Wwhhaatt??? I have no idea what your question is.
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.
If you mean missing angle, it would be 129.
Answer:
44
Step-by-step explanation:
x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 294
Combine all like terms for x and integers
6x + 30 = 294
Minus 30 on both sides
6x = 264
Divide by 6
x = 44
Let's write the function that represents the problem:
ax = 210x + 240
We are going to evaluate the first five nights:
a0 = 210 * (0) + 240 = 240
a1 = 210 * (1) + 240 = 450
a2 = 210 * (2) + 240 = 660
a3 = 210 * (3) + 240 = 870
a4 = 210 * (3) + 240 = 1080
We then have the following terms:
240, 450, 660, 870, 1080
We observe that the common difference of the terms is:
210
Therefore, since they have the same common difference, we are facing an arithmetic sequence.
Answer:
A the situation represents an arithmetic sequence because of the successive and values have a common difference of 210
