Magnetic fields can be used to make electricity
The properties of magnets are used to make electricity. Moving magnetic fields pull and push electrons. ... Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current

Answer:

Yes. That's how a magneto on a small lawn mower creates the spark for the spark plug. A magnet passes a coil and energizes the coil to produce electricity.

A park is in the shape of a rectangle. The park is 5/8 mile long and 2/3 mile wide. What is the area of the park?

Elenna [48]

To find the area of a rectangle, you times the length and width together.
So in this case,
5/8 x 2/3 = 10/24.
This can be simplified to 5/12

A company receives shipments of a component used in the manufacture of a component for a high-end acoustic speaker system. When

Tanya [424]

Answer:

$ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434$

Step-by-step explanation:

For this case we have a sample size of n = 250 units and in this sample they found that 24 units failed one or more of the tests.

We are interested in the proportion of units that fail to meet the company's specifications, and we can estimate this with:

$\hat p = \frac{24}{250}= 0.096$

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The confidence interval for a proportion is given by this formula

$\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}$

For the 98% confidence interval the value of $\alpha=1-0.98=0.02$ and $\alpha/2=0.01$ , with that value we can find the quantile required for the interval in the normal standard distribution.

$z_{\alpha/2}=2.33$

And the margin of error would be:

$ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434$

1. Which function describes the sequence 2,4,6,8......? *

Lyrx [107]

Answer:

$f(1) = 2$

$f(n) = f(n-1) + 2$ where $n\geq 2$

Step-by-step explanation:

Given

2,4,6,8...

Required

Which function determines the sequence

Represent the terms with n where n is 1,2,3....

Analyzing each term:

$f(1) = 2$

$f(2)= 4 = 2 + 2 = f(1) +2$

$f(3)= 6 = 4 + 2 = f(2) +2$

$f(4)= 8 = 6 + 2 = f(3) +2$

Notice that each term is an addition of the previous term and 2

In other words:

$f(n) = f(n-1) + 2$

However, the function is only effective for values of n greater than or equal to 2

So: $n\geq 2$

Sav [38]

Using the binomial distribution, it is found that there is a 0.9842 = 98.42% probability that 3 or fewer experienced insomnia as a side effect, which means that it is a highly likely event.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
