The sample space when one marble is to be chosen is given as  s = {purple, pink, red, blue, green, orange, yellow}

A set of potential outcomes from a random experiment is known as a sample space. The sample space is identified by the letter "S." Events are a subset of the potential outcomes of an experiment. The results in a sample area could vary depending on the experiment. There are only a finite number of possible outcomes in discrete or finite sample spaces.

The sample space in the question has been listed according to the colors of the offered marbles. Finding the sample whose result is a specific stone is necessary. As a result, each color of the marble will be taken into account once.  Therefore, the sample space becomes  s = {purple, pink, red, blue, green, orange, yellow}

The value of x in the algebraic equation '6/9 = x/6' is 4

An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other. The algebraic equation usually consists of a variable, coefficients and constants.

For example 5x+6 = x is an algebraic equation where 5 and 1 are the coefficient of x at the L.H.S and R.H.S respectively. And x is the variable.

in the equation 6/9 = x/6. This equation is an algebraic equation with fraction.

We solve by multiplying both side by the L.C.M which is 18

6/9× 18 = x/6 × 18

12 = 3x

divide both sides by 3

x = 12/3 = 4

Step-by-step explanation:

To find the number that when multiplied with -9/13 gives the product 45, you can divide 45 by -9/13. Dividing 45 by -9/13 is the same as multiplying -9/13 by the reciprocal of 45, which is -1/45. The reciprocal of a number is 1 divided by that number, so the reciprocal of 45 is 1/45.

Therefore, the number you are looking for is -1/45. When multiplied by -9/13, this number gives the product 45:

(-1/45) * (-9/13) = (-1 * -9) / (45 * 13) = 9/585 = 45

It is 20% because there is 5 squares. So we need to make this a fraction. So the fraction would be 1/5.  So we then have to find a multiple  for 1/5 because it is out of 100. So 20x5=100. So we have to multiply the top and the bottom part of the fraction by 20. So 5x20=100 and 1x20=100. So then we get 20/100. So the top number is your percent. So 20% is your answer. Good luck.

The side lengths of the triangle are 27 cm, 36 cm, and 45 cm.

Let x = length of the longer leg of the triangle

If the shorter leg of a right triangle is 9cm shorter than the longer leg, then

length of the shorter leg of the triangle = x - 9

If the hypotenuse is 9cm longer than the longer leg, then

length of the hypotenuse of the triangle = x + 9

Use Pythagorean theorem to solve for the side lengths of the triangle. Pythagorean theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

(x + 9)² = x² + (x - 9)²

Simplify the equation and solve for x.

(x + 9)² = x² + (x - 9)²

x² + 18x + 81 = x² + x² - 18x + 81

36x = x²

x² - 36x =0

x(x - 36) = 0

x = 36

length of the longer leg of the triangle = x = 36 cm

length of the shorter leg of the triangle = x - 9 = 36 - 9 = 27 cm

length of the hypotenuse of the triangle = x + 9 = 36 + 9 = 45 cm

Using mathematical operations, the greatest number of songs Aerabella can play at her Sweet 16 party is 106.

The number of songs Aerabella can play is determined by subtracting the fixed charge for the day from her spending budget and dividing the difference by the unit charge per song.

Subtraction and division operations are two of the four basic mathematical operations, including addition and multiplication.

The total spending budget = $130

The fixed rental charge for a DJ = $50

The charge per song (unit rate) = $0.75

The variable cost for the party = $80 ($130 - $50)

The number of songs Aerabella can play = 106.67 ($80 ÷ $0.75)

Line: Dashed

Shade: Below

m = -3/4

b = 3

(0,3) - False - No

(2,4) - True - Yes

(-1,-2) - False - No

Step-by-step explanation:

Given:

-3x < 4y - 12

Questions:

Line: Solid or Dashed?

Shade: Above or Below?

m=

b=

Are these points solution:

Solve:

Inequalities that use '< or >' symbols are plotted with a dashed line. Due to that dashed line means the solution doesn't include the line itself.

< = Less than

> = Greater than

Inequalities that use '≤ or ≥' symbols are plotted with a solid line. Due to that solid line means the solution does includes the line itself

≤ = Less than or equal to

≥ = Greater than or equal to

Therefore, based on the given, the line is Dashed. Which also means the solution doesn't includes the line itself.

We also know that the given info with the inequalities of "<".

"<" Means Less than which means shade below. If it was "> " which means greater than you have to shade above.

To find the m and b we first have to know that;

y = mx + b

m = Slope

b = y-intercept

To find the Slope(m) and b(y-intercept) we first have to put -3x < 4y - 12  in  slope-intercept form.

-3x < 4y - 12

y > -3/4x + 3

Hence,

m = -3/4

b = 3

To see if the following points {(0,3) (2,4) (-1,-2)} are solutions for -3x <4y-12

All we have to do is to substitute it in.

Starting with (0,3)

x = 0

y = 3

-3(0) < 4(3) - 12

0 < 0

False. 0 isn't less than 0- it equal to 0. Hence it isn't a solution to -3x < 4y - 12

Next (2,4)

x = 2

y = 4

-3(2) < 4(4) -12

-6 < 4

True. -6 is less than 4. Hence it is a solution to -3x < 4y - 12

Finally, we have (-1,-2)

x = -1

y = -2

-3(-1) < 4(-2) -12

3 < -20

False. 3 isn't less than -20. Hence it isn't a solution to -3x < 4y -12

Step-by-step explanation:

Answer:

There are three integers are there in the above list

The slope of the line that passes through the points (2, 3) and (0, 11) is -4.

Slope of line is calculated by the formula m = (y2-y1)/(x2-x1).

In this case, x1 = 2, y1 = 3, x2 = 0 and y2 = 11.

Plugging in the values gives us:

m = (11-3)/(0-2)

We can simplify this expression by multiplying the numerator and denominator by -1:

m = (-11+3)/(-2-0)

This simplifies to:

m = 8/-2

Finally, we can simplify the fraction to:

m = -4

Therefore, the slope of the line that passes through the points (2, 3) and (0, 11) is -4.

If two groups of numbers have the same mean, then other measures of location need not be same. The Sample Mean is always smaller than the mean of the population from which the sample was taken.

Mean: It is the most commonly used measure of central tendency. It actually represents the average of the given collection of data. It is applicable for both continuous and discrete data.

Median: Given that the data collection is arranged in ascending or descending order, the following method is applied:

If two groups of numbers have same mean that does not imply they will have same std deviation, median and mode. Even if two groups have same mean other measures may not be same because one group might be more or less scattered than the other group and though they may have same mean.

So the correct answer is option A.

Other measures of location need not be same.

2. Here, the correct option is option d. This is because when we calculate mean we basically take the average of each and every value in the given sample, which is bound to lie between the maximum and minimum value.

A mean can be zero if it has equal positive and negative numbers and a mean can be negative if it has more negative numbers. Again the mean of the sample is not always necessarily smaller than the mean of the population of which the sample is a part. Hence the first three options are incorrect

Therefore,  the correct option is option d. Mean is always smaller than the mean of the population from which the sample was taken.

The formula for the distance d between two points on the coordinate plane is; [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The midsegment of a trapezoid is the segment that joins or extends between the midpoints of the sides of the trapezoid that are not parallel.

The parallel sides are the sides that have the same slope;

Slope of the side EF = (5 - 6)/(-2 - (-7)) = -0.2

Slope of the side FG = (5 - 2)/(-2 - (-2)) = Undefined

Slope of the side GH = (-4 - 2)/(-7 - (-2)) = 1.2

Slope of the side EH = (-4 - 6)/(-7 - (-7)) = Undefined

The non parallel sides are EF and GH

The midpoint of EF = ((-7 + (-2))/2, (6 + 5)/2) = (-4.5, 5.5)

The midpoint of GH = ((-7 + (-2))/2, (2 + (-4))/2) = (-4.5, -1)

The length of the mid segment is therefore;
