Answer:

For every 1 inch on the drawing, it's 3 feet in real life.

Step-by-step explanation:

First, consider the length. The length is 6 inches on the drawing, while in actuality it is 18 feet. So every 6 inches represents 18 feet. Let's make a ratio; 6 : 18. To simplify it, divide both sides by 6; 6 : 18 = 1 : 3.

For every 1 inch on the drawing, it's 3 feet in real life.

7x +2y = 24<br> 8x+2y= 30<br> What is x and y

Liula [17]

Answer:

x = 6

y = -9

Step-by-step explanation:

we have:

7x +2y = 24 equation 1

8x+2y= 30 equation 2

using equation 2 we have:

8x = 30 -2y

x= $\frac{30-2y}{8}$ equation 3

using equation 3 in equation 1 we have:

7( $\frac{30-2y}{8}$ )+2y = 24

$\frac{210}{8} - \frac{14y}{8} +2y =24\\\\\frac{1}{4}y = -\frac{18}{8} \\\\y=-\frac{18}{8} * 4\\\\y=-9$

so we have:

x= $\frac{30-2(-9)}{8}$

x= $\frac{30+18}{8}$

x=6

The correlation coefficient of the data given in the table, using a calculator, is of 0.35

<h3>How to find the correlation coefficient of a data-set using a calculator?</h3>

To find the coefficient, we need to insert the points (x,y) in the calculator.

In this problem, we have that:

The values of x are: 90, 95, 80, 84, 75, 80.

The values of y are: 80, 90, 90, 95, 75, 85.

Using a calculator, the coefficient is of 0.35.
