Given,

Samantha invested $660 into an account that paid 3.5% interest compounded annually.

We need to find the total amount of interest paid by this investment at the end of 5 years

A=P(1+rt)

A is the final amount

P is the principal amount

r is the rate of interest

t is time

A=?,P=660,r=3.5%=0.035, t=5

A=660(1+0.035(5))

=660(1+0.175)

=660(1.175)

A=775.5

To check the total amount of interest paid by this investment at the end of 5 years

We need to find the difference between the initial amount and the final amount

775.5-660 =115.5

Hence 115.5  is the total amount of interest paid by this investment at the end of 5 years

The previous population of the city is 62500

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 3x + 4y = 14, 5x − 4y = 4.

if the previous population is represented by x and the increment by y, then

y= x×28/100

y = 28x/100 equation 1

the new population = previous population+ increment

therefore x+y= 80,000

represent 28x/100 for y in equation 2

x+28x/100= 80000

making the LHS a single fraction

(100x+28x)/100= 80000

128x= 80000×100

The expected value of your third punch is 5660.

What is probability?

A linear scale from 0 (impossibility) to 1 (certainty) or as a percentage between 0 and 100% expresses the likelihood that a specific event (or series of events) will occur.

Given that,

This is the third and last punch and also there is no removal of prizes after each punch. Hence, the expected value would be equal to the mean of all the possibilities available.

E(third punch) = Σ  x  p(x)

=  100× (5/50) + 250 × (10/50) + 500 × (10/50) + 1000 × (10/50) + 2500 ×(8/50) + 5000 × (4/50)     + 100000 × (2/50) + 25000 × (1/50)

=  5660

Let us find the median of the given possibilities,

5 100's, 10 250's, 10 500's, 10 1000's, 8 2500's, 4 5000's, 2 100000's, 1 25000

There is a total of 50 possibilities and hence the median will be the average of the 25th and 26th terms.

25th term = 500

26th term = 1000

Median = (500 + 1000) / 2 = 750

The next available possibility greater than 750 is 1000.

Probability of getting more than 1000 in third punch = P (x > 1000) = (No. of terms greater than 1000) / Total no. of possible outcomes                                                                                                         = 15 / 50 = 0.3

Probability of getting less than 1000 in third punch = P (x > 1000) = (No. of terms lesser than 1000) / Total no. of possible outcomes                                                                                                                

= 25 / 50 = 0.5

Hence, in the second chance of punch, 1000 or anything greater than 1000 is preferred because the probability of getting more than 1000 in the next chance is less than the probability of getting less than 1000.

The polynomial f(c)=4x^3+19x^2-58x+35 as a product of linear factors is f(c)=(x-1)(x+7)(4x-5)

To express the polynomial as a product of linear factors we have to find the zeros of the polynomial.

Here,

We have Given that f(c)=4x^3+19x^2-58x+35 and -7 is a zero of f(k) and we need to find the polynomial f(c)=4x^3+19x^2-58x+35 as a product of linear factor

Now,

-7 is a zero of f(k)

i.e. (x+7) is a linear factor of f(k)

now,

we will find out the linear factor of f(c)

so,

f(c)=4x^3+19x^2-58x+35

f(c)=4x^3-4x^2+23x^2-23x-35x+35

f(c)=(x-1)(4x^2+23x-35)

f(c)=(x-1)(4x^2+28x-5x-35)

f(c)=(x-1)(4x(x+7)-5(x+7))

f(c)=(x-1)(x+7)(4x-5)

Hence,

The polynomial f(c)=4x^3+19x^2-58x+35 as a product of linear factor is f(c)=(x-1)(x+7)(4x-5)

Thus,

the linear factor of given polynomial is (x-1)(x+7)(4x-5)

Answer:

The costs are equal at 3 miles.  It coest $8 for either company

At 8 miles the green cost 13 and the red cost 18.

My advice would be to use the Red compnay if traveling less than 3 miles and the green company is traveling more than 3 miels.  At 3 miles the costs are the same.

Step-by-step explanation:

The dimensions that will minimize the cost, obtained from the cost function are;

Width = [tex]\sqrt[3]{\frac{45}{11} }[/tex] feet

Length = [tex]2\cdot \sqrt[3]{\frac{45}{11} }[/tex] feet

Height = [tex]\dfrac{20}{\left(\sqrt[3]{\frac{45}{11} }\right)^2 }[/tex]

A function is a rule, or law or expression that provides the definition between an input variable and an output variable.

Base length of the box = 2 × The base width of the box

Cost of the material used to build the top and the bottom = $11 per square feet

Cost of the material used to build the sides = $3 per square feet

Volume of the box = 40 cubic feet

Let x represent the width of the base of the box, and let y represent the height of the box

The information from the question indicates;

The length of the base of the box = 2·x

The volume of the box, V = x × 2·x × y = 2·x²·y = 40

V = 2·x²·y = 40

[tex]y = \dfrac{40}{2\cdot x^2} = \dfrac{20}{x^2}[/tex]

The cost of the box which can be obtained from the surface area of the box can be found as follows;

Cost of the top and the bottom = 2 × x × 2·x × 11 = 44·x²

Cost of the material for the sides = (2 × x × y + 2 × 2·x × y) × 3 = 18·x·y

Cost of the box, C = 44·x² + 18·x·y

[tex]C = 44\cdot x^2 + 18\cdot x \times \dfrac{20}{x^2} = \dfrac{44\cdot x^2+360}{x}[/tex]

To minimize the cost of the box, we get;

[tex]C' =\dfrac{d}{dx}\left( \dfrac{44\cdot x^2+360}{x}\right) = 0[/tex]

[tex]\dfrac{d}{dx}\left( \dfrac{44\cdot x^3+360}{x}\right) = \dfrac{x\times 44\times 3 \times x^2 - \left(44\times x^3+360\right)}{x^2} = \dfrac{88\cdot x^3-360}{x^2} =0[/tex]

At the minimum cost, [tex]\dfrac{88\cdot x^3-360}{x^2} =0[/tex]

Therefore; 88·x³ - 360 = 0

88·x³ = 360

[tex]x = \sqrt[3]{\dfrac{360}{88} } =\sqrt[3]{\dfrac{45}{11} }[/tex]

The width of the base of the box that minimizes the cost is; [tex]x =\sqrt[3]{\dfrac{45}{11}}[/tex]

The length of the base of the box that minimizes the cost is; [tex]2\cdot x =2\times \sqrt[3]{\dfrac{45}{11}}[/tex]

The height of the box that minimizes the cost is; [tex]\dfrac{20}{x^2} = \dfrac{20}{\sqrt[3]{\dfrac{45}{11} } }[/tex]

The polynomial function with -3 as a zero of multiplicity 3 and 0 as a zero of multiplicity 1 will be x³+9x²+16x.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

It is given that the polynomial is given with -3 as a zero of multiplicity 3 and 0 as a zero of multiplicity 1.

Each zero, such as a, corresponds to a linear factor, such as (x a). The repeating of such components is corresponding to multiplicity. The following polynomial thus meets the requirements in our example:

= (x-(-3))³(x-0)¹

=(x³-3x²(-3)+3x(-3)²-(-3)²)(x)

=x³+9x²+27x-9x

Extreme values that significantly deviate from the dataset's or graph's normal distribution are known as outliers.

An outlier, to put it simply, is a data point in a data graph or dataset you're dealing with that is abnormally high or abnormally low in comparison to the nearest data point and the rest of the nearby coexisting values.

The vocabulary term is explained as,

1.Outlier - Extreme values that significantly deviate from the dataset's or graph's normal distribution are known as outliers.

2. Cluster - An identifiable cluster of values in a numerical variable's distribution that is close to one another and appears notably more frequently than values on either side of them.

3. Positive linear association - When the variable on the x-axis grows as the variable on the y-axis increases, a positive linear connection exists. An upward-sloping linear regression line demonstrates this.\

4. Negative linear association - A negative linear correlation exists when one variable rises while the other falls. An upwardly sloping straight regression line illustrates this.

5.No association - There is a "negative correlation" when one variable rises while the other one falls. The points in the scatterplot have no connection if there is no correlation between the variables.

6. Non-linear association - When two variables have a nonlinear relationship, the slope of the curve illustrating the relationship alters when the value of one of the variables varies. Any curve whose slope alters when one of the variables' values changes is said to be nonlinear.

Thus, extreme values that significantly deviate from the dataset's or graph's normal distribution are known as outliers.

Answer:

1,200 pennies

Step-by-step explanation:

The slopes and the y-intercepts of two equations are different.

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

From the information provided, we have the following equations:

2x + y = 3       ....equation 1.

−2y = 14 − 6x    ....equation 2.

In slope-intercept form, the first equation can be written by subtracting 2x from both sides as follows:

2x + y - 2x = 3 - 2x

y = 3 - 2x

y = -2x + 3

Therefore, m = -2 and c = 3.

For the second equation, we would divide both sides by -2 as follows:

−2y/-2 = 14/-2 − 6x/-2

y = -7 + 3x

y = 3x - 7

Therefore, m = 3 and c = -7.

In this context, we can reasonably and logically deduce that the slopes and the y-intercepts are quite different.
