40%

Step-by-step explanation:

EZ PROBABILITY BOIII YE xD

ok so the numbers 7, 8, 9, 10 are applicable to this solution. that means out of all the numbers the probability that you choose a number higher than 6 is 40%

how do i get that? the formula is: the amount of solutions/the total amount of solutions. that's 4/10

make that 40/100 and convert to percentange: 40%

9514 1404 393

Step-by-step explanation:

The ratio of perimeters is the ratio of corresponding sides.

  first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters

The ratio of areas is the square of the ratio of linear dimensions.

  first : second = 4² : 3² = 16 : 9 . . . ratio of areas
