A researcher is 95% confident that the interval from 5.8 minutes to 9.3 minutes captures u = the true mean amount of time it takes to pump a full tank of gas in a certain type of SUV,
Is it plausible that the true mean number of minutes to fully fill a tank of gas for this type of SUV may be 9?
No, this is not a plausible value for the population mean, because 9 is within the 95% confidence interval.
No, this is not a plausible value for the population mean, because 9 is below the upper bound of the 95%
confidence interval
Yes, this is a plausible value for the population mean, because 9 is within the 95% confidence interval.
Yes, this is a plausible value for the population mean, because 9 is not within the 95% confidence interval.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
