A quality-control inspector is testing sample output from a production process for widgets wherein 95% of the items are satisfactory (S) and 5% are unsatisfactory (U). Three widgets are chosen randomly for inspection. The successive quality events may be assumed independent. Find the probabilities for the following numbers of unsatisfactory items:

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

the answer is 24

step-by-step explanation:

answer: 193

explanation:

200-7 = 193

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.
