Answer:
c. X= {0,1,3}
Step-by-step explanation:
We have these possible outcomes:
None assigned to their favorite cities.
One assigned to their favorite city(The other two are assigned to the other's favorite city).
All are assigned to their favorite city.
Why is two not possible?
If two peooke are assigned to their favorite city, the third person necessary has to be assigned to their favorite city, as it will be the only option remaining.
So the correct answer is given by option c.
Answer:
738π cm^3
1458π cm^3
Step-by-step explanation:
The volume of a cylinder is V = πr^2 h, where r=radius and h=height.
a) V = πr^2 h
= π6^2 20.5 = 36*20.5π = 738π cm^3
b) V = πr^2 h
For this one, remember that diameter is half of radius. d = 18, r = 9.
V = π9^2 18 = 81*18π = 1458π cm^3
18 wi 18 18 18 18 18 18 18
Answer:
The correct answer options are,
A: 0
B: There is one real root with a multiplicity of 2.
Step-by-step explanation:
Discriminant of a quadratic equation ax² + bx + c = 0 is given by,
b² - 4ac
It is given a quadratic equation 9x² + 24x + 16 = 0
<u>To find the discriminant </u>
Here a = 9, b = 24 and c = 16
Discriminant = b² - 4ac
= 24² - (4 * 9 * 16)
= 576 - 576
= 0
The correct options are
A: 0
B: There is one real root with a multiplicity of 2.
If you only have a piece of wood 7/8 feet long and you cut off a 1/4 feet piece, you are left with 5/8 foot board. all you have to do is to subtract 7/8 - 1/4.
7/8 - 1/4 = 7/8 - 2/8 = 5/8
