Equation of parabola is .
<u>Step-by-step explanation:</u>
The vertex form of the parabola is given as,
where (h,k) is the vertex of the parabola.
If the parabola must be symmetric about x = -10 then the axis of symmetry must be x = -10.
To execute this, h should be -10, and it was plugged in the vertex form of the parabola, a and k may be any real number.
So the equation can be written as,

The 99% confidence interval for the population mean is 6± 2.443
<h3>Confidence interval</h3>
The formula for calculating the confidence interval is expressed as:
CI = x± z(s/√n)
GIven the following parameters
x = 6
s = 3
n = 10
z score at 99% = 2.576
Substitute into the formula to have:
CI = 6± 2.576(3/√10)
CI = 6± 2.443
Hence the 99% confidence interval for the population mean is 6± 2.443

Answer is D. Answers letter A,B,C are all linear.
you could ride 6 rides + the admission and it would equal $33. so the all day pass is cheaper than 6 or more rides :)
Answer:
2.5 mph
Step-by-step explanation:
Peter walks 2.5 miles per hour
If he walks 15 miles in 6 hours then divide 15 by 6
15 divided by 6 is 2.5 so every hour peter walks 2.5 miles or 2 1/2
