It would be D because you have to do the cube root on both sides. What I do is ignore the decimal and add it in later once the math is complete like on this question you can tell by process of elimination that 8 squared is 64 but you’re look for the cube root so that eliminates a and c and now just make sure the decimal is in the right place
        
             
        
        
        
Answer:
80
Step-by-step explanation 
Write down the equation: (15 / 100) * x = 12
Solve for x: x = 12 / (15 / 100)
x = (12 * 100) / 15
or, x = 80
    Hope this helps!
 
        
             
        
        
        
Answer:
0.04
Step-by-step explanation:
2 / 50 is the same as 1 / 25.
1 / 25 = 0.04
 
        
                    
             
        
        
        
Answer:
The minimum sample size that should be taken is 62.
Step-by-step explanation:
We have that to find our  level, that is the subtraction of 1 by the confidence interval divided by 2. So:
 level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of  .
.
So it is z with a pvalue of  , so
, so 
Now, find the margin of error M as such

In which  is the standard deviation of the population and n is the size of the sample.
 is the standard deviation of the population and n is the size of the sample.
If we want to be 90% confident that the sample mean is within 1 word per minute of the true population mean, what is the minimum sample size that should be taken
This is n when  . So
. So





The minimum sample size that should be taken is 62.
 
        
             
        
        
        
The inequality negative 3 and one-half greater-than negative 4.5 or -3.5 > -4.5 is true.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
 
We have inequalities given:

or
1.5 > 2.5  (false)
1/2 > 0.5
0.5 > 0.5 (false)
-2.5 > -1.5 (false)

-3.5 > -4.5  (true)
Thus, the inequality negative 3 and one-half greater-than negative 4.5 or -3.5 > -4.5 is true.
