Answer:
and
Step-by-step explanation:
We have to write a multiplication equation and a subtraction equation that both involve a fraction and have the same solution.
Let the multiplication equation be, .
And the subtraction equation is,
Now, and
Therefore, in both the equations the solution is . (Answer)
Correct, all decimals and fractions are rational numbers.
The length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.
<h3>What is an ampere circuit?</h3>
Ampere's circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.”
Here we have a cable rating of 120-volt/15-amp so if the 1-ampere circuit means 1 watt per foot cable will be used for the 1-ampere circuit.
A Total of the 15-ampere circuit means 15 watts needed so we are using 2.5 watts per foot.
Hence the length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.

Answer:
B. 0.0028
Step-by-step explanation:
This is a binomial distribution. We could use a calculator to find the probability, or, since the sample size is large enough and both np and nq are larger than 10, we can approximate this as a normal distribution.
To do so, we first find the mean and standard deviation.
μ = np = (0.02) (1500) = 30
σ = √(npq) = √(0.02 × 0.98 × 1500) = 5.42
Now we find the z-score:
z = (x − μ) / σ
z = (45 − 30) / 5.42
z = 2.77
Finally, we use a z-score table to find the probability.
P(z > 2.77) = 1 − P(z < 2.77)
P(z > 2.77) = 1 − 0.9972
P(z > 2.77) = 0.0028
Answer: It equals y to the twentieth power.
Step-by-step explanation: when you have a power to a power, like this example, it's essentially saying, y to the power of 4 times y to the power of four times times y to the power of 4 times y to the power of 4 times y to the power of 4, so y to the fourth is being repeated 5 times, so just multiply 5*4 to get 20.
