Answer:
P(X=3cars) = 0.052
P(X>3 cars) = 0.00638
Step-by-step explanation:
In total there are 7 cars per hour.
Using formulae for geometric Probability
P(X=3) = (7^3×e-7)/3! = 0.0521
P(X>3cars) = (7^2× e-7)/2! =
P(X>3) = 0.0128/2×1 =0.00638
Answer:
7x = 35cm ; 2x = 10cm
Step-by-step explanation:
7x and 2x are the lengths
7x+2x=45
Then you take 7 + 2 = 9
so is gonna be 9x = 45
then you divide both side with 9
so is gonna be x = 5
Then you take 5 multiply 7 : 2
so 7 x 5 = 35cm
2 x 5 = 10cm
The answer is only I and II
By AAS congruency the two triangles are congruent
