Are the answers these below?

A. The scale is accurate but not precise.

B. The scale is precise but not accurate.

C. The scale is neither precise nor accurate.

D. The scale is both accurate and precise.

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

Then you need to tell the difference between accuracy and precision.

Accuracy refers to the closeness of the measure to the real value, while precision, in this case, refers to the level of significant figures that the sacle report.

The fact that the scale reports the number with 4 significant figures means that it is very precise, but the fact that the result is not so close to the real value as the number of significan figures pretend to be, means that the scale is not accurate.

So, the answer is that

B. The scale is precise but not accurate

This shows that Billy will have $12, 168.25 after 12 years

<h3>Compound interest</h3>

The formula for calculating the compound interest is expressed as:

$A = P(1+r/n)^{nt}$

From the information given, the amount is expressed as;

$A = 8000(1+0.035/12)^{12(12)}\\A= |\$12,168.25$

This shows that Billy will have $12, 168.25 after 12 years

Table of inches and centimeters

TEA [102]

If you compare table values to answer choices, you can see right away that several don't work. The number of centimeters is greater than the number of inches, so adding to or multiplying the number of centimeters by some number more than 1 will not give you the smalller number that is inches.

While it may work for the first number (5 inches) to add 7.7 to get the first number of centimeters (12.7), you have to know that you can only add like to like. You can only add inches to inches (getting a result of inches), or centimeters to centimeters (getting a result of centimeters). From the point of view of the units involved, it is nonsensical to add a pure number to a number of inches and expect to get a number of centimeters.

So, we're down to the second choice:

- The number of inches is multiplied by 2.54 to find the number of centimeters.

_____

To find the pattern in the table, you can ...

observe that the inch values differ by 1
observe that the centimeter values differ by 2.54
realize that the constant differences mean the relation between inches and centimeters is linear, and that a change in an inch value of 1 inch is multiplied by 2.54 to find the corresponding change in centimeter value.

_____

I don't know what the first step in your problem solving process is supposed to be. In my problem solving process, the first step is always to look at what you are given. The next step is look at what you are being asked for.

Could somebody please help me with this?

BARSIC [14]

For this problem, we are going to use the Remainder Theorem. This says that for $x - n$ to be a factor of a polynomial $p(x)$ , then $p(n) = 0$ . Essentially, it says that $x - n$ is a factor if when you substitute $n$ into the polynomial you get a result of 0.

Thus, in our case, when we substitute $x = 2$ into the polynomial, we should get an answer of 0 if $x - 2$ is a factor of the polynomial. Given this information, we can solve for $c$ :
