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.

A 26-feet board is cut into 3 lengths where the first length is x, the second piece is 3 feet less than twice the first and the
Gnom [1K]

We now have three equations, so we can solve them.

Let's define the length of the 3 boards in terms of x:

F=x

S=2x-3

T=2

F+S+T =26

x+2x-3+2 =26

3x =26+1=27

x =27/3 = 9 feet for First section

2x-3 =18-3 = 16 feet = Second

2 = Third

9+16+2 = 27

27 is the length of the shortest piece.

Does anyone know how to do 9 and 10 ???
I am Lyosha [343]
9.2x-9<7
add 9 to both sides, 2x<16
divide both sides by 2, x<8
A.

10.n<5
-4n+11>-9 Subtract 11 from both sides
-4n>-20 then, divide both sides by -4
In these greather than less than equations, when you divide a negative by another negative, you must flip the sign 
so that would be, n<5

Answer:

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified

Step-by-step explanation:

Given:

m angle 1 = ( 3x + 10 )°

m angle 2 = ( 5x - 4 )°

To Find:

m∠1 = ?

m∠2 = ?

Solution:

Vertical Angles:  

The angles opposite each other when two lines cross. They are always equal.

∴ m Angle 1 = m Angle 2

Substituting the given values we get

3x+10=5x-4\\\\2x=14\\\\x=\dfrac{14}{2}=7\\\therefore x =7

Substituting ' x ' in Angle 1 and Angle 2 we get

m Angle 1 = 3 × 7 + 10 = 31°

m Angle 2 = 5 × 7 - 4  = 31°

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified
