Answer:15

Step-by-step explanation:

Given

8 Workers can a work in 30 days

i.e. 1 workers can do the same job in 8\times 30=240\ days

If additional workers is hired to do the same work in 16 days

suppose Now x no of workers do the job so, one worker will do the same job in x\times 16

No of days require to complete the job by one worker  remains the same (considering all are equally efficient)

240=x\times 16

x=15\ workers

So a total of 15 workers is required to do the same job in 16 days

Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.
krok68 [10]

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!!!

When the outliers are removed, how does the mean change? dot plot with 1 on 50, 1 on 76, 1 on 78, 2 on 79, 1 on 80, 1 on 81, 2 o
sveticcg [70]
We can plot this data on MS Excel and determine the distribution of these data reflected on the graph. Among these numbers, 50 is the outlier since it is very far from the other numbers ranging from 76 to 83. We can perform interquartile range to determine or verify the outliers in the data set. In this respect, we can see that there is not much distribution seen. The average of all data sets is equal to 96.25. When the outlier (50) is removed, we expect the mean to become higher since a low number was ommitted including high numbers only. Outliers are obtained from special causations such as human errors.

What is the span of the roof? A. 4 ft B. 12 ft C. 18 ft D. 24 ft
RoseWind [281]

Answer:

  D.  24 ft

Step-by-step explanation:

The slope of 1/3 means the rise is 1/3 the run for each half of the span. The rise is shown as 4 ft, so the half-span is 3·4 ft = 12 ft.

The span of the roof is 24 ft.

The last option is the answer. You can double check by substituting the -3 for the x values and the 17 for y values and the statements would be true.
