Answer:

<em>624 is the answer</em>

Step-by-step explanation:

5x²-3x+5 x=2

plug in x=2: 25²-6+5=?

do the 25²: (25*25=625)

plug in 625 into the equation: 625-6+5

subtract 6 from 625: 625- 6= 619

plug 619 into your equation: 619+5=?

add 5 to 619: 619+5= 624

Ava estimates that 475 songs will fit on her iPad. The actual amount of songs that fit is 350. Find her percent of error.

Given:

Ava estimates that 475 songs will fit on her iPad.

The actual amount of songs that fit is 350.

To find:

The percent of error.

Solution:

We know that,

$\text{Percent error}=\dfrac{\text{Estimated values - Actual value}}{\text{Actual value}}\times 100$

Putting the given values, we get

$\text{Percent error}=\dfrac{475-350}{350}\times 100$

$\text{Percent error}=\dfrac{125}{350}\times 100$

$\text{Percent error}=\dfrac{250}{7}$

$\text{Percent error}\approx 35.71\%$

Therefore, the percent of error is 35.71%.
