Answer:
1.4
Step-by-step explanation:
Given the probability distribution :
X _____ 0 ____1 ____ 2 ____ 3 ____4
P(x) _ 0.16 _ 0.41 _ 0.32 __ 0.09 __ 0.02
Expected number of people waiting in line :
E(X) = Σ(x * p(x))
E(X) = (0*0.16) + (1*0.41) + (2*0.32) + (3*0.09) + (4*0.02)
E(X) = 1.4
Answer: Divide the total kilometers covered by the number of hours the driver travels. This means you divide 2,380 km by 28 hrs. To find the average. Meaning the average speed is 85km/h.
Step-by-step explanation:
Take the total km the driver has traveled and divide it by the total hours they have driven to find your answer.
2,380 km /28 hrs = 85 km/h
Answer:
D
Step-by-step explanation:
If you knew some angles or if side y and the side thats 18 were parallel, then you could do some things, but I don't think theres enough information.
Answer:
1. ∠1 and ∠3. ∠1 and ∠2.
2. ∠6 and ∠5. ∠6 and ∠4
Step-by-step explanation:
Adjacent angles are two angles that have a common vertex but do not overlap. The ones above are the pairs of adjacent angles that share a common vertex, but do not overlap.
