The probability of taking out a pencil from the bag having 9 pens, 7 pencils and 6 crayons is 0.32.

We are given that:

We have-

Number of pens = 9

Number of pencils = 7

Number of crayons = 6

Now, the total number of objects in the bag = 9 + 7 + 6

Now, the total number of objects in the bag = 22

We have to find the probability of taking out a pencil from the bag.

P ( taking out a pencil from the bag ) = 7 / 22

P ( taking out a pencil from the bag ) = 0.32

Therefore, we get that, the probability of taking out a pencil from the bag having 9 pens, 7 pencils and 6 crayons is 0.32.

Answer:

d=1, 1+12=13 Variable can be a number or any number .

Option 2, (x, y) --> (x + 3, y - 2) is the algebraic expression that shows how the translation affects the coordinates of the preimage.

Here, we are given that a figure is translated 3 units to the right and two units down.

Now, if the original coordinates of the figure are (x, y), as given in all the options, let us look at the effect of the transformation.

3 units right the x coordinate will increase by 3 units

thus x becomes (x + 3)

2 units down = the y coordinate will decrease by 2 units

thus y becomes (y - 2)

Hence, the new coordinates of the figure become {(x + 3), (y - 2)} Therefore, option 2, (x, y) --> (x + 3, y - 2) is the correct answer.

Answer:

x = 11

Step-by-step explanation:

3x = 2 + 31​

To find the value of x, combine like terms

3x= 33

Divide each side by 3

3x/3 = 33/3

x = 11

Find the value of x.

3x = 2 + 31

x = 11

=> 3x = 2 + 31

First, add the like terms.

=> 3x = 33

Transfer 3 to RHS

=> x = 33/3

Divide 33 by 3

=> x = 11

Answer:

1.  y-intercept = 5

2.  x-intercept = -2.5

3.  slope = 2

4.  y = 2x + 5

Step-by-step explanation:

Part 1

The y-intercept is the point at which the line crosses the y-axis, so when x=0.  From inspection of the given graph, the y-intercept is 5.

Part 2

The x-intercept is the point at which the line crosses the x-axis, so when y=0.  From inspection of the given graph, the x-intercept is -2.5.

Part 3

The slope of the line is the measure of its steepness.  To find the slope of a line, substitute two points on the line into the slope formula.

Two points on the line are the y-intercept and the x-intercept:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-5}{-2.5-0}=\dfrac{-5}{-2.5}=2[/tex]

Therefore, the slope of the line is 2.

Part 4

Slope-intercept form of a linear equation:

[tex]\boxed{y=mx+b}[/tex]

Where:

Substitute the found slope and y-intercept from Part 3 and Part 1 into the formula to create an equation for the line:

[tex]y=2x+5[/tex]

The solution is 9.

To find the solution, firstly rewriting the given equation -

√(5x+4) - √x = 4

Now, shifting √x from Left Hand Side to Right Hand side of the equation. Rewriting the equation -

√(5x+4) = √(x) + 4

Taking square of complete equation

(√(5x+4))² = (√(x) + 4)²

Solving the square of equation

5x + 4 = x + 16 + 8√x

Simplifying the equation

5x - x - 8√x = 16 - 4

4x - 8√x = 12

Rewriting the equation

4x - 12 = 8√x

Again taking square on both sides

(4x - 12)² = (8√x)²

16x² + 144 - 2×4x×12 = 64x

16x² + 144 - 96x = 64x

16x² + 144 - 96x - 64x = 0

16x² + 144 - 160x = 0

Dividing the equation by 16

x² + 9 - 10x = 0

x² - 10x + 9 = 0

x² - 1x -9x + 9 = 0

x(x - 1) -9(x - 1) = 0

(x - 1) (x - 9) = 0

x = 1, 9

Keep the value of x in equation to find the solution

x = 1

√(5×1 + 4) - √1 = 4

√(5 + 4) - 1 = 4

√9 - 1 = 4

3 -1 = 4

2 ≠ 4

x = 9

√(5×9 + 4) - √9 = 4

√(45 + 4) - 3 = 4

√49 - 3 = 4

7 - 3 = 4

4 = 4

Hence, the solution is 9.

where, a is the base of function or equation

           x = expression or equation

Mathematically, if  [tex]a^N=x[/tex]  is an exponential function then, this can be converted to logarithmic function as  [tex]log_ax=N[/tex].

There are many formulas that are given to us for solving several simple and complex problems based on logarithmic functions and logarithmic equations.

Some important formulas of logarithms are :

We use the given formula:

[tex]m_2 - m_1 = -2.5 log \frac{b_2}{b_1}[/tex]

now m2 = 2.0 and m1 = 1.0

Hence,

[tex]m_2 - m_1 = -2.5 log \frac{b_2}{b_1}\\\\= > 2.0 - 1.0 = -2.5 log \frac{b_2}{b_1}\\\\= > -1.0 = -2.5 log \frac{b_2}{b_1}\\\\= > log \frac{b_2}{b_1} = 0.4\\\\= > \frac{b_2}{b_1} = 10^{0.4} = 2.5 approx.[/tex]

The equivalent equation for the given equation is 5n+10d=365. Therefore, option A is the correct answer.

The given equation is 0.05n + 0.1d = 3.65.

Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

Now, multiply by 100 on both sides of the given equation.

However, some authors define least common multiple(a,0) as 0 for all a, since 0  is that the  only common multiple of a and 0.

The least common multiple  is that the  "least common Denominator" (lcd) that can be used before fractions can be added, subtracted or compared.
