Answer:
$2500
Step-by-step explanation:
Given that,
The lost percentage = 9%
Amount she had = $22,750
We need to find Mrs. Fisher's original investment.
As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.
So,
[tex]91\%\ of \ x=22,750\\\\\dfrac{91}{100}x=22,750\\\\x=\dfrac{22,750\times 100}{91}\\\\x=\$25000[/tex]
So, her original investment is equal to $25000.

Step-by-step explanation:
Clockwise would mean a rotation to the right, and since the triangle is already plotted, just use the little picture turning icon( in the top right corner of the photo of the problem) to turn, and look at the triangle in the original graph to see how it moved.
Then click the button three more time until you get the photo right-side-up, and choose which option is the best answer.

A potato chip company produces a large number of potato chip bags each day and wants to investigate whether a new packaging machine will lower the proportion of bags that are damaged. The company selected a random sample of 150 bags from the old machine and found that 15 percent of the bags were damaged, then selected a random sample of 200 bags from the new machine and found that 8 percent were damaged. Let p^O represent the sample proportion of bags packaged on the old machine that are damaged, pˆN represent the sample proportion of bags packaged on the new machine that are damaged, pˆC represent the combined proportion of damaged bags from both machines, and nO and nN represent the respective sample sizes for the old machine and new machine.
Required:
Have the conditions for statistical inference for testing a difference in population proportions been met?
Answer:
The conditions for the approximation have been met
Step-by-step explanation:
Random samples on both cases and
p∧o proportion of bags packaged on the old machine that are damaged
p∧n sample proportion of bags packaged on the new machine that are damaged
p∧c = ( p∧o + p∧n ) / (nO + nN )
p∧o = 15 % p∧o = 0,15 nO = 150
p∧o * nO = 0,15 *150 p∧o * nO = 22,5
p∧n = 8 % p∧n = 0,08 nN = 200
p∧n*nN = 0,08 * 200 p∧n*nN = 16
Both p∧n*nN and p∧o * nO are bigger than 5
Therefore both samples are big enough for the approximation of the binomial distribution to normal distribution

Answer:
[tex]f(8) = 81[/tex]
[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]
Step-by-step explanation:
Solving (a):
[tex]f(x) = x^2 + 2x +1[/tex]
[tex]g(x) = x - 5[/tex]
Solve for f(8)
We have:
[tex]f(x) = x^2 + 2x +1[/tex]
Substitute 8 for x
[tex]f(8) = 8^2 + 2*8 +1[/tex]
Solve
[tex]f(8) = 64 + 16 +1[/tex]
[tex]f(8) = 81[/tex]
Solving (b):
[tex](g\ o\ f)(x)[/tex]
This is solved by:
[tex](g\ o\ f)(x) = g(f(x))[/tex]
So, we have:
[tex]g(x) = x - 5[/tex]
[tex]g(f(x)) = f(x) - 5[/tex]
Substitute: [tex]f(x) = x^2 + 2x +1[/tex]
[tex]g(f(x)) = x^2 + 2x + 1 - 5[/tex]
[tex]g(f(x)) = x^2 + 2x -4[/tex]
Hence:
[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]

I need help!! Please solve theses using formulas and please explain.
Answer:
[tex]4 \times - 2 {}^{n - 1} [/tex]
Step-by-step explanation:
Use the formula.
[tex]f(n) = f(1) \times {r}^{n - 1} [/tex]
where f(1) is the first terms, r is the common ratio, and n is our undefined term.
4 is our first term. so
f(1)=4.
Our common ratio is -2 so
r=-2.
[tex]4 \times - 2 {}^{n - 1} [/tex]

Laurel divided 2/3 of a gallon of paint into 4 containers. How much of the of the
paint was put into each container?
Answer: 1/6 of the paint went to each container
Step-by-step explanation: Since we know he had 2/3 of a gallon of paint and they were divided into 4 containers, we have to divide 2/3 by 4 and when you do that you get 0.16666 continuous but in fraction for you arrive at 1/6 of a gallon of paint
is this right. ......... I need help

Select the value of x that makes the equation
“-3(x + 10) + 2x = 30” true.
1. 60
2. 0
3. 30
4. -60
5. -20
Answer:
-60
Step-by-step explanation:
-3(x + 10) + 2x = 30 becomes -3x - 30 + 2x = 30 after having performed the multiplication. Combining like terms, we get -x = 60, so that x must be -60 (Answer 4)

Rosalina just started a new job. She has $500 in her bank account. Every week, she deposits $40 into her bank account. Write an expression to represent how much Rosalina has in her account at any given time using x to represent the number of weeks. please help!!!
Answer:
500 + (40x)
Step-by-step explanation:
she already has 500 in her bank account and there are multiple weeks. 40 dollars per week would be 40x since we don’t know how many weeks. then put it in an equation!
Answer:500 + 40w = m
Step-by-step explanation:
500 is the amount you had already then you add 40 per a week so you times that by w depending on the weeks and m is money overall.
this should be the answer

Find the value of x in the triangle shown below 8 2
In the triangle in question, x has a value of √68. The triangle is right - angled triangle based on the dimensions provided. According to this, the neighboring angle will also be x°.
What is an angle?An angle is a shape made up of two rays that share a terminus and is designated by the name of the angle (the vertex).
The plane that contains the rays contains the angles created by two beams. The meeting of two planes might also result in an angle. These are referred to as dihedral angles.
An angle is created when two straight lines or rays intersect at the same point. The point where all points converge is known as an angle's vertex.
The Roman word angulus, which means "corner," is where the term "angle" comes from. In plane geometry, an angle is a shape made up of two rays or lines with the same termination.
In the triangle in question, x has a value of √68.
The triangle is right- angled triangle based on the dimensions provided. According to this, the neighboring angle will also be √68.
Therefore, a given triangle's angles will all be expressed mathematically as -
Using Pythagoras theorem,
[tex]x^{2} = 8^2 + 2^2\\x^{2} = 64 + 4\\x^{2} = 68\\x = \sqrt{68}[/tex]
As a result, the given triangle's x value is √68.

Answer:
h = 20 ftStep-by-step explanation:
Given,
Volume = 5600 sq.ft
Length = 35 ft
Width = 8 ft
Therefore,
By the problem,
[tex]height = \frac{volume}{length \times width} [/tex]
[tex] = > h = \frac{5600}{35 \times 8} ft[/tex]
=> h = 20 ft (Ans)

Answer:
√29
Step-by-step explanation:
We can call the given points A(3, 4) and B(-2, 6).
The right triangle with segment AB as a hypotenuse can best be drawn along grid lines. Then the vertical leg is the difference of y-coordinates: 6-4 = 2, and the horizontal leg is the difference of x-coordinates: 3 -(-2) = 5.
The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs.
AB² = 2² + 5²
AB² = 4 + 25 = 29
Taking the square root, we find the length of the line segment between the points to be ...
AB = √29
