1 radios: 24, 22, 20, 18, 16, 14, 12
2. hours independent, radios dependent
3. (0, 24); (2, 22); (4, 20); (6, 18); (8, 16); (10, 14); (12, 12)
4. 2 radios sold 2 hours
5. goes down by 2
6. n = -h + 24
7. the amount is decreasing every hpur
Each loop is of a different size, so we can't rotate the figure some angle x to have it line up with itself (0 < x < 360). Therefore, it doesn't have any rotational symmetry. That rules out choice A and choice C. Point symmetry is the same as saying "rotational symmetry of 180 degrees"
The figure doesn't have any line symmetry either. There is no line we can draw and reflect the figure over to have it match up with itself. That rules out choice B and points to choice D
Answer: D) It has no reflectional symmetry.
Answer:
attached below
Step-by-step explanation:
Attached below are the Venn diagrams
A : 48 < X < 52 cm
B : 9 < Y < 11 cm
a) A
b) A ∩ B
c) A' ∪ B
d) A ∪ B
e) for events to be mutually exclusive it means that both events can not occur simultaneously i.e. A ∩ B = 0
the process would not be successful hence the process would not produce parts with X = 50 cm and Y = 10 cm
