A wheel has 10 equally sized slices numbered from 1 to 10. Some are grey and some are white.
The slice numbered 3 is grey.
The slices numbered 1, 2, 4, 5, 6, 7, 8, 9, and 10 are white.

The wheel is spun and stops on a slice at random.
Let X be the event that the wheel stops on a white slice, and let P(X) be the
probability of X
Let not X be the event that the wheel stops on a slice that is not white, and let
P(not X) be the probability of not X.
(a) For each event in the table, check the outcome(s) that are contained in the event. Then, in the last column, entert

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
