Answer:

X=-1.1 repeated

Step-by-step explanation:

9x - 1= -11

Answer:

- 1 1/9

Step-by-step explanation:

9x - 1 = -11

Add 1 to both sides to eliminate -1 on the left side

9x - 1 + 1 = -11 + 1

9x = -10

Divide both sides by 9 to isolate x

9x/9 = -10/9

x = - 1 1/9

Scott took out a 4-year car loan for $5,500. He paid back a total of $7,370. What interest rate did he pay for this loan?
elena-14-01-66 [18.8K]
Amount of car loan taken by Scott = $5500
Amount of loan paid back by Scott = $7370
Then
Amount of money paid as interest by Scott = (7370 - 5500) dollars
                                                                     = 1870 dollars
Then
Percentage of interest given for the car loan = (1870/5500) * 100
                                                                       = 1870/55
                                                                       = 34 percent
So Scott had to pay a total interest rate of 34% in the four years.I hope the procedure is simple enough for you to understand and solve future problems.

the gross earnings • group health insurance (assuming 15% of gross earnings) pension deduction (assuming 6.5% of gross earnings)
sveta [45]

Step-by-step explanation:

<u>Calculate the gross earnings:</u>

  • 40*7.75 = 310.00

<u>Health insurance deduction:</u>

  • 310.00*15/100 = 46.50

<u>Pension deduction:</u>

  • 310.00*6.5/100 = 20.15

<u>Total deductions:</u>

  • 55.00 + 15.50 + 21.25 + 46.50 + 20.15 = 158.40

<u>Net pay:</u>

  • 310.00 - 158.40 = 151.60

binomial(16 + 7, 16) 2^(-(16 + 7)) = ((16 + 7)!)/(16! 7! 2^(16 + 7)) = 245157/8388608 ≈ 0.02922 ≈ 1/34.22

(assuming children are independent and male and female are equally likely)

| probability

less than 16 boys | 0.9534

16 or less boys | 0.9827

more than 16 boys | 0.01734

16 or more boys | 0.04657

fraction of boys | 16/(16 + 7) ≈ 0.695652

fraction of girls | 7/(16 + 7) ≈ 0.304348

expected value | 11.5
