How can you tell the difference between a strong linear association and a weak linear association? 1. The data points will be clustered more tightly around the trend line if there is a weak linear association and less tightly if there is a strong one.

2. The data points will be clustered more tightly around the trend line if there is a strong or weak linear association.

3. The data points will be clustered less tightly around the trend line if there is a strong or weak linear association.

4. The data points will be clustered more tightly around the trend line if there is a strong linear association and less tightly if there is a weak one.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

step-by-step explanation:

i took the test: )

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
