Measurement error that is continuous and uniformly distributed from –3 to +3 millivolts is added to a circuit’s true voltage. Then the measurement is rounded to the nearest millivolt so that it becomes discrete. Suppose that the true voltage is 219 millivolts. What is the mean and variance of the measured voltage
Answer:
Mean = 219
Variance = 4
Step-by-step explanation:
Given
Let X be a random variable measurement error.
X has a discrete uniform distribution as follows
a = 219 - 3 = 216
b = 219 + 3 = 222
Mean or Expected value is calculated as follows;
E(x) = ½(216+222)
E(x) = ½ * 438
E(x) = 219
Variance is calculated as follows;
Var(x) = ((b-a+1)²-1)/12
Var(x) = ((222-216+1)²-1)/12
Var(x) = (7²-1)/12
Var(x) = 48/12
Var(x) = 4
Answer:
step 1. 6x2=12 first place way
step 2. 12×2=24
step 3. 24+6=30 second place way
First think out the equation, once you've done that multiply 3 by 25 to get 75
Here, Ratio of shadow to object = 253.1 / 42.9
So, it would remain constant for all objects.
Let, the show of women = x
Then, x / 6.2 = 253.1 / 42.9
x = 253.1 * 6.2 / 42.9
x = 36.58 Ft
In short, Your Answer would be 36.58 Feet
Hope this helps!
Answer:
13
Step-by-step explanation:
It should just be 104 divided by 8 which equals=13
