monitta3 years ago
3 0

Answer:

True

Explanation:

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction. An exothermic reaction is a term that describes a chemical reaction in which there is a net release of energy (heat).

Write the repeating decimal 0.625625625… as a fraction in simplest form.
Neporo4naja [7]

The repeating decimal 0.625625625 represented as a fraction in its simplest form is 1001001/1600000.

<h3>What is a fraction?</h3>

Fraction simply refers to number expressed as a quotient, in which a numerator is divided by a denominator.

For example, a/b

Given that;

  • Decimal number = 0.625625625
  • Number in fraction form = ?

First, we rewrite the decimal number as a fraction with 1 in the denominator.

0.625625625 = 0.625625625/1

Next, we multiply to remove 9 decimal places. ( multiply top and bottom numbers with  1000000000 )

0.625625625 = 0.625625625/1 × 1000000000/1000000000

0.625625625 = 625625625/1000000000

Next, we simply, 625 can go through the numerator and denominator.

0.625625625 = 625625625/1000000000 = 1001001/1600000

Therefore, the repeating decimal 0.625625625 represented as a fraction in its simplest form is 1001001/1600000.

How did the results of the war with mexico help fulfill what many americans saw as their country's manifest destiny?
pogonyaev

In 1846, the United States and Mexico fought a war. Two years passed throughout the war. Mexico would lose nearly half of its territory to the United States by the end of the conflict, including areas from Texas to California.

Because it covered territory from the Atlantic to the Pacific, the war was a significant moment in American history as it fulfilled its "manifest destiny".

America was struck by the notion of "manifest destiny" in the 1840s, which held that the nation should extend from the Atlantic to the Pacific Ocean. The Oregon Territory, which was shared by the United States and Great Britain, and Mexico's western and southern holdings stood in the way of America's efforts to do this.

A bag contains chips of which 27. 5 percent are blue. A random sample of 5 chips will be selected one at a time and with replace
sineoko [7]

Answer:

No. of blue chips contain in a bag = P = 27.5 % = 0.27

No. of chips random selected at a time with replacement = n = 5

We know that the mean and standard deviation of the sampling distribution of the sample proportion  (p) is given by :-

\mu\-_pμ\-p = p

    = 0.275

\sigma_pσp = \sqrt{\frac{p (1-p)}{n} }np(1−p)

Where p= Population proportion and n = sample size.

Let p be the proportion of blue chips.

As per given , we have

p= 0.275

n= 5

= \sqrt{\frac{0.275 ( 1 - 0.275)}{5} }50.275(1−0.275)

= 0.1997
