Correct option is A) [-13/4, 9/4] .
<u>Step-by-step explanation:</u>
Here we have following equation as |2 + 4x| = 11 or ,
. We need to solve for the value of x .Let's find out:
We know that Modulus Function is both positive & negative for particular values of x , i.e.
|2 + 4x| is positive :
⇒ 
⇒ 
⇒ 
⇒ 
|2 + 4x| is negative :
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , Correct option is A) [-13/4, 9/4] .
Answer:
exponents
Step-by-step explanation:
1st term: n = 1
apply the value 1 to n in the equation:
1(1-1) - 5
1(0) - 5
0 - 5
- 5
Second term n = 2
2(2 - 1) - 5
2 (1) - 5
2 - 5
-3
Since we know the 1st term is -5 in the sequence and the second is -3, we can assume the answer is D. -5, -3, etc
Minimum required sample size for a desired margin of error and confidence level when it is a proportion problem: n = (z2÷margin of error2)*p-hat*q-hat
The maximum value of p-hat*q-hat occurs where p-hat = .5 (found by taking the derivative of (p-hat)*(1-p-hat) and setting it equal to 0 to find the maximum. n = ( 2.5762( for 99% confidence interval)÷.0482 )*.5*.5 = 720.028 or 721
