Answer:
28.63%
Step-by-step explanation:
Given data:
correlation between funds = 0.308
Risk-free rate = 0.042
Expected return rate = 0.11
Calculate the standard deviation of the new portfolio
standard deviation of portfolio = ( weight of risky assets )* (standard deviation of optimal risky portfolio )
weight of risky assets = (expected return - risk-free rate) / ( expected return of optimal portfolio - risk-free rate ) ( calculated using excel spreadsheet)
= 0.9696
Standard deviation of optimal risky portfolio = 29.525489% ( calculated using excel spreadsheet )
hence standard deviation of portfolio that would an expected return of 11%
= 0.9696 * 29.525489%
= 28.63%

how much money is six dimes worth???
Answer: 60 cents
Step-by-step explanation: 1 Dime= 10 cents; 10x6= 60.
Answer: 60 cents.
Step-by-step explanation:
One dime is worth 10 cents. Therefore, if you have six of them it's simple repeated addition
10+10+10+10+10+10
or simple multiplication.
10(6)
Which are both the same exact thing.
So six dimes are 60 cents. Hope that helps!!

This needs to be answered for a number line
-9=4x+3
Answer:
X=-3
Step-by-step explanation:
To find the unknown variable: X, we need to see how mich 4x equals to. to do this, we must first subtract 3 from both sides of the equation. The left side will be left with -12, and the right side will be left with 4x. This means:
-12=4x So...
x=-3
To check if this is right, you can subsitute this back into the equation.
4 times -3= -12. -12=3=-9

this my explanation.N entry level technical writer's annual pay is $55,068 based on 52 weeks per year. Due to the economy, his company is having to cut back on the number of weeks that it employs its technical writers. If the firm cuts the work year to 51 weeks but keeps the same rate of pay, how much should the technical writer expect his annual pay to decrease? Round your answer to the nearest dollar.
Answer:
The technical writer should expect his annual pay to decrease by $1,059
Step-by-step explanation:
52 weeks = $55,068
51 weeks =
Cross Multiply
51 weeks × $55,068/52 weeks
= $54009
The writer will be paid $54009 for 51 weeks
His pay reduced by:
$55,068 - $54,009
= $1,059

A least squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. The line is weight = -5.58 + 0.1686 length. A newborn was 48cm long and weighed 3 kg. According to the regression model, what was his residual? What does that say about him?
1) WHAT WAS HIS RESIDUAL?
2) WHAT DOES THAT SAY ABOUT HIM? SELECT THE CORRECT CHOICE AND FILL IN ANY ANSWER BOXES TO COMPLETE YOUR ANSWER (round to three decimal places as needed)
a. the newborn weighs ____ kg less than the weight predicted by the regression equation
b. the newborn weighs _____ kg more than the weight predicted by the regression equation
c. the newborn weighs the same as the weight predicted by the regression equation
Answer:
0.487 kg
b.) the newborn weighs 0.487kg more than the weight predicted by the regression equation
Step-by-step explanation:
Given the Regression equation:
Weight = - 5.58 + 0.1686 length
Length of newborn = 48 cm
Actual Weight of newborn = 3kg
Predicted weight from regression model:
Weight = - 5.58 + 0.1686(48)
Predicted Weight = 2.513kg
Hence, residual = (Actual - predicted)
Residual = (3kg - 2.513kg) = 0.487kg
Since the actual weight is more or greater than the predicted weight:
b.) the newborn weighs 0.487kg more than the weight predicted by the regression equation

. Mr. Lorenzo gave his 2 sons $50 to buy a cooler. The total cost for the cooler is $44. Mr. Lorenzo told his sons that they could each have an equal share of the change they receive. The equation shown can be used to determine s, the amount of money each son should receive in dollars. S = (50 - 44) 2 What amount of money is represented by s ?
Answer:
S=$3Step-by-step explanation:
Given that the cost of cooler is $44
money given to the two sons $50
let S represent the amount the two son will have to share equally
the change is 50-44=6
=$6
Then s=6/2=$3
applying with the expression directly we have
S = (50 - 44)/2
S = (6)/2
S=$3

John's wants to open a bank account with $100. He will have to pay a service fee of $5 per month to keep it open. Let y represent the amount of money in his account and x represent the number of months.
Answer:
y+5x
Step-by-step explanation:
Y is the start so you have to add that to the amount of money total for all of the months and to get the total of the months you have to multiply 5 by the number of months he had the account open
Una tableta contiene 500 mg de paracetamol, ¿cuántas tabletas se obtendrán con 5kg del mismo medicamento? xfavor ayudenme con explicación y todo lo necesito para el sabado
Answer:
Se pueden obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad de 5 kg del medicamento
Step-by-step explanation:
La cantidad en masa de paracetamol en una tableta = 500 mg de paracetamol / tableta
El número de comprimidos que contienen 500 mg de paracetamol que se pueden obtener a partir de 5 kg del medicamento (paracetamol) se calcula dividiendo los 5 kg del medicamento por los 500 mg de paracetamol / comprimido de la siguiente manera;
[tex]El \ nmero \ de \ tableta = \dfrac{5 \ kg \ paracetamol}{500 \ mg \ paracetamol/tableta }[/tex]
Observamos que 5 kg = 5,000,000 mg
Por lo tanto;
[tex]El \ numero \ de \ tableta = \dfrac{5,000,000 \ mg \ paracetamol}{500 \ mg \ paracetamol/tableta } = 10,000 \ tabletas[/tex]
Por tanto, podemos obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad dada de 5 kg del medicamento.
Which of the following is true about the lines defined by the equations 4x−2y=6 and x+2y=14? .
A.The lines share the same y-intercept.
B.Both lines intersect at point (1,−1).
C.The lines are perpendicular.
D.The lines are parallel.
Answer:
Only: C. The lines are perpendicular.Step-by-step explanation:
4x - 2y = 6 x + 2y = 14
- 2y = - 4x + 6 2y = - x + 14
y = 2x - 3 y = - ¹/₂x + 7
A.
y-intecept: (0, -3) (0, 7)
The lines don't share the same y-intercept
B.
x=1 ⇒ y = 2(1)-3 = -1 and y = -¹/₂(1) + 7 = 6¹/₂ ≠ -1
the line x+2y=14 doesn't go through point (1,−1) so the lines couldn't intersect at point (1,−1)
Slope: m₁ = 2 m₂ = -¹/₂
C.
m₁· m₂ = 2·(-¹/₂) = -1
The lines are perpendicular.
D.
m₁ ≠ m₂ The lines are not parallel

2. A package delivery service has a truck that can hold 4200 pounds of cargo
and has a capacity of 480 cubic feet. The service handles two types of
packages: small, which weigh up to 25 pounds each and are no more than 3
cubic feet each; and large, which are 50 pounds each and are 5 cubic feet
each. The delivery service charges $5 for each small package and $8 for each
large package. Let x be the number of small packages and y be the number of
large packages in the truck. What is the maximum revenue per truck?
Answer:
$680
Step-by-step explanation:
Capacity of the truck: 4200 pounds and 480 cubic feet of cargo.
Small package: 25 pounds and 3 cubic feet each.
Large package: 50 pounds and 5 cubic feet each.
For x number of small packages:
25x pounds and 3x cubic feet
Let x = 8,
200 pounds and 24 cubic feet.
For y number of large packages:
50y pounds and 5y cubic feet
Let y = 80,
4000 pounds and 400 cubic feet.
Since delivery service charges $5 for each small package and $8 for each large package.
The maximum revenue per truck = ($5x + $8y)
= ( $5 x 8) + ($8 x 80)
= $680
