Answer:
0.75
Step-by-step explanation:
Given that there is a 50% chance that it will rain today and a 50% chance that it will rain tomorrow
We find that these two events are independent
A = rains today and B = rains tomorrow
A and B are independent
So we have
P(AB) =P(A)P(B)
the probability that it rains at least one of the days
= P(A or B) =P(A)+P(B)-P(AB)
=0.5+0.5-0.5(0.5)
=0.75
Answer:
When a shape is transformed by rigid transformation, the sides lengths and angles remain unchanged.
Rigid transformation justifies the SAS congruence theorem by keeping the side lengths and angle, after transformation.
Assume two sides of a triangle are:
And the angle between the two sides is:
When the triangle is transformed by a rigid transformation (such as translation, rotation or reflection), the corresponding side lengths and angle would be:
Notice that the sides and angles do not change.
Hence, rigid transformation justifies the SAS congruence theorem by keeping the side lengths and angle, after transformation.
