well they could make a test they have to past for those who want to e officers.
Answer:
Step-by-step explanation:
PS and RS are tangents to the circle with center T at points P and R. (given)
TP and TR are radii of the given circle.
(radius is perpendicular to the tangent)
In quadrilateral SPTR
By inscribed angle theorem:
Answer:
Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles
Part B) The width of the river is about
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
Part A) we know that
In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent
so
-----> by vertical angles
-----> is a right angle
-----> the sum of the internal angles must be equal to 180 degrees
Part B) we know that
The triangles ABC and EDC are similar -------> see Part A
therefore
substitute the values and solve for AB
Answer:
Option D is correct, Wilcoxon signed rank test
Step-by-step explanation:
This will be a dependent sample because same students are being surveyed. Hence,
We should use Wilcoxon signed rank test <em><u>(which is a non-parametric statistical hypothesis test utilized to evaluate two related or connected samples, matched samples, or repetitive measurements on a lone sample to evaluate whether their population mean ranks differ.)
</u></em>
<em><u>
</u></em>
Option D is correct. Wilcoxon signed rank test.
