Answer:

5.5

Step-by-step explanation:

The <em>rate of change</em> of a relationship is the <em>ratio of corresponding changes in value</em>. Symbolically, we indicate a change with the greek letter Δ (pronounced "delta"). A <em>change in x</em> is written Δx ("delta eks") and a <em>change in y</em> is written Δy ("delta why"). We're looking for the ratio Δy/Δx ("delta y over delta eks").

Mathematically, Δx and Δy are the <em>differences</em> between two corresponding x an y values. To pick these, we can take any two rows in our table. Let's pick rows 4 and 2, nice whole numbers:

\Delta{x}=20-10=10\\\Delta{y}=112-57=55\\\Delta{y}/\Delta{x}=55/10=11/2=5.5

We can confirm that this holds for every other pair, too - picking rows 2 and 1 as an example:

\Delta{x}=10-5=5\\\Delta{y}=57-29.5=27.5\\\Delta{y}/\Delta{x}=27.5/5=275/50=11/2=5.5

Write the raito as a fraction simplest from 12 boys and 15 girls​
kiruha [24]

Step-by-step explanation: We can write a ratio using the word "to", using a colon, or using a fraction bar.

Here, since we want our ratio in simplest form,

I would use a fraction bar.

Now, the problem asks us to compare

the number of boys to the number of girls.

We know that there are 12 boys

and we know that there are 15 girls.

So our ratio is 12/15.

However, this can be reduced to 4/5.
