Answer:
D. on the x axis is the best answer
Solving the equation, it is found that all equations that have a single solution at x = 12 have the same solution as the equation given.
----------------------
- The equation given is as follows:
- To find equations with the same solution, we have to find the solution of this equation.
- Thus, equations that have a single solution x = 12 have the same solution as the equation given.

Answer:
The point estimate for the proportion is p = 0.4725
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
Point estimate
95% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
Answer:
a = 3/2 b = -1 c = 7/2
Step-by-step explanation:
y = 1/2(3x+7)
y = (3/2)x + 7/2
(3/2)x - y + 7/2 = 0
