Answer : definitely sampling error
In every case, use the secant rule for chords: the product of the lengths on either side of the pont of intersection is the same.
Left-to-right, top-to-bottom:
1. 8x = 6*10
.. x = 60/8 = 7.5 (M)
2. 2x = 4*6
.. x = 24/2 = 12 (Y)
3. 16x = 4*14
.. x = 56/16 = 3.5 (T)
4. x² = 4*9
.. x = √36 = 6 (W)
5. 4x = 2*8 . . . . . . the diameter is 10. It is divided into parts that are 2 and 8.
.. x = 16/4 = 4 (A)
6. 6x = 7*13 . . . . .. same as previous. The overall length of 20 is divided into parts that are 7 and 13.
.. x = 91/6 ≈ 15.2 (D)
_____
The letter sequence makes no sense to me. I expect it is supposed to spell something intelligible.
Answer:
False
Step-by-step explanation:
False because you plug in 2 for d and makes the equation 81 + 2x2 > 90 then it`s just simple math 2x2 is 4 making it 81 + 4 > 90 and the answer is 85 > 90 which is false
This question we do not have to over think. We can already answer this with out the help of the diagram. The diagram helps us see that this problem involves the number line. Positive and negative numbers are involved in the number line.
Here how we can think about it: From the middle to the left the length is 39 and to the right it is 19. The length is then 58.
Answer:
25
Step-by-step explanation:
25-5=20, 5/4*20=25
