The probability that none of the four have been vaccinated is
(1-0.63)^4 = 0.01874161
The probability that at least one has been vaccinated is the complement of this,
≈0.9813
It should be the second one
Answer: d. 102
Why
If 6 is 78 then 5 is 102 and since 1,3,5,and 7 are equal 3 is 102. [180-78=120(180 is the straight line)]
Time for first plane = 625 / 250
= 2.5 hours
after 1.25 hours
boeing 747 takes 1.25 hours (2.5 - 1.25) to arrive at the same location at the same time
so, speed = distance / time
= 625 / 1.25
= 500
the average speed of the boeing 747 is 500 mph
1.) The answer is 825.75 (multiply the given tax rates to the gross pay)
2,785 x 13% federal taxes = 362.05
2,785 x 9% state tax = 250.65
2,785 x 7.65% FICA = <u>213.05
</u> 825.75
<u>
</u>2.) The answer is 288.60 (multiply the interest rate to the balance, no need to add a late payment fee since they paid on 6/1, not after)
2,748.56 x 10.5% = 288.60
3.) The answer is 182.13 (multiply the APR to the original purchase price, no need to add the sales tax)
<u /> 1,500 x 11.75% = 182.13
4.) The answer is 371.92 (deduct the reward to the interest)
Interest : 2,975.34 x 13.5% = 401.67
Reward : 2,975.34 x 1% = <u> 29.75</u>
371.92
5.) The answer is 1,339.13 (deduct the interest to the monthly payment)
Monthly payment : 2,236.00
Monthly interest : <u> 896.87</u> [(231,450 x 4.65%) / 12 months]
<u /> 1,339.13
Hope this helps! :)
