Hi i needa gf im 16 im a kind loving caring person anyone 13 through 17

What minimum value of ma will keep the system from starting to move?

Andreyy89

Answer:

Explanation:

Block on the table m(A) = m1,

block on the cord m2,

the coefficient of static friction is k1=0.4,

the coefficient of kinetic friction is k2 =0.28

(a)

Block A:

T = F(fr) = k1 •N = k(s) • m1 •g,

Block B: T = m2•g.

k1 • m1 •g= m2•g,

m1 = m2/k(s) = m2/0.4.

(b)

Block A:

T = F(fr) = k2 •N = k2 • m1 •g,

Block B:

T = m2•g.

k2• m1 •g= m2•g,

m1 = m2/k2 = m2/0.28.

A survey of 50 retail stores revealed that the average price of a microwave was $375 with a sample standard deviation of $20. As

ohaa [14]

Answer:

True cost of the microwave is in 99% confidence interval: $c. $323.40 to $426.60$

Explanation:

Relevant data:

$n=50\\\mu=375\\\sigma=20\\\alpha=0,001$

As we want to know the 99% confidence interval, the significance level is:

$(1-\alpha).100\%=99\%\\1-\alpha=0.99\\\alpha=0.01$

We need to estimate a confidence interval by a two tailed normal bell. Then we have:

$Z_{\alpha/2}=Z_{0.005}$

The z-value for a probability of 0.005 in a normal standard distribution is 2.576

Confidence interval is given by;:

$\=x\±Z_{\alpha/2}\sigma\\375\±Z_{\0.005}(20)\\375\±(2.58)(20)\\375\±51.60$

$375+51.60=426.60\\375-51.60=323.40$

True cost of the microwave is in 99% confidence interval: $c. $323.40 to $426.60$

Your client, Bo Regard, holds a complete portfolio that consists of a portfolio of risky assets (P) and T-Bills. The information

kondaur [170]

Answer:

The expected return on Bo's complete portfolio will be "10.32%".

Explanation:

The given question is incomplete. Please find attachment of the complete question.

According to the question, the given values are:

Port's expected return,

$R_p=12 \ percent$

T-bill's expected return,

$R_t=3.6 \ percent$

Port's weight,

$W_p=80 \ percent \ i.e.,\ 0.80$

T-bill's weight,

$W_t=20 \ percent \ i.e., \ 0.20$

Now,

The Bo's complete portfolio's expected return will be:

⇒ $W_p\times R_p+W_t\times R_t$

On substituting the given values, we get

⇒ $0.80\times 12 \ percent+0.20\times 3.6 \ percent$

⇒ $10.32 \ percent$

Note: percent = %

If real income rises from $5 trillion to $6 trillion while the price level increases by 10 percent, it follows that nominal inco

AVprozaik [17]

The nominal income will increase with the increase in the real income.

<u>Explanation:</u>

Real income of the person is the buying or the purchasing capacity of the person. It is the nominal income adjusted for inflation. If there is an increase in the real income more than the increase in the level of the prices at a particular period of time, it means that the level of nominal income of the person will also increase.

A finance company has a total of $20 million earmarked for homeowner and auto loans. On the average, homeowner loans have a 10%

serg [7]

Answer:

Housing million dollars $1,655.2

Automobile million dollars $413.80

Explanation:

Calculation to determine the total amount of loans of each type

Calculation for HOMEOWNER LOANS

Homeowner loans=$20,000-[(10%*20,000)/(4*12%+10%)]*10%

Homeowner loans=[$20,000-($2,000/48%+10%)]*10%

Homeowner loans=[$20,000-($2,000/58%)]*10%

Homeowner loans=[$20,000-$3,448.3]*10%

Homeowner loans=$16,552*10%

Homeowner loans=$1,655.2

Calculation for AUTO LOANS

Auto Loans=[(10%*20,000)/(4*12%+10%)]*12%

Auto Loans=($2,000/(48%+10%)]*12%

Auto Loans=($2,000/58%)*12%

Auto Loans= $3,448.3*12%

Auto Loans=$413.80

Based on the above calculation Homeowner loans amount of $1,655.2 is 4 times Auto Loans amount of $413.80

Therefore the total amount of loans of each type that Madison should extend to each category in order to maximize its returns are:

Housing million dollars $1,655.2

Automobile million dollars $413.80
