Angle ADC is a linear pair ( 180° )
[tex] \angle \: ADC = \angle \: ADE + \angle BDE[/tex]
[tex]180 \degree = 112 \degree - \angle \: BDE [/tex]
[tex] \angle BDE = 180 - 112[/tex]
=> BDE = 68°
Similarly,
BCE is a linear pair or straight line.
BEC = BED + DEC
=> 180° = BED + 126°
=> BED = 180° - 126°
=> BED = 54°
As we know that Sum of angles of triangle is 180° .
m + 68° + 54° = 180°
=> m + 122 = 180°
=> m = 180° - 122°
=> m = 58°
The value of m is 58° .

In a right triangle, the ratio of the opposite side of one angle to the hypotenuse is called sine.
In this problem the side JK is the opposite side of angle JLK whose value is 63 degrees. The hypotenuse is JL whose value is 8.
So the sine ratio of angle JLK would be
sin L=JK/JL
Substituting the numerical values,
sin 63°=JK/8
This implies JK=sin 63°×8 from wich we will get the value of JK
So, this equation sin 63°=JK/8 will let us solve for jk and the answer is the third one.

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

solve for the variable. -2x + 6 = 14
Answers
Answer:
Step-by-step explanation:
-2x + 6 = 14
-2x = 8
x = -4
Answer:
[tex]x=-4[/tex]
Step-by-step explanation:
To solve for the variable x, we're going to isolate it.
First step is: Subtracting 6 by both sides:
[tex]-2x+6-6=14-6\\[/tex]
Notice how the +6 and the -6 cancel each other out. So we get:
[tex]-2x=8[/tex]
Second step is to divide both sides by -2:
[tex]\frac{-2}{-2} x=\frac{8}{-2}[/tex]
The -2's cancel each other out to:
[tex]x=-4[/tex]

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.
Answers
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
