It’s still 6 because adding a constant does not change the standard deviation.
irina1246 [14]2 years ago

Answer:  I believe the standard deviation will remain the same, 6, choice A.

Step-by-step explanation:  Standard deviation is calkculated based on the difference of each point from the mean.  If 10 were added to each score, the mean would also increase by 10.  That would mean that the difference between the mean and each score would be exactly the same, leading to an identical standard deviation.  Sounds crazy, but that's what numbers do for a living.

Step-by-step explanation:

In a stack of 24, the 2 mediums are odd and even cards in this question. This means that 1/2 the cards are even and 1/2 are odd. To get a even card once is a 1/2 chance, then to get it again is 1/2 x 1/2 chance or 1/4 chance. This is what I think.

Answer:

The direct consequences of poverty are well-known — limited access to food, water, health care or education are a few examples. However, the consequences of poor living conditions on the community are seldom discussed; indeed, if members of a community suffer from poor living conditions, then the entire community suffers.
