The following data was collected from 10 visitors to disneyland. a researcher stood at the entrance gate and interviewed the first 10 families that agreed to participate. each family was asked, “how many times have you been to disneyland? ” the data values were: 1, 1, 2, 2, 2, 2, 3, 3, 4, 7. the average number of visits was calculated and reported.

calculate the standard deviation of the data values.

The standard deviation is

Step-by-step explanation:

The given data are

Thus,

The mean for the data is given by

The standard deviation is given by

Substituting the values in the formula and simplifying the equation,we get,

Thus, the standard deviation for the data is

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the answer is (-4,-4)

hope this ! : d
