5 0

Answer:

-7

Step-by-step explanation:

Seems like the pattern is adding and then subtracting the next square number up:

7 + 4 = 11

11 - 9 = 2

2 + 16 = 18

so 18 - 25 = -7 is the next number

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}

A dilation is an enlargement if the scale factor is _____ between 0 and 1. greater than 1. less than 0. equal to 1.
boyakko [2]

Dilation is one of the several means by which we can transform a graph. A function is dilated when is stretched away from an axis or compressed towards an axis. So this means there are 2 types of dilation: a) Stretch (Enlargement) and b) Compression.

Depending on the direction of Dilation, we have Horizontal Dilation and Vertical Dilation.

For a function y = f(x), horizontal dilation is achieved when x is replaced by \frac{x}{A} and vertical dilation is achieved when y is replaced by \frac{y}{A} where A is the scale factor.

In each of these cases, the function will be stretched if |A| > 1 and will be compressed if |A| < 1.

Therefore, the answer to the given question is:

A dilation is an enlargement if the scale factor is greater than 1.
