Correlation coefficient is the numerical representation of how one variable predicts the change of the other. In this case, if the AP tests scores and the SAT scores have 0.93 correlation coefficient, this means that the two results move in the same direction. When AP test results go up, then we can say that SAT scores will go up too, same also if one goes down, so does the other.
Answer:
x = 111 degrees
Step-by-step explanation:
the angle next to 164 degrees :
any line = 180 degrees, so 180 - 164 = 16 degrees
now you have two out of three angles in the triangle. All three angles of every triangle must add together to equal 180, so
180 = 53 + 16 + x
or
x= 180 - 53 - 16
x=111 degrees

Answer:
x +2y = 36
2x+3y =64
Step-by-step explanation:
x = price of a T-shirt
y = price of a puck
Adam buys a T-shirt and two souvenir pucks for $36.00
x +2y = 36
Luke spends $64.00 on two T-shirts and three pucks
64 = 2x+3y
Our system of equations is
x +2y = 36
2x+3y =64
