Answer: 170% da da
Step-by-step explanation:
Answer:
(1,4) ( 4,1) (2,3) (3,2)
Step-by-step explanation:
Multiples of 5 = 5 and 10
Ways to roll a 5 = (1,4) ( 4,1) (2,3) (3,2)
Ways to roll a 10 = (5,5) (4,6) (6,4)
We have 7 possible outcomes for a multiple of 5...and there are 36 possible outcomes in total
So P (multiple of 5) = 7 / 36
Answer:

Step-by-step explanation:
Given
Represent the number with x.
So:

or

We want to solve for x
Subtract both sides by 2


Solve for x


No other number aside 0, satisfy the property.
Answer:
option (2)
Step-by-step explanation:
Using the cofunction identity
cosx = sin(90 - x) , then
cosb = sin(90 - b) = 0.75
