Find the mean, median, and mode of the data set. round to the nearest tenth. test scores on a math exam: 88, 89, 65, 62, 83, 63, 84, 63, 74, 64, 71, 82, 66, 88, 79, 60, 86, 63, 93, 99, 60, 85 (1 point

Organize from smallest to greatest:

60, 60, 62, 63, 63, 63, 64, 65, 66, 71, 74, 79, 82, 83, 84, 85, 86, 88, 88, 89, 93, 99

the median is the middle number since there are 22 numbers in this data set the median will be the sum of the TWO middle numbers divide by 2

the two middle numbers are 74 & 79:
(74+79)/2 = 153/2 = 76.5

Median is 76.5

The mode is the number that occurs the most often in a data set.
In this case, the mode is 63 which occurs 3 times.

Mode is 63

The mean is the sum of the numbers in the data set divided by the amount of numbers in the data set.

the sum of the numbers is 1667.
there are 22 numbers in the data set.

1667/22 ≈ 75.8

Mean is 75.8

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
