Use a proportion to estimate each population. (Please solve both questions, thank you) (I’ll reward you with brainliest :)
hammer [34]

Answer:

<em>Step-by-step explanation:</em>

<em>Step 1. (The capture) Capture a sample  total counted =958, and them back tagged counted=38,total tagged=56 </em>

<em>The idea is to estimate the proportion p = m/N of tagged =102. </em>

<em>Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged. </em>

<em>It is reasonable that, k/n would be a good estimante for p = m/N. </em>

<em>Accordingly, for an estimate N of N, se solve the equation m/N= k/n. </em>

You cut off half of a strip of paper. then you cut half of the piece was left. then you cut half of the remaining piece.
lianna [129]

Answer:

The fraction of the original strip left is \frac{1}{8}.

Step-by-step explanation:

We have that,

A strip of paper is cut in \frac{1}{2}. So, the strip of paper left is \frac{1}{2}.

Now, again the remaining part is cut in half. The part left will be  \frac{1/2}{2} i.e.  \frac{1}{4}.

Finally, the remaining part is again cut in half.

We get, the final part of the paper remaining is  \frac{1/4}{2} i.e.  \frac{1}{8}.

So, the fraction of the original strip left is \frac{1}{8}.

Oduvanchick [21]

The angle RAT which is made with AR and AT line and shown in the figure of protector, measures 30 degrees.

<h3>How to measure the angle in protector?</h3>

Protector is the most useful device to measure the angle between two lines. To measure the angle between two lines using the protector following steps is followed:

  • Place the protector center point at the vertex of unknown angle.
  • One side of angle should be place at 0 mark line of this device.
  • Other side of angle will be equal to the angle shown in protector on that line.

In the given figure, The angle Between AR and AT line is 30 degrees shown in protector.

Thus, the angle RAT which is made with AR and AT line and shown in the figure of protector, measures 30 degrees.
