You have a normal distribution of hours per week that music students practice. The mean of the values is 8 and the standard deviation of the values is 4.

According to the normal distribution model that corresponds to this population, what percentage of the students practice between 6 to 10 hours per week?

Use the graph of the standard normal distribution given below to find the percentage.

34%
30%
19%
38%

There is no image of the graph but if its the one i think i did yesterday the answer would be 30%

Step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:
