The probability of pulling out a red marble 3 times in a row will be 1/64.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Marbles: You have a bag with 3 red marbles, 4 blue marbles, and 5 green marbles.

Then the probability of pulling out a red marble 3 times in a row will be

The total number of events will be

Total events = 3 + 4 + 5 = 12

The favorable event will be

Favorable event = 3

Then the probability will be

P = (3/12)(3/12)(3/12)

P = (1/4)(1/4)(1/4)

P = 1/64

The solutions of the equation given as |2/3x + 2| − 8 = 0 are x = 9 and x = -15

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

to determine the solutions of the equation:

The equation is given as:

|2/3x + 2| − 8 = 0

Start by adding 8 to both sides of the equation.

So, we have

|2/3x + 2| = 8

Next, we remove the absolute value expression

So, we have;

2/3x + 2 = 8 and 2/3x + 2 = -8

Subtract 2 from both sides of the equation

2/3x = 6 and 2/3x = -10

Multiply the equation by 3/2

x = 9 and x = -15

Hence, the solutions of the equation given as |2/3x + 2| − 8 = 0 are x = 9 and x = -15

Ox= -9 and x = 9

Ox= -15 and x = 4

Ox= -15 and x = 9

Ox= -15 and x = 15

Hence, The value of x in the congruent triangles abc and dec is 1

the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.

The question implies that the triangles abc and dec are congruent triangles.

The congruent sides are,

ab = de

bc = ce = 4

ac = cd = 5

The congruent side ab = de implies that,

4x - 1 = x + 2

Collect like terms,

4x - x = 2 + 1

Evaluate the like terms,

3x = 3

Divide through by 3

x = 1

Hence, the value of x is 1

The standard form of the expression (6.8x10³)x(1.3x10⁻³) is 8.84 × 10⁰.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

Mathematical expression:

= (6.8x10³)x(1.3x10⁻³)

= 6.8x1.3

= 8.84

= 8.84 × 10⁰

Answer:

The club has 56 members

Step-by-step explanation:

We can set up a ratio problem to find the total number of kids in the club. There are two ways to do this, and I will show you both. The first way is to immediately set up a ratio between the number of boys and the number of total members in the club. Since the ratio of girls to boys is 6:2, the ratio of boys to members is 2:8 (add the number of girls and boys in the ratio to get the total number of people). Now, we can set up an equation, letting x equal the number of members total, and solve using cross multiplication:

[tex]\frac{2}{8}=\frac{14}{x}\\\\ 112=2x\\\\ x=56[/tex]

The other way to solve this problem would be to figure out the number of girls in the club if there are 14 boys and then add the two quantities together. If we let y be the number of girls in the club, we get the following solution:

[tex]\frac{6}{2}=\frac{y}{14}\\\\ 2y=84\\\\ y=42\\\\x+y=56[/tex]

Either way, we get that the total number of members is 56

Answer:

Firstly, we'll apply the below identity.

[tex]{\boxed{\sf{(a+b)^{2} = a^{2} + b^{2} +2ab}}}[/tex]

Applying the above identity.

⇒ (√5 + √2)²

⇒ (√5)² + (√2)² + 2×(√5)×(√2)

⇒ 5 + 2 + 2√10

⇒ 7 + 2√10

Comparing the LHS and RHS

⇒ 7 + 2√10 = a + b√10

∴ a = 7 and b = 2.

The correct options, in order, are:

[tex]f(n) = 3*(2)^{n-1}[/tex]

[tex]f(n) = 2*(6)^{n - 1}[/tex]

[tex]f(n) = 2*(4)^{n - 1}[/tex]

The first table is:

n   f(n)

1     3

2    6

3    12

Notice that when n = 1, all the exponents are 0, then the initial value is 3.

When n = 2, all the exponents are 1. Then we need to find the exponential equation with a base equal to 2.

So the exponential equation is:

[tex]f(n) = 3*(2)^{n-1}[/tex]

The second table is:

n   f(n)

1     2

2    12

3    72

By looking at the first pair, we conclude that the initial value is 2, and by looking at the second pair, we conclude that:

2*b = 12

b = 12/2 = 6

The base is 6.

So the exponential equation now is:

[tex]f(n) = 2*(6)^{n - 1}[/tex]

The last table is:

n   f(n)

1     2

2    8

3    32

Here we again have an initial value of 2, and the base is:

2*b = 8

b = 8/2 = 4

Then the correct option now is:

[tex]f(n) = 2*(4)^{n - 1}[/tex]

Applying the knowledge of fractions, the bigger one is: one-sixth of 138.

Fractions can be defined as a part of a digit or number, and are not whole numbers. For example, a third is 1/3, one-sixth is 1/6, which are both fractions.

Therefore, let's evaluate each statement:

1/3 of 45 = 1/3 × 45 = 15

1/6 of 138 = 1/6 × 138 = 23
