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 (Bq divided by m cubed )Bq/m3. For this data, assume that x overbarxequals=3 comma 4713,471 Bq divided by m cubedBq/m3 and sequals=1 comma 1601,160 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.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

the barter

find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .

step-by-step explanation:

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
