Answer:
Step-by-step explanation:
Given:
Given root is
Now we need to find the quadratic equation for given roots.
Solution:
The given roots are -14 and 0.
So, the sum of the roots.
Product of the given roots
Therefore, the required quadratic equation is.
-------------------(1)
Now we substitute 
and 
in equation 1.
Therefore, the quadratic equation for the given root is.
Answer: b; y intercept between 8 and 4
Step-by-step explanation:
1. a; 2/3
2. b; 3, all real numbers except x=2
3. a; $.75
4. c; intercepting at (-3,-3)
5. b; 5
6. a; starts at 3
7. b; 1975
8. b; y intercept between 8 and 4
The sample mean of the random sample is 50
The margin of error (E) is the amount of error allowed in the random sample.
The confidence interval (CI) is given by:
CI = μ ± E = (μ - E, μ + E)
Given a confidence interval of (38.02, 61.98), hence:
μ - E = 38.02 (1)
μ + E = 61.98 (2)
Hence solving equations 1 and 2 simultaneously gives:
μ = 50, E = 11.98
Hence the sample mean of the random sample is 50
