He answer is around 385 I believe??? Im not positive if thats what u wanted or not.
Answer:
B is the best answer
The question is illustrated with the attached figure.

Determine XY
To solve for XY, we make use of the tan function, which states that:
tan\theta = \frac{Opposite}{Hypotenuse}tanθ=
Hypotenuse
Opposite
In this case:
tan\ 60= \frac{YZ}{XY}tan 60=
XY
YZ
Substitute 4 for YZ
tan\ 60= \frac{4}{XY}tan 60=
XY
4
Make XY the subject
XY= \frac{4}{tan\ 60}XY=
tan 60
4
tan\ 60 =\sqrt 3tan 60=
3
So, the expression becomes:
XY = \frac{4}{\sqrt 3}XY=

Rationalize:
XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}XY=

XY = \frac{4\sqrt 3}{3}XY=

Answer:
the best point estimate to use as an estimate of the true mean tip per delivery would be $1.88
the distribution that will be used to obtain the critical value is that you should try to find the population standard deviation and then find out what 90% of that is
