1. First, put the range in order and then divide the set into quarters. In this case, quartiles are between numbers.83, 85, 89, l 91, 95, 104, l 112, 118, 118, l 125, 134, 138Q₁ = (89 + 91)/2 = 90Q₂ = (104 + 112)/2 =108Q₃ = (118 + 125)/2 = 121.5Interquartile range (IQR) = Q₃ - Q₁ = 121.5 - 90 IQR = 31.52. To find the standard deviation follow the simple steps.Formula in finding the standard deviation: (see attached file) Step 1. Work out the simple average of the numbers (mean) 212 + 249 + 212 + 248 + 239 + 212 + 216 + 234 + 248 9 = 2070 9mean (μ) = 230 Step 2. Subtract the mean on each number and square the result.212 - 230 = (-18)² = 324249 - 230 = ( 19)² = 361212 - 230 = (-18)² = 324248 - 230 = (18)² = 324239 - 230 = (9)² = 81212 - 230 = (-18)² =324216 - 230 = (-14)² =196234 - 230 = (4)² =16248 - 230 = (18)² =324
Step 3. Add all the squared results and get the mean. 2274 9 Variance = 252.6666667 Step 4. Get the square root of the variance. √252.6666667 = 15.89549202

$w\geq 14$

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

$2l+2w\geq 40$

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

$2\times 6+2w\geq 40$

now, we can solve for w

$12+2w\geq 40$

subtract both sides by 12

$12+2w-12\geq 40-12$

$2w\geq 28$

divide both sides by 2

and we get

$w\geq 14$

so,

the smallest possible measurement of the width is 14 feet

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
