The two tangents are parallel to each other because the two lines perpendicular to the same line are parallel to each other.
Lk + JK = JL
The answer is Parallel to each other
        
             
        
        
        
Answer:
a) 
b) The should sample at least 293 small claims.
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:
 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
, so  , which means that the answer of question a is z = 1.645.
, which means that the answer of question a is z = 1.645.
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.
 is the standard deviation of the population and n is the size of the sample.
(b) If the group wants their estimate to have a maximum error of $12, how many small claims should they sample?
They should sample at least n small claims, in which n is found when
 . So
. So







The should sample at least 293 small claims.
 
        
             
        
        
        
Answer:
She need to walk 31/75 miles to school.
Step-by-step explanation:
It is given that,
Sofia has walk  miles to school. She has already walk
 miles to school. She has already walk  of a mile.
 of a mile.
We need to find how much farther does she need to walk.
Total distance =   
 
Let she has to walk x distance to school.

Hence, she need to walk 31/75 miles to school.
