Answer:
It would be the second distribution in the fist picture, and the first distribution in the second picture
Step-by-step explanation:
The median is the middle number of a set of numbers, for example, the median in 3, 5, 9, 10, 11, 15, 20 would be 10, since it is the middle number. For the two distributions, that is the best measure of center
Answer:
The number 10/7 is a rational number, which means it can be expressed as a fraction. Also, if we divide it would give a decimal infinite periodical number, which means it has a pattern on its decimal numbers.
On the other hand, the square root of 2 is irrational number, that means it can't be expressed as a fraction, because its decimal numbers don't have any pattern at all.
So, Mai's brother can see these type of numbers as crazy (irrational numbers) and sane (rational numbers).
At last, another important characteristic to shows that they aren't equal is that they don't have the exactly decimal numbers.
Answer:
245 flash drives
Step-by-step explanation:
We can assume that the proportion of broken flash drives in the 200 drive sample is the same as the proportion of broken flash drives in the weekly output. Therefore, if we let 
be the number of broken flash drives produced that week, we can write the following equation:
Solving for , we get:
(Multiply both sides of the equation by 
to isolate )
flash drives (Multiply)
Hope this helps!
Answer:
2x+8 and 2(4+x)
Step-by-step explanation:
Its 2x+8 because all you have to do is distribute the 2. So 2 times x is 2x and 2 times 4 is 8. You can just rearrange it for 2(4+x)
