<h3>
Answer: Sample B as it has the smaller sample (choice #4)</h3>
===========================================================
Explanation:
Recall that the margin of error (MOE) is defined as
MOE = z*s/sqrt(n)
The sample size n is located in the denominator, meaning that as n gets bigger, the MOE gets smaller. The same happens in reverse: as n gets smaller, the MOE gets bigger. 
Put another way, a small sample size means we have more error because small samples mean they are less representative of the population at large. The bigger a sample is, the better estimate we will have of the parameter. 
We are told that "sample A had a larger sample size" indicating that sample A has a more narrow confidence interval. 
Therefore, sample B would have a wider confidence interval. 
This is true regardless of what the confidence level is set at.
 
        
        
        
This question was answered but no solution was given. 
We already solve for the B or area of the triangular base which was 5.25cm².
There are 2 triangular faces in the prism so 5.25cm² x 2 = 10.50cm²
There are 3 rectangular face in the prism, we need to get the area of each.
area of a rectangle = length x width
rectangle 1: 5 cm x 4 cm = 20 cm²
same dimension with rectangle 2. so, area is 20 cm² also
rectangle 3: 5 cm x 2.8 cm = 14 cm²
let us all add up the area of each surface.
2 triangle = 10.50 cm²
3 rectangles = 20 cm² + 20 cm² + 14 cm² = 54 cm²
10.50 cm² + 54 cm² = 64.50 cm²

Look below
Step-by-step explanation:
So I will use an example to try and show you how to do this.
If we have  , we know that we don't have like denominators. We can change this by finding one. All we need to do is multiply our denominators. So in our example, that would be
, we know that we don't have like denominators. We can change this by finding one. All we need to do is multiply our denominators. So in our example, that would be  . Our new denominator would be 6. So now we would have
. Our new denominator would be 6. So now we would have  which isn't the same as our old equation. That is because we haven't multiplied our top numbers yet. To do this, we need to multiply the top number by the opposite denominator like so,
 which isn't the same as our old equation. That is because we haven't multiplied our top numbers yet. To do this, we need to multiply the top number by the opposite denominator like so,  .
.
So our first fraction was 

We then multiplied the whole fraction by the opposite denominator
