Answer:
These outcomes are disjoint.
Step-by-step explanation:
(a) Are the outcomes none, small, and big disjoint
If they are disjoint, the sum of the total number of each has to be equals to the number of emails.
We have:
3921 emails.
549 with no numbers.
2827 with only one or more small numbers
545 had at least one big number.
549 + 2827 + 545 = 3921
Since the sum is equals to the number of emails, these outcomes are disjoint.
Use Pythagorean theorem
A^2 + B^2 = C^2
12^2 + B^2 = 15^2
Solves for b
To find volume of a cylinder, you must find the area of the base and multiply it by the height of the object.
V=Bh where B=area of the base. Since the base is a circle, we must find area of the circle. A=pi(r^2)
A=3.14(6^2) Since it gave us the diameter, we take half for radius. Solve A=3.14(36)
A= 113.04 square cm
Now to find volume.
V=113.04•11
V=1243.44 cubic cm
Now find volume of the cone on top.
V=1/3Bh again with B= area of the base (pi)(r^2)
Since the two objects share a base, we can use the area of the cylinder as above.
V=1/3(113.04)9
We have to do a little simple math to determine the height of just the cone. Total height is 20-11 height of the cylinder. The difference is 9.
V=1/3(113.04)9 multiply
V=339.12 cubic cm
Now add the two volumes together to find total volume.
Total V=1243.44+339.12
V=1582.56 cubic cm
Answer:
9 tapes
Step-by-step explanation:
First, subtract the handling charge from his $78.
78 - 3.50 = 74.5
So, Brian has $74.50 to purchase tapes. Each tape costs $7.50, so let's find out how many he can purchase.
74.50 / 7.50 = 9.933 (approximately)
Since Brian can't buy 0.933 of a tape, he will only be able to buy 9 tapes.
