The following data on sale price, size, and land-to-building ratio for 10 large industrial properties appeared in a paper. property sale price (millions of dollars) size (thousands of sq. ft.) land-to- building ratio 1 10.7 2165 1.9 2 2.7 751 3.5 3 30.5 2423 3.7 4 1.9 225 4.8 5 20.0 3916 1.7 6 8.0 2866 2.4 7 10.0 1697 3.1 8 6.6 1046 4.9 9 5.8 1109 7.5 10 4.6 405 17.3 (a) calculate the value of the correlation coefficient between sale price and size. (give the answer to three decimal places.)

step-by-step explanation:

de77737dd

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
