Answer:

Step-by-step explanation:

It is given that, in Russia there are 21 rocket launch failures out of 743 total launches. We need to find no of failures for the next 800 launches.

21 rocket = 743 launches

1 launch = $\dfrac{21}{743}\ \text{failures}$

For 800 launches,

$=\dfrac{21}{743}\ \text{failures}\times 800\\\\=22.611\ \text{failures}$

= 23 failures

So, there are 23 failures in next 800 launches.

Are the ratios 25/45 and 15/27 proportional? Explain.

liberstina [14]

Write them out as a fraction then reduce them. If theyre the same then its proportional.

25/45 can be cancelled down to 5/9

15/27 can be cancelled down to 3/9

So no theyre not.
