Aspinner has five sections, labeled a, b, c, d, and e. the spinner is spun 45 times, and the results are recorded in the table. what is the experimental probability of the spinner’s landing on c? round to the nearest percent, if necessary. outcome a b c d e number of trials 6 10 8 12 9 a. 8% b. 18% c. 20% d. 24%

A,B,C,D,E are 5 letters so you must divide 45 by 5. Equaling 9. so 9 over 45 in fraction form. But you need to simplify it so you divide the numerator and denominator by 3. Therefor creating 3 over 15 in fraction form. Then you divide both again by 3. Creating 1 over 5 of course in fraction form. Finally you divide 1 by 5 Equaling .2 or in another form .20. So you answer is .20

TADA!!! YOUR WELCOME I WORKED REALLY HARD TO DO THIS LMAOO

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

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.
