Answer:
Step-by-step explanation:
amplitude of oscillation a = 12 / 2 = 6 inches.
time period T = 2 s
b = angular frequency = 2π / T
= 2π / 2
= π
so putting the values in the equation
d = a cos ( b t )
d = 6 cos ( π t )
Answer:
She'd have to work for 12 hours.
Step-by-step explanation:
100 ÷ 9 = 11.11
Rounded up its 12
It's c. the only way he can compare both is by calculating both groups' mean and comparing it. Randomizing wont work because it is mixing both protein bar users and non-protein bar players.
Answer:
2400
Step-by-step explanation:
40 = 2^3 * 5
120 = 2^5 * 5
150 = 2 * 3 * 5^2
LCM = 2^5 * 3 * 5^2
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
