Answer:

  • D.  15.3%

Step-by-step explanation:

<u>Total number of outcomes:</u>

  • 2¹⁵ =  32768

<u>Number of combinations of getting 6 heads:</u>

  • 15C6 = 15!/6!(15-6)! = 5005

<u>Required probability is:</u>

  • P(6 heads out of 15 flips) = 5005/32768 = 0.1527... ≈ 15.3%

Answer:

option D

Step-by-step explanation:

Total sample space

                               =  2^{15}

Number of ways 6 heads can emerge in 15 flips

                                                                          = 15C_6  

Probability:

               =\frac{15C_6}{2^{15}} = 0.1527

Probability to the nearest percent : 15.3%

Keisha just deposited a total of 900 into savings accounts at two different banks. the 550 she deposited at bank A will earn 2.2
mars1129 [50]

Answer:

F.

Step-by-step explanation:

Find how much interest she will earn from bank A:

100% = 550

1% = 550 ÷ 100 = 5.5

2.25% = 12.375

Find how much interest she will earn from bank B:

900 - 550 = 350

100% = 350

1% = 350 ÷ 100 = 3.5

3% = 3.5 x 3 = 10.5

Find out how much money she will earn from both banks of their interest:

10.5 + 12.375 = 22.875

Find out how much money she will earn from both banks of their interest in 2 years:

22.875 x 2 = 45.75

Find out how much she earns from both banks including interest:

900 + 45.75 = 945.75
