Answer:
Step-by-step explanation:
1/2 (n^3 - 1)
the difference means subtract
Answer:
its not bounded
Step-by-step explanation:
if a sequence is bounded both above and bounded below then we say its bounded. we can only conclude that 3.115 is either upper bound or the lower bound.
Answer:
Lower Quartile: 62
Upper Quartile: 81
Interquartile Range: 19
Step-by-step explanation:
To find the lower quartile, you want to find the median from the minimum to the median.
49, 55, 62, 64, 67
The median of this is 62. Therefore, 62 is the lower quartile.
To find the upper quartile, you want to find the median from the median to the maximum.
76, 79, 81, 82, 83
The median of this is 81. Therefore, 81 is the upper quartile.
To find the interquartile range, you subtract the upper and lower quartile.
81-62=19
The difference is 19. Therefore, the interquartile range is 19.
So what I think is that you multiply 4 by 4 or add 4 four times.Then, you would multiply 16 with 12 because there are 12 boxes and each box is 16. After doing that, you will get 192. Hope it helps :)
Answer:
Probability is 0.3506
Step-by-step explanation:
We are given
mean is 8mm
so, 
standard deviation is 2.2 mm
so, 
x-varies from 7mm to 9mm
At x=7:
we can use formula
we can plug values
At x=9:
we can use formula
we can plug values
So, z is between -0.45455 and 0.45455
now, we can use normal distribution table
and we get
Probability is 0.3506
