Find the mean, median, and mode of the data set. Round to the nearest tenth.
test scores on a math exam:
83, 96, 67, 67, 86, 65, 82, 85, 97, 73, 85, 67, 99, 98, 65, 96, 70, 92, 74, 83,
72, 76
mean = 74.1, median = 82.5, mode = 67
mean = 80.8, median = 82, moda 67
mean = 80.8, median = 82.5, mode = 67
mean = 74.1, median = 82.5, mode = 82

The answer is: mean = 80.8, median = 82.5, mode = 67

Step-by-step explanation:

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
