Answer:

Associative property

Step-by-step explanation:

we have given,

(k+l) + m = (m + k) + l

We can check this for both Commutative and associative properties.

Commutative property:

a + b = b + a

Associative property

(a + b) + c = a + (b + c)

so,

(k +l) + m = (m + k)+ l is showing Associative property of addition.

Given:
______________________________________________
$18.99 per 340.23 grams ;

and given:

1 gram ≈ 0.03527 oz (ounces) ;
______________________________________________
Find the unit price per OUNCE (oz).

The average life of an electric scooter is 12 years with a standard deviation of 1.5 years. The manufacturer replaces for free a

Dmitrij [34]

The guarantee which should be given by the manufacturer in years is; 0.405years

<h3>Percentages and Averages</h3>

Since the average life of a scooter is 12 years with a standard deviation of 1.5 years.

Hence, the maximum life of any electric scooter is 13.5 years.

On this note, to offer a guarantee with the intention to replace only 3% of the scooters;

We must evaluate 3% of 13.5 years as follows;

Guarantee offer = 3% of 13.5 years

Guarantee offer = (3/100) × 13.5

Guarantee offer = 0.405 years
