Answer:
0.6848
Step-by-step explanation:
Mean of \hat{p} = 0.453
Answer = 0.453
Standard deviation of \hat{p} :
= \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = \sqrt{\frac{0.453(1-0.453)}{100}} = 0.0498
Answer = 0.0498
P(0.0453 - 0.05 < p < 0.0453 + 0.05)
On standardising,
= P(\frac{0.0453-0.05-0.0453}{0.0498} <Z<\frac{0.0453+0.05-0.0453}{0.0498})
= P(-1.0044 < Z < 1.0044) = 0.6848
Answer = 0.6848

for 2/3 just dvide by 6, 24/36 just multiply both terms by 2 and for 6/9 just divide by 2</span>
        
                    
             
        
        
        
Answer:  or
 or 
Step-by-step explanation:
 For this exercise you can convert the mixed number to an improper fraction:
 1. Multiply the whole number part by the denominator of the fraction.
 2. Add the product obtained and the numerator of the fraction (This will be the new numerator).
 3. The denominator does not change.
 Then:
 
 You know that he had 30 minutes in time-out, he counted spots on the ceiling for  minutes and the rest of the time he made faces at his stuffed tiger.
 minutes and the rest of the time he made faces at his stuffed tiger. 
 Then, in order to calculate the time Calvin spent making faces at his stuffed tiger, you need to subract 30 minutes and  minutes:
