Answer:
Surface area of cone is
Step-by-step explanation:
Given:
radius of a cone (r) = 8 feet
slant height of cone (l) = 12 feet
We need to find the surface area of cone.
Total surface area of cone = Area of circle Area of curved surface
Now we know that,
Area of circle =
Area of curved surface =
Hence Total surface area of cone =
Surface area of cone is .
Answer:
From the frequency table, let's calculate the row total.
Row total for phone call = 19 + 9 = 28
Row total for no phone call = 8 +6 = 14
To calculate their respective row relative frequencies, let's use:
Row relative freq =
Now, the two-way frequency table will be computed as:
For phone call:
Desirable behavior = ≈0.69
Undesirable behaviour = ≈0.32
No phone call:
Desirable behaviour = ≈ 0.57
Undesirable behaviour = ≈ 0.43
The complete two-way table is attached.
