True Or False?

Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
Answer: A. True

Total amount of money paid
=11 x 15
=$165

total amount of money sold
=25 x 15
=$375

difference
= 375 - 165
=$210

What is the slope between the points (8, -2) and (-7, 10)

lara [203]

Slope formula:
(y2-y1)/(x2-x1)

Substitute in the points into the slope formula.

Slope= [10-(-2)] / [(-7)-8]
Slope= (10+2) / (-15)
Slope= 12/-15
Slope= -12/15
Simplify (3 goes into each)
Slope= -4/5

Hope this helps!! :)

Considering the Central Limit Theorem, we have that:

a) The probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.

b) The probability can be calculated, as the sample size is greater than 30.

<h3>What does the Central Limit Theorem state?</h3>

It states that the sampling distribution of sample means of size n is approximately normal has standard deviation $s = \frac{\sigma}{\sqrt{n}}$ , as long as the underlying distribution is normal or the sample size is greater than 30.

In this problem, the underlying distribution is skewed right, that is, not normal, hence:

For item a, the probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.

For item b, the probability can be calculated, as the sample size is greater than 30.
