculated as:
45 pages *$1.50 per page = $67.50
As for the technical papers, we must have the rate per page to calculate his earnings from the thirty-six technical pages he typed. Once we have this rate, it would be a similar calculation to the one done for regular papers.
The cafe where you work just ran out of coffee you are at the store to buy 1 1/2 pounds of coffee. You have to put a can with 3/4 pound of coffee into your shopping cart. How many more pounds do you need
Answer:
3/4
Step-by-step explanation:
I'm not very good at understanding word problems but I'll try to help using the info I already have.
You bought 3/4 pounds and you need a total of 1 1/2 pounds.
Find the common denominator which in this case is 4. Multiply 1 1/2 by 2/2 to get 1 2/4
You leave 3/4 alone because the denominator is already 4.
Convert 1 2/4 to a mixed number by taking away the 1 and adding 4 to the numerator leaving you with 6/4
6/4 - 3/4 = 3/4
Therefore you need 3/4 pounds left

Find the number a such that the line x = a bisects the area under the curve y = 1/x2 for 1 ≤ x ≤ 4. 8 5 (b) find the number b such that the line y = b bisects the area in part (a).
[tex]\( a = \frac{8}{5} \)[/tex] and [tex]\( b = \frac{3}{8} \)[/tex].
To find the number asuch that the line x = a bisects the area under the curve [tex]\( y = \frac{1}{{x^2}} \)[/tex] for [tex]\( 1 \leq x \leq 4 \)[/tex], we first need to find the total area under the curve in that interval. Then, we'll find the value of a such that the area to the left of x = a is equal to the area to the right of x = a.
The total area under the curve [tex]\( y = \frac{1}{{x^2}} \)[/tex] from x = 1 to x = 4 is given by the definite integral:
[tex]\[ A = \int_{1}^{4} \frac{1}{{x^2}} \, dx \][/tex]
[tex]\[ A = \int_{1}^{4} x^{-2} \, dx \][/tex]
[tex]\[ A = \left[ -\frac{1}{x} \right]_{1}^{4} \][/tex]
[tex]\[ A = -\frac{1}{4} + \frac{1}{1} \][/tex]
[tex]\[ A = 1 - \frac{1}{4} \][/tex]
[tex]\[ A = \frac{3}{4} \][/tex]
So, the total area under the curve is [tex]\( \frac{3}{4} \)[/tex].
To bisect this area, the area to the left of x = a and the area to the right of x = a must each be [tex]\( \frac{1}{2} \)[/tex] of the total area.
Let's integrate from x = 1 to x = a to find the area to the left of \( x = a \), then set it equal to [tex]\( \frac{1}{2} \)[/tex] of the total area:
[tex]\[ \int_{1}^{a} \frac{1}{{x^2}} \, dx = \frac{1}{2} \cdot \frac{3}{4} \][/tex]
[tex]\[ \left[ -\frac{1}{x} \right]_{1}^{a} = \frac{3}{8} \][/tex]
[tex]\[ -\frac{1}{a} + \frac{1}{1} = \frac{3}{8} \][/tex]
[tex]\[ -\frac{1}{a} + 1 = \frac{3}{8} \][/tex]
[tex]\[ -\frac{1}{a} = \frac{3}{8} - 1 \][/tex]
[tex]\[ -\frac{1}{a} = \frac{3}{8} - \frac{8}{8} \][/tex]
[tex]\[ -\frac{1}{a} = \frac{-5}{8} \][/tex]
[tex]\[ \frac{1}{a} = \frac{5}{8} \][/tex]
[tex]\[ a = \frac{8}{5} \][/tex]
So, [tex]\( a = \frac{8}{5} \)[/tex].
Now, to find the number b such that the line y = b bisects the area, we need to find the value of b such that the area above the line y = b is equal to the area below the line y = b.
The total area under the curve is [tex]\( \frac{3}{4} \)[/tex]. Since the curve is symmetric about the x-axis, the line y = b must pass through the midpoint of the total area, which is [tex]\( \frac{3}{8} \)[/tex] above the x-axis.
So, [tex]\( b = \frac{3}{8} \)[/tex].

Since triangle is isosceles then AB = BC
Equate the 2 sides, that is
4x - 21 = 2x - 7 ( subtract 2x from both sides )
2x - 21 = - 7 ( add 21 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7, hence
AB = 2x - 7 = (2 × 7) - 7 = 14 - 7 = 7
BC = 4x - 21 = (4 × 7) - 21 = 28 - 21 = 7
AC = x - 3 = 7 - 3 = 4

Step-by-step explanation:
The given quadrilateral is inscribed in a circle, so its opposite angles are supplementary, which means that the sum of their measures is 180∘.
The measures of the opposite angles in the quadrilateral are given as (6m + 1 3)∘ and (4m + 7)∘.
Equate the sum of the given measures to 180∘.
6m + 13 + 4m + 7 = 180
Combine like terms.
10m + 20 = 180
Subtract 20 from both sides.
10m = 160
Divide both sides by 10.
m = 16
Substitute 16 for m into the expression given for the measure of angle M and simplify.
6m = 6(16)
=96∘
Therefore, m∠M = 96∘.

Which is true about x, the quotient of the division problem shown below?
81 divided by 918
The quotient contains a repeating decimal.
The quotient contains a terminating decimal.
The quotient is a whole number less than 11.
The quotient is a whole number greater than 11.
Answer:
The quotient contains a terminating decimal and The quotient is a whole number less than 11.
Step-by-step explanation:
To answer this one, it's mandatory to remember that quotient, is the outcome of a ratio: a number (r) over another (s) (different than 0). In this case:[tex]\frac{81}{918}[/tex]. So q is equal to =0.08823529411.
Analyzing the number: 0.08823529411
This is not a repeating decimal, but it is a terminating decimal for it has an end.
The quotient is also a whole number less than 11.
The Whole Set of numbers is made up of the following numbers W ={0,1,2,...} and 0 < 11. Therefore it is true.
The quotient of 81 divided by 918 is a decimal that contains repeating digits.
The question asks about the quotient of the division problem 81 divided by 918. To find out the nature of the quotient, we can perform the division. The result of this division is not a whole number since 81 cannot evenly divide 918. Therefore, we will be looking at a decimal result. When we carry out the division, we notice that the decimal will not terminate shortly; thus, we can infer that the pattern of digits will start to repeat at some point. This tells us that the quotient contains a repeating decimal. Therefore, the correct answer is that the quotient contains a repeating decimal. It is not a whole number, nor is it terminating, and the quotient will be less than 1 since 81 is less than 918.
An engineer determines that the angle of elevation from her position to the top of a tower is 57o. She measures the angle of elevation again from a point 43 meters farther from the tower and finds it to be 27o. Both positions are due east of the tower. Find the height of the tower.
Answer:
54.65m
Step-by-step explanation:
This is going to be extremely difficult to explain. We have one large right triangle split up into 2 triangles: the first one has a base angle of 57 with unknown base length (y) and unknown height (x), and the second one has a base angle of 27 with unknown base length of y + 43 and unknown height (x. This is the same x from the first one and is what we are looking for...the height of the tower). We can find the vertex angle of the first triangle because 180 - 90 - 57 = 33. The side across from the 33 is y and the side adjacent to it is x so we have that tan33 = y/x. Not enough yet to do anything with. Our goal is to solve for that y value in order to sub it in to find x. Next we have to use some geometry. The larger triangle has a base angle of 27. The angle within that triangle that is supplementary to the 57 degree angle is 180 - 57 = 123. So now we have a triangle with 2 base angles measuring 123 and 27, and the vertex angle then is 180 - 123 - 27 = 30. That vertex angle of 30 added to the vertex angle of the first triangle is 63 degrees total. Now we can say that tan63 = (y+43)/x. Now we have 2 equations with 2 unknowns that allows us to solve them simultaneously. Solve each one for x. If
[tex]tan33=\frac{y}{x}[/tex], then
[tex]x=\frac{y}{tan33}[/tex].
If
[tex]tan63=\frac{y+43}{x}[/tex], then
[tex]x=\frac{y+43}{tan63}[/tex]
Now that these both equal x and x = x, we can set them equal to each other and solve for y:
[tex]\frac{y}{tan33}=\frac{y+43}{tan63}[/tex]
Cross multiply to get
[tex]tan33(y+43)=ytan63[/tex]
Distribute through the parenthesis to get
y tan33 + 43 tan33 = y tan 63.
Now get the terms with the y in them on the same side and factor out the common y:
y(tan33 - tan63) = -43 tan33
Divide to get the following expression:
[tex]y=\frac{-43tan33}{(tan33-tan63)}[/tex]
This division gives you the fact that y = 64.264 m. Now we add that to 43 to get the length of the large right triangle as 107.26444 m. What we now is enough information to solve for the height of the tower:
[tex]tan27=\frac{x}{107.2644}[/tex]
and x = 56.65 m
Phew!!!!! Hope I didn't lose you too too badly! This is not an easy problem to explain without being able to draw the picture like I do in my classroom!

The question is illustrated with the attached image.
First, calculate distance BC (x)
This is calculated using the following tan ratio

Make h the subject
[tex]h = x\tan(57)[/tex]
Next, calculate distance CD using the following tan ratio
[tex]\tan(27) = \frac{h}{CD}[/tex]
Make h the subject
[tex]h = CD \times \tan(27)[/tex]
From the attached image:
[tex]CD = x + 43[/tex]
So, we have:
[tex]h = (x + 43) \times \tan(27)[/tex]
Substitute [tex]h = x\tan(57)[/tex]
[tex]x \tan(57) = (x + 43) \times \tan(27)[/tex]
[tex]1.5398x = (x + 43) \times 0.5095[/tex]
Open brackets
[tex]1.5398x = 0.5095x + 21.9085[/tex]
Collect like terms
[tex]1.5398x - 0.5095x = 21.9085[/tex]
[tex]1.0303x = 21.9085[/tex]
Solve for x
[tex]x = \frac{21.9085}{1.0303}[/tex]
[tex]x = 21.2642[/tex]
Recall that:
[tex]h = x\tan(57)[/tex]
[tex]h = 21.2642 \times 1.5398[/tex]
[tex]h = 32.74[/tex]

Four times Joe’s age plus 2 times Tim’s ageequals 50. Tim’s age is also 2 less than Joe’s age.How old is Joe?
Answer:
Joe is 9 years old
Step-by-step explanation:
We can start by creating two different equations, one for each fact that we know about their ages.
Say that J is Joe's age
Say that T is Tim's age
Our first equation would then be:
4J + 2T = 50
J - 2 = T
Now that we know that T is J - 2, we can plug that in to the first equation.
4J + 2(J - 2) = 50
We can simplify this equation to solve for J
4J + 2J - 4 = 50
6J = 54
J = 9
Joe is 9 years old
