Answer:
Given vertices of the triangle ABC,
A(-4,-2), B(-1,3), and C(5,0),
A) By graphing,
The vertices of preimage of the vertices of A, B and C are shown as below.
B) Since, the rule of 180°counterclockwise about the origin,
If the triangle ABC is rotated 180°counterclockwise about the origin to form triangle A′B′C′.
The vertices of A'B'C' are,
A'(4,2), B'(1, -3), C'(-5,0)

Answer:
The point estimate for population mean is 8.129 Mpa.
Step-by-step explanation:
We are given the following in the question:
Data on flexural strength(MPa) for concrete beams of a certain type:
11.8, 7.7, 6.5, 6.8, 9.7, 6.8, 7.3, 7.9, 9.7, 8.7, 8.1, 8.5, 6.3, 7.0, 7.3, 7.4, 5.3, 9.0, 8.1, 11.3, 6.3, 7.2, 7.7, 7.8, 11.6, 10.7, 7.0
a) Point estimate of the mean value of strength for the conceptual population of all beams manufactured
We use the sample mean, as the point estimate for population mean.
Formula:
Thus, the point estimate for population mean is 8.129 Mpa.
