Answer:

95 percent confidence interval

[0.208,0.29166]

Step-by-step explanation:

First we identificate the sample proportion p = 27 /108, and we find the 95 percent confidence interval for P(population proportion) in this context the parking violations that have prior unpaid parking tickets.

Then α = 0.05 and 1 - α/2 = 0.975

Thus $Z_{0.975} = 1.96$

The 95 percent confidence interval is

[ p ± 1.96 $\sqrt{\frac{p(1-p)}{n} }$ ]

[0.25 ± 1.96 $\sqrt{\frac{0.25*0.75}{108} }$ ]

[0.208,0.29166]

The statements below can be used to prove that the triangles are similar. ? △ABC ~ △XYZ by the SSS similarity theorem. Which mat

Vsevolod [243]

Solution:

It is given that two triangles Δ ABC and Δ X Y Z are similar by Side -Side - Side(SSS) Similarity theorem.

So, the Statement which is given, that is →→∠B ≅ ∠Y and ∠B ≅ ∠Z, is inadequate for similarity criterion by SSS, as these statement are about angles of Triangles,not sides, which can't be true.

So, if the two triangles are Similar by SSS criterion , then the appropriate mathematical statement must be,

⇒ $\frac{AB}{XY}=\frac{BC}{ZY}=\frac{AC}{XZ}$
