The following data gives the retail price (per square-foot) and durability score (assigned by an independent firm) for randomly selected types of laminate flooring available in a particular hardware store. Test the claim that there is a monotonic correlation between a laminate floor's retail price and durability score. Use the 0.05 significance level and Spearman's rank correlation test. What is the value of the TEST STATISTIC used in this hypothesis test

283 square feet

step-by-step explanation:

good luck

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
