40/9
Step-by-step explanation:
We first let 4.4 (4 being repeated) be x.
Since x is recurring in 1 decimal places, we multiply it by 10.
10x = 44.4
Next, we subtract them.
10x − x = 44.4 − 4.4
9x = 40
Lastly, we divide both sides by 9 to get x as a fraction.
x = 40/9

Answer:
Lower Quartile: 62
Upper Quartile: 81
Interquartile Range: 19
Step-by-step explanation:
To find the lower quartile, you want to find the median from the minimum to the median.
49, 55, 62, 64, 67
The median of this is 62. Therefore, 62 is the lower quartile.
To find the upper quartile, you want to find the median from the median to the maximum.
76, 79, 81, 82, 83
The median of this is 81. Therefore, 81 is the upper quartile.
To find the interquartile range, you subtract the upper and lower quartile.
81-62=19
The difference is 19. Therefore, the interquartile range is 19.
