x^2-16 factors to (x-4)(x+4)
You use the difference of squares rule here which is
a^2 - b^2 = (a-b)(a+b)
Answer:
$4918
Step-by-step explanation:
first income must be divided according to tax bracket
2% tax on first 3000 income= 2% of $3000=$60
3% tax on income after first 3000 but upto 5000= 5000-3000= $2000
=3% of 2000= $60
5% tax on income after second 5000 but upto 12000= 17000-5000
=12000 5% of $12000= $600
Lastly, 5.75% income over 17000=
90000-17000= $73000 so, 5.75 % of 73000= $4197.5
tax= $60+60+600+4197.5
= $4917.5
= $4918
Answer:
The probability that 8 mice are required is 0.2428.
Step-by-step explanation:
Given : A scientist inoculates mice, one at a time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.
To find : What is the probability that 8 mice are required? The probability that that 8 mice are required is nothing ?
Solution :
Applying binomial distribution,
Where, p is the probability of success
q is the probability of failure q=1-p,
n is total number of trials n=8
r=3
Substitute the values,
Therefore, the probability that 8 mice are required is 0.2428.
