Alex buys 30 shares of Walmart at the close price if $48.80. His broker charges him 3% of each share. How much did Alex spend in total to buy this stock?

Answers

Alex spend $1507.92 in total to buy this stock at 3% charges on each shares.

What is shares?

Shares represent equity ownership in a corporation or financial asset, owned by investors who exchange capital in return for these units.

Alex buys 30 shares of Walmart at the close price of $48.80.

His broker charges him 3% of each share.

Purchasing of 30 shares =48.80 *30

                                         =$1464

Now we have to find the 3% of total purchasing of shares.

So,

Broker's fees =[tex]\frac{3}{100}*1464[/tex]

                      = 0.03 * 1464

                      = 43.92

So, total cost of stock= 1464+43.92

                                   = 1507.92

Hence, Alex spend $1507.92 in total to buy this stock.

Step-by-step explanation:

Find: E(XX1, , Xn), V(XX1, , Xn), E(X), V(X₂).

Law of total variance: V(X) = E(V(XY))+ (E(X|Y)).

Sample variance, i.e. s² = (X; - X)2 is an unbiased estimator of population variance.

Answers

The expected value of the assumed probability density function is 3/4 and the variance is 3/80

How to solve for E(x) and V(x)?

The probability density function is not properly stated.

So, I will provide a general explanation on how to determine E(x) and V(x) of a probability density function

Assume that the probability density function is given as:

[tex]f(x)= \left[\begin{array}{ccc}3x^2 &0 \le x \le 1\\0&Otherwise\end{array}\right[/tex]

The expression E(x) is calculated using:

[tex]E(x) = \int\limits^a_b {x \cdot f(x)} \, dx[/tex]

So, we have:

[tex]E(x) = \int\limits^1_0 {x \cdot 3x^2 \ d(x)[/tex]

Evaluate the product

[tex]E(x) = \int\limits^1_0 { 3x^3 \ d(x)[/tex]

Integrate

[tex]E(x) = \frac34x^4 |\limits^1_0[/tex]

Expand

[tex]E(x) = \frac34(1-0)^4[/tex]

Evaluate

[tex]E(x) = \frac34[/tex]

The variance is then calculated using:

[tex]Var(x) = E(x^2) - (E(x))^2[/tex]

Calculate [tex]E(x^2)[/tex] using:

[tex]E(x^2) = \int\limits^a_b {x^2 \cdot f(x)} \, dx[/tex]

This gives

[tex]E(x^2) = \int\limits^1_0 {x^2 \cdot 3x^2} \, dx[/tex]

Expand

[tex]E(x^2) = \int\limits^1_0 {3x^4} \, dx[/tex]

Integrate

[tex]E(x^2) = \frac{3}{5}x^5|\limits^1_0[/tex]

Expand

[tex]E(x^2) = \frac{3}{5}(1 - 0)^5[/tex]

Evaluate

[tex]E(x^2) = \frac{3}{5}[/tex]

Substitute [tex]E(x^2) = \frac{3}{5}[/tex] and [tex]E(x) = \frac34[/tex] in [tex]Var(x) = E(x^2) - (E(x))^2[/tex]

[tex]Var(x) = \frac 35 - (\frac{3}{4})^2[/tex]

Evaluate the exponent

[tex]Var(x) = \frac 35 - \frac{9}{16}[/tex]

Evaluate the difference

[tex]Var(x) = \frac{3}{80}[/tex]

Hence, the variance of the probability density function is 3/80

Patrick and Brooklyn are making decisions about their bank accounts. Patrick wants to deposit $300 as a principal amount, with an interest of 3% compounded quarterly. Brooklyn wants to deposit $300 as the principal amount, with an interest of 5% compounded monthly. Explain which method results in more money after 2 years. Show all work.

Answers

Answer:

Brooklyn's method results in more money after 2 years

Step-by-step explanation:

Compound Interest Formula

[tex]\large \text{$ \sf A=P(1+\frac{r}{n})^{nt} $}[/tex]

where:

A = final amountP = principal amountr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsed

Patrick's Method

Given:

P = $300r = 3% = 0.03n = 4t = 2

Substituting the given values into the formula and solving for A:

[tex]\implies \sf A=300\left(1+\dfrac{0.03}{4}\right)^{4 \times 2}[/tex]

[tex]\implies \sf A=300\left(1.0075\right)^{8}[/tex]

[tex]\implies \sf A=318.4796543...[/tex]

Therefore, using Patrick's method, there would be $318.48 in the account after 2 years.

Brooklyn's Method

Given:

P = $300r = 5% = 0.05n = 12t = 2

Substituting the given values into the formula and solving for A:

[tex]\implies \sf A=300\left(1+\dfrac{0.05}{12}\right)^{12 \times 2}[/tex]

[tex]\implies \sf A=331.4824007...[/tex]

Therefore, using Brooklyn's method, there would be $331.48 in the account after 2 years.

As $331.48 > $318.48 then Brooklyn's method results in more money after 2 years.

Answers

The tangent, cosine and sine ratios of angles X & Y in the reduced faction form is 3/4, 4/5 and 3/5 respectively.

What are the trigonometry ratios?

For a right angle triangle, the trigonometry ratios can be given as,

[tex]\rm \sin \theta=\dfrac{b}{c}\\\rm \cos \theta=\dfrac{a}{c}\\\rm \tan \theta=\dfrac{b}{a}[/tex]

Here, a is base side, b is perpendicular side and c is the hypotenuse side of the triangle.

In the given triangle, the length of base side is 8 units, perpendicular side is 6 units and hypotenuse side is 10 units.

[tex]a=8\\b=6\\c=10[/tex]

Thus, the  tangent, cosine and sine ratios of angles X & Y are,

[tex]\rm \sin \theta=\dfrac{6}{10}=\dfrac{3}{5}\\\rm \cos \theta=\dfrac{8}{10}=\dfrac{4}{5}\\\rm \tan \theta=\dfrac{6}{8}=\dfrac{3}{4}[/tex]

8.1. If x is the distance from P to the flagpole and h is the height of the flagpole, then

tan(53°) = h/x

tan(28°) = h/(x + 20)

Solve for the first equation for h in terms of x :

h = x tan(53°)

Substitute this into the second equation and solve for x :

tan(28°) = x tan(53°) / (x + 20)

(x + 20) tan(28°) = x tan(53°)

x tan(28°) + 20 tan(28°) = x tan(53°)

x (tan(28°) - tan(53°)) = -20 tan(28°)

x = 20 tan(28°) / (tan(53°) - tan(28°))

x ≈ 13.4 m

8.2. By the law of cosines,

BD² = 7² + 11² - 2 • 7 • 11 cos(110°)

⇒   BD = √(170 - 154 cos(110°))

⇒   BD ≈ 14.9 cm

and

BC² = BD² + 16² - 2 • BD • 16 cos(40°)

⇒   BC = √(426 - 154 cos(110°) - 32 cos(40°) √(170 - 154 cos(110°)))

⇒   BC ≈ 10.6 cm

Now use Heron's formula. If S is the semiperimeter of ∆ABD and S' is the semiperimeter of ∆BCD, i.e.

S = (AB + BD + AD)/2 ≈ 16.5 cm

S' = (BC + CD + BD)/2 ≈ 20.7 cm

then

area ∆ABD = √(S (S - AB) (S - BD) (S - AD)) ≈ 36.2 cm²

and

area ∆BCD = √(S' (S' - BC) (S' - CD) (S' - BD)) ≈ 76.7 cm²

so that the total area of ABCD is approximately 112.9 cm².

find the x-value where f attains it’s absolute maximum value on the closed interval x=-2 to x=6. justify your answer

Answers

Answer:

  x = -2

Step-by-step explanation:

The function is decreasing where the first derivative is negative.

That is, the function is decreasing on the interval (-2, 5), except at x=2, where there is a flat spot. That means the maximum value is found at the left end of that interval, at x=-2.

__

The maximum value might be found at x = 6, at the right end of the interval (5, 6) on which the function is increasing. However, we judge the area under the first derivative curve between x=5 and x=6 to be less than the total area under the curve between x=-2 and x=5. That means the function does not increase enough from its minimum at x=5 to make up for the decrease over the longer interval.

__

The attachment shows an approximation of the derivative function given in the problem statement (dashed line) and its integral (solid line). Not all of the curvature of f'(x) is accounted for in the approximation, but the overall result is consistent with the above analysis.

B. 3. 114 > 3. 112

This is true since in the thousandths place, 4 is greater than 2.

C. 4. 003 < 3. 996

This is clearly false, since in the whole part, 4 is greater than 3.

D. 0. 541 > 0. 145

This is true, since in the tenths place, 5 is greater than 1.
