There are 10 sweets in a bag.

Valentin [98]

Answer:

See Explanation Below

Step-by-step explanation:

Given

Total Sweets = 10

Red = 4

Green = 2

Yellow = 3

Purple = 1

Required

a & b

The question is not properly presented; however the solution is as follows;

Let P(Yellow) represent the probability of selecting a yellow sweet and n(Yellow) represent the number of Yellow sweets;

$P(Yellow) = \frac{n(Yellow)}{Total}$

$P(Yellow) = \frac{4}{10}$

$P(Yellow) = 0.4$

So, whichever letter that shows $0.4$ or $\frac{4}{10}$ is the probability of choosing a yellow sweet

Let P(Orange) represent the probability of selecting an orange sweet and n(Orange) represent the number of orange sweets;

Since, there's no orange sweet in the bag;

$n(Orange) = 0$

$P(Orange) = \frac{n(Orange)}{Total}$

$P(Orange) = \frac{0}{10}$

$P(Orange) = 0$

In probability; opposite probabilities add up to 1;

Let P(Not\ Orange) represent the probability of choosing a sweet that is not orange

$P(Not\ Orange) + P(Orange) = 1$

Substitute $P(Orange) = 0$

$P(Not\ Orange) + 0 = 1$

$P(Not\ Orange) = 1$

So, whichever letter that shows 0 is the probability of choosing a sweet that is not orange

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

Nitella [24]

The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.

<h3>What is an Algebra equation?</h3>

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.

Let the number be x.

If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².

And if I square my number that is x² then subtract 20 from the result that is x² - 20.

Both the result are the same then we have

(x - 20)² = x² - 20

x² - 20x + 100 = x² - 20

-20x + 100 = -20

x = 6

My number is 6
