Answer: -120
Step-by-step explanation:
this would be the answer because if you take a positive and add it to a negative you get zero if their the additive inverse of the number.

Question has missing details (Full question below)
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:
is there supposed to be a picture that goes with this
Step-by-step explanation:
: 0
(new amount-old amount)=(198,000)-(100,000)=98% increase
98/5 years=19,600
Yr 1=$100,000+19,600=$119,600
Yr 2=$119,600+19,600=$139,200
Yr 3=$139,200+19,600=$158,800
Yr 4=$158,800+19,600=$178,400
Yr 5=$178,400+19,600=$198,000
The mortgage grew at a steady rate of $19,600 over the 5 years...
HOPE THIS HELPS :)
