Answers

Answer:

194.

Step-by-step explanation:

x = (7+4√3)

x^2 =  x = (7+4√3)^2

= 49 + 48 + 56√3

= 97 + 56√3

x^2 + 1/x^2 =    97 + 56√3 + 1/(97 + 56√3)

= 194.

A jewelry supply shop buys silver chains from a manufacturer for c dollars each, and then sells the chains at a 57-percent markup. Write the markup as a decimal, A expression for the retail price silver chain, a retail price of a silver chain purchased for 45 dollars, and how much was added to the original price of the chain

( if you answer all the questions i will mark you the Brainy-est. )

Answers

The amount added to the original price of the jewelery is the Markup price. Hence, the amount added is $16.34

Markup = 57% = 0.57Cost of jewellery = cRetail price = $45

Retail price = cost of jewellery + Markup

$45 = c + 0.57c

45 = 1.57c

Divide both sides by 1.57

c = 45/1.57

c = $28.66

The Markup price = (Retail price - Original price)

Markup = $45 - $28.66 = $16.34

Therefore, the amount added to the original price is $16.34

A college student takes out a $7 500 loan from a bank. Assuming the student has not started paying back the money, how much does the student owe . . .

1.1 . . . after 1 year, if the bank charges 3.8% interest each year?

Answers

The key to these questions is to understand the compounding. In this case, they are telling you the banks compound annually.

So the time period in the compounding equation is YEARS.

The compounding equation is:


(Future Loan Amount) = (Current Loan Amount) * (1 + the interest rate of the time period in decimals) ^ (number of time periods)


(Use this for all future questions too - if compounding monthly then time period is total number of months and interest rate is annual rate divided by 12 etc)


So in this case the answer is:


(Future Loan Amount) = (Current Loan Amount) * (1 + the interest rate of the time period in decimals) ^ (number of time periods)


(Future Loan Amount) = $7,500 * (1 + 0.038) ^ (11) = $11,304


(note - when answering its hard to see the original question. I believe the answer asked for 11 years. If not, if 1 year, etc just plug in that number into the equation - so one year is simply: 7500*1.038 = $7,785

inverse variation

=========================================================

We divide both sides by x to isolate y. That's how we go from xy = 7 to y = 7/x

This is an inverse variation because it's in the form y = k/x. The constant is k = 7.

Step-by-step explanation:

The SAT is the most widely used college admission exam. (Most community colleges do not require students to take this exam.) The mean SAT math score varies by state and by year, so the value of µ depends on the state and the year. But let’s assume that the shape and spread of the distribution of individual SAT math scores in each state is the same each year. More specifically, assume that individual SAT math scores consistently have a normal distribution with a standard deviation of 100. An educational researcher wants to estimate the mean SAT math score (μ) for his state this year. The researcher chooses a random sample of 656 exams in his state. The sample mean for the test is 480.

Find the 95% confidence interval to estimate the mean SAT math score in this state for this year.

(Note: The critical
z
-value to use,
z
c
, is: 1.960.)

( , )

Answers

Using the z-distribution, it is found that the 95% confidence interval to estimate the mean SAT math score in this state for this year is (472, 488).

We have the standard deviation for the population, which is why the z-distribution is used to solve this question.

The sample mean is [tex]\overline{x} = 480[/tex].The population standard deviation is [tex]\sigma = 100[/tex].The sample size is [tex]n = 656[/tex].

The interval is given by:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

We have to find the critical value, which is z with a p-value of [tex]\frac{1 + \alpha}{2}[/tex], in which [tex]\alpha[/tex] is the confidence level.

In this problem, [tex]\alpha = 0.95[/tex], thus, z with a p-value of [tex]\frac{1 + 0.95}{2} = 0.975[/tex], which means that it is z = 1.96.

Then:

[tex]\overline{x} - z\frac{\sigma}{\sqrt{n}} = 480 - 1.96\frac{100}{\sqrt{656}} = 472[/tex]

[tex]\overline{x} + z\frac{\sigma}{\sqrt{n}} = 480 + 1.96\frac{100}{\sqrt{656}} = 488[/tex]

The 95% confidence interval to estimate the mean SAT math score in this state for this year is (472, 488).
