apter 5 – Finance – The first part of this review will explain the different interest and

investment equations you learned in section 5.1 through 5.4 of your textbook and go through

several examples. The second part of this review will give you various sample problems to work

on – you should know how to do all these sample problems for Exam II. The sample exam is

posted to the Math 113 webpage – please come to the Math Resource Center if you need help!

The sum of money you deposit into a savings account or borrow from a bank is called the

principal. The fee to borrow money is called interest. When you borrow money you pay back

the principal and interest to your lender. When you deposit money into a savings account or

other investment, the bank pays you back the principal and the interest earned. Interest is

calculated as a percent of the money borrowed, a percent of the principal. Depending on the type

of loan, interest can be calculated in a variety of ways.

Simple Interest Loans (Section 5.1) :

Simple Interest involves a single payment and the interest computed on the principal only. The

equation for simple interest is a linear function. If the problem refers to a simple interest rate,

then you know you need to use simple interest rate formulas.

Equation #1:

:

Pr

where

I = t

I = the amount of interest paid for borrowing the money

P= the principal or the amount of money you borrowed from the bank

r = is the simple interest rate – this is a per annum rate (i.e. yearly)

t = the amount of time the money is borrowed for – this needs to be in years if the problem gives

you t in months then you need to divide the number of months by 12 to convert t into years.

Equation #2:

A = (P+Prt)=P*(1+rt)

where:

A = the future value - the total amount the borrower owes at the end of the loan period – this is

Principal plus Interest.

I = the amount of interest paid for borrowing the money

P= the principal or the amount of money you borrowed from the bank

r = is the simple interest rate – this is a per annum rate (i.e. yearly)

t = the amount of time the money is borrowed for – this needs to be in years if the problem gives

you t in months then you need to divide the number of months by 12 to convert t into years.

Equation #3:

I = A – P

where:

A = the total amount you owe at the end of the loan period – this is Principal plus Interest.

I = the amount of interest paid for borrowing the money

i was doing jlabs lol

Answer:

1.6+3 x 4 -2/2

1.6+12-2/2

1.6+12-1

13.6-1

12.6

hope this helps

have a good day :)

Step-by-step explanation:

The expression 1.6 + 3 x 4 - 2 divided by 2  simplifies to 12.6.

Use the concept of mathematical expression defined as:

Using operations like addition, subtraction, multiplication, and division, a mathematical expression is defined as a group of numerical variables and functions.

The given expression is:

1.6 + 3 x 4 - 2 divided by 2

We know the BODMAS rule,

According to this rule for a mathematical expression, we have to follow these operations in the following order:

1: Bracket opening

2: Division

3: Multiplication

4: Addition

5: Subtraction

Now applying this rule in the given expression,

1.  1.6 + 3 x 4 - 1

2. 1.6 + 12 - 1

3. 13.6 - 1

4. 12.6

Hence,

The expression 1.6 + 3 x 4 - 2 divided by 2  simplifies to 12.6.

I love riddles, thank you!

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.

Since a total of 47 hats where purchased,  hence:

x + y + z = 47    (1)

Also, he spent a total of $302, hence:

5.5x + 6y + 7z = 302     (2)

He purchases three times as many medium hats as small hats, hence:

y = 3x

-x + 3y = 0    (3)

Represent equations 1, 2 and 3 in matrix form gives:

[tex]\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] ^{-1} \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}6\\18\\23\end{array}\right][/tex]

Therefore he purchases 6 small hats, 18 medium hats and 23 large hats

Answer:

Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.

Since a total of 47 hats where purchased,  hence:

x + y + z = 47    (1)

Also, he spent a total of $302, hence:

5.5x + 6y + 7z = 302     (2)

He purchases three times as many medium hats as small hats, hence:

y = 3x

-x + 3y = 0    (3)

Therefore he purchases 6 small hats, 18 medium hats and 23 large hats

Answer:

Step-by-step explanation:

Property of the perpendicular lines,

If the two lines [tex]L_1[/tex] and [tex]L_2[/tex] having slopes [tex]m_1[/tex] and [tex]m_2[/tex] are perpendicular to each other,

Then [tex]m_1\times m_2=-1[/tex]

Equation of line [tex]L_1[/tex] → y = 3x + 5 ------(1)

Equation of line [tex]L_2[/tex] → 6y + 2x = 1 ------- (2)

Slope of line [tex]L_1[/tex],

[tex]m_1=3[/tex]

Slope of line [tex]L_2[/tex],

6y + 2x = 1

6y = -2x + 1

[tex]y=-\frac{2}{6}x+\frac{1}{6}[/tex]

[tex]y=-\frac{1}{3}x+\frac{1}{6}[/tex]

Therefore, [tex]m_2=-\frac{1}{3}[/tex]

By using the property of perpendicular lines,

[tex]m_1\times m_2=3\times (-\frac{1}{3} )[/tex]

              [tex]=-1[/tex]

Therefore, both the lines are perpendicular.

Answer:

If you're timed then I would say,

Yes this is a random study because the problem specifically states that the survey samples were randomly selected from populations.

I think that is the answer! However, if you have time I would wait for another person to answer as well because I'm terrible at statistics :(

Answer:

No, its nat a random sample

Step-by-step explanation:

Its not a random sample because you have already selected two populations (the two largest US cities) which may or may not be representative of the vast majority of the country.
