That is false. When you look at a number line, -3 is to the left of -2. A number to the left of another number is less than the number to the right.

find the absolute error and percentage error in rounding; the yearly profit of $1367540 made by a company to $1.37 million

Savatey [412]

Answer:

0.18%

Step-by-step explanation:

% error= accepted value - experimental value/ accepted value

Step 1: subtract one value from another

1,367,540-1,370,00=-2460

Depending on what you need it you may take away the negative sign

Step 2: So your absolute error is equal to 2,460

Step 3: divide error by true value

= 2460/1,370,000

Ans = 0.0018

Step 4: multiply this value by 100% to obtain the percent error

0.0018 X 100% = 0.18%

what is an equation of a line that passes through the point (-4,-6) and is perpendicular to the line 2x-y=6

igor_vitrenko [27]

Answer:

Answer:y=2/3x-10/3

- 4/-6 is 4/6 so m is 4/6 then fill in the x and y variables in y=Mx+b solve for b then start plotting the equation of the line to check and you get your answer

I think this is the answer you might need to check again with more people

Use the number line to represent. -4 1/2 + 3 1/4. what is the sum?

dlinn [17]

Answer:

$\displaystyle A+B=-\frac{5}{4}$

Step-by-step explanation:

<u>The Number Line</u>

Let's call

$\displaystyle A=-4\frac{1}{2}$

$\displaystyle B=+3\frac{1}{4}$

Both numbers are given as mixed fractions. Let's convert them to improper fractions:

$\displaystyle A=-4\frac{1}{2}=-(4+\frac{1}{2})=-\frac{8+1}{2}=-\frac{9}{2}$

$\displaystyle B=3\frac{1}{4}=3+\frac{1}{4}=\frac{12+1}{4}=\frac{13}{4}$

The decimal values are A = -9/2=-4.5, B=13/4 = 3.25

Now represent the points in the number line. See the image below

Finally, calculate their sum:

$\displaystyle A+B=-\frac{9}{2}+\frac{13}{4}$

$\displaystyle A+B=-\frac{18}{4}+\frac{13}{4}=\frac{-18+13}{4}$

$\boxed{\displaystyle A+B=-\frac{5}{4}}$

You rilll a number cube. How likely is it that you will roll a number less than 1? Less than 7?

Andrews [41]

Less than 1 would be a 0% chance because there is not a number smaller than 1 on a die. Less than 7 would be 100% chance because all of the numbers on a die are less than 7.
