Answer:
The 99% confidence interval for the mean amount of money spent on lunch per week for all college students is between $41.40 and $44.60.
Step-by-step explanation:
A confidence interval has two bounds, a lower bounds and an upper bound.
These bounds depend on the sample mean and the margin of error.
The lower bound is the sample mean subtracted by the margin of error.
The upper bound is the margin of error added to the sample mean.
In this problem, we have that:
The sample mean is $43.
The margin of error is $1.60 for a 99% confidence interval.
Lower bound: 43 - 1.60 = $41.40
Upper bound: 43 + 1.60 = $44.60
The 99% confidence interval for the mean amount of money spent on lunch per week for all college students is between $41.40 and $44.60.

The terminal point is (0, 1) if the radius of circle is 1 and the value of an angle ø is 360 degree option (C) is correct.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a unit circle with an angle ø = 360 degree.
The terminal point will be:
x = rcosø
y = rsinø
r = 1
ø = 360 degree
x = cos360 = 1
y = sin360 = 0
The terminal point (0, 1)
Thus, the terminal point is (0, 1) if the radius of circle is 1 and the value of an angle ø is 360 degree option (C) is correct.
