Alina has 3/2 hours to complete her homework. She plans to split apart rhentime equally between 3 assignments. Which expression
e-lub [12.9K]
C. 3/2 divided by 3

Alina has 3/2 hours to complete her homework. She should divide her 3/2 hours by the 3 assignments to determine how much time she will spend on each assignment. This turns out to be 1/2 hours, or 30 minutes, on each assignment. 3/2 hours is the same thing as 90 minutes, so this answer makes sense. We want the time to be divided by the number of assignments, not vice versa.

If f(x) = x 2 + 1 and g(x) = 3x + 1, find [f(2)-g(1)] 2. 1 2 9
arsen [322]
Put the argument value where the variable is, then evaluate.
For f(x), you want f(2).
  f(2) = 2² + 1 = 4+1 = 5

For g(x), you want g(1).
  g(1) = 3·1 +1 = 4

For [f(2) - g(1)] you want the difference of the above values.
  [f(2) - g(1)] = [5 - 4] = 1

sveta [45]

Answer:

The 99% confidence interval for the mean number of hours of part-time work per week for all college students is between 25.8 and 30.2.

Step-by-step explanation:

A confidence interval has the following format.

\mu_{x} \pm M

In which \mu_{x} is the mean of the sample and M is the margin of error.

In this problem, we have that:

\mu_{x} = 28, M = 2.2

\mu_{x} - M = 28 - 2.2 = 25.8

\mu_{x} + M = 28 + 2.2 = 30.2

The 99% confidence interval for the mean number of hours of part-time work per week for all college students is between 25.8 and 30.2.
