Step-by-step explanation:
Marvin invested 65% of his retirement account in stocks and 35% in gold. Marvin believes that the return to stocks over the next 12 months is normally distributed with mean rate of return of 10% and standard deviation of return of 15%. He also believes that the return to gold over the next 12 months is normally distributed with mean rate of return of 30% and standard deviation of return of 40%. Finally, Marvin believes that the return to stocks and the return to gold are independent.1. According to Marvin's beliefs, what are the mean rate of return and the standard deviation of return to his investment portfolio? 2. What is the probability that Marvin's portfolio will make at least 20% over the next 12 months? Show your work and explain. Write all the steps of your analysis and/or calculations so that it is clear how you reached your results.
Answer:
1)
the mean rate of return is 17 %
the standard deviation of return is 17.06055
2)
the probability that Marvin's portfolio will make at least 20% over the next 12 months is 0.4325
Step-by-step explanation:
Given the data in the question;
1)
For the portfolio, the mean return and standard deviation are computed as follows;
Mean = Return = 0.65 × 10 + 0.35 × 30
= 6.5 + 10.5
= 17 %
Therefore, the mean rate of return is 17 %
Standard deviation will be;
σp = √( 0.65² × 15² + 0.35² × 40² )
= √( 0.4225 × 225 + 0.1225 × 1600 )
= √( 95.0625 + 196 )
= √291.0625
= 17.06055
Therefore, the standard deviation of return is 17.06055
2)
probability that Marvin's portfolio will make at least 20% over the next 12 months.
P( X > 20 )
we convert to a standard normal variable;
Z = [tex]\frac{20-17}{17.06055}[/tex] )
Z = 0.17
from z table, p-value is;
p( X < 20 ) = 0.5675
P( X > 20 ) 1 - 0.5675 = 0.4325
Therefore, the probability that Marvin's portfolio will make at least 20% over the next 12 months is 0.4325

PLEASR HELP ASAP PRETTY EASY QUESTION JUST STUCK
Answer:
m1 is 36º and m2 is 54º
Step-by-step explanation:
So this looks like a 90º angle, just split up in two different other angles. This angle altogether is 90º.
So let's make an equation.
(x+18) + 3x = 90
Now just solve for x, you can get rid of the parenthesis.
x + 18 + 3x = 90
Combine the like terms first --
x + 3x = 4x
Now it is 18 + 4x = 90
Now to isolate 4x you have to subtract 18, so do it on both sides. 18-18=0 90-18= 72
Now the equation is 4x = 72
Now to isolate x you do opposite operation and divide 4x/4 and 72/4 = 18
So, x equals 18. Now you know what x is, you have to find out what m1 and m2 is. Replace x with 18.
m1-- 18 + 18 = 36
m2-- 3(18)= 54
So, m1 is 36º and m2 is 54º
Hope this helps!!

For what value(s) of k will the relation not be a function?
#1: A = {(k^2, 16), (4k, 32)}
#2: B = {(k^2-5k, 10), (k+7, 4)}
#3: R = {(k^3-5k^2+3k, -5), (-k, 4)}
#4: S = {(|k+1|+2, 4), (8, 7)}
Will give 100 points and Brainliest!
Answer:
See belowStep-by-step explanation:
The relation is not a function when x -value is same but y- values are different.
#1
k^2 = 4kk = 0, k = 4#2
k^2 - 5k = k + 7k^2 - 6k = 7k^2 - 6k + 9 = 16k - 3 = 4 ⇒ k = 7k - 3 = -4 ⇒ k = -1#3
k^3 - 5k^2 + 3k = -kk^3 - 5k^2 + 4k = 0k(k^2 - 5k + 4) = 0k = 0, k = 1, k = 4#4
|k + 1| + 2 = 8|k + 1| = 6k = 5, k = -7Select the statement that describes this expression: 5 x 3 − (2 x 4) + 5.
Answer:
It would be subtract the product of 2 and 4 from the product of 5 and 3, then add 5 because it’s parenthesis then you would multiply/devide then add/subtract whatever comes first

Holly wants to make a frame for a painting. The painting is square and has an area of 225 square inches. a. Write an equation to represent the area of the painting, using s for side length. Then, solve the equation for s. b. The framing material costs $1.35 per inch. How much will she spend?
Answer:
a) area = side²
225 in² = side²
side = √225 = 15 inches
b) 15 inches per side x 4 sides x $1.35 per inch = $81.00

A king size candy bars costs $1 with each candy bar having 1,500 calories. If you bought 6 candy bars and took 2 days eating them (eating the same amount each day) how many calories would you consume a day?
Answer:
4,500 calories a day
Step-by-step explanation:
If you ate the same amount each day, that means you would eat 3 a day, since 6 divided by 2 is 3.
Find how many calories you would eat each day by multiplying 3 by 1,500
3(1,500)
= 4500
So, you would eat 4,500 calories a day
