Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles

Probability blue or red marble: 7/10

Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles

Probability non-blue or red marble: 3/10

What are the steps to solve this?<br> 9+6(x-5)=10-3(x-7)

Aliun [14]

<h2><u>Solve for x</u></h2>

<h3>what are the steps to solve this?</h3><h3>9+6(x-5)=10-3(x-7)</h3>

<u>Step 1:</u> Apply distributive property.

9 + 6(x - 5) = 10 - 3(x - 7)
9 + 6x - 30 = 10 - 3x + 21
-21 + 6x = 31 - 3x

<u>Step 2:</u> Combine all like terms.

-21 + 6x = 31 - 3x
-21 - 31 = -6x - 3x
-52 = -9x

<u>Step 3:</u> Divide both sides of the equation by -9 and simplify.

-52/-9 = -9x/-9
52/9 = x

<u>Answer:</u>

The value of x is <u>52/9</u>.

8^3*8^-5*8^y=1/8^2, what is the value of y in the product of powers below?

Aleks04 [339]

For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:

$a ^ n * a ^ m = a ^ {n + m}$

So, we can rewrite the given expression as:

$8 ^ {3-5 + y} = \frac {1} {8 ^ 2}\\8 ^ {- 2 + y} = \frac {1} {8 ^ 2}$

So, if $y = 0$ :

$8 ^ {- 2} = \frac {1} {8 ^ 2}\\\frac {1} {8 ^ 2} = \frac {1} {8 ^ 2}$

Equality is met!

Answer:

$y = 0$

In a relay race, the probability of the Galaxy team winning is 22%. In another unrelated relay race, the probability of the Kome

Shalnov [3]

Answer: There is probability of approximately 12% that Komets losing their race and the Galaxy winning their game.

Explanation:

Since we have given that

Probability of the Galaxy team wins = 22%

Probability of the Komets team wins = 47%

So, Probability of the Komets losing their race is given by

$100-47=53\%$

We need to find the probability of the Komets losing their and the Galaxy winning their game .

Let Event K : Komets losing their game

Event G : Galaxy winning their game

Since these are two independent events,

So,

$P(K\cap G)=P(K).P(G)\\\\P(K\cap G)=0.22\times 0.53\\\\P(K\cap G)=0.1166=0.12=12\%$

So, there is probability of 12% that Komets losing their race and the Galaxy winning their game.
