Find the value of x. Then find the measure of each angle and write the answers in ascending order.

The required linear model is y = 5800 + 324x.

What is a linear equation?

Equations whose variables have a power of one are called linear equations.

Given, a bakery sells 5800 muffins in 2010

the bakery sells 7420 muffins in 2015

So, the number of muffins sold after 2010 through 2015:

7,420 - 5,800 = 1,620

Then, the sales per year:

1,620 muffins sold since 2010 / 5 years = 324 muffins per year.

Then our linear model will be:

y = 5800 + 324x

Hence, the required linear model is y = 5800 + 324x.

The method used by Horace to select his sample is Systematic Sampling.

A form of probability sampling technique called systematic sampling selects sample members from a broader population using a predetermined, periodic interval in addition to a random beginning point. The population size is divided by the intended sample size to arrive at this range, which is known as the sampling interval.

Horace desires to select every 1000th person to enter the park, starting with the 364th person. So he selects the 364th person, 1364th person, 2364th person, and so on. This is a perfect situation for Systematic Sampling.

The point-slope form of the equation of Street D is; y = 0.8·(x - 5)

The point-slope of the equation of straight line can be expressed mathematically as (y - y₁) = m·(x - x₁)

The coordinates of the point

The x-intercept of the street D = 5

The y-intercept of the street D = -4

The x-intercept is the point the graph of the equation of the street intersects the x-axis.

At the x-intercept, the y-coordinate of the point of the graph is 0, therefore, the coordinate of the x-intercept is (5, 0)

The y-intercept is the point at which the graph of the function intersects the y-axis, therefore, the x-coordinate of the graph at the y-intercept is 0

The y-intercept of the street D is therefore; (0, -4)

The slope, m, of the equation of the street is therefore;

m = (-4 - 0)/(0 - 5) = 4/5 = 0.8

The point-slope form of the equation, using the x-intercept, (5, 0) is therefore;

Answer:

7) d (21)

6) a (102)

Step-by-step explanation:

For the first question, we should start with what we know first:

When angles are complementary then, their angles add up to 90.

So here we have 69 + something = 90.

We find out that the missing angle (angle B) is 21.

For this second question, we know that a straight line has an angle of 180. Here we have a straight line, but only part of the angle in which we only have 78.

Since we know 78 + x = 180

Then we can figure out that x = 102.

The gradient of the line in the given graph is 1/2.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the graph, let us consider two points from where the line is passing.

(-2, 3) and (2, 5).

Gradient is nothing but slope of the line.

Slope of line :

Line slope is a measure of the slope and direction of a line. Finding the slope of a line in the coordinate plane helps predict whether the line is parallel or perpendicular without actually using a compass. The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of the line.

The formula for the slope is

m = (y₂ - y₁)/ (x₂ - x₁)

Where (x₁, y₁) and (x₂, y₂) are the points

We have given a line PQ passing through points (x,z ) and (w,v) then slope of line is

The growth rate of a value (such as GDP, turnover, earnings, etc.) gauges how much it has changed over time (month, quarter, year). The percentage is a fairly universal way to communicate it.

Here, we have

The present size of the population is 7 billion.

Assuming that the population starts growing from the age of "0"

The number of people after 30 years is equal to two times the present population i.e 14 billion

The number of people after 60 years is equal to two times the population after 40 years i.e 28 billion

The population standard deviation of the data is gotten from using the sum of squares and count which gave us 1.5

Standard deviation is used to find the values of a particular data that is dispersed or scattered. Standard deviation can be defined as the deviation of the values or data from an average mean. Lower standard deviation assumes that the values are very close to their average. Meanwhile higher values mean the values are far from the mean value. Note that the value of standard deviation value can never be negative.

The data given is

Given,

Equation of a line;

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

We have to find the equation of a line with 2 points;

The required coordinates of the vertices of △ABC after it has been rotated 90 degrees, reflected across the line y=0, and then translated according to the rule (x+3,y-3) are A''' = [8, 1], B''' = [-3, -6], and C''' = [-5, -4].

To determine the coordinates of the vertices of △ABC after it has been rotated 90 degrees, reflected across the line y=0, and then translated according to the rule (x+3,y-3), we need to apply these transformations to the coordinates of the original vertices in the order given.

First, we rotate the triangle 90 degrees counterclockwise around the origin. This transformation can be represented by the matrix:[cos(90) -sin(90)][sin(90) cos(90)]

Applying this matrix to the coordinates of the vertices of △ABC, we get:A' = [-5, 4]B' = [6, -3]C' = [8, -1]

Next, we reflect the triangle across the line y=0.

This transformation can be represented by the matrix:[-1 0][0 1]

Applying this matrix to the coordinates of the vertices of △ABC', we get:A'' = [5, 4]B'' = [-6, -3]C'' = [-8, -1]

Finally, we translate the triangle according to the rule (x+3,y-3).

This transformation can be represented by the matrix:[1 0][0 1]

Applying this matrix to the coordinates of the vertices of △ABC'', we get:A''' = [8, 1]B''' = [-3, -6]C''' = [-5, -4]

Therefore, the coordinates of the vertices of △ABC after given transformations are A''' = [8, 1], B''' = [-3, -6], and C''' = [-5, -4].
