Answer: d. None of the above are correct.
Step-by-step explanation: Noise is a superfluous random alteration in an eletrical signal. There are different types of noises created by different devices and process. Thermal noise is one of them. It is unavoidable because is created by the agitation of the charge carriers, due to temperature, inside an eletrical conductor at equilibrium and is present in all eletrical circuits.
The formula to find the thermal noise power (N) is: N = 
.T.B, where:
is Boltzmann constant (1.38.
J/K);
T is temperature in Kelvin;
B is the bandwith;
Calculating the thermal noise power:
N = 1.38.·292·40
N = 16118.4. dBm
The thermal noise power [N] = 16118.4. dBm
Noise power density or simply Noise density (N₀) is the noise power per unit of bandwith and its SI is watts per hertz.
For thermal noise, N₀ = kT, where
<em>k </em>is the Boltzmann constant in J/K;
T is the receiver system noise temperature in K;
N₀ = 1.38. . 292
N₀ = 402.96. W/Hz
The thermal noise power density [N₀] = 402.96. W/Hz
in every die thrown 100 times a six occurs 32 times
so the probability of obtaining a die after 100 throws = 
-253 IS deeper than -280 in water. As your going into the negatives, The smaller numbers are bigger than the big numbers. It is the opposite when it comes to positive numbers.
Answer:
(8 (-1))
Step-by-step explanation:
Simplify the following:
8 (7 + 4×2 - 4 (11 - 7))
11 - 7 = 4:
8 (7 + 4×2 - 44)
4×2 = 8:
8 (7 + 8 - 4×4)
-4×4 = -16:
8 (7 + 8 + -16)
7 + 8 = 15:
8 (15 - 16)
15 - 16 = -(16 - 15):
8 (-(16 - 15))
| 1 | 6
- | 1 | 5
| 0 | 1:
8 (-1)
8 (-1) = (8 (-1)):
Answer: (8 (-1))
Answer:
Step-by-step explanation:
From inspection of the graph, we can see that the curve intercepts the x-axis at (-4, 0), (-1, 0) and (3, 0)
Therefore,
x = -4 ⇒ x + 4 = 0
x = -1 ⇒ x + 1 = 0
x = 3 ⇒ x - 3 = 0
Because (-4, 0) touches the x-axis, then (x + 4)² will be a factor
So (x + 4)², (x + 1) and (x - 3) are all factors of the polynomial
If we multiply the constants, this will give us the y-intercept:
⇒ 4² x 1 x -3 = -48
From inspection of the graph, the y-intercept is -6
So to get from -48 to -6 we need to multiply -48 by 1/8
Therefore, n = 1/8
