Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not well-ventilated, they may contain radon gas. In one study, the radon levels in a sample of 1212 tombs in a particular region were measured in becquerels per cubic meter left parenthesis Bq divided by m cubed right parenthesisBq/m3. For this data, assume that x overbarxequals=3 comma 6853,685 Bq divided by m cubedBq/m3 and sequals=1 comma 1041,104 Bq divided by m cubedBq/m3. Use this information to estimate, with 9595% confidence, the true mean level of radon exposure in tombs in the region. Interpret the resulting interval.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

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
