It should be 34/5*. If you create an improper fraction out of the original one, then creating the reciprocal will be easier.

Answer:
   angles (W, X, Y) = (77°, 62°, 41°)
Step-by-step explanation:
<u>Given</u>:
   ΔWZY
   ∠W = 2(∠Y) -5°
   ∠X = ∠Y +21°
<u>Find</u>:
   ∠X, ∠Y, ∠W
<u>Solution</u>:
Using angle measures in degrees, we have ...
   ∠X + ∠Y + ∠Z = 180
   (∠Y +21) +∠Y + (2(∠Y) -5) = 180
   4(∠Y) +16 = 180 . . . . . simplify
   ∠Y +4 = 45 . . . . . . . . . divide by 4
   ∠Y = 41 . . . . . . . . . . . . subtract 4
   ∠W = 2(41) -5 = 77
   ∠X = 41 +21 = 62
The angle measures of angles (W, X, Y) are (77°, 62°, 41°), respectively.
 
        
             
        
        
        
Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of  , and a confidence level of
, and a confidence level of  , we have the following confidence interval of proportions.
, we have the following confidence interval of proportions.

In which
z is the z-score that has a p-value of  .
.
The margin of error is of:

In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that 
95% confidence level
So  , z is the value of Z that has a p-value of
, z is the value of Z that has a p-value of  , so
, so  .
. 
Margin of error:



The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
  
        
             
        
        
        
Answer:
she spent $1782 
Step-by-step explanation:
first we have to find out her total money then minus 990
to get that 990 /5 then multipliedby 6 is 1188
1188 over 3 then times by 7 is 2772
2772 is the total amount of money she had. minus what she had left which is 990 she has spent 1782 dollars
