1. D - Since it's random, everyone has an equal chance of being picked

2. B - Since the people are already registered voters it would be easier to get a response from them. Plus, picking ever 10th person makes it random.

3. false - a fair question wouldn't make assumptions about the population

4. B - "Don't you think" causes the answerer to be pushed towards saying yes

hope this helps :)

Henry buys a large boat for the summer, however he cannot pay the full amount of $32,000 at

Anna007 [38]

Answer:

Monthly payments=$418.14

Total amount will be=down payment + 48×$418.14

$14000+$20070.84=$34070.84

Step-by-step explanation:

Loan payment per month=Amount to pay÷discount factor

Mathematically P=A÷D

where D is the discount factor calculated using the formula;

$\frac{(1+i)^n-1}{i(1+i)^n}$

where i=periodic interest rate=annual rate divided by number of payment periods

A is the amount to pay after downpayment

P is the loan monthly payment amount

n=number of periodic payments=payments per year times number of years

⇒In this question you find the discount factor then divide the amount remaining to pay with the discount factor to get monthly payments

Given;

Cost of boat=$32000

Down payment=$14000

Loan to pay=$32000-$14000=$18000

Annual rate=5.5%=i=5.5%÷12=0.458%⇒0.00458

Periodic payments, n=4×12=48

Finding the discount factor D;

$D=\frac{(1+i)^n-1}{i(1+i)^n} \\\\\\D=\frac{(1+0.00458)^{48} -1}{0.00458(1+0.00458)^{48} } \\\\\\D=\frac{1.2455-1}{0.005703} \\\\\\D=\frac{0.2455}{0.005703} =43.05$

To get the amount to pay monthly divide the loan to pay with the discount factor

$=\frac{18000}{43.05} =418.14$

Monthly payments=$418.14

Total amount will be=down payment + 48×$418.14

$14000+$20070.84=$34070.84

The number of exports is shown as g(x). Use the data in the table below, representing both functions, to explain to your boss th

siniylev [52]

Step-by-step explanation:

Given the table:

Month f(x) = Number of imports g(x) = Number of exports

January (1) 3 1

February (2) 4 3

March (3) 5 5

April (4) 6 7

From the table, it is clear that:

Number of imports = number of month + 2

$f(x) = x + 2$

also

Number of exports = 2(number of month) + 1

$g(x) = 2x - 1$

Therefore, number of imports equals the number of month plus one. i.e. $f(x) = x + 2$ , which is a linear function.

If we compare it with slope-intercept form of the line

$y=mx+b$

Then,

slope = m = 1

y-intercept = 2

Also number of exports equals is also a linear function.

i.e. $g(x) = 2x - 1$

Here,

slope = m = 2

y-intercept = -1

Solve system of equations<br><img src="https://tex.z-dn.net/?f=x%20%2B%202y%20-%20z%20%3D%204%20%5C%5C%202x%20-%20y%20%2B%203z%2

Natasha2012 [34]

First, using elimination method for eq. 1 and 2 to eliminate one of the variables.

2x - y + 3z = 8

-2x + 3y - 2z = 10

------------------------------

2y + z = 18

z = 18 - 2y

Now eq. 1 and 3, but multiple eq.1 with 2.

2x + 4y - 2z = 8

-2x + 3y - 2z = 10

----------------------------

7y - 4z = 18

Now you have two new equations 7y -4z = 18 and z = 18 - 2y. Solve for y and z, using substitute method.

7y - 4z = 18

7y - 4(18 - 2y) = 18

7y - 72 + 8y = 18

15y = 18+72

y = 90/15

y = 6

Find z using one of the two new equations.

z = 18 - 2y

z = 18 - 2(6)

z = 18 - 12

z = 6

Now you got y and z, find x using any one of the main three equations.

x + 2y - z = 4

X + 2(6) - 6 = 4

x + 12 - 6 = 4

x = 4 - 6

x = -2

Solutions:

x = -2

y = 6

z = 6

A box can be filled completely using 9 layers of 11 units cubes. What is the volume of the box?

mote1985 [20]

The volume of the box is 99 unit cubes.

<h3>What is the volume of the box?
</h3>

A cube is a three-dimensional object that has six faces, twelve edges and eight vertices. The length, width and height of a cube usually has equal dimensions. The volume of the box is a function of the dimension of the cubes in it and the number of layers.

Volume of a box = number of layers x amount of units

9 x 11 - 99 unit cubes
