Answer:
Concept: Statistical Modeling
- N= 8 trials
- P= 0.25 or 1/4 chance
- You have 8 * 1/4 = 2 correct
We will use the Reminder theorem.
The polynomial f ( x ) is divisible by x - a when f ( a ) = 0.
For the 1st one:
f ( - 2 ) = ( - 2 )³ + 7 · ( - 2 )² + 14 · ( - 2 ) + 8 =
= - 8 + 28 - 28 + 8 = 0
For the 2nd one:
f ( 5 ) = 3 · 5³ - 12 · 5² - 4 · 5 - 55 =
= 375 - 300 - 20 - 55 = 375 - 375 = 0
Answer;
1. ( x + 2 )
2. ( x - 5 )
Answer:
b = - 0.389
Step-by-step explanation:
38/99=b+17/22
to solve this expression we would make b the subject of the formulae
and evaluate the other parameters.
38/99=b+17/22
collect the like terms
38/99 - 17/22 = b
22( 38) - 99 (17)/ 2178 = b
836 - 1683/2178 = b
-847/2178 = b
b = - 0.389
Answer:

Step-by-step explanation:
Do something like this but end at -3 1/4
Which is one dash past -3 towards the -4 I think bc -3 3/4 + 1/2= -3 1/4
