Answer:
The correct option is (b)
Only II applies.
Step-by-step explanation:
Given
dy/dx = (x - 2)/(y - 2)
We want to check which of the given options is true.
I) produces a slope field with horizontal tangents at y = 2
This is not true
II) produces a slope field with vertical tangents at y = 2
This is true because putting y - 2 = 0, we have dy/dx ---> infinity.
Which is a slope field with vertical tangents at y - 2 = 0 or y = 2.
III) produces a slope field with columns of parallel segments
This is not true.
450/25= 18
where 450 is $4.50 and 25 is one quarter. there will be 18 quarters.
560-450=110
110/10=11
where 110 is $1.10 and 10 is one dime. there will be 11 dimes.
11+18= 29
where 11 is total number of dimes and 18 is total number of quarters. and 29 is total number of coins
Answer:
A normal distribution or z-test is used to construct a confidence interval.
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= $3120
Sample size, n = 40
Population standard deviation, σ = $677
The distribution of earnings of college is a normal distribution.
Conditions:
- Since we are given the population standard deviation and the the sample size is also greater than 30.
Conclusion:
Thus, we use a normal distribution or z-test to construct a confidence interval.
Because the Median could be anywhere within the interquartile range the upper quartile could be between 10 and 15
