Answer:

The probability can be written as;

3/10

0.3

30%

Step-by-step explanation:

To determine the probability, we will find: (the number of favourable outcomes) / (the number of possible outcomes).

The favourable outcome is 3, because there are 3 blue marbles.

The possible outcome in 10, because there are 10 total marbles.

The probability is 3/10.

Let's divide: 3 ÷ 10 = 0.30

There is a 30% chance of drawing a blue marble.

Answer:

<em>The probability is 3 out of ten / </em><em><u>3/10 </u></em>, 0.3 , or 30%

Step-by-step explanation:

So suppose you have 10 marbles infront you

Four of them are RED   ΘΘΘΘ

Three of them are BLUE ΘΘΘ

Two of them are White  ΘΘ

One of them is yellow   Θ

We only need the probability for the blue marbles

Lets look at the blue marbles out of every other colored marble

There is ΘΘΘ (3) BLUE MARBLES out of the other 10 '

So the answer is 3 out of 10.

murzikaleks [220]

Answer:

x<5/2

Step-by-step explanation:

We have

2x−3<2

Add 3 to both sides.

2x−3 +3 <2 +3

which makes

2x<5

Divide both sides by 2.

2x/2 < 5/2

x<5/2

3^3x+1= 81<br> Solve the exponential function
Reil [10]

Answer:

x=1

Step-by-step explanation:

3^ (3x+1) = 81

Rewrite 81 as a power of 3

3^4

3^ (3x+1) = 3^4

Since the bases are the same, the powers are the same

3x+1 =4

Subtract 1 from each side

3x+1-1 =4-1

3x=3

Divide by 3

3x/3 = 3/3

x =1

36 divided by 6+(18-6x2)
Ipatiy [6.2K]

Answer:

12.

Step-by-step explanation:

This equation seems to want you to use the Order of Operations, a.k.a PEMDAS (which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). When you do a problem like this, you use the Order of Operations to figure out the order in which you'd solve your problem.

You would first solve what is in parentheses, since that is the first letter in PEMDAS. 18-6x2 is what we have in our parentheses, but it's too confusing to be solved yet. The next letter is E, a.k.a exponents, but there are no exponents in this equation, so we move on. Next is M, Multiplication. We would multiply 6 by 2, which gives us 12. Moving on, we have D, Division. We would do 36/6, which is 6.

Our 5th letter is A, Addition. We would have to add our 6 to (18-12), but that couldn't work, since our 18-12 is still in parentheses, and those come first. So, we would skip to the last letter, S, Subtraction. 18-12=6, and since we solved all the problems in the parentheses, we remove them, and add both 6's together, giving us 12.

Simplify as much as possible:<br> (7nm5o2) (-3m3o5)2
Yakvenalex [24]

Answer:

63m^11 no^12

Step-by-step explanation:

Dont know if thats o or and zero but I solve it by using o..if it was a zero then comment that so I can redo it anyways heres the explanation

(7nm^5 o^2) × (-3m^3 o^5)^2

7m^5 no^2) ×(-3m^3 o^5) ^2

(7m^5 no^2) × (3m^3 o^5)^2

7m^5 no^2 × (3m^3 o^5) ^2

7m^5 no^2 × 9m^6 o^10

63m^11 no^12
