Soloha48 [4]

Answer:

7 females, 24 males

Step-by-step explanation:

I solved it by using this equation:

2x + 17 = 31

then, i subtracted 17 on both sides:

2x=14

then divide by 2 on both sides:

x=7

then I added 7 to 17 to find the number of males:

7+17= 24

<h3>The absolute error is 6</h3><h3>The percent error is 16.22 %</h3>

<em><u>Solution:</u></em>

Given that,

Actual volume of his bathtub is 37 gal

Estimate is 31 gal

<em><u>Find the absolute error</u></em>

Absolute Error = | Measured Value - Actual Value |

Absolute Error = | 31 - 37 |

Absolute Error = 6

<em><u>Find the percent error</u></em>

Percent\ error = \frac{\text{estimate - actual}}{actual} \times 100

Substituting we get,

percent\ error = \frac{31-37}{37} \times 100\\\\percent\ error = \frac{-6}{37} \times 100\\\\percent\ error = -16.22

Negative sign means percent decrease

Thus percent error is 16.22 %
