Answer:
- Washington had 196 hits
- Sanchez had 194 hits
Step-by-step explanation:
Let s represent the number of hits Sanchez had. Then Washington had (s+2) hits, and their hit total was ...
s +(s+2) = 390
2s = 388 . . . . . . subtract 2
s = 194 . . . . . . . . divide by 2
Sanchez had 194 hits; Washington had 196.

Answer: Correct choice is A.
Answer:
Mean = 151.375
Median = 152.5
Mode = None
Range = 115
Step-by-step explanation:
To find the mean:
Add the numbers and then divide by how many numbers there are:
150+125+162+178+98+213+155+130 = 1211
1211/8 = 151.375
To find the median:
Arrange in order from least to greatest:
98, 125, 130, 150, 155, 162, 178, 213
Median is the middle number. Because there is no middle number, average 150 and 155:
150+155 = 152.5
To find the mode:
Count how many times each number appears in the set. In this case, every number appears once, so there is no mode.
To find the range:
Subtract the highest number from the lowest number to find the difference:
213-98 = 115
