Answer:
Mean = 51.4.
Mode = 49.
Median = 52.
Range = 6.
Step-by-step explanation:
Mean = Sum of all observations / Number of observations.
Mean = (49+49+54+55+52+49+52)/7
Mean = 360/7
Mean = 51.4 (to the nearest tenth).
Mode = The most repeated values = 49 (repeated 3 times).
Range = Largest Value - Smallest Value = 55 - 49 = 6.
Median = The central value of the data.
First, arrange the data in the ascending order: 49, 49, 49, 52, 54, 55, 55.
It can be seen that the middle value is 52. Therefore, median = 52!!!

Answer:
Jo's Number is 20.
Step-by-step explanation:
4 - ( 9 x ? ) = 176.
9 x 20 = 180.
9 x 20 = 180, then subtract 180 by 4.
180 - 4 = 176.
Therefore, Jo's number is 20.
