Suppose that two​ variables, x and​ y, are negatively associated. does this mean that​ above-average values of x will always be associated with​ below-average values of​ y? explain. choose the correct answer below. a. ​no, because association does not mean that every point fits the trend. the negative association only means that​ above-average values of x are generally associated with​ below-average values of y. b. ​no, because there will always be at least one point that does not fit the trend. c. ​no, because when two​ variables, x and​ y, are negatively​ associated, above-average values of x are associated with​ above-average values of y. d. ​yes, because if one or more​ above-average values of x are associated with​ above-average values of​ y, the variables cannot be negatively associated.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

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

3 ft is your answer
