This means that 2n is equal to or greater than -1 +10 or -1-10, which can be shown as 2n ≥ 9 and 2n ≥-11, and since 2n ≥11 encompasses both, we can therefore say  2n ≥-11 or n ≥ -5.5 by dividing both sides by 2

podryga [215]

The fraction of the girls signed up to play outfield is \frac{2}{15}

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

Given that Two fifths of the girls in school signed up to play softball

An equal number of girls signed up to play pitcher, infield and outfield

So there are 3 equal groups formed from two fifth

This means that we could divide the 2/5 initial group into 3 equal smaller groups for each play pitcher, infield and outfield

Therefore, fraction of the girls signed up to play outfield is found by dividing \frac{2}{5} by 3

\text{ Fraction of girls play outfield } = \frac{\frac{2}{5}}{3}\\\\\text{ Fraction of girls play outfield } = \frac{2}{5} \times \frac{1}{3}\\\\\text{ Fraction of girls play outfield } = \frac{2}{15}

Thus fraction of the girls signed up to play outfield is \frac{2}{15}
