Answer:
Step-by-step explanation:
Using the product to sum formula
sinxcosy = [ sin(x + y) + sin(x - y) ] , then
2sinxcosy = sin(x + y) + sin(x - y)
Given
2sin75°cos15° ← with x = 75 and y = 15 , then
= sin(75 + 15) + sin(75 - 15)
= sin90° + sin60°
= 1 +
=
Answer:
C) ±8/5
Step-by-step explanation:
Both the numerator and the denominator are positive squares (8 is the square root of 64, and 5 is the square root of 25). Finding the square root of both the numerator and the denominator will yield the simplified fraction ±8/5.
Remember: the square roots of a positive square are always both positive and negative. The square root of is 2 (
) and -2 (
)

Answer:
The probability of getting two numbers whose sum is greater than 9 and less than 13 is
Step-by-step explanation:
Given : A single 6-sided die is rolled twice.
To find : The probability of getting two numbers whose sum is greater than 9 and less than 13 ?
Solution :
The set of 36 equally likely outcomes,
1 2 3 4 5 6
1 (1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)
2 (2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)
3 (3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)
4 (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)
5 (5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)
6 (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)
Getting two numbers whose sum is greater than 9 and less than 13
The favorable outcome is (4,6),(5,5),(5,6),(6, 4),(6, 5),(6, 6) = 6
The probability is given by,
Therefore, The probability of getting two numbers whose sum is greater than 9 and less than 13 is
