Answer:
Segment BF = 16
Step-by-step explanation:
The given theorem states that a line parallel to one side of a triangle divides the other two sides proportionately
The given theorem is the Triangle Proportionality Theorem
According to the theorem, given that segment DE is parallel to segment BC, we have;
Therefore;
Which gives;
Similarly, given that EF is parallel to AB, we get;
Therefore;
Which gives;
Therefore, the statement that can be proved using the given theorem is segment BF = 16.
Answer: 1.509
Step-by-step explanation:
The formula of Margin of Error for (n<30):-
Given : Sample size : n= 22
Level of confidence = 0.99
Significance level :
Using the t-distribution table ,
Critical value :
Standard deviation:
Then, we have
Hence, the margin of error for a 99% confidence interval for the population mean =1.509
Answer:
15.7
Step-by-step explanation:
d = 2r
d = 8 thus r = 4
area (kelly) = 4 x4 x = 16
area (paige) = 3 x 3 x = 9
difference = 16 - 9
= 5
= 15.7
