Answer:
a) 2.5% b) 84% c) 95% d) D. The more unusual day is if the stock closed below $185 because it has the largest absolute z-score.
Step-by-step explanation:
For a) b) and c) we will use the empirical rule, so, we can observe the image shown below
a) 211.23 is exactly two standard deviation above the mean, so, the probability that on a randomly selected day in this period the stock price closed above 211.23 is 2.35% + 0.15% = 2.5%
b) 204.11 represents exactly one standard deviation above the mean, so, the probability of being below 204.11 is 50% + 34% = 84%
c) The probability of getting a value between 182.75 and 211.23 is 95%, this because 182.75 is exactly two standard deviations below the mean and 211.23 is exactly two standard deviations above the mean.
d) The z-score related to 208 is 
= (208-196.99)/7.12 = 1.5 and the z-score related to 185 is 
= (185-196.99)/7.12 = -1.7, therefore, the more unusual day is if the stock closed below $185 because it has the largest absolute z-score.
Your answer would be the last option, D.
This is because spinning the spinner does not affect which marble you pick, as these are mutually exclusive events. This means that if the spinner lands on red, you could choose a black or white marble, and if the spinner lands on green you could also choose a black or white marble.
The only sample space that represents this is D because it's the only one that includes both black and white options after spinning red and green.
I hope this helps!
Yes that is correctamundo..............
No slope
If you were to graph it the line would be straight across with no rise
Answer:
8 feet
Step-by-step explanation:
The diagram is attached below.
Note that the values are different but the diagram is similar. In this case,
Hypotenuse =17ft
Adjacent = 15²
Required
Opposite side
To get the feet of landscape edging would be required to outline the edge of the bed, we will use the Pythagoras theorem as shown;
Hyp² = Opp²+Adj²
Opp² = Hyp²-Adj²
l² = 17²-15²
l² = 289-225
l² = 64
l = √64
l = 8feet
Hence the feet of landscape edging would be required to outline the edge of the bed is 8 feet
