Answer:
B. 7 to the right of the 9
9+(-7)
=9-7=2
so, the 7 is on the right side of 9
Answer: The required time is 0.743.
Step-by-step explanation:
Since we have given that
We need to find the time above which is 68% of the cameras have to be reset.
So, exponential distribution would be
So, it becomes,
Hence, the required time is 0.743.
C because it would be 13 x 3 and then you would take that result and times it by 3 and so on and so on and this eventually after 10 hours results to C

Median
Median is the mean of 18 and 32 because they are in the middle, so it's 25. Median is the best representation because most numbers are around 20-30. 115 makes the mean go super high, which is not good, 11 drags the mean down, which is not good either.
Extras:
Mean: 11+11+18+32+34+115 =
221 divided by 6 =
36.88
Answer:
y = 0.5cos(4(x+π/2)) -2
Step-by-step explanation:
The centerline of the oscillation is at -2, so only the 2nd and 4th choices are viable.
The multiplier of x is computed from (2π)/period. One period is π/2, so the multiplier of x is ...
... 2π/(π/2) = 4 . . . . . matching the 2nd selection.
The horizontal offset in the second equation (π/2) is of no consequence, as it is one full period of the function.
The peak-to-peak amplitude of the oscillation is 1 unit, so the multiplier of the cosine function (which usually has a peak-to-peak value of 2 units) is 0.5. Every offered answer has that characteristic.
The appropriate choice is the 2nd one:
... y = 0.5cos(4(x+π/2)) -2
