Answer:
n = - m or n = -0.5 - 1.5m
Step-by-step explanation:
21m + 14n = -7 (subtract 21m from each side)
14n = -7 - 21m (divide everything by 14)
n = - m
n = - m or n = -0.5 - 1.5m
The difference in salary is 36000-28000=8000
The difference in annual increase is 3000-2000=1000
Therefore it takes 8000/1000= 8 years to catch up.
At the end of eight years,
Salary with the first company = 28000+8*3000=52000
Salary with the second company = 36000+8*2000=52000
Answer:
And the determination coeffcient is just the correlation coeffcient square and we got:
And rounded to the nearest tenth thousand would be 0.1521
Step-by-step explanation:
The correlation coefficient is a measure of variability and is given by this formula:
For this case we have
And the determination coeffcient is just the correlation coeffcient square and we got:
And rounded to the nearest tenth thousand would be 0.1521
Answer:
z-score for 900 points = -4
Step-by-step explanation:
To find the z scores
z=(x-mean)/standard deviation
so
z=(900-1500)/150
z= -600/150
