Answer:
6.5 x 10^6 To answer this question, you need to divide the mass of the sun by the mass of mercury. So 2.13525 x 10^30 / 3.285 x 10^23 = ? To do the division, divide the mantissas in the normal fashion 2.13525 / 3.285 = 0.65 And subtract the exponents. 30 - 23 = 7 So you get 0.65 x 10^7 Unless the mantissa is zero, the mantissa must be greater than or equal to 0 and less than 10. So multiply the mantissa by 10 and then subtract 1 from the exponent, giving 6.5 x 10^6 So the sun is 6.5 x 10^6 times as massive as mercury.

Answer:
Step-by-step explanation:
Given that that (X) the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distribution with a mean of 15 seconds.
i.e. X is normal with mean = 15 and unknown std deviation 
Given that
i.e. P(
z=-1.475 (from normal table)
Hence 
Using this we find P(X>17) = 
The answer is choice A- 68
Answer:
t + 8° > 82°
Step-by-step explanation:
Given that :
Let t = temperature when Susanne checks at 11:00
If t rises by 8 more degrees, it will break the record high temperature for that day
Record high temperature for the day = 82 degree
Hence,
Temperature at 11:00 + 8° > record high temperature for the day
t + 8° > 82°
X+(x+2)+(x+4)=3639
3x+6=3639
3x=3633
X=1211
Numbers are: 1211, 1213, 1215
X+(x+2)+(x+4)=672
3x+6=672
3x=666
X=222
Numbers are: 222,224,226
