Answer:

False

Explanation:

Constellations are the group of stars with certain pattern. Constellations are seen during specific period of year due to revolution of earth around the Sun. Sun blocks some constellations during specific part of year, making them invisible from earth.

Example: Cygnus and Sagittarius are the summer constellations that are visible during summer months while Taurus and Orio are the winter constellations.

Consider the equation S + O2 ? SO2. What is the product? Question 3 options: S SO 2 S + SO 2 O 2

Keith_Richards [23]

Answer : The product in the given balanced reaction is, sulfur dioxide $(SO_2)$ .

Explanation :

The balanced chemical reaction will be,

$S+O_2\rightarrow SO_2$

This reaction occurs when sulfur react with oxygen gas to give sulfur dioxide gas as a product.

In the given balanced chemical reaction, sulfur (S) and oxygen gas $(O_2)$ are the reactants and sulfur dioxide $(SO_2)$ is the product.

Hence, the product in the given balanced reaction is, sulfur dioxide $(SO_2)$ .

Answer:

1) you're going to have to flip the coins (or fake numbers) for the experimental trials.

2) for the theoretical, there is 1/2 chance for heads or tails with each toss, so you'd expect that out of 10 tosses, 5 heads, 5 tails. out of 100 tosses- 50 heads, 50 tails.

When tossing 2 coins- 1/2×1/2 = 1/4 (25%) chance that 2 heads, 2 tails, or 1 heads & 1 tails. Deviation value comes from after you done your flipping and recorded your data. So if on 100 flips you actually got 50 and 50 (rarely us that exact ;), the deviation from the expected of 50/50 would be 0.00. If however you flipped 100 heads or 100 tails (impossible), then the deviation value would be 1.00.

|(100-50)| ÷ 50 = 50÷50 = 1.00

So usually you may have data like: 47/53 or something a little off than 50/50, making deviation |(47-50)| ÷ 50 = 3÷50 = 0.06.

Now the number of flips is important for the outcome! So if a coin toss if 10 times had 4 heads, 6 tails, the deviation value would be:

|(4-5)| ÷ 5 = 1÷5 = 0.20

So increasing the # flips DECREASES the deviation value!!

Whether it's from 10 to 100, or from 100 to 200. Look at my example of how the 10-flip deviation of 0.20 decreased to 0.06 with 100-flip

If I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from t

Natasha_Volkova [10]

The value of the unknown number is 10.5.

Let the unknown number = x

When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:

(x - 20)² = x² - 20

expand the equation;

x² - 40x + 400 = x² - 20

collect similar terms together;

x² - x² - 40x = -20 - 400

-40x = -420

$x = \frac{420}{40}\\\\ x = 10.5$

Thus, the value of the unknown number is 10.5.
