Value of x using quadratic formula (x = -4) and (x = -5)
Step-by-step explanation:
Given:
Equation
x² + 9x + 20 = 0
Find:
Value of x using quadratic formula
Computation:
Quadratic formula = [-b±√b²-4ac] / 2a
Given equation;
x² + 9x + 20 = 0
a = 1 , b = 9 , c = 20
By putting value
[-9±√9²-4(1)(20)] / 2(1)
[-9±√81-80] / 2
[-9±√1] / 2
(-9 + 1) / 2 , (-9 - 1) / 2

The prices in the sample are roughly symmetric with no distinct outliers. Based on this sample, which of the following is closest to a 90\%90%90, percent confidence interval for the mean price of gasoline that day in her state?
Answer:

Based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).
What is random sample?Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.
When the sample size is less than 30, the formula which is used is,
[tex]\overline x\pm t.\dfrac{s}{\sqrt n}[/tex]
Here, n is the sample size, [tex]\overline x[/tex] is the sample mean, s is the standard deviation.
Economist, takes an SRS of 12 gas stations. The sample size for the given problem is 12,
[tex]n=12[/tex]
Thus, degree of freedom,
[tex]df=12-1\\df=11[/tex]
In the t table, for df 11, the value of t is 1.796.
An economist studying fuel costs wants to estimate the mean price of gasoline in her state on a certain day.
On that day, she takes an SRS of 12 gas stations and finds the sample mean price (in dollars per gallon) is,
[tex]\bar x=2.29[/tex]
With a standard deviation of
[tex]s_x=0.20[/tex]
Put the values in the above formula,
[tex]2.29\pm 1.796.\dfrac{0.20}{\sqrt 12}\\2.29\pm 0.1037\\2.29+0.1037=2.3937\\2.29- 0.1037=2.1863[/tex]
Thus, based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).
