Assuming the distribution is continuous, you have
If instead the distribution is discrete, the value will depend on how the interval of number between 1 and 29 are chosen - are they integers? evenly spaced rationals? etc
Answer:
if you are asking 20% of 80, then its 16
Step-by-step explanation:
0.2 x 80 = 16
Since the triangle is isosceles the measure of angle B is also 47.
since you have dropped a perpendicular bisector the measure of angle x is 90. and since the angles must add to 180 you get 47+47+a=180 and a= 86. since y is half this we have y is 43

Answer:
.
Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportions for this case are different so then there is enough evidence to conlcude that the real proportion change.
Step-by-step explanation:
Information provided
represent the number of people who answer abstainers in 1947
represent the number of people who answer abstainer recnetly
sample 1 selected
sample 2 selected
represent the proportion estimated of people who answer abstainers in 1947
represent the proportion estimated of people who answer abstainers recently
represent the pooled estimate of p
z would represent the statistic
represent the p value
significance level given
Hypothesis to test
We want to verify if the proportion of adult Americans who totally abstain from alcohol changed , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Where 
Replacing the info given we got:
Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportions for this case are different so then there is enough evidence to conlcude that the real proportion change.
Answer:
the other part would be 0
Explanation:
If the whole = 8 and one part takes 8 then there can not be another part.
