Answer:
B (-1 , -4)
Step-by-step explanation:
A (3 , 4)
M (1 , 0)
M is the midpoint of segment AB means :
Then
Then
Then
So probility is (disired outcomes) divided by (total possible outcomes) so
1st one is white roses
8 white roses so 8 is disired
total=5+3+8=16
8/16=1/2
then without replacing them
red=5
total possible=16-1 since 1 picked
5/15=1/3
then multiply the probatilities
1/2 times 1/3=1/6
it is a 1 in 6 probability
Answer:2x-5y=17;6x-5y=-9
Step-by-step explanation:
Solve equation [2] for the variable x
[2] 6x = 5y - 9
[2] x = 5y/6 - 3/2
// Plug this in for variable x in equation [1]
[1] 2•(5y/6-3/2) - 5y = 17
[1] - 10y/3 = 20
[1] - 10y = 60
// Solve equation [1] for the variable y
[1] 10y = - 60
[1] y = - 6
// By now we know this much :
x = 5y/6-3/2
y = -6
// Use the y value to solve for x
x = (5/6)(-6)-3/2 = -13/2
Let U be the universal set, where U=(1,2,3,4,5,6,7,8,9)let sets A and B. be subsets of U, whereA=(2,3,8,9) and B=(1,2,3,5)
Black_prince [1.1K]
(A U B) = {1, 2, 3, 5, 8, 9}
(A U B)^c = {4, 6, 7}
A^c = {1, 4, 5, 6, 7 }
B^c = {4, 6, 7, 8, 9}
A^c ∩ B^c = {4, 6, 7}
8 + 3(4 + 5)
8 + 3(9)
8 + 27 = 35
I got 75582.
Explanation:
First, group the 40 identical candies into 20 pairs. It doesn't matter how since the candies are identical. This grouping will ensure that any assigment will contain at least two candies.
Then think of the 20 groups a 20 beads on a string. We are looking to place 11 separators between them to obtain 12 segments, each with a varying number of beads between them. How many ways are there to place 11 separators to 19 potential spaces between beads? The asnwer is
