Answer:
The student who weighted the rock 5 times has a 95% confidence interval of (25.2, 29.1) which is guaranteed to be more wider (less precise) than the other student who weighted the rock 20 times.
Step-by-step explanation:
What is Confidence Interval?
The confidence interval represents an interval that we can guarantee that the target variable will be within this interval for a given confidence level.
The confidence interval is given by

Where
is the mean weight
is the standard deviation
is the critical value from t-table and n is the sample size.
The term
is known as margin of error.
As the sample size is decreased the corresponding margin of error increases which results in wider confidence interval which means smaller precision.
The student who weighted the rock 5 times has a 95% confidence interval of (25.2, 29.1) which is guaranteed to be more wider (less precise) than the other student who weighted the rock 20 times.
We can say with 95% confidence that the true mean weight of the rock is within the interval of (25.2, 29.1).
Answer:
When you have to get these measurements completely then you apply some multiplication as follows: Calculate cubic feet for different units (formula) From feet: length (ft) × width (ft) × height (ft) = cubic feet From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet
Step-by-step explanation:
I don't know, sorry
When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number:

. in our rational number the denominator is 1, and the numerator is 3
Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation:

. In this case, the numerator is 4, and the denominator is

.
We can conclude that the equivalent rational expression of <span>4 over x - 3 is </span>
