The number of ships to arrive at a harbor on any given day is a random variable represented by x. The probability distribution of x is as follows. (Give your answers correct to two decimal places.)

col1 x 10 11 12 13 14
col2 P(x) 0.37 0.07 0.11 0.13 0.32
(a) Find the mean of the number of ships that arrive at a harbor on a given day
(b) Find the standard deviation, ?, of the number of ships that arrive at a harbor on a given day.

the answer is a beach is the best place to be

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
