Answer:
Choice A. P = I² · R where
- P is the power in the DC circuit,
- I is the current through the circuit, and
- R is the total resistance of the circuit.
Step-by-step explanation:
Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work that the electrical force do when it moves charges across a potential difference :
W = .
The power is the rate at which the electrical force do the work:
.
On the other hand, current is the charge through a cross-section of the circuit in unit time. By the definition of current:
.
.
Consider Ohm's Law:
.
Therefore
.
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The capacity of an Airliner is k = 300 passengers
The sample size n = 320 passengers
The probability the a randomly selected passenger shows up on to the airport
Generally the mean is mathematically represented as
=>
=>
Generally the standard deviation is
=>
=>
Applying Normal approximation of binomial distribution
Generally the probability that there will not be enough seats to accommodate all passengers is mathematically represented as
Here
=>
Now applying continuity correction we have
=>
=>
From the z-table
So
Answer:
The correct Answer to this question will be D, last option
Step-by-step explanation:
x = DVD boxes
y = Gaming boxes
3x + 1y = 48 pounds
Now lets count:
In the Last option we see that DVD boxes have the weight of 8 pounds per box so 3 times 8 = 24, In the last option we see that 1 gaming box weight's 24 pounds
now we add the pounds together 24 p + 24 p = 48 p
So the Answer to your question will be D ot the last option.
I hope it helped someone.
Can I have please have brainliest so people know what answer to choose)
Answer:
42 square feet
Step-by-step explanation:
10 ×3= 30
4×3=12 divided by two =6 ×2= 12
(multiply because there are two triangular ends)
12+30=42
