Step-by-step explanation:

Answer: q=210

Step-by-step explanation:

For this question you have to do the inverse to 'undo' the equation.

So, instead of taking away 89 you have to add it to 121.

q=121+89

q=210

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]

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

Step-by-step explanation:

tanФ=   [tex]\frac{1}{2\sqrt{2} } =\frac{2\sqrt{2}}{8} =\frac{\sqrt{2} }{2}[/tex]

cscФ=   [tex]3[/tex]

Answer:

i know this isn't the answer but this should help...

Step-by-step explanation:

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.

Step-by-step explanation:

Answer: Step 1 box= 19 (2+3+4+5+5)

Step 2 box= 3.8 (19 divided by 5)

Step-by-step explanation:

You add together the numbers to get 19, the you divide the number by five because you added 5 numbers together.

You had it just right on the bottom. Your equation was perfect. It doesn't matter if you get a decimal number.

Your answers are right too, I double checked.

Answer:

10.2

Step-by-step explanation:

The B of years it took to the given principal to amount $910 is 3.4 years.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, principal =$750, rate of interest =1.9% and amount=$910.

Let the number of years be x and compounded quarterly.

Here, 910=750(1+ 1.9/100)³ˣ

910/750 =(1+0.019)³ˣ

1.213=(1.019)³ˣ

Take the logarithm of both sides of the equation to remove the variable from the exponent.

Exact Form:

x=ln(1.213)/3ln(1.019)

Decimal Form: 3.419

≈ 3.4 years

Therefore, the number of years it took to principal to reach $910 is 3.4 years.
