Answer:
D(h) = 55h - 2000
1670 m
Step-by-step explanation:
Given :
Starting elevation, D = - 2000 m (2000 m below sea level)
Rate, h = 55 m per hour.
The slope - intercept relation :
y = mx + c
m = slope = rate of change
c = intercept
In the scenario given :
-2000 = intercept
55 = rate of change
D(h) = 55h - 2000
After 6 hours :
D(6) = 55(6) - 2000
D(6) = - 1670 m
Answer: 84.13%
Step-by-step explanation:
Given : The scores in a a language test with normally distributed.
Mean : 
Standard deviation: 
Let x be the random variable that represents the scores of students.
Formula for z-score: 
For x= 60 , we have

The probability f test takers scored a 60 or above :-

Hence, the percentage of test takers scored a 60 or above = 84.13%
