Answer: :o I FINALLY MADE IT

(5, 2)

x = 5

y = 2

Step-by-step explanation:

First, I graphed both equations.  They meet at the points (5,2) and (2,5).  Because y < 5, the solution is (5, 2)

Answer:

x=5\\y=2

Step-by-step explanation:

x^2 +y^2 =29

x+y=7

Solve for x in the second equation.

x+y=7

x+y-y=7-y

x=7-y

Plug in the value for x in the first equation and solve for y.

(7-y)^2 +y^2 =29

y^2-14y+49+y^2 =29

2y^2-14y+20=0

2(y-2)(y-5)=0

2(y-2)=0\\y-2=0\\y=2

y-5=0\\y=5

y

y=2

y\neq 5

Plug y as 2 in the second equation and solve for x.

x+y=7

x=7-y

x=7-2

x=5

Describe the relationship between two variables when the correlation coefficient r is one of the following. (a) near –1 strong
zepelin [54]

Answer:

a) strong negative linear correlation.

b) Weak or no linear correlation.

c) strong positive linear correlation.

Step-by-step explanation:

The correlation coefficient r measures the strength and direction (positive or negative) of two variables. The correlation coefficient r is always between -1 and 1. When the coefficient r is negative then the direction of the correlation is downhill (negative) and when it's positive then it's an uphill correlation (positive). Similarly, as the coefficient is closer to -1 or 1 the correlation is stronger, with zero being a non linear relationship.

Now back to the question:

a) Near -1: as we said before, this means an strong negative (-1) linear correlation.

b) Near 0: weak or no linear correlation (we cannot say if its positive or negative because we don't know it it's near zero from the right (positive numbers) or the left (negative numbers)

c) Near 1: strong positive (close to +1) linear correlation
