Step-by-step explanation:
The distance between park station 1 and the point where the flare was set off is 73.9 km.
<h3>What is distance?</h3>
Distance is the length between two points expressed in meters or kilometers.
To calculate the distance between park station 1 and the point where the flare was set off can be calculated using Sine Rule
Formula:
- a/sinA = b/sinB....................... Equation 1
Where:
- a = Distance between park station 1 and the point where the flare was set off.
Make a the subject of the equation
- a = bsinA/sinB............ Equation 2
From the diagram,
Given:
- A = 59°
- B = (180-59-75) = 46°
- b = 6.2 km
Substitute these values into equation 2
Hence, the distance between park station 1 and the point where the flare was set off is 73.9 km.

Step-by-step explanation:
Answer:
Students who have z-scores above z = 2.00 are the ones who scored above 90.4.
Step-by-step explanation:
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The mean test score in her upcoming class is 49, and the standard deviation is 20.7.
This means that 
Identify the test score corresponding to a z-score of above z=2.00.
As X increases, so does the z-score. So those scores are higher than X when Z = 2.
Students who have z-scores above z = 2.00 are the ones who scored above 90.4.
