To form the <u>converse</u> of the <u>conditional statement</u>, interchange the <u>hypothesis</u> and the <u>conclusion</u>.
Given conditional statement: "if two angles are both obtuse, the two angles are equal".
Here,
- hypotesis is: two angles are both obtuse,
- conclusion is: two angles are equal.
Then the converse statement will be: "If two angles are equal, then two angles are both obtuse".
Yes the sides are equal to each other
Answer:
23.83
Step-by-step explanation:
5/11 = 18/y
5 y = 18 · 11
5 y = 198
y = 198 : 5
y = 39.6
Answer:
The sample size required is at least 171
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
What sample size is required?
A samle size of at least n is required, in which n is found when 
So
Rouding up
The sample size required is at least 171
