Determine whether QR is parallel to ST

Mathematics
1 answer:
arlik [135]3 years ago
3 0

Answer:

The correct answer is: 3. QR ∦ ST    4. QR ║ ST

Step-by-step explanation:

If the PST and PQR triangles are similar, then the corresponding sides are proportional. We will check that:

PS : PQ = PT : PR  ⇔ PS / PQ = PT / PR = k

3.

10/4 = 8/3 => 5/2 = 8/3

When we multiply the both fractions to get same denominators we get

15/6 ≠ 16/6

the corresponding sides are not proportional and triangles PST and PQR are not similar and QR ∦ ST => QR is not parallel to ST

4.  27/22 = 43.2/35.2 = 1.2272727.... = 1.2(27)

the corresponding sides are proportional and triangles PST and PQR are similar and QR ║ ST => QR is parallel to ST

God with you!!!

As a rule of thumb, the sampling distribution of the sample proportion can be approximated by a normal probability distribution
netineya [11]

As a rule of thumb, when each component is selected independently from the same population, the sampling distribution of the sample percentage may be estimated by a regular probability distribution.

<h2>Why is it crucial to use the thumb rule?</h2>
  • One of our primary, simple-to-learn ways to handle complexity is the rule of thumb. Real thumb rules take into account operating, security, and financial constraints.
  • They inform us of the likely location of a practical solution. Additionally, they reveal which tactics are most prone to failure.
<h3>What is sampling distribution?</h3>
  • A statistic that is obtained by sampled data from a bigger population is known as a sampling distribution.
  • It depicts an array of potential results that may result from a statistic, such as the mean or mode of a certain parameter because there is really a population.

Therefore the main solution is- from the identical group, each component is individually chosen.
