4. the number of children born per week in a certain hospital has a mean of 50.5 and a standard deviation of 5.5. this
distribution takes only whole number values and therefore is not normal
a. consider the mean number of babies born per week at the hospital during a year (52 weeks). (think of this as a sample
of 52 observations.) what is the approximate distribution of the sample mean based on the central limit theorem?

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
