the area of a rectangular decks is 680 square feet. the decks width is 17 feet. what is its perimeter ?

1 answer:

4 0

The perimeter is 114 square feet. To solve this, first you divide 680 by 17, which equals 40. So the length is 40. The formula for perimeter is 2L+2W. This means you take the length and multiply it by 2, and do the same for the width, then add them together. So the equation would be:
2(40)+2(17)=Perimeter
80+34=Perimeter
The final answer is 114 square feet.

Answer:

The correct option is;

The situation shows correlation without causation

Step-by-step explanation:

The given data are;

Weight y ${}$ Miles Per Gallon

42 ${}$ 18

36 ${}$ 12

30 ${}$ 6

. ${}$ x

24 ${}$ 0

The first difference of the data = 42 - 36 = 36 - 30 = 30 - 24 = 6

18 - 12 = 12 - 6 = 6 - 0 = 6

The first difference of the data is constant and equal to 6

Therefore, the graph is a straight line graph with y-intercept = 24 and slope given by the rate of change of the weight to the miles per gallon of fuel consumption as follows;

The rate of change of the weight to the miles per gallon of fuel consumption is given as follows;

(42 - 24)/(18 - 0) = 1

Therefore, the points of the data fit into the straight line and the data of the situation shows correlation

In order to show causation, and to rule out other possible causes for the rise in MPG, a separate experiment will be required whereby the cause for the rise in MPG can be determined.
