A) √50 = 2√25 . Her mistake was that she confused the radicand (25) & the outside factor to the radicand that is 2. The write answer is 5√2 & not the opposite
b) Find 2 numbers where their square nears the lower & the upper end of 50.
For instance 7² = 49 & 8² =64 are the nearest lower & upper numbers that encompass 50
Hence we can write the following inequality:
49<50<64 & √49<√50√64 ==> 7<√50<8
So the √50 is nearer to 7² rather than 8².
Then let's try 7.1² =50.41 Which is an acceptable approximation
Answer:
The answer is 6.93 inches of snow.
Step-by-step explanation:
Snow fall on Sunday: 0.93. Twice as much on Monday: 0.93x2=1.86
Add it all up: 0.93+4.14+1.86=6.93
3 standard deviations away would be adding the standard deviation 3 times, <span>5 + 8.3 + 8.3 + 8.3</span>
