Step-by-step explanation:
s+u
Add t: You will need to introduce brackets 
(s+u) + t
Add v: Introduce another v
((s/u) + t) + v
 
        
             
        
        
        
Answer:
It's 63.29
Step-by-step explanation:
Step 1: We make the assumption that 158 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=158.
Step 4: In the same vein, x%=100.
Step 5: This gives us a pair of simple equations:
100%=158(1).
x%=100(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 158/100
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 100/158
x= 63.29%
Therefore, 100 is 63.29% of 158.

The hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.
<h3>How to illustrate the information?</h3>
The following can be deduced from the information:
x1 = 275
x2 = 170
n1 = 500
n2 = 500
The sample proportion will be:
p1 = 275/500 = 0.55
p2 = 170/500 = 0.34
The pooled proportion will be:
= (275 + 170)/(500 + 500)
= 0.44
The test statistic is 6.681. It should be noted that the test statistics is a number that's calculated by a statistical test. It shows how the observed data are far from the null hypothesis. 
The p value in this scenario is extremely small. The p value is a measurement used to validate a hypothesis against the observed data. Therefore, we have to reject the null hypothesis.
 
In this case, the hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.
