Answer:

-2.6

Step-by-step explanation:

10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6

Elodia [21]

Answer:

40/76 or 10/19 or 52.63% (they are all equivalent)

Step-by-step explanation:

there are 76 parking spaces in total

30 parking spaces have numbers that are less than 31 (1 - 30)

that means that there are 76 - 30 = 46 spaces that are numbered 31 or higher

so the probability that Jillian parks on a parking space with a number ≥ 31 is 40/76 or 10/19 or 52.63%
