Which statement is true about correlation: the correlation between two variables depends on their covariance and on the variance of each of the variables. the pearson correlation coefficient is based on the ranks of the data points, like the wilcoxon test. a correlation of -1 means that there is no linear relationship between the two variables. the spearman correlation coefficient requires x and y to be normally distributed.

step-by-step explanation:

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
