Answer
35 = 1,5,7,35
Step-by-step explanation:
If E is the midpoint, DE and EF are equivalent.
2x+4=3x-1
4=x-1
5=x
Plug the value of x in
2(5)+4
14
3(5)-1
14
14+14=28
Final answer: DE=14, EF=14, DF= 28
In geometry, the three undefined terms are: the point, the plane and the straight line.
Since all the given graphs represent lines,we will need to choose the straight line among them.
Straight line is a line that has no start and no end.
From the choices:
Figures a and c are rays
figure b is a line segment
figure d is a straight line
Therefore, the correct choice is: D
Answer: (0.3751,0.4821)
Step-by-step explanation:
Given : Level of significance : 
Then , significance level : 
Since , sample size :
, i.e. a large sample (n<30).
Then we use z-test.
Using excel (by going in formulas for more statistics and then statistics), Critical value : 
Also, the proportion of people said that they were fans of the visiting team :-

The confidence interval for population proportion is given by :-


Hence, a 95% confidence interval for the population proportion of attendees who were fans of the visiting team= (0.3751,0.4821)
