A16 1/2 kilometer stretch of road needs repairs. workers can repair 2 1/4 kilometer of road per week. how many weeks will take to repair this stretch of road?

Step-by-step explanation:

we know that

To find out how many weeks it will take to repair this stretch of road, divide the total length of the road by the workers' rate

so

Convert mixed number to an improper fraction

substitute

Convert to mixed number

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the answer will be
