Money Mark makes for $3300, he invested = $363

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

It's given that Mark is investing his money. He thinks that he should make $11 for every $100 he invests.

Now by using the basic unitary method we can solve the problem as :

Money Mark makes for every $100 he makes = $11

Money Mark makes for every $1 he invested  = $ 11 / 100 = $0.11

Money Mark makes for $3300 he invested = 0.11 x 3300 = $363

Therefore, money Mark makes for $3300, he invested = $363

The system of equations 16 + 4 y + 5 x = 0 and - 48 - 12 y = - 9 x will have the solution as x = 0 and y = - 4.

We are given a system of equations as:

16 + 4 y + 5 x = 0    … (1)

- 48 - 12 y = - 9 x

- 16 - 4 y = - 9 x

9 x - 16 = 4 y   … (2)

Substitute the equation (2) in the equation (1), we get that:

16 + 9 x - 16 + 5 x = 0

14 x = 0

x = 0

4 y = 9 ( 0 ) - 16

4 y = - 16

y = - 16 / 4

y = - 4

Therefore, we get that, the system of equations 16 + 4 y + 5 x = 0 and - 48 - 12 y = - 9 x will have the solution as x = 0 and y = - 4.

Answer:

The standard deviation of the sampling distribution is [tex]\sigma =0.0087[/tex]

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  1500

     The population proportion is  [tex]p = 0.013[/tex]

Generally the standard deviation of this sampling distribution is mathematically represented as

      [tex]\sigma = \sqrt{ \frac{p (1- p)}{ n} }[/tex]

=>     [tex]\sigma = \sqrt{\frac{0.13(1-0.13)}{1500} }[/tex]

=>   [tex]\sigma =0.0087[/tex]

The standard deviation of the considered sampling distribution of the proportion supporting the increase is 0.0027 approx.

Suppose the sample proportion be denoted by [tex]\hat{p}[/tex], then, its distribution is normally distributed with mean [tex]p[/tex] and the standard deviation of distribution of [tex]\hat{p}[/tex] is given by

 [tex]\sigma = \sqrt{\dfrac{p(1-p)}{n}}[/tex]

where n is the sample size. It is true until [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

For the given case, we're given that:

Thus, standard deviation of the sampling distribution is approximately 0.0027

The total amount of money is 65x + 10 cents.

Given the following coins value

x dimes, (x+2) nickels, and 2x quarters

If value of a dime is 10 cents, nickel is 5 cents, and a quarter is 25 cent, the the total coin is cent is expressed as 10x + 5(x + 2) + 25(2x)

Total in cents. = 10x + 5(x + 2) + 25(2x)

Total in cents = 10x + 5x + 10 + 50x

Simplify

Total in cents = 65x + 10

If, on the other hand, the balance is growing exponentially, f(x)=800(1+0.13)x where x represents the number of months, what would the balance be after 34.9 months is: $56,954.45.

Using the given exponential to determine what would the balance be after 34.9 months.

f(x)=800(1+0.13)x

Where:

x=number of months

Hence:

f(x)=800(1+0.13)x

f(x)=800(1+0.13)^34.9

f(x)=800(1.13)^34.9

f(x)=800(71.19306287)

f(x)= $56,954.45

Therefore if, on the other hand, the balance is growing exponentially, f(x)=800(1+0.13)x where x represents the number of months, what would the balance be after 34.9 months is: $56,954.45.

Read the excerpt from The Crisis, Number I by Thomas Paine.

“I once felt all that kind of anger, which a man ought to feel, against the mean principles that are held by the Tories: a noted one, who kept a tavern at Amboy, was standing at his door, with as pretty a child in his hand, about eight or nine years old, as I ever saw, and after speaking his mind as freely as he thought was prudent, finished with this unfatherly expression, ‘Well! give me peace in my day.’ Not a man lives on the continent but fully believes that a separation must some time or other finally take place, and a generous parent should have said, ‘If there must be trouble, let it be in my day, that my child may have peace;’ and this single reflection, well applied, is sufficient to awaken every man to duty.”

Which is a central idea of this excerpt?

Paine feels that everyone should be able to speak freely, which is why he supports independence.

Paine believes that colonists should fight for independence so their children can live in peace.

Paine believes that some people are selfish and place their needs above others.

Paine felt anger for the first time when he saw an interaction between a Tory and a child.

Answer:

c. (10.1, 15.7)

Step-by-step explanation:

The calculation of the 95% confidence interval is shown below:

Given that

n = sample = 14

average = [tex]\bar x[/tex] = 12.9

Standard deviation = s = 4.9

Based on the above information

[tex]\alpha = 1 -0.95 = 0.05[/tex]

n - 1 = 14 - 1 = 13

[tex]t_{\alpha}\ value = 2.16[/tex]

Now the 95% confidence interval is

[tex]= \bar x + \pm\ t \times \frac{s}{\sqrt{n} } \\\\= 12.9 \pm 2.16 \times \frac{4.9}{\sqrt{14} } \\\\= 12.9 \pm 2.8287[/tex]

= (10.1, 15.7)

hence, the correct option is c.
