You want to build a wheelchair ramp leading up to your house. Your front door is 2 feet higher than the driveway and you would l
Alenkasestr [34]

Answer: (a) The angle the ramp forms with the driveway, s° = 4.004° (3 d.p)

(b) The driveway has to be, s = 28.57 ft

(c) The ramp will be 28.64 ft long

Step-by-step explanation:

First key thing to know is that the %grade of a ramp = rise/ramp run

%grade of a ramp = 7% = 0.07

(Kindly find attached a diagram to assist with understanding).

Also note that, <em>the ramp run is not the same as the ramp length</em>

(a) the angle, θ, is the angle of slope between the driveway and the ramp,

tan θ = 0.07,

θ = tan⁻¹ 0.07 = 4.004° (3 d.p)

(b) the length of the driveway (s) is the same as the length of the ramp run, so, %grade of a ramp = rise/ramp run

0.07 = 2/s

s = 2/0.07 = 28.57 ft (2 d.p)

(c) the length of the ramp can be found by using Pythagoras' theorem,

L = ramp length =\sqrt{rise^{2} + ramprun^{2} }

L = \sqrt{2^{2} +28.571^{2} }

L = \sqrt{820.3041}

L = 28.64 ft (2 d.p)

Assume that the time it takes the housekeeping crew of a local hotel to clean a room varies uniformly between 28 and 45 minutes.
siniylev [52]

Answer:

The probability that the next room will require less than 32 minutes to clean

0.222222 = 22.22%

The probability that the next room will require more than 30 minutes to clean.

0.833333 = 83.33%

The mean

36.5

Standard deviation of the distribution

26.92

Step-by-step explanation:

Total Probable Outcomes = 18

Event 1

Possible outcomes less than 32 = 32-28 = 4

Probability less than 32 = 4/18 = 2/9 = 0.222222

Event 2

Possible outcomes less than 32 = 45-30 = 15

Probability less than 32 = 15/18 = 5/6 = 0.833333

Mean

Mean = (28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45)/18 = 36.5

Standard deviation of the distribution
