1/15
1/3 chance of getting elf, 1/5 chance of getting magic so the chance of getting both is 1/3x1/5=1/15
The answer i got is 44/3 but as a mixed number it’s 14 2/3
Answer: V = 
Step-by-step explanation: A solid formed by revolving the region about the x-axis can be considered to have a thin vertical strip with thickness Δx and height y = f(x). The strip creates a circular disk with volume:
V =
Δx
Using the <u>Disc</u> <u>Method</u>, it is possible to calculate all the volume of these strips, giving the volume of the revolved solid:
V = 
Then, for the region generated by y = - x + 4:
V = 
V = 
V = 
V = 
V = 
The volume of the revolved region is V =
OK dose solve for x we n33d to get x by its self so 42/7 is 6 x is 6
You could use a simple calculator it's only 10.
