Answer:

The percent error is 40%

Step-by-step explanation:

To calculate the error percentage we have to divide the final amount over the initial amount

350 / 250 = 1.4

then we subtract 1 since this represents the estimated value

1.4 - 1 = 0.4

this is the error factor we have, to express it as a percentage we simply multiply by 100

0.4 * 100 = 40%

The percent error is 40%

Simplify completely quantity 4 x squared minus 32 x plus 48 all over quantity 3 x squared minus 17 x minus 6. (1 point)
Galina-37 [17]

Given rational expression is:


\frac{(4x^2-32x+48)}{(3x^2-17x-6)}

Now we can simplify this by factoring as shown below:


=\frac{4(x^2-8x+12)}{(3x^2-17x-6)}


=\frac{4(x-2)\left(x-6\right)}{(3x^2-18x+1x-6)}


=\frac{4(x-2)\left(x-6\right)}{3x\left(x-6\right)+1\left(x-6\right)}


=\frac{4(x-2)\left(x-6\right)}{(3x+1)\left(x-6\right)}


=\frac{4(x-2)}{(3x+1)}



Hence final answer is \frac{4(x-2)}{(3x+1)}

he dot plot shows the number of words students spelled correctly on a pre-test. A number line going from 2 to 11. 0 dots are abo
Klio2033 [76]
<h3>Answer: B. Graph is nearly symmetrical</h3>

Explanation:

Given information:

  • A number line going from 2 to 11.  
  • 0 dots are above 2.  
  • 0 dots are above 3.  
  • 1 dot is above 4.  
  • 2 dots are above 5.  
  • 4 dots are above 6.  
  • 4 dots are above 7.  
  • 3 dots are above 8.  
  • 2 dots are above 9.  
  • 2 dots are above 10.  
  • 0 dots are above 11.

From that we can see the data set is {4,5,5,6,6,6,6,7,7,7,7,8,8,8,9,9,10,10} which produces the dot plot you see in the image attachment below.

It's a bit tricky to see, but the graph is nearly symmetrical. If we were to remove the blue points in the dot plot I provided, then we'll get a perfectly symmetrical distribution. Symmetrical means one half is a mirror copy of the the other half. The center line of a symmetrical distribution is both the mean and median.
