Answer:
D, 64%
Step-by-step explanation:
To solve algebraic equations, you have to do the inverse or opposite, so because you are multiplying x by 50 on one side and x wants to be alone, you have to do the opposite which is divide by 50 to get x*1 or just x (because 50/50 equals 1) and what you do on one side of the = sign you do on the other, so 32/50 = 0.64. Then to make a percent you move the decimal to the right by 2 places and you get 64%

Answer:
A. 30.144
Step-by-step explanation:
This is a Chi-Squared test
Given:




- The significance level is 5%, so

To use the Chi-Square distribution table, you need to know two values:
- Degrees of freedom = (n - 1)
- Significance level
Degrees of Freedom = n - 1 = 20 - 1 = 19
The significance level is 5%, so 
This is a one-tailed test since
so Upper tail area = 0.05
Reading from the table (attached), the critical value is: 30.144
(This means that we reject
if the test statistic is greater than 30.144)
