The complete question in the attached figure
we know that
[<span>amount of fabric]=8*[area of lateral triangle side]
area of lateral triangle side=(1/2)*4*5----> 10 ft</span>²
so
[amount of fabric]=8*[10]----> 80 ft²
the answer is80 ft²

Question- 
6/15 divided by 1/7
Answer- 
Find the reciprocal of the divisor
Reciprocal of 1/7: 7/1Now, multiply it with the dividend
So, 6/15 ÷ 1/7 = 6/15 × 7/1= (6 × 7)/(15 × 1) = 42/15After reducing the fraction, the answer is 14/5In mixed form: 2 4/5
        
                    
             
        
        
        
Answer: <em>59.2</em>

<em>Take your equation</em>
<em>z2+8y</em>
<em>Now plug in the values given</em>
<em>(12)2+8(4.4)</em>
<em>24+35.2</em>
<em>59.2</em>
 
        
             
        
        
        
Answer:
A. The larger the sample size the better.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean  and standard deviation
 and standard deviation  , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean  and standard deviation
 and standard deviation  .
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean  and standard deviation
 and standard deviation 
In this question:
We have to look at the standard error, which is:

This means that an increase in the sample size reduces the standard error, and thus, the larger the sample size the better, and the correct answer is given by option a.
