Answer:
1:2
Step-by-step explanation:
Ratio of Perimeters = Ratio of sides
HELP/TRAP = HP/TP = 2/4 = ½
1:2
We can use the tangent function to find the value of angle C.
tan ∠C = 29/38
tan ∠C = <span>0.76315789473
Now we will do inverse of tangent on both sides.
</span>∠C ≈ 37°

Step-by-step explanation:
We are given the following information in the question:
X: 0 1 2 3 4
P(x): 0.4521 0.3970 0.1307 0.0191 0.0010
Formula:


Formula:


The standard deviation of given probability distribution is 0.767.
This tells us nothing there has to be other numbers unless they want 3ab
