Telephone calls reach a secretary independently and at random ,internal ones at a mean rate of 2 in any five minute period and external ones at a mean rate of 1 in any five minute period . Calculate the probability that there is more than 2 calls in any period of 2 minutes

a and c

step-by-step explanation:

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).

the weight of the object inside the box!

the answer is 3/2 and for decimal: 1.5

hope i
