-10 and 10 are 10 units from 0 on the number line

Answer: Option C

2,400

Step-by-step explanation:

When launching the first 6-sided die there are 6 possible outcomes

When launching the 4-sided die there are 4 possible outcomes

When throwing each die of 10 faces there are 10 possible outcomes

So if all the dice are thrown together, the number of possible combinations that can be obtained is:

[tex]S = 6 * 4 * 10 * 10\\S = 24 * 100[/tex]

[tex]S = 2400[/tex] possible results

Finally the answer is the option C.

Answer:

V = 11

Step-by-step explanation:

All you have to do here is to multiply both sides of this equation by 13.  This will eliminate the fractions.  You'll be left with V = 11.

To solve the proportion V/13 = 11/13, we can equate V to 11 since identical denominators imply equal numerators. No further calculations or rounding needed as V is a whole number.

To solve the proportion V/13 = 11/13 for V, we can see that both sides of the equation are divided by the same number, 13. Since the denominators are equal, we can deduce that the numerators must also be equal for the proportion to be true.

Therefore, the value of V must be equal to 11, as V/13 matches 11/13. There is no need for further calculations or rounding since 11 is already a whole number.

x = - [tex]\frac{11}{8}[/tex]

Step-by-step explanation:

Given

(x - 4) - (x + 7 ) = 8x

Distribute parenthesis noting second is distributed by - 1

x - 4 - x - 7 = 8x ← simplify left side

- 11 = 8x ( divide both sides by 8 )

x = - [tex]\frac{11}{8}[/tex]

Answer:

By definition of multiplication of powers of the same base we have to put the same base and add the exponents, then, we can rewrite the expression as:

[tex](2 ^ {\frac {1} {2} + \frac {3} {4}}) ^ 2 =\\(2 ^ {\frac {4 + 6} {8}}) ^ 2 =\\(2 ^ {\frac {10} {8}}) ^ 2 =\\(2 ^ {\frac {5} {4}}) ^ 2 =[/tex]

By definition of power properties we have to:

[tex](a ^ n) ^ m = a ^ {n * m}[/tex]

So, we have:

[tex]2 ^ {\frac {10} {4}} =\\2 ^ {\frac {5} {2}} =[/tex]

By definition of properties of powers and roots we have:

Option B

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 5y + 2x = 12 into this form

Subtract 2x from both sides

5y = - 2x + 12 ( divide all terms by 5 )

y = - [tex]\frac{2}{5}[/tex] + [tex]\frac{12}{5}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{2}{5}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{5} }[/tex] = [tex]\frac{5}{2}[/tex] → A

The sample standard deviation is 14.458

The population standard deviation is 13.967

Step-by-step explanation:

* Lets revise the population standard deviation (σ)

1. Work out the Mean (μ) (average of the numbers)

2. Then for each number subtract the Mean and square

   the result  (xi - μ)²

3. Then work out the mean of those squared differences

    [∑(xi - μ)²/N]

4. Take the square root of that (√[∑(xi - μ)²/N]) and to find σ

* Lets revise the sample standard deviation (s)

1. Work out the Mean (x) (average of the numbers)

2. Then for each number subtract the Mean and square

    the result  (xi - x)²

3. Then work out the mean of those squared differences [∑(xi - x)²/N - 1]

4. Take the square root of that (√[∑(xi - x)²/N - 1]) and to find s

* Now lets solve the problem

- The data are 15 numbers

  17 , 37 , 56 , 16 , 12 , 16 , 19 , 45 , 14 , 37 , 21 , 26 , 43 , 46 , 42

∵ x = μ = sum/number

∴ x = μ = (17+37+56+16+12+16+19+45+14+37+21+26+43+46+42)÷15=29.8

- Subtract the mean from each number and square the result

∵ (17 - 29.8)² = 163.84

∵ (37 - 29.8)² = 51.84

∵ (56 - 29.8)² = 686.44

∵ (16 - 29.8)² = 190.44

∵ (12 - 29.8)² = 316.84

∵ (16 - 29.8)² = 190.44

∵ (19 - 29.8)² = 116.64

∵ (45 - 29.8)² = 231.04

∵ (14 - 29.8)² = 249.64

∵ (37 - 29.8)² = 51.84

∵ (21 - 29.8)² = 77.44

∵ (26 - 29.8)² = 14.44

∵ (43 - 29.8)² = 174.24

∵ (46 - 29.8)² = 262.44

∵ (42 - 29.8)² = 148.84

∴ ∑(xi - μ)² = ∑(xi - x)² = 2926.36

∵ N = 15

∴ The sample standard deviation = √[∑(xi - x)²/(N - 1)]

∴ s = √[2926.36/(15 - 1)] = 14.458

∴ The population standard deviation = √[∑(xi - μ)²/N]

∴ σ = √[2926.36/15] = 13.967

When we have 2 points, we can find the slope using

m = (y2-y1)/(x2-x1)

Substituting what we know

1/5 = (0-3)/(x--2)

1/5 = -3/(x+2)

Using cross products

1*(x+2) = 5*(-3)

x+2 = -15

Subtract 2 from each side

x+2-2 = -15-2

Step-by-step explanation:

all y components

same y value are not repeated

Final answer:

The coordinates of the point are (4, 3), where 4 is the x-coordinate (horizontal direction) and 3 is the y-coordinate (vertical direction).

Explanation:

The coordinates of a point on a Cartesian coordinate system are determined by its horizontal position (x-coordinate) and its vertical position (y-coordinate). Given that the point is on the first coordinate axis (x-axis) and in the (1, 2)th coordinate plane, we understand that the x-coordinate is related to the horizontal direction and the y-coordinate is related to the vertical direction.

In the context of this problem, if the figure on the coordinate plane indicates that the point is 4 units to the right of the origin along the x-axis and 3 units above the origin along the y-axis, then the coordinates of the point are ( extbf{4},  extbf{3}). Here, the convention is that moving to the right of the origin increases the x-coordinate and moving upwards increases the y-coordinate.

The simplified form of the expression [tex]\( \frac{x + 4}{x^2} \div \frac{2}{x} \) is \( \frac{x + 4}{2x} \).[/tex]

To simplify the given expression, we'll first deal with the division of fractions by turning it into multiplication with the reciprocal of the divisor.

So, the given expression [tex]\( \frac{x + 4}{x^2} \div \frac{2}{x} \)[/tex] becomes:

[tex]\[ \frac{x + 4}{x^2} \times \frac{x}{2} \][/tex]

Next, let's factor the numerator x+4 and simplify:

[tex]\[ \frac{x + 4}{x^2} \times \frac{x}{2} = \frac{x + 4}{x^2} \times \frac{x}{2} = \frac{(x + 4) \cdot x}{x^2 \cdot 2} \][/tex]

Now, we'll simplify the expression by canceling out common factors:

[tex]\[ = \frac{x(x + 4)}{2x^2} \]\[ = \frac{x(x + 4)}{2x^2} = \frac{x(x + 4)}{2x \cdot x} \][/tex]

[tex]\[ = \frac{x + 4}{2x} \][/tex]
