Answer:
The measure of angle YUV is 40°
Step-by-step explanation:
Consider the diagram of this question is attached below,
Where, Tangent line UV and secant XY intersect outside the circle at U,
Since,

We have,




Since, the measure of intercepted angle outside the circle is half of the difference of measure of intercepted arcs,




Answer:
1.85%
Step-by-step explanation:
→ Find the difference between the actual and predicted
5.5 - 5.4 = 0.1
→ Divide answer by 5.4
0.1 ÷ 5.4 = 0.01851851851
→ Multiply answer by 100
0.01851851851 × 100 = 1.85%
Answer:

Step-by-step explanation:
From the question we are told that:
Mean 
Flaws 
Distance 
Generally the equation for Poisson mean lambda over 1000 is mathematically given by

Therefore



I believe that the answer is 12.5%
Reason 100% of 80= 80,
So if 80=100%,
then that means 10=x%
Fore it means that,
%=12.5%
Radius squared times pie
and diameter squared times pie
