Answer:
Mean = 24
Variance = 107.78
Standard deviation = 10.38
Hope this helps! :)
I say 3 if I’m wrong sorry
Answer:
<h2>1 second.</h2>
Step-by-step explanation:
The graph is showing a periodic movement, which is the case of the movement of a pendulum. The x-axis represents the equilibrium point, that is y=0. So, each extreme point is where the pendulum immediately stops an return, So, we just have to observe what time it takes intercepting the axis twice in a row.
So, we see that at x=0.5, the pendulum is at equilibrium point, then at x=1.5 is crossing immediately again the equilibrium point. The time that took from 0.5 to 1.5 is 1 second, that is, 1.5-0.5 = 1 second.
Therefore, it takes 1 second to move from its resting point and return.
Answer:
Slope intercept form:y=mx+c
y=1/2x-7
Answer:
<em><u>M(-2,-6)</u></em>
y-axis (-2,6)
x-axis (2,-6)
<u><em>N(4,1)</em></u>
y-axis (4,-1)
x-axis (-4,1)
Step-by-step explanation:
When the point is reflected across the x-axis then the y value will change signs.
When the point is reflected across the y-axis then the x value will change signs
