maria spins the spinner shown here 50 times. the table summarizes her results

a. find the theoretical probability that the spinner lands on e or c.
b. find the theoretical probability that the spinner lands on b.
c. find the experimental probability that the spinner lands on d.
d. find the experimental probability that the spinner lands on a.

*** the spin wheel has: the chart has: outcome number of times
2-a's a 10
3-b's b 12
2-c's c 8
4-d's d 14
1-e e 6

Can someone me with my hwplz(only the circled ones)

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so,about which interval is it approximately symmetric?
