Answer:
Step-by-step explanation:
<u>Question 7</u>
Angle formed by 2 chords is half of the sum of the intercepted arcs
- x = 1/2(72° + 58°) = 1/2(130°) = 65°
<u>Question 8</u>
Angle formed by 2 secants is half of the difference of the intercepted arcs
- x = 1/2(360° - (130° + 98° + 41°) - 41°) = 1/2(50°) = 25°
<h2><u>
Definitions/How to Find It</u></h2>
Mean - The average of all of the numbers. Add up all of the numbers then divide it by the total number of numbers.
Median - The middle number of them all. Put the numbers in order from least to greatest and find the one in the middle.
Mode - The number that appears the most.
Range - The difference between the highest and lowest numbers Subtract the lowest number from the highest number.
<h2><u>
Answers</u></h2>
Mean = 56.6
Median = 53
Mode = 41, 43, 63
Range = 56
Answer:
Step-by-step explanation:
2x - y = 8
<u> x + y = - 2 </u>
3x = 6
3x /3 = 6/3 Dividing bot sides by 3 to find x.
x = 2
Plug in the value of x to find y.
2 ( 2) - y = 8
4 - y = 8
-y = 8 - 4
- y = 4
y = -4
The solution: ( 2, -4)
