Answer:
D: 6/36
Step-by-step explanation:
As we are given the sample space, the events that sum to 6 are:
{(1,5), (2,4), (3,3),(4,2),(5,1)}
Let n(S) be the number of items in sample spae
n(S) = 36
Let E be the event the sum is 6
Then,
n(E) = 6
So,
P(Sum of two cubes is 6) = n(E) / n(S)
= 6/36
So, the correct answer is:
D: 6/36 ..
the right answer is an=5(3)^(n-1)/2

Answer: The missing value, y = 24
Step-by-step explanation:
The triangles are similar, so the sides are proportional.
The length of side BD is 10. The segment AD is also 10. Add them to get the length of side AB.
DE is 12
12:10 = y:20 . 20/10 = 2 2×12 = 24
Answer:
x = 11
Step-by-step explanation:
Properties of a square,
1). Diagonal of a square bisect the opposite angles.
2). All interior angles of a square measure 90°.
From these properties,
m∠PQR = 90°
Since, diagonal QS bisects angle PQR,
m∠PQS = m∠RQS = 45°
(6x - 21)° = 45°
6x = 45 + 21
6x = 66
x = 11
