Answer:
x28
Step-by-step explanation:
The point at 28 is solid, so it is included in the graph, so x=28, The line extends in the negative direction, with an arrow, is given by x<28. Taken together, x28.
The mean (average) of a data set is found by adding all numbers together and then dividing by the number of values in the set.
Median is the middle value when the numbers are ordered from least to greatest.
The volume of a cone is 1/3*(pie)*r^2*h
56.52=1/3*(pie)*r^2*6
Then divided 1/3 and pie to both side
56.52/1/3*pie=r^2*6
59.19=r^2*6
59.19/6=r^2
9.86=r^2
then square root the r
r=3.14
d=3.14*2
answer= 6.28
Answer:
−9.3x + 13.1y
Step-by-step explanation:
Answer:
Fs = 15 Hz > 12.7322 Hz
Hence, Nyquist theorem is NOT violated
Step-by-step explanation:
Given that;
a signal given by 15cos(20t) + 20sin(40t)
sampled at a rate of 15 Hz
Is the Nyquist theorem violated?
so;
from 15cos(20t) + 20sin(40t)
Freq F1 = 20/2π Hz
F1 = 3.1830 Hz
and
Freq F2 = 40/2π
F2 = 6.3661 Hz
Now, Nyquist's rate FN ≥ 2 × F_max
FN ≥ 2 × 6.3661
FN ≥ 12.7322 Hz
Now our given signal was sampled at a rate of 15 Hz
so, Fs = 15 Hz > 12.7322 Hz
Hence, Nyquist theorem is NOT violated
