Answer:  The list price was $1815.00.  

Step-by-step explanation:  Given that the discount on a LCD TV is $240 and the sale price is $1575.00.

We are to find the list price.

The discount is given on the price that is listen on the LCD TV.

So, the list price will be equal to the sum of the sale price and the discount price.

Therefore, the required list price of the LCD TV is given by

[tex]L.P.\\\\=\textup{sale price}+\textup{discount}\\\\=\$(1575.00+240.00)\\\\=\$1815.00.[/tex]

Thus, the list price was $1815.00.  

Answer:

The probability is 0.995 ( approx ).

Step-by-step explanation:

Let X represents the event of baby girl,

The probability of a baby being a girl is, p = 0.469,

So, the probability of a baby who is not a girl is, q = 1 - 0.469 = 0.531,

Also, the total number of experiment, n = 7

Thus, by the binomial distribution formula,

[tex]P(x)=^nC_x(p)^x q^{n-x}[/tex]

Where, [tex]^nC_x=\frac{n!}{x!(n-x)!}[/tex]

The probability that all babies are girl or there is no baby boy,

[tex]P(X=7)=^7C_7(0.469)^7(0.531)^{7-7}[/tex]

[tex]=0.00499125661758[/tex]

Hence, the probability that at least one of them is a boy​ = 1 - P(X=7)

= 1 - 0.00499125661758

= 0.995008743382

≈ 0.995

Answer:

$1210

Step-by-step explanation:

Let x be total amount

First John spent $110 on a radio and 4/11 of what was left on presents for his friends so he was left with

[tex]\frac{7}{11}(x-110)=\frac{7}{11}x-70[/tex]

Then he put 2/5 of his remaining money into a checking account

[tex]\frac{3}{5}\left(\frac{7}{11}x-70\right)[/tex]

Rest he donated to charity

[tex]420=\frac{3}{5}\left(\frac{7}{11}x-70\right)\\\Rightarrow \left(\frac{7}{11}x-70\right)=\frac{2100}{3}\\\Rightarrow \frac{7}{11}x-70=700\\\Rightarrow \frac{7}{11}x=770\\\Rightarrow x=1210[/tex]

Hence total amount of money John originally had was $1210

Answer:

21 % below what she needs

Step-by-step explanation:

She had hit 12, 10 and 9

This averages to

(12+10+9)/3 = 31/3 =10 1/3

She needs 13

Percentage = (needed-actual)/needed * 100%

                    = (13-10 1/3) / 13 * 100%

                    = (2 2/3) /13 * 100%

                    =.205128205 * 100%

                   =20.5128205%

To the nearest whole number

                      21 %

She is 21 % below what she needs

Samantha's current average free throw percentage is 15 percentage points away from the 65% needed to earn her wellness challenge chip.

Samantha is working on improving her free throw percentage in basketball, and she needs to calculate how far her average is from the required target to earn her wellness challenge chip. To determine her average free throw percentage, we first calculate her average number of successful shots by adding her last three attempts and dividing by three: (12 + 10 + 9) / 3 = 31 / 3 = 10.33, rounded to 10 successful shots on average. Since she takes 20 shots each time, her average percentage is (10 / 20) * 100 = 50%.

To earn her chip, she needs to hit 13 out of 20 free throws, which is (13 / 20) * 100 = 65%. The difference between her current average and the needed percentage is 65% - 50% = 15%. Rounding to the nearest whole number, she is 15 percentage points away from the required free throw percentage to succeed in the challenge.

Answer:

$2000 a year.

Step-by-step explanation:

Let's find the answer by using the following formula:

taxes=(house assessment)*(tax rate) for the initial conditions we have:

(1600/year)=(64000)*(tax rate)

(1600/year)/(64000)=(tax rate)

tax rate=0.025/year

For the current conditions we have:

taxes=(house assessment)*(tax rate)

taxes=(80000)*(0.025/year)

taxes=2000/year

So, the taxes will be $2000 a year.

Answer:[tex]\frac{22}{3}[/tex],[tex]2\dot \sqrt{\frac{11}{3}}[/tex]

Step-by-step explanation:

Given

rectangle with its base on x-axis

and other two corners at parabola

and parabola is downward facing symmetric about y-axis

let y be the y co-ordinate of the corner thus x co-ordinate is given by

[tex]x=\pm \sqrt{11-y}[/tex]

Thus lengths of rectangle is [tex]2\sqrt{11-y}[/tex] & y

Area [tex]=y\times 2\sqrt{11-y}[/tex]

differentiating w.r.t to y for maximum area

[tex]\frac{\mathrm{d} A}{\mathrm{d} y}=2\times \sqrt{11-y}-\frac{y}{2\dot \sqrt{11-y}}=0[/tex]

we get y=[tex]\frac{22}{3}[/tex]

and [tex]x=\pm \sqrt{\frac{11}{3}}[/tex]

Answer:

total profit=$607.278

Step-by-step explanation:

company's profit in 1985= $535 million

company's profit in 1990=$570 million

growth rate = [tex]\frac{570-535}{535}\times 100[/tex]

                    = [tex]\frac{35}{535} \times 100[/tex]

                    = 6.54 %

profit in year 1995 will be = [tex]\frac{6.54}{100}\times 570 =\ \$37.278[/tex]

hence total profit= $570+$37.278

                             = $607.278

I'm partial to solving with generating functions. Let

[tex]T(x)=\displaystyle\sum_{n\ge0}t_nx^n[/tex]

Multiply both sides of the recurrence by [tex]x^{n+2}[/tex] and sum over all [tex]n\ge0[/tex].

[tex]\displaystyle\sum_{n\ge0}2t_{n+2}x^{n+2}=\sum_{n\ge0}3t_{n+1}x^{n+2}+\sum_{n\ge0}2t_nx^{n+2}[/tex]

Shift the indices and factor out powers of [tex]x[/tex] as needed so that each series starts at the same index and power of [tex]x[/tex].

[tex]\displaystyle2\sum_{n\ge2}2t_nx^n=3x\sum_{n\ge1}t_nx^n+2x^2\sum_{n\ge0}t_nx^n[/tex]

Now we can write each series in terms of the generating function [tex]T(x)[/tex]. Pull out the first few terms so that each series starts at the same index [tex]n=0[/tex].

[tex]2(T(x)-t_0-t_1x)=3x(T(x)-t_0)+2x^2T(x)[/tex]

Solve for [tex]T(x)[/tex]:

[tex]T(x)=\dfrac{2-3x}{2-3x-2x^2}=\dfrac{2-3x}{(2+x)(1-2x)}[/tex]

Splitting into partial fractions gives

[tex]T(x)=\dfrac85\dfrac1{2+x}+\dfrac15\dfrac1{1-2x}[/tex]

which we can write as geometric series,

[tex]T(x)=\displaystyle\frac8{10}\sum_{n\ge0}\left(-\frac x2\right)^n+\frac15\sum_{n\ge0}(2x)^n[/tex]

[tex]T(x)=\displaystyle\sum_{n\ge0}\left(\frac45\left(-\frac12\right)^n+\frac{2^n}5\right)x^n[/tex]

which tells us

[tex]\boxed{t_n=\dfrac45\left(-\dfrac12\right)^n+\dfrac{2^n}5}[/tex]

# # #

Just to illustrate another method you could consider, you can write the second recurrence in matrix form as

[tex]49y_{n+2}=-16y_n\implies y_{n+2}=-\dfrac{16}{49}y_n\implies\begin{bmatrix}y_{n+2}\\y_{n+1}\end{bmatrix}=\begin{bmatrix}0&-\frac{16}{49}\\1&0\end{bmatrix}\begin{bmatrix}y_{n+1}\\y_n\end{bmatrix}[/tex]

By substitution, you can show that

[tex]\begin{bmatrix}y_{n+2}\\y_{n+1}\end{bmatrix}=\begin{bmatrix}0&-\frac{16}{49}\\1&0\end{bmatrix}^{n+1}\begin{bmatrix}y_1\\y_0\end{bmatrix}[/tex]

or

[tex]\begin{bmatrix}y_n\\y_{n-1}\end{bmatrix}=\begin{bmatrix}0&-\frac{16}{49}\\1&0\end{bmatrix}^{n-1}\begin{bmatrix}y_1\\y_0\end{bmatrix}[/tex]

Then solving the recurrence is a matter of diagonalizing the coefficient matrix, raising to the power of [tex]n-1[/tex], then multiplying by the column vector containing the initial values. The solution itself would be the entry in the first row of the resulting matrix.

Answer:

163

Step-by-step explanation:

So n=391.

This means p=23 and q=17 where p*q=n.

[tex] \lambda (391)=lcm(23-1,17-1)=lcm(22,16)=2*8*11=16*11=176. [/tex]

We want to choose e so that e is between 1 and 176 and the gcd(e,176)=1.

There is only one number in your list that is between 1 and 176... Hopefully the gcd(163,176)=1.

It does. See notes below for checking it:

176=2(88)=2(4*22)=2(2)(2)(2)(11)

None of the prime factors of 176 divide 163 so we are good.

The answer is 163.

Answer:

8710 units

Step-by-step explanation:

Step 1: Write all the data

Fixed cost: $9000

Average variable cost: 9.3 per unit

Total cost: 90,000

Total units: x

Step 2: Find the total variable cost

Average variable cost is per unit so it has to be multiplied by the number of units to find the total variable cost.

Total variable cost = average variable cost per unit x number of units

Total variable cost = 9.3x

Step 3: Make the formula for finding x

Total cost = total fixed cost + total variable cost

90,000 = 9000 + 9.3x

81000 = 9.3x

x = 8709.67

Rounded off to 8710 units

Answer:

1. { a, b, c, d, e, h }

2. { f, g, i }

Step-by-step explanation:

Given sets,

A = {a, b, c, d, e},

B = {a, c, f, g, i}

Universal set , ∪ = {a, b, c, d, e, f, g, h, i},

1. Since, [tex]B^c[/tex] = elements of universal set which are not in set B

=  U - B

= { b, d, e, h },

Thus,

[tex]A\cup B^c[/tex] = All elements of A and [tex]B^c[/tex]

= { a, b, c, d, e, h }

2. B - A = elements of set B which are not in set A

Answer:

Total number of ways will be 209

Step-by-step explanation:

There are 6 boys and 4 girls in a group and 4 children are to be selected.

We have to find the number of ways that 4 children can be selected if at least one boy must be in the group of 4.

So the groups can be arranged as

(1 Boy + 3 girls), (2 Boy + 2 girls), (3 Boys + 1 girl), (4 boys)

Now we will find the combinations in which these arrangements can be done.

1 Boy and 3 girls = [tex]^{6}C_{1}\times^{4}C_{3}=6\times4[/tex]=24

2 Boy and 2 girls=[tex]^{6}C_{2}\times^{4}C_{2}=\frac{6!}{4!\times2!}\times\frac{4!}{2!\times2!}=15\times6=90[/tex]

3 Boys and 1 girl = [tex]^{6}C_{3}\times^{4}C_{1}=\frac{6!}{4!\times2!}\times\frac{4!}{3!}=\frac{6\times5\times4}{3 \times2} \times4=80[/tex]

4 Boys = [tex]^{6}C_{4}=\frac{6!}{4!\times2!} =\frac{6\times 5}{2\times1}=15[/tex]

Now total number of ways = 24 + 90 + 80 + 15 = 209

Final answer:

To solve for the width of the rectangle, define the width as w, set up the equation 144 = w(w + 10), and factor the resulting quadratic equation to find w = 8 inches. Hence, the rectangle's dimensions are 8 inches in width and 18 inches in length.

Explanation:

To find the dimensions of a rectangle with an area of 144 square inches where the length is 10 inches longer than its width, we first recall the formula for the area of a rectangle:

Area = Length × Width

Let's define the width as w, and since the length is 10 inches longer, we can say the length is w + 10. Plugging these into the area formula we get:

144 = w × (w + 10)

Now, we have a quadratic equation to solve for w:

Expand the equation: 144 = w2 + 10w

Subtract 144 from both sides to set the equation to zero: w2 + 10w - 144 = 0

Factor the quadratic equation: (w + 18)(w - 8) = 0

Solve for w: w = -18 or w = 8 (since width cannot be negative, w = 8 is the solution.)

Therefore, the dimensions of the rectangle are a width of 8 inches and a length of 18 inches (8 + 10).

Answer: Null hypothesis = [tex]H_0:p=0.74[/tex]

Alternative hypothesis = [tex]H_1:p\neq0.24[/tex]

Step-by-step explanation:

Given claim : 74% of workers got their job through college.

In proportion , 0.74 of workers got their job through college.

Let p be the proportion of workers got their job through college.

Then claim : [tex]p=0.74[/tex]

We know that the null hypothesis always takes equality sign and alternative hypothesis takes just opposite of the null hypothesis.

Thus, Null hypothesis = [tex]H_0:p=0.74[/tex]

Alternative hypothesis = [tex]H_1:p\neq0.24[/tex]

Answer:

So anyways the equation appears to be [tex]y=(x+4)^3+3[/tex].

Step-by-step explanation:

It looks like a cubic to me.

That is the parent function looks like [tex]f(x)=x^3[/tex].

I'm going to identify the transformations here by using the zero of the function I called f.  So where has the point (0,0) on [tex]y=x^3[/tex] wonder to in the new graph.  It appears to be (-4,3).  So the graph moved left 4 units and up 3 units.

f(x+4)+3 moves the graph left 4 and up 3.

----------Other notes:

f(x-4)+3 moves the graph right 4 and up 3.

f(x+4)-3 moves the graph left 4 and down 3.

f(x-4)-3 moves the graph right 4 and down 3.

So anyways the equation appears to be [tex]y=(x+4)^3+3[/tex].

To determine the equation of a transformed basic function, we typically look at how the graph's shape compares to one of the standard basic functions. The basic functions include linear functions, quadratic functions, absolute value functions, square root functions, cubic functions, and exponential and logarithmic functions. We also consider basic trigonometry functions for periodic graphs.
To find the equation, we need to identify four main transformations that may have been applied to the basic function:
1. **Vertical stretching/shrinking**: If the graph is stretched or shrunk vertically, this is represented by a multiplication factor `a` in front of the basic function `f(x)`.
2. **Horizontal stretching/shrinking**: If the graph is stretched or shrunk horizontally, this is represented by a factor within the function's argument, such as `f(bx)`, where `1/b` is the stretching/shrinking factor.
3. **Vertical shifting**: If the graph is shifted up or down, a constant `c` is added or subtracted from the function, giving `f(x) + c`.
4. **Horizontal shifting**: If the graph is shifted left or right, the function's input is adjusted by adding or subtracting a constant `d` within the argument of the function, yielding `f(x - d)`.
5. **Reflections**: If the graph is flipped over the x-axis, this is represented by a negative sign in front of the `a` factor. If it's flipped over the y-axis, the negative sign is inside the function's argument, `f(-x)`.
Without any specific details about the graph's appearance, the points, or what basic function it resembles, it is impossible to provide the exact transformed function. However, for illustrative purposes, I’ll demonstrate how one might find the equation for a transformed quadratic function based on hypothetical graph observations:
Suppose you find that the graph looks like a parabola that opens upwards and has been:
- Stretched vertically by a factor of 3 (vertical stretch)
- Compressed horizontally by a factor of 1/2 (horizontal stretch)
- Shifted up by 5 units (vertical shift)
- Shifted to the right by 4 units (horizontal shift)
With these observations, you would start with the standard quadratic function, `f(x) = x^2`, and apply the transformations:
1. Vertical stretch by 3: `f(x) = 3x^2`
2. Horizontal compression by a factor of 1/2, which is equivalent to stretching by a factor of 2: `f(x) = 3(x/2)^2 = 3(x^2/4) = (3/4)x^2`
3. Vertical shift up by 5 units: `f(x) = (3/4)x^2 + 5`
4. Horizontal shift right by 4 units: `f(x) = (3/4)(x - 4)^2 + 5`
The transformed function based on the hypothetical scenario would be `f(x) = (3/4)(x - 4)^2 + 5`.
Without specifics of the graph in question, you would follow a similar process: identify the basic function type based on the shape of the graph and apply the relevant transformations.

Answer:

The required sales in units to achieve its target net income is 1,237,500 units.

Step-by-step explanation:

From the given information it is clear that

Fixed cost = $480,000

Selling Price = $6 per unit

Variable Cost = $4.4 per unit

Target net income = $1,500,000

We need to find the required sales in units to achieve its target net income.

[tex]Units=\frac{\text{Fixed cost + Target net income}}{\text{Selling Price - Variable Cost}}[/tex]

[tex]Units=\frac{480000+1500000}{6-4.4}[/tex]

[tex]Units=\frac{1980000}{1.6}[/tex]

[tex]Units=1237500[/tex]

Therefore the required sales in units to achieve its target net income is 1,237,500 units.

To cover a 6,000 square foot lawn, 192 ounces of fertilizer will be required. With the given cost of the fertilizer, the total cost to fertilize the lawn would be $9.36.

(a) To calculate how many ounces are required to cover a 6,000 square foot lawn, we can set up a proportion.

40 ounces of Lazy Lawn fertilizer covers 1,250 square feet, so let's represent it as 40/1250. We know that we have a 6,000 square foot lawn but we don't know how many ounces it requires, let's represent it as x/6000.

Our proportion will then be as follows: 40/1250 = x/6000. Cross multiply to find 'x', we will get x = [(40*6000)/1250] = 192 ounces.

(b) Now, to calculate the total cost we first need to know how many 24 ounce bags we will need. 192 ounces divided by 24 ounces per bag gives us 8 bags. Then we calculate the cost, 8 bags times $1.17 per bag gives us a total of $9.36.

Answer:

hence rate interest r = 41.176%

Step-by-step explanation:

The amount borrowed= $680

amount payed back = $750

therefore, interest incurred = 750-680= $70

time, t= 3 months = 3/12= 0.25 years

rate%, r

we know that SI= [tex]\frac{PRT}{100}[/tex]

70= [tex]\frac{680\timesr\0.25}{100}[/tex]

r=[tex]\frac{7000}{0.25\times680} = 41.176[/tex]

Answer:

Dryer will pay for itself in 63 months or 5 years and 3 months.

Step-by-step explanation:

Let after x months new dryer will pay for itself.

Old dryer is costing $25 to operate so after x months it will cost = 25x

Similarly new dryer which cost $630 and operating cost is $15 per month.

So after x months new drier will cost = $(630 + 15x)

If the new dryer pay for itself in x months then total cost of both the dryers after x months should be same.

Therefore, 25x = 630 + 15x

25x - 15x = 630

10x = 630

x = [tex]\frac{630}{10}[/tex]

x = 63 months

Or x = 5 years 3 months

Answer is 63 months or 5 years 3 months.

We have

[tex]\dfrac{\partial(y\cos(xy)+3x^2)}{\partial y}=\cos(xy)-xy\sin(xy)[/tex]

[tex]\dfrac{\partial(x\cos(xy)+2y)}{\partial x}=\cos(xy)-xy\sin(xy)[/tex]

so the ODE is indeed exact. Then there's a solution of the form [tex]f(x,y)=C[/tex] such that

[tex]\dfrac{\partial f}{\partial x}=y\cos(xy)+3x^2[/tex]

[tex]\implies f(x,y)=\sin(xy)+x^3+g(y)[/tex]

Differentiating wrt [tex]y[/tex] gives

[tex]\dfrac{\partial f}{\partial y}=x\cos(xy)+2y=x\cos(xy)+g'(y)[/tex]

[tex]\implies g'(y)=2y\implies g(y)=y^2+C[/tex]

Then the solution to the ODE is

[tex]f(x,y)=\boxed{\sin(xy)+x^3+y^2=C}[/tex]

Answer:

The full budget has a total value of $160,000

Step-by-step explanation:

This is a simple ratio problem and can be solved using the Rule of Three property. The Rule of Three is used to compare two ratios and find the missing part. In this case the ratios would be the following.

[tex]\frac{64,000}{40 percent} = \frac{x}{100 percent}[/tex]

[tex]\frac{64,000 * 100 percent}{40 percent} = \frac{x}[/tex]

[tex]\frac{6,400,000}{40 percent} = \frac{x}[/tex]

Answer:

The amount after 8 years is $19249.17

Step-by-step explanation:

For any calculation for investments there si the compound interest formula:

[tex]A=P(1+\frac{r}{n} )^(n*t)[/tex]

Where

P = principal amount (the initial amount you borrow or deposit)

r  = annual rate of interest (as a decimal)

t  = number of years the amount is deposited or borrowed for.

A = amount of money accumulated after n years, including interest.

n  =  number of times the interest is compounded per year  

So for this example

P, the original amount ($14000)

r, 4%

t, 8 years

A, the amount after 8 years

n, 4, due that is quarterly

[tex]P=$14000(1+((4/100)/(4)))^(4*8)\\\\P= $19249.17[/tex]
