Answer:

If a scatter plot shows a linear association, then there is a line that describes the relationship between the two measured quantities reasonably well. This means that there is a clear pattern in the data, and that the data points tend to follow a straight line when plotted on a graph. This does not necessarily mean that there is a line that passes through all of the plotted data points or that there is a tendency for relatively high values for one measured quantity to be paired with relatively high values for the other measured quantity.

<h3>Area of Compound Shapes</h3>

This exercise requires your knowledge about the area of compound shapes. For solving this, you should:

Identify the basic shapes;
Calculate your individual areas;
Sum each area found.

For finding the area, the steps are presented below.

STEP 1 - Identify the basic shapes.

This trapezoid is composed of two triangles and one rectangle. Therefore, you should sum the area of these geometric figures.

STEP 2 - Find the area of the triangle.

Area of the triangle - $A_{triangle}=\frac{b*h}{2}$ . The figure shows:

b= length of the base= 2in

h=height=9 in

Then, $A_{triangle}=\frac{b*h}{2}=\frac{2*9}{2} =\frac{18}{2}=9 in^2$

Note that the triangles are equals, consequently, they present the same values for the area.

STEP 3 - Find the area of the rectangle.

Area of the rectangle- $A_{rectangle}={b*h}$ . The figure shows:

b= length of the base= 12 in

h=height= 9in

Then, $A_{rectangle}={b*h}=12*9=108 in^2$ .

STEP 4 - Find the area of the trapezoid.

$A_{trapezoid}=2*A_{triangle}+1*A_{rectangle}\\ \\ A_{trapezoid}=2*9+1*108\\ \\ A_{trapezoid}=18+108\\ \\ A_{trapezoid}=126in^2$

8(x + 2) = 48<br> How do I solve this?

Rufina [12.5K]

You distribute the 8 to the x and the 2 which leaves you with 8x + 16 = 48 then u subtract the 16 on both sides, subtract 16 - 16 (cancel out) then 48-16 which gives you 32, from there you should have 8x=32 then you divide 8x by 8 and 32 by 8 which leave the x by itself and you 32/8 is 4 so the final answer is x = 4 !!

Rounding in the calculation of monthly interest rates is discouraged. Such rounding can lead to answers different from those pre

scZoUnD [109]

Step-by-step explanation:

Are you using a particular calculator for the class? For this class, is the payment expected to be compounded monthly?

There is a function in Microsoft Excel that will calculate the payment for you, but the answer is going to be slightly different for a business math class than a calculus-based statistics class.

The excel formula to calculate a payment is

=PMT(0.04/12,60,25000,0)

.04/12 is the interest APR on a monthly basis

60 is the number of months

25000 is the current amount owed

0 is the future balance after 60 payments

The answer from Excel is $460.41 -- ignore the negative sign for these purposes.

Multiply that number by the 60 months you pay and you get a total paid of $27,624.78

Remove the initial 25K and $2,624.78 is your interest amount.

By the way, I used the simplifying assumptions that the problem meant "interest rate" when it said "APR", and that the rate would compound monthly. In the actual loan industry, the interest rate is only part of the calculation for APR, a

146.08

Step-by-step explanation:

Let's start by figuring out the payment

effective rate: .035/12= .002916667

\begin{gathered}2000=x\frac{1-(1+.002916667)^{-48}}{.002916667}\\x=44.71\end{gathered}

2000=x

.002916667

1−(1+.002916667)

−48

x=44.71

then it's just

44.71*48-2000=146.08
