The step in this problem is do 1/4 + 1/3= ?
and see what you get
Answer:
105 if the triangle is 180
Step-by-step explanation:
The probability is 3/5. Since there are 5 out of 10 sections labeled with an even number, the denominator of the desired probability is 5. Since t<span>hree sections are both colored red and labeled with an even number, the numerator is 3. The probability is 3/5. We can also use conditional probability: P(A|B)=P(AUB)/P(B). Let A=section colored red, B=section labeled with even number. P(AUB)=3/10, while P(B) is 1/2, so P(A|B)=3/5.

For this case we must resolve the following inequality:
Subtracting 8 from both sides of the inequality:
Equal signs are added and the same sign is placed.
Thus, the solution is given by all values of "y" greater than or equal to -20.
Answer:
"y" belongs to the set [-20,∞)
