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.

(a) Let X₁, X denote a bootstrap sample and let X = n
Find: E(XX1, , Xn), V(XX1, , Xn), E(X), V(X₂).
Hint: Law of total expectation: E(X)= E(E(XY)).
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

John is making apple pies and apple cobblers to sell at the farmer’s market. A pie uses 4 cups of apples and 3 cups of flour. A cobbler uses 2 cups of apples and 3 cups of flour. When John sells the pies and cobblers at the farmer’s market, he will make $3.00 profit per pie and $2.00 profit per cobbler. Let x = the number of pies John makes. Let y = the number of cobblers John makes. Interpret the meaning of the vertex with the maximum profit in context of john’s baking.
Answers
Step-by-step explanation:
there are some pieces of information missing like the price of apples and flour. or the selling prices. or any restrictions like a fixed budget to buy ingredients or how many pies and cobblers he can make in a certain available time.
all we can say based on the given information :
one pie = 4a + 3f (a = apples, f = flour)
one cobbler = 2a + 3f
P(x, y) = 3x + 2y =
= x(selling price - 4a - 3f) + y(selling price - 2a - 3f)
the max. of P(x, y) is the maximum profit by selling pies and cobblers, which is without any further information +infinity.
the more pies and cobblers he sells, the bigger the profit - no limit.

Answers
Answer:
B. 3.114 > 3.112
D. 0.541 > 0.145
E. 0.141 < 0.19
Step-by-step explanation:
In order to determine which decimal is greater or less than another, compare the place values from left to right. First, compare the whole numbers to the left of the decimal point. If they are not the same, the smaller decimal number is the one with the smaller whole number. This applies to the rest of the places.
----------------------------------------------------
32.3 has a greater tenths value than 32.03, so 32.03 < 32.3. Option A is false.
----------------------------------------------------
3.114 has a greater thousandths value than 3.112, so 3.114 > 3.112. Option B is true.
----------------------------------------------------
4.003 has a greater whole number than 3.996, so 4.003 > 3.996. Option C is false.
----------------------------------------------------
0.541 has a greater tenths value than 0.145, so 0.541 > 0.145. Option D is true.
----------------------------------------------------
0.19 has a greater hundredths value than 0.141, so 0.141 < 0.19. Option E is true.
hope this helps!
The inequalities which are truly compared are B, D and E.
Given certain inequalities.
We have to find the true comparisons.
We have to look at the corresponding digits of numbers which are compared from left to right. Greater numbers on the left will be the greater number.
A. 32. 03 > 32. 3
This is false since 32.3 is greater. In 32.03, 0 is in the tenth place, while 3 is in the tenth place for 32.3.
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.
E. 0. 141 < 0. 19
This is also true, since in the hundredths place, 9 is greater than 4.
Hence the true comparisons are B, D and E.

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 elapsedPatrick's Method
Given:
P = $300r = 3% = 0.03n = 4t = 2Substituting 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 = 2Substituting 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.
The figure below shows the graph of f’ the derivative of the function f, on the closed interval from x = -2 to x = 6. The graph of the derivative has horizontal tangent lines at x = 2 and x = 4.
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.
