Două unghiuri sunt adiacente atunci când au o față comună și un nod comun ( punctul colț ), și nu se suprapun.

(The question was asked in Romanian)

The answer is B. When you put all of the times people were arrested because of car stereo theft, Pilfer has the highest probability (12/29) compared to the other suspects.

Basically, you would, like CPhill said, add the values. 324+569+280+300+146+63+92+451 is 2225, and dividing that by the number of values (8) would get a final answer of the mean being 278.125, also translated as 278 1/8.

The answer is 469,135,782. Of you need help on mathematical equations, just refer to the site's calculator, easily accessed by clicking "home" or the site's logo.

You'd have to find the LCD again. Both denominators have the lowest multiple of 12 (4*4 is 12 and 4*3 is 12). Multiply the numerators by the number the denominators were multiplied by (1*3 and 1*4). The final equation would be 3/12*4/12=7/12. 7/12 of the flowers were either yellow or white.

First, you would need to make the denominators equal by finding the LCD (least common denominator).  Since 10 is the lowest multiple that the denominators have in common, that would be the new denominator. 5*2 is 10 and 10*1 is 10. Since you multiplied the 5 by 2, you would need to the same for the numerator, 1. 1*2 is 2, and the new fraction would be 2/10. 2/10 plus 3/10 is 5/10, simplified to 1/2. That means that the groundskeeper watered half of the plants.

First, you would have to make the mixed number, 15 3/4, to an improper fraction, 63/4. You would multiply the whole number by the denominator, and add the product to the numerator, in this case 15*4+3 being 63. Then you would multiply by 5. 5 is the same as 5/1, and to multiply fractions, you have to multiply the numerators together to find the new numerator, and vice versa with the denominators. 63*5 is 315, and 4*1 is 4, therefore making the answer 315/4. Finally, you simplify to 78 3/4.

-8/8 plus 8 would be 7 since -8 divided by 8 (division is the same as fractions) is -1, and -1+8 is 7.
