A system has two components, Component 1 and Component 2, with reliabilities of 0.7 and 0.85 respectively. In order for the system to work, both components have to work. Component 1 has a switch and the switch needs to function in order for Component 1 to work. The switch has a reliability of 0.9. In addition, Component 2 is connected to a backup component, Component 3, with a reliability of 0.84. What is the reliability of the whole system

4096 bacteria

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
