The response time for ski patrol rescue responders is measured by the length of time from when the radio call is finished and when the responders locate the skier. Responders consider between 0 to 5 minutes as an ideal response time. Supposing gathered data showed a Normal distribution with a mean of 6 minutes and a standard deviation of 1.2 minutes, what percent of responses is considered ideal? Round to the nearest whole percent. Use a z-table to answer the question.

Step-by-step explanation: got it right

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.
