It is thought that prehistoric indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. it is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. let x be the elevation (in thousands of feet) for an archaeological site in the southwestern united states. let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. suppose that the following data were obtained for a collection of archaeological sites in new mexico: what percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? answer a. 95.7% b. 0.7% c. 8.4% d. 91.6% e. 4.3%

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
