Answer:

d) r = -65.

Step-by-step explanation:

The absolute value of r represents the relationship strength and the sign represents the relationship direction

Also if the relationship is nearest to 1 then it would be termed as positive correlated and if the relationship is nearest to -1 then it would be termed as negative correlated

Therefore based on the given options, the last option is correct

Option D: $x \geq 3$ is the solution

Explanation:

The given expression is $3 x-1 \geq 8$

We need to determine the solution of the expression.

<u>Solution:</u>

The solution of the expression can be determined by solving the expression for the variable x.

Thus, we have,

$3 x-1 \geq 8$

Adding both sides of the expression by 1, we get,

$3x\geq 9$

Dividing both sides of the expression by 3, we get,

$x \geq 3$

Thus, the solution of the expression is $x \geq 3$

Hence, Option D is the correct answer.

The variables x and y are related proportionally. When x = 4, y = 14. Find y when x = 40.

vichka [17]

Answer:

See Below

Step-by-step explanation:

Take the the given information and compare to the question being asked

$\frac{y}{x}$ . So insert the x & y's of both equations (ima do y over x to make it easier)

$\frac{14}{4} =\frac{y}{40}$

divide 14/4

3.5 = $\frac{y}{40}$

then multiply both sides by 40 to isolate y

140 = y

Check by reinserting 140 and divide it by 40
