Answer:
The measure of the he angle A is 360°
Answer:
Yes.
Step-by-step explanation:
This relation is a function because each input has one and only one output, i.e. 2 yields 1, 4 yields 2, 6 yields 3, 8 yields 4 and 10 has an output of 3. Therefore, it is a function.
Answer:
1
Step-by-step explanation:
3(x + 3) = 12
Multiply 3 by both numbers in the parentheses.
3x + 9 = 12
Subtract 9 from both sides of the equation.
3x = 3
Divide 3 from both sides of the equation.
x = 1
Answer:
28
Step-by-step explanation:
Answer: Third option is correct.
Step-by-step explanation:
Since we have given by
Event A: the red die shows 1
Event B : the numbers add to 4
Event C: at least one of the numbers is 3
Event D : the numbers do not add to 9.
D' means the number add to 9.
We need to write the following statement in symbolic form:
Either the numbers add to 9 or the red die shows a 1.
So, it becomes,

Number of elements in D'∪A = 1.
Hence, Third option is correct.
