<h3>Inequalities</h3>Inequalities is a mathematic expression that do not present equalitiy between both sides. It is represented by symbols: <, ≤, > and ≥.
For solving this exercise, firstly, you should solve the inequalities identified by letters: H, W, M, Y and C. After that, you should relate yours anwers with the options given for the exercise.
- Inequality H
Therefore, you should connect H with x<1.
- Inequality W
Therefore, you should connect W with x>-2.
- Inequality M
Therefore, you should connect M with x≤-12.
- Inequality Y
Therefore, you should connect Y with x≥9.
- Inequality C
Therefore, you should connect C with x≥7.
Thus, the sequence is:
M -
C -
Y-
H-
W-

Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × ×
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × ×
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × + 15C5 ×
P = ( 15C8 + 15C5 )
P = ( (
) + (
) )
P = ( 6435 + 3003 )
P = ( 9438)
P = ( 4719)
P =
P = 0.29
