Point K is located at 3.5 on the number line.

To find point K on the number line, we need to apply the ratio LK to KM, which is 6:3. First, we can simplify this ratio to 2:1.

Next, we will find the total distance between points L and M. The distance LM = 6.5 - (-2.5) = 9 units.

Now, we can divide this distance into 3 equal parts, as per the simplified ratio 2:1. Each part will be 9/3 = 3 units long.

Since LK is 2 parts of the ratio, we will multiply the length of one part (3 units) by 2. LK = 3 * 2 = 6 units.

Finally, we'll find the coordinates of point K by adding the length of LK to the coordinate of point L. So, K = -2.5 + 6 = 3.5.

The probability of rolling a sum from 2 to 12 on 2 dices is 100%

Given the data,

The two dice should be rolled.

Now, there are 36 possibilities that might occur while rolling two normal six-sided dice. The reason for this is that when rolling two dice, the total number of outcomes is the product of the numbers of outcomes for each die, and each die has six potential outcomes (numbers 1 through 6).

The resultant 36 results are as follows:

1-1, 1-2, 1-3, 1-4, 1-5, 1-6

2-1, 2-2, 2-3, 2-4, 2-5, 2-6

3-1, 3-2, 3-3, 3-4, 3-5, 3-6

4-1, 4-2, 4-3, 4-4, 4-5, 4-6

5-1, 5-2, 5-3, 5-4, 5-5, 5-6

6-1, 6-2, 6-3, 6-4, 6-5, 6-6

When using two dice, there are a total of 36 possibilities that might occur.

As a result, the results' total ranges from 2 to 12.

Hence , the probability is 100 %

The equation of line that passes through and is perpendicular toy = (7/5)x + 6 is  [tex]y = -\frac{5}{7}x - \frac{32}{7}[/tex].

The slope-intercept form is expressed as;

y = mx + b

Where m is slope and b is the y-intercept.

Given the equation of the original line:
y = (7/5)x + 6

Using the slope intercept, slope m is 5/2

Slope m = 7/5

Note: the equation of a perpendicular line to y = (7/5)x + 6 must have a slope that is the negative reciprocal of the original slope.

Slope of perpendicular line = -1 / ( 7/5 )

Slope of perpendicular line = -5/7

Plug the slope m = -5/7 and point (2,-6) into point-slope formula and simplify.

1: The required table is described below.

2: The range is (0,36)

3: X-intercepts are (-6,0) and (6,0) and the Y-intercept is (0,36)

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.

We are given that,

y = -x² + 36

The equation of the rainbow is represented by the parabola,

Now, we are required to find a linear equation which cuts the graph of the parabola at two points.

Let us consider the equation joining the points (-6,0) and (0,36), given by .

y = 6x + 36

So, the corresponding table for the linear equation is given by,

x            y = 6x + 36

-6                      0

0                       36

1                        42

6                       72

Now, we will answer the questions corresponding the functions.

1. Domain and Range of the rainbow.

Since, the equation of the rainbow is

y = -x² + 36

So, from the figure, we get that,

Domain is the set of all real numbers.

Range is the set {y | y ≤ 36}

Here, domain represents the points which are used to plot the path of the rainbow and range represents the points which are form the rainbow.

Not all points make sense in the range as the parabola is opening downwards having maximum point as (0,36).

2. X and Y-intercepts of the rainbow.

As, the 'x and y-intercepts are the points where the graph of the function cuts x-axis and y-axis respectively i.e. where y=0 and x=0 receptively'.

We see that from the figure below,

X-intercepts are (-6,0) and (6,0) and the Y-intercept is (0,36)

Here, these intercepts represents the point where the parabola intersects the individual axis.

3. Is the linear function positive or negative.

As the linear function is  represented by the upward flight of the drone.

So, the linear function is a positive function.

y = 6x + 36

4. The solution of the system of equations is the intersection points of their graphs.

So, from the figure, we see that the equations intersect at the points (-6,0) and (0,36).

Thus, the solution represents the position when both the drone and rainbow intersect each other.

The mean score of the test is 7.13.

The median score of the test is 7.

To get mean score, we have to multiply each test score by its corresponding frequency, sum up products and then divide by the total frequency.

Mean score = EF/ n

Mean score = (34 + 41 + 50 + 63 + 73 + 85 + 91 + 106) / (4 + 1 + 0 + 3 + 3 + 5 + 1 + 6)

= (12 + 4 + 0 + 18 + 21 + 40 + 9 + 60) / 23

Applying the inscribed angle theorem, the indicated measures in the circle are: a) m<JIK = 51°; b) m<KJL = 51°.

Recall that the measure of an intercepted arc is equal to twice the measure of an inscribed angle, based on the inscribed angle theorem.

We are given the following:

m(IJ) = 78°

m<IJL = 39°

Therefore, we have:

a. m<JIK = 1/2(m(JK)) [based on the inscribed angle theorem]

m(JK) = 180 - m(IJ)

m(JK) = 180 - 78 = 102°

Answer:

To find the z-score of a data value, we use the following formula:

z = (x - μ) / σ

where z is the z-score, x is the data value, μ is the mean of the distribution, and σ is the standard deviation.

Given a normal distribution with a mean (μ) of 146 and a standard deviation (σ) of 4, and a data value (x) of 153, we can plug these values into the formula:

z = (153 - 146) / 4

z = 7 / 4

z = 1.75

Thus, the z-score of the data value 153 is 1.75.

The correct statements that apply to the given limits are:

Option A: Multiply by (√(x + 2) + 3)/(√(x + 2) + 3)

Option D: "Divide out a common factor of x - 7."

Option E: The limit of the given expression is 1/6.

Option: We generally multiply by the conjugate of the expression to eliminate square roots in simplification. Thus, option A applies.

Option B: Get x - 1 in the numerator:

This statement is not correct. The expression does not involve x - 1 in the numerator.

Option C: Get (x - 7)(√(x + 2) - 3) in the denominator:

This statement is not correct due to the fact that we want to simplify the expression, and not introduce a more complex denominator.

Option D: Divide out a common factor of x - 7:

This statement is correct because by factoring out (x - 7) from both the numerator and denominator, we can cancel out the common factor.

Option E: Calculate the limit as 1/6:

After canceling out the common factor of x - 7, the simplified expression becomes:

lim x -> 7 (√(x + 2) - 3)/(x - 7)

= lim x -> 7 1/(√(x + 2) + 3)

To find the limit, we substitute the value x = 7 into the simplified expression:

Let's start by setting up some equations based on the given information:

Alex's share = 3/4 * (Bill's share + Carl's share)

Bill's share = 2/5 * Carl's share

The sum of all four shares is $168.

We can use the fourth equation to solve for one of the shares in terms of the others:

Alex's share + Bill's share + Carl's share + David's share = $168

Alex's share + Bill's share + Carl's share = $168 - David's share

Substituting the other equations into this expression, we get:

Alex's share + (2/5 * Carl's share) + Carl's share + (1/7 * (Alex's share + (2/5 * Carl's share) + Carl's share)) = $168

Simplifying this equation, we get:

(8/7) * Alex's share + (22/35) * Carl's share = $168

Now we can use the other equations to solve for Carl's share, and then for Bill's share:

From Bill's share = 2/5 * Carl's share, we get Carl's share = (5/2) * Bill's share

From Alex's share = 3/4 * (Bill's share + Carl's share), we get Alex's share = (3/4) * ((7/2) * Bill's share) = (21/8) * Bill's share

Substituting these expressions into the equation we derived earlier, we get:

(8/7) * (21/8) * Bill's share + (22/35) * (5/2) * Bill's share = $168

Step-by-step explanation:

The cost of covering 1 unit² should be $2.477 to be in the budget and the total area to be covered is 3027.22 ft².

Given is a blueprint we need to find area that be covered and then the cost of covering the area,

So, we will find the area by splitting the figure into different shapes,

So the area =

Ar(rectangle) + Ar(semicircle) + Ar(triangle) + Ar(square)

= 9×3 + 3.14×2²/2 + 1/2×3×1 + 3³

= 27 + 6.28 + 1.5 + 27

= 61.78 units²

Since 1 unit = 7 ft

So, 1 unit² = 49 ft²

therefore, 61.78 units² = 61.78 × 49 = 3027.22 ft²

Since our budget is $7500

Costing of covering the area = 3027.22 × x = 7500

x = $2.477

Hence the cost of covering 1 unit² should be $2.477 to be in the budget.
