The age of the van owned = 12 years

The age of the truck owned = 29 years

Step-by-step explanation:

Here, the given question is INCOMPLETE.

Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?

Let us assume the number of years Laura has owned the van = S years

So, according to the question:

The number of years she has owned truck = S + 17 years

Now, Sum of the age of ( Truck + Van) = 41 years

⇒ (S + 17 years) + (S years) = 41 years

or, 2 S + 17 = 41

or, 2 S = 4 1 -1 7 = 24

or, S = 24/2 = 12 years

or, S = 12 years

Hence the age of the van owned = 12 years

The age of the truck owned = S + 17 = 12 + 17 = 29 years

I got the answer as letter C, can someone check me to make sure that is correct? Thank you in advance.

Answer:

The x's cancel so definitely is choice C: 1/9

Step-by-step explanation:

We have root( 1/(x^2) ) * root ((x^2) / 81)

simplifying this we get as follows:

root( 1/(x^2) ) * root ((x^2) / 81)

= $\sqrt{(1/x^2 )}$ * $\sqrt{(x^2)/81}$

= ( 1/x ) * (x/9)

the x's cancel

= 1/9

choice C 1/9

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.
