Which equation best represents the axis of symmetry?
1 answer:
Answer: Hewo Hooman!!! The standard form of equation of a horizontal parabola is x = a y 2 + b y + c where a , b , and c are all real numbers and a ≠ 0 and the equation of the axis of symmetry is y = − b 2 a . Compare the equation with x = a y 2 + b y + c to find the values of a , b , and c .

Answer:
And the confidence interval would be between 42.001 and 47.399
Step-by-step explanation:
Information given
represent the sample mean for the sample
population mean
s=6.96 represent the sample standard deviation
n=28 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence interval is 0.95 or 95%, the significance is and
,the critical value for this case would be
And replacing we got:
And the confidence interval would be between 42.001 and 47.399
Slope: 8/9
y-intercept: (0,-8)
