Quadrilateral RJFT is similar to quadrilateral SYPA . JF=60 mm , AP=40 mm , and YP=25 mm . What is TF ?
Hoochie [10]
The two quadrilaterals are similar. Which means the ratios of respective sides of two quadrilaterals will be the same. 

So, for the given quadrilaterals, ratio of sides JF and TF of quadrilateral RJFT will be equal to the ratio of sides YP and AP of quadrilateral SYPA. Mathematically, we can write:

JF:TF = YP:AP \\  \\ &#10; \frac{JF}{TF} = \frac{YP}{AP}  \\  \\ &#10; \frac{60}{TF} = \frac{25}{40}  \\  \\ &#10;60* \frac{40}{25}=TF \\  \\ &#10;TF=96mm

So the measure of TF will be 96mm

in 2012, the general social survey included a question that asked participants how many hours they worked a week. do males work
Agata [3.3K]

Using sampling concepts, it is found that this is an example of independent samples.

  • For dependent samples, there is a paired measurement for one set of items.
  • For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.

In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.
