Diagonals of a parallelogram bisect each other
or they intersect each other in the halfway
x+4=3y-11-------------------------equation1
2x-1=y-1-------------------------------equation2
mulitply equation 1 to 2
2x+8=6y-22-----------------------equation3
equation2 - equation3
-9=-5y +21
5y=30
y=6
then x= 3
now PT=2x-1=5
TR=y-1=5
ST=3y-11=7
TQ=x+4=3+4=7

Answer:
70.69
Step-by-step explanation:
Area =
Area =
Area = 70.68583471
<u>Area = 70.69</u>
Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
