Answer:
Step-by-step explanation:
<em>(a).</em> 2( 2 )³ + a ( 2 )² - b ( 2 ) + 12 + ( 18 ) = 0
16 + 4a - 2b + 30 = 0
4a - 2b = - 46
<em>2a - b = - 23</em> ....... <em>( 1 )</em>
2 ( - 4 )³ + a ( - 4 )² - b ( - 4 ) + 12 = 0
- 128 + 16a + 4b + 12 = 0
16a + 4b = 116
<em>4a + b = 29</em> ........ <em>( 2 )</em>
<em>( 1 )</em> + <em>( 2 )</em>
6a = 6 , <em>a = 1</em>
4(1) + b = 29 , <em>b = 25</em>
<em>(b).</em> 2x³ + x² + 25x + 12 = 0
= <em>- 4</em> ( given: f(x) is divisible by x + 4 )
= <em>0.5</em>
= <em>3</em>
The probability that the lock code will begin with the number 5 is; 1/9 while the probability that the code will not contain the number 0 is; (8/9)³.
<h3>What is the probability that the lock code will begin with the number 5?</h3>
It follows from the task content that the probability of different scenarios of the lock code.
The probability that the lock code will begin with the number 5 is; 1/9 following from the definition of probability as the ratio of the number of required outcome to the number of possible outcomes.
