Answer: 9

Step-by-step explanation:

Based on the information given in the question, the expected number of people who pass will be calculated as:

= Probability of passing the driving test × Number of people tested

= 65% × 15

= 0.65 × 15

= 9.75

Therefore, expected number of people who pass is 9.

BRAINLIEST ASAP! PLEASE. HELP ME :) I need help with part 2 of the question.
tino4ka555 [31]

Part 2:

-4a + 2 + 11a = 5a + 3 + 2a

~Combine like terms

7a + 2 = 7a + 3

~Subtract 2 to both sides

7a = 7a - 1

~Subtract 7a to both sides

0 = 1

Therefore, there are no solutions.

Best of Luck!

shepuryov [24]
Hello there!

75 + 35 = 110

110 x 10% = 0.1

110 x 0.1 = 11 ( the 11 is your tax )

75 + 35 = 110

110 + 11 = 121

$121
