Answer:
Option d. PQ = YZ
Step-by-step explanation:
<u><em>The question in English is</em></u>
Choose the most appropriate answer. The PQR triangle and the XYZ triangle are two congruent triangles. The angle P = the angle Y and PR = YX. Side pairs of the same length are ... a. PQ = XZ b. QR = YZ c. QR = XY d. PQ = YZ
we know that
If two triangles are congruent, then its corresponding sides and its corresponding angles are congruent
Corresponding sides are named using pairs of letters in the same position on either side of the congruence statement
so
we have that
so
Triangle PQR is congruent with Triangle YZX
That means
<em><u>Corresponding angles</u></em>
<u><em>Corresponding sides</em></u>
Answer:
As per the statement:
Let Event A represents the probability that a vehicle is white and Event B represents the probability that it is a pick up truck .
then;
and
It is also given that:
The Probability that it is a white pick up truck is 0.06.
⇒ where
represents that it is white pick up truck.
We have to find the the probability that the vehicle is white {given that the vehicle is a pickup truck}
We use the formula:
where
represents that the pick up truck vehicle is white.
Substitute the given values we get;
Therefore, the probability that the vehicle is white, given that the vehicle is a pickup truck is 0.4
