Answer: 24 tests
Step-by-step explanation:
Ms. Carey graded 1/3 of the tests and still had 16 tests to go.
This means that the 16 tests represent the remaining proportion of the total number of tests:
= 1 - 1/3
= 2/3
2/3 of the total is equal to 16 tests. Assuming the total is x, the expression would be:
2/3x = 16
x = 16 ÷ 2/3
x = 16 * 3/2
x = 24 tests
Answer:
a) The number of visits between the patrons who buys the season passes shows higher frequency than those who did not buy season passes, in general. However, the minimum value of 1 visit is present for both cases.
b) The mean visits of the patrons are just PARAMETERS. If you want to test your hypothesis using hypothesis testing, the statistics are the z or t scores comparing the parameters (means).
c) The proportion who would have paid less are those with 2 or fewer visits because they would only just paid $82 instead of $100.
Number of patrons with 2 or fewer visits: 16
Total number of patrons who bought season passes: 30
Proportion who would've paid less = 16/30 = 0.5333

I just did it
Answer:
12 p - 8 p, 4p ( 3 - 2)
Step-by-step explanation:
p = equal the number of ounces of pasta salad in one container
then 12 × p = 12 p in 12 containers
the students finished the pasta salad in 8 containers which equals = 8 p
the number of ounces of pasta left = 12 p - 8 p
b) using the distributive property for example a ( b + c) = ( a×b) + (a ×c)
12 p - 8 p = 4p ( 3 - 2)

The answer is
67%.
The percentage error is 23%
Explanation:
The estimated total cost of the groceries = $50
The actual cost of the groceries = $65
To find the error value, we need to subtract the value of actual cost and total cost of the groceries.
Thus,
error value = actual cost - total cost
error value 
Hence, error value = $15
The formula to determine the percent error is given by
Substituting the values in the formula, we get,
Rounding off the value, we have, 23%
Thus, the percentage error is 23%
