Find the mode of the data set: 37, 42, 39, 44, 47, 38, 42, 45, 49, 35

mode = 42

Step-by-step explanation:

The mode is the value which occurs most often in the data set.

42 occurs twice, others only once, thus

mode = 42

x = 60

Step-by-step explanation:

If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary and their sum is 180°.

2x + 5 + x - 5 = 180

3x = 180

3x : 3 = 180 : 3

x = 60
