6 0

The correct matches are:

Birds - A

Dinosaurs - B

Amphibians - C

Corals - D

Trilobites - E

By the statements presented, we have the situation where the trilobites are the oldest of the species, thus they will be on the bottom layer. The corals are second ones that emerged, so they will be found in the second bottom layer, and after them come the amphibians that will be found in the third layer. The dinosaurs evolved after the amphibians, so since they are younger than them, they will be located in the second layer from the top, with the birds evolving from the later dinosaurs and being the youngest, they will be found in the top layer.

In a survey of employee satisfaction, 60% of the employees are male and 45% of the employees are satisfied. What is the probabil
melamori03 [73]

Answer:

The probability of being a male and a satisfied employee is 27%

Explanation:

The probability of being a male P(m) = 60% = 60/100 = 0.6

The probability of being a satisfied employee P(s) = 45% = 45/100 = 0.45

Mathematically, the probability of being a male and satisfied = Probability of being a male * Probability of being a satisfied employee = P(m) * P(s) = 0.6 * 0.45 = 0.27

or simply 27/100 which is same as 27%
