Sry about the scribbles I was trying but I need help ASAP so try to answer it as fast as possible
QveST [7]

Answer:

The answer for A is 1500 and B is 150

Step-by-step explanation:

All you need to do is first make 25% into 25 over 100 or 25/100 then you divide which will give you 0.25 next you're gonna have to divide 375 by 0.25 which is 1,500. Then for B it do it again 60% to 60/100 next turn it into a decimal which is 0.60 or 0.6 then multiply 375 by 0.6 which is 225 then subtract 375 by 225 then you got the final answer:150. I hope I helped you

Set X consists of 100 numbers. The average (arithmetic mean) of set X is 10, and the standard deviation is 4.6. Which of the fol
kompoz [17]

Answer:

E. 10 and 10

Step-by-step explanation:

Standard Deviation is the square root of sum of square of the distance of observation from the mean.

Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }

where, \bar{x} is mean of the distribution.

Here, since standard deviation is the ratio of the distance from the mean and sample size. So for decreasing the standard deviation we should keep numerator constant and increasing the denominator.

This can be only possible in option (E).

Hence, only Option (E) is correct.
