Answer:
The answer is C)
Step-by-step explanation:
Because -3 is between -2 and -4
Answer:
0.3
Step-by-step explanation:
Total number of cases = 60.
favourable number of cases = 18. (Since 18 of them are wearing green shirt)
As we know probability of an event is given by ,
P = Favourable number of cases divided by Total number of cases
Thus here,
P = 
= 
or 0.3
Answer: D
Step-by-step explanation:
The shorter leg equals to 8.
Answer:
Step-by-step explanation:
You'll need to find a way to share the graph or graphs associated with this problem.
The period is 4. The relationship between period and b (the coefficient of the independent variable of the cosine function) is (period) =(2π.b). Given that the period here is 4,
2π 2π
4 = ---------, and so b = ------- = π/2.
4
So now our y = a*cos (bx + c) becomes
π
y = 10*cos (------x + 0 + 10
2
The horizontal center line of this cosine curve is y = 10. The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.
