If the gardener want the length to be 14 feet longer than it is wide, then L=w+14.  We are given an area of 112.  The area formula for a rectangle is A=L*W.  Filling in accordingly, 112 = (w+14)(w).  Distributing we have 112=w^2+14w.  We are looking for the dimensions of the garden, so we have to solve for w.  To do that we have to factor. Set it equal to 0 to get the quadratic w^2+14w-112=0.  Plug that into the quadratic formula to get w values of 5.69 and -19.69.  The 2 things in math that will never EVER be negative are time and distance/length so we will not use the negative value.  Therefore, our width is 5.69.  Our length of w+14 is then 5.69+14 is 19.69.  There's our dimensions:  width is 5.69 and length is 19.69

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.
