Identify the reflection rule on a coordinate plane that verifies that triangle A(-1,7), B(6,5), C(-2,2) and A'(-1,-7), B'(6,-5),
malfutka [58]

Answer:

Option B is correct.

The reflection rule is followed here is,  (x,y) \rightarrow (x, -y).

Explanation:

Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.

A(-1,7) \rightarrow A'(-1,-7)

B(6,5) \rightarrow B'(6,-5)

C(-2,2) \rightarrow C'(-2,-2)

Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is, (x,y) \rightarrow (x, -y)

Determine the probability of rolling a number that is not even.
lapo4ka [179]

Answer:

\frac{1}{2} or 0.5 or 50%

Step-by-step explanation:

P(not even) = P(odd) = P(1) or P(3) or P(5) = P(1) + P(3) + P(5)

= \frac{1}{6}+ \frac{1}{6}+\frac{1}{6} = \frac{3}{6}= \frac{1}{2}

Alternatively

P(not even) = 1 -P(even) = 1 - [P(2) or P(4) or P(6)]

= 1 - [ \frac{1}{6}+ \frac{1}{6}+\frac{1}{6}] = 1 - \frac{3}{6} = \frac{1}{2}
