According to the information, the line plots of points 6 and 7 have several values that are repeated more than once as shown in the graphs.

To make a line plot we must identify the values that we must locate on the number line. Once we know the values we must place a point or symbol above the corresponding numerical value. For each number we must put a point, so we can count the frequency of different values.

Based on the above, we can infer that the line plots of points 6 and 7 would look like this:

The bedroom has a surface space of 17.4225 m² and the closet has a surface area of 2.5875 m².

In mathematics, the area is a measure of the amount of two-dimensional space taken up by a shape. It is a scalar quantity, meaning it has only magnitude and no direction. The unit of measurement used for area depends on the units used for the length of the sides of the shape. Common units used to measure area include square centimeters, square meters, square inches, and square feet. The formula for finding the area of a shape depends on the specific type of shape. For example, the area of a rectangle is given by the formula A = lw, where l is the length and w is the width of the rectangle. The area of a triangle is given by the formula A = (1/2)*bh, where b is the base and h is the height of the triangle.

Here,

area of bedroom=l*w

l=5.05 m

w=3.45 m

area of bedroom=5.05*3.45

=17.4225 m²

area of closet=l*w

l=0.75 m

w=3.45 m

area=0.75*3.45

=2.5875 m²

The area of the bedroom is 17.4225 m² and that of closet is 2.5875 m².

The population of the bees when it was first measured was 500 bees

The bees are  growing by the same factor each week. The answer is yes

At the fist time the bees where measured, we have to measure from the origin of the graph.

The first point on the graph is at the population of 500

2. To get if the growth is by the same factor, we have to observe how the growth is taking place weekly

In the first week, it grew from 500 to 1000

1000 / 500 = 2

In the second week, the growth is from 2000 to 1000

2000 / 1000 = 2

In the third week. the growth is from 2000 to 4000

4000 / 2000 = 2

Hence there is a growth constant of 2 across the weeks

The equation of the line that has a slope of -4 and passes through the point (4, -1) is y = -4x + 15.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of a line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given:
An equation,

y = x/4 - 2.

The slope of the line that is perpendicular to the line y = x/4 - 2 is,

From the given information, by doing unit conversion 20 ounces is equal to approximately 1.25 pounds.

Unit conversion is the process of converting a given quantity from one unit of measurement to another. It involves using conversion factors or conversion equations to change the numerical value of the quantity while keeping the physical quantity constant. Common units of measurement include length, mass, volume, time, temperature, and many others.

To convert ounces to pounds, you can use the following conversion formula:

1 lb = 16 oz

So, to convert 20 ounces to pounds, you can divide 20 by 16:

20 oz ÷ 16 oz/lb = 1.25 lb (rounded to two decimal places)

The second and fourth graphs represent linear functions.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

To determine which of the given graphs represents a linear function, we need to check whether the graph is a straight line.

The first graph passes through the points (-3, 0), (-1, -4), and (1, 0). We can plot these points and see that they do not lie in a straight line. Therefore, the first graph does not represent a linear function.

The second graph passes through the points (-4, 0), (0, -4), (4, 0), and (0, 4). We can plot these points and see that they do lie on a straight line. Therefore, the second graph represents a linear function.

The third graph passes through the points (-4, -2), (-4, -1), and (-4, 0). We can plot these points and see that they lie on a vertical line. Therefore, the third graph does not represent a linear function.

The fourth graph passes through the points (-4, 0), (-2, -1), and (0, -2). We can plot these points and see that they do lie on a straight line. Therefore, the fourth graph represents a linear function.

A linear function has a constant rate of change, which means that the change in the value of y is proportional to the change in the value of x. This means that if we plot the points (x,y) for a linear function, they will fall on a straight line.

To determine which of the tables represents a linear function, we can calculate the rate of change between the points. If the rate of change is the same for all pairs of points, then the table represents a linear function.

For the first table:

Rate of change between (−2,4) and (−1,1) = (1−4)/(−1−(−2)) = −3

Rate of change between (−1,1) and (0,−2) = (−2−1)/(0−(−1)) = −3

Rate of change between (0,−2) and (1,−5) = (−5−(−2))/(1−0) = −3

Rate of change between (1,−5) and (2,−8) = (−8−(−5))/(2−1) = −3

Since the rate of change is constant (equal to −3) for all pairs of points, the first table represents a linear function.

For the second table:

Rate of change between (−2,4) and (−1,1) = (1−4)/(−1−(−2)) = −3

Rate of change between (−1,1) and (0,0) = (0−1)/(0−(−1)) = 1

Rate of change between (0,0) and (1,1) = (1−0)/(1−0) = 1

Rate of change between (1,1) and (2,4) = (4−1)/(2−1) = 3

Since the rate of change is not constant (it changes from −3 to 1 to 3), the second table does not represent a linear function.

For the third table:

Rate of change between (2,−2) and (2,−1) is undefined since x does not change.

Rate of change between (2,−1) and (0,0) = (0−(−1))/(0−2) = 0.5

Rate of change between (0,0) and (2,2) = (2−0)/(2−0) = 1

Rate of change between (2,2) and (2,−2) is undefined since x does not change.

Since the rate of change is not constant (it changes from undefined to 0.5 to 1 to undefined), the third table does not represent a linear function.

For the fourth table:

Rate of change between (0,−2) and (1,1) = (1−(−2))/(1−0) = 3

Rate of change between (1,1) and (2,0) = (0−1)/(2−1) = −1

Rate of change between (2,0) and (3,1) = (1−0)/(3−2) = 1

Rate of change between (3,1) and (4,−2) = (−2−1)/(4−3) = −3

Since the rate of change is not constant (it changes from 3 to −1 to 1 to −3), the fourth table does not represent a linear function.

Therefore, the only table that represents a linear function is the first one.

0900 military time is 9:00 AM in the 24-hour time format used by the military, also known as the 24-hour clock.

The 24-hour clock is a timekeeping system that uses a continuous count of 24 hours, instead of two sets of 12 hours for AM and PM. In this system, each hour of the day is numbered from 0 to 23, and is referred to as "military time" or "24-hour time". So, 0900 military time is equivalent to 9:00 AM, with the "0" indicating the first hour of the day.

The probability of obtaining 3 heads in four flips of a fair coin is 1/4.

The probability of obtaining 3 heads in four flips of a fair coin can be calculated using the binomial probability formula. The formula is:

[tex]P(X = k) = (n choose k) * p^k * (1 - p)^{(n - k)}[/tex]

where P(X = k) is the probability of obtaining k successes (in this case, 3 heads), and n is the total number of trials (in this case, 4 flips).

p is the probability of success on a single trial (in this case, 0.5 since the coin is fair), and (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.

Plugging in the values, we get:

[tex]P(X = 3) = (4 choose 3) * 0.5^3 * (1 - 0.5)^{(4 - 3)}[/tex]

= 4 * 0.125 * 0.5

The numerical values of x and y are 14 and 54 respectively.

The sum of angles on a straight line is equal to 180 degrees.

From the diagram, angle (9x + 2)° and angle (5x - 18)° are on a straight line,

Since the sum of angles on a straight line is equal to 180 degrees.

(9x + 2)° + (5x - 18)° = 180°

Solve for x

9x + 2 + 5x - 18 = 180

14x - 16 = 180

14x = 180 + 16

14x = 196

x = 196/14

x = 14

Now, angle (9x + 2)° and angle (2y + 20)° are corresponding angles.

Since corresponding angles are congruent.

(9x + 2)° = (2y + 20)°

Plug in x = 14 and solve for y

9( 14 ) + 2 = 2y + 20

126 + 2 = 2y + 20

128 = 2y + 20

128 - 20 = 2y
