Answer: A, read the information on the device's packaging
Explanation:
The info in the packaging has to be accurate because it goes through tests and they cannot make up info on there. This means any info about the materials used is accurate.
Answer:
-8 and 735
Explanation:
Since the sea is a body of water (fluid) it takes the same properties as a fluid does which means filling an area and finding a leveled point. This is why we use the sea as a starting elevation point for Earth's land and it is given a numerical value of 0. Since it starts at 0 any land above Sea Level is in the positives while land below Sea Level is in the negatives. Therefore Since New Orleans is 8 feet below sea level its numerical value elevation is -8. The highest point in Chicago is 735 feet above sea level which makes its numerical value 735
Answer:
Its nCr = n!/(r!.(n-r)! =n!/!!.(n-1)! = n
Explanation:
Here. the arrangement of outcome does not matters, and hence it is a combination. You should know that when arrangement matters then we have to calculate the permutation and its formula is n!/(n-r)!. However, here it is the combination, and hence its nCr or n!/r!. (n-r)!. And here r is 1 as we can have all heads or all tails. And n is n. Hence,
Its nCr = n!/(r!.(n-r)!
=n!/!!.(n-1)!
= n
