Meg travels often and lately has become lax about giving herself enough time to get to the airport. She leaves home 45 minutes before the last call for her flight. Her travel time from her front door to the airport parking lot is normally distributed with a mean of 25 minutes and a standard deviation of 3 minutes. From the parking lot, she must then take a shuttle bus to the terminal and go through security. The mean time for doing this is 15 minutes and the standard deviation is 2 minutes, and this time also is normally distributed. The drive time and airport time are independent of each other. What is the probability that Meg will miss her flight because her totally time for getting to the airport is more than 45 minutes?

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.

6

step-by-step explanation:

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
