PLEASE HELP! The formula F = 95C + 32, where C stands for temperature in degrees Celsius, is used to convert Celsius to Fahrenhe
1 answer:
The temperature is 86°F when the temperature is 30°C.
Step-by-step explanation:
Formula for Celsius to Fahrenheit;
F =
Where C stands for temperature in degrees Celsius.
Given,
Temperature in Celsius = 30 degrees
Temperature in Fahrenheit =
Temperature in Fahrenheit =
Temperature in Fahrenheit =

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.
