Answer:
the perfect squares between 120 and 300 are the squares of numbers from 11 to 17. Clearly, these are 7 in number.
Step-by-step explanation:
Answer:
The answer to your question is 2x² + 3x + Remainder (17x - 7)/ ( 2x⁴ + 3x³ - 4x² + 5x - 7)
Step-by-step explanation:
2x² + 3x
x² - 4 2x⁴ + 3x³ - 4x² + 5x - 7
-2x⁴ + 4x²
0 + 3x³ + 0 + 5x
- 3x³ +12x
0 +17x - 7
Quotient = 2x² + 3x
Remainder = 17x - 7
Solution = 2x² + 3x + (17x - 7)/ ( 2x⁴ + 3x³ - 4x² + 5x - 7)
Process
1.- Divide the first term of the divident by the first term of the divisor and place the result above the first term of the divident.
2.- Multiply the result of the division (2x²) by the first term of the divisor and change the sign of the result.
3.- Multiply the result (2x²) by the second term of the divisor and place the result below the like term.
4.- Add the results.
5.- Continue with this process until the remainder be lower than the divisor.
Answer:
You keep them if you test 3 and all pass.
There are 18 good ones and 6 bad (making 24)
Chance of first passing is 18/24
If it passes, there are now one less good and one less total.
Chance of second passing is 17/23
If it passes, there are now one less good and one less total.
Chance of second passing is 16/22
Total is (16 x 17 x 18) / (22 x 23 x 24) = about 0.4 (0.403162055 is you really want to know).
So probability all are ok is 0.4
Thus probability you find at least one bad one is 0.6
Hope this helps you out!
13 + (15) = 28
Because you always add the numbers in the parenthesis so 12 + 3 = 15 and 13 + 15 = 28
the correct question in the attached figure<span>
we know that
</span>the probability
that a witness picks a particular person by chance-----> P=1/5
the probability
that all 7 witnesses would pick the same person-----> P=1/5^7=0.0000128
the answer is the option B 0.0000128
<span>There are a variety of problems in which the number of witnesses change, for example
</span><span>....find the probability that all
9 witnesses would pick the same person
</span>in this case, the probability would be-------> P=1/5^9=0.000000512<span>
