Therefore, the area of rectangular house is 138.684 [tex]m^{2}[/tex].
Specify the area.The size of a region on a planar or curved surface can be expressed mathematically using the idea of area. The term "surface area" refers to the area of an open surface or the perimeter of a three-dimensional object, whereas the term "plane area" refers to the area of a shape or planar lamina.
Here,
Given :
the length of the rectangular house =15.24 m
the width of the rectangular house = 9.1 m
thus, we find the area of rectangular house
Using formula,
=> Area= length * width
=> Area = 15.24 * 9.1
=> Area = 138.684 [tex]m^{2}[/tex]

in triangle abc, lines ad and bd are the angle bisectors of angle a and b and line de is parallel to line ab find the length of line de if perimeter of abde is 30 cm and ab is 12 cm
If the circumference of ABDE is 30 cm, then the length of the line DE is 6 cm.
The answer to the query is
ABDE's perimeter is 30 cm.
AB length is 12 cm.
Let DE ne length be "x"
Since DE and AB are parallel, the alternate interior angles theorem states that
∠ABE = ∠DEB and ∠BAD = ∠ADE.
Since AD is the angle that bisects ∠A,
∠DAB = ∠EAD
BE is the angle bisector of B, therefore
∠EBD = ∠ABE.
∠EAD = ∠ADE and ∠EBD = ∠BED as a result.
If AE = ED and ED = DB, the triangles ADE and EDB are therefore isosceles. AE = DE = DB = x, then.
Given that ABDE's perimeter is 30 cm,
therefore 12 + 3x = 30,
By finding the x,
=> 3x = 30 -12
=> 3x = 18
=> x = 6 cm.
Consequently, DE has a length of 6 cm.

A stock price will rise if:
Supply of stock is greater than demand
The price-earnings ratio is 10 or greater
Stock yield is greater than 8%
Demand for stock is greater than supply
None of these
A stock price will rise if demand for stock is greater than supply. So, the correct answer is option (d).
What is Stock price ?The stock price or share price is the amount of money it costs to buy shares in a company. Stock prices are not fixed and fluctuate based on market conditions. It is likely to go up if the company is viewed as good, and it is likely to go down if the company is not performing as expected. If there are more people who want to buy a demand than sell (supply ) it, the stock price will go up. Conversely, if more people want to sell than buy stocks, there will be more supply than demand and prices will fall. Understanding supply and demand is easy.

In each case below find an equation for the line with the given information about the linear equation and
give the slope of each line.
a) Vertical line through point (2, -65)
b) Horizontal line through point (-2, 4)
a) The equation of a vertical line is x = k, where k is the x-coordinate of the point where the line intersects the y-axis. In this case, the point where the line intersects the y-axis is (2, -65), so the equation of the line is x = 2. The slope of a vertical line is undefined, since it has no slope.
b) The equation of a horizontal line is y = k, where k is the y-coordinate of the point where the line intersects the x-axis. In this case, the point where the line intersects the x-axis is (-2, 4), so the equation of the line is y = 4. The slope of a horizontal line is 0, since it has no slope.

A restaurant serves pancakes that are made from a powdered pancake mix. There is a proportional relationship between the number of scoops of powdered pancake mix and the amount of water needed to make them. For every 4 scoops of mix, one half quart of water is needed, and for every 12 scoops of mix, one and one half quarts of water are needed.
Part A: Find the constant of proportionality. Show every step of your work. (4 points)
Part B: Write an equation that represents the relationship. Show every step of your work. (2 points)
Part C: Describe how you would graph the relationship. Use complete sentences. (4 points)
Part D: How many quarts of water are needed for 20 scoops of pancake mix? (2 points)
Answer:
See below
Step-by-step explanation:
If I make x the scope of mix and y the quarts of water, my equation would be y = .125x
I can find the constant of Proportionally by y/x
Using points (4,.5) and (12,1.5)
(.5/4) = 0.125
(1.5/12) = 0.125
The equation would then be:
y = 0.125x
C see the graph provided from Desmos (a free graphing calculator). as x Increases by 1, y increases by 0.125
y = 0.125x
y =.0125(20)
y = 2.5
For 20 scoops, I would need 2.5 quarts of water.
You can also see from the graph as 8 scoops, I would need 1 quart of water.

-1/6x-5=2/3x
A. x= - 6.
B. x = -5.
C. x = 3.
D. x = 6.
Answer:
A. x = -6
Step-by-step explanation:
-1/6x - 5 = 2/3x
add 1/6x to both sides:
-1/6x - 5 + 1/6x = 2/3x + 1/6x
-5 = 2/3x + 1/6x
common denominator on right side:
-5 = 4/6x + 1/6x
combine right side:
-5 = 5/6x

Determine the nth term formula for the number of square tiles in the nth figure.
Answer:
the nth term is 2n
Step-by-step explanation:
notice how for each number of tiles, 2, 4, 6, 8, 10, they are all multiples of 2, so like ok 2 is definitely in the term, next check how n can fit. Well, since they are multiples, you multiply n by 2, now check to see if you dont need to add any values by the following method:
first number = 2, then 2(1) = 2 if n = 1
second = 4, then (2)(2) = 4 if n = 2
its all the same for the rest. Each new diagram or tile structures represents n, so if n =1, then there are 2 tiles, if n = 4 there are 8 tiles and so on, which explains us why the nth term is 2n
The nth term formula for the number of square tiles in the nth figure is aₙ=2n.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.

B) Interpret the slope and y-intercept , if appropriate.
C) Predict the final grade for a student who misses five class periods and compute the residual. Is the final grade abover or below average for this number of absenses.
D) Draw a least-sqaures regression line on the scatter diagram of the data.
E) Would it be reasonable to to use the least-sqaures regression line to predict the final grade for a student who has missed 15 class periods? why or why not?
We get the following answers:
A) The least square regression line is:
yi = 88.73 - 2.827(xi)
B) The slope is β₁ = -2.827 and The intercept is β₀ = 88.73.
C) e*₆ = -0.6964, final grade is below average grade.
E) It would not be reasonable since no of absence increases the score decreases, it works well for small no of absences but will not work for large number of absences since it may give absurd final grade.
we have Xi = No of absences
Yi = Final grade
The regression model is
Yi = β₀ + β₁Xi + i
β₀ = y - β₁x
we have n = 10, x bar = 4.5 , y bar = 76.01
cov(x,y) = -23.325 and var(x) = 9.1667
therefore, β₀ = 88.73 and β₁ = -2.827
A) Least square regression line is given by:
yi = β₀+ β₁Xi
yi = 88.73 - 2.827(xi)
B) The slope β₁ = -2.827 which means when no of absence is increased by 1 duty then the final grade will decrease by 2.827
The intercept β₀ = 88.73 when there are 0 days absence the average grade is 88.73
C) Predicted graph for student who misses five class periods is
x = 5
y*5 = 88.73 - 2.827(5) = 74.5964
Hence for corresponding residual is:
e*₆ = 73.9 - 74.5964
e*₆ = -0.6964, final grade is below average grade.
D) please see graph
E) when student miss 15 class periods the final grade will be
X = 5
y* = 88.73 - 2.827(15)

33% of millennials rely on blogs before making a purchase and eight out of 10 millennials never buy anything without reading a review first. In a sample size of 75 Millennials, how many people use blogs to make a purchase? In a sample size of 75 Millennials, how many people never buy anything without reading a review first?
Number of people that use blogs to make a purchase are 24.75= 25 and number of people that never buy anything without reading a review first are 60.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, 33% of millennials rely on blogs before making a purchase.
Eight out of 10 millennials never buy anything without reading a review first.
That means,
8 out of 10 is 80%.
In a sample size of 75 millennials:
To find the number of people that never buy anything without reading a review first:
80% of 75
80 x 75 / 100
= 6000/ 100
= 60
To find the number of people that use blogs to make a purchase:
33% of 75
33 x 75 / 100
= 2475/ 100
= 24.75
Therefore, the number of people are 24.75 and 60.

Which ordered pair is NOT a solution to the equation y = 2x?
Point A
Point B
Point C
Point D
The ordered pair that is NOT a solution to the equation y = 2x is (3, 8)
How to determine the ordered pairFrom the question, we have the following parameters that can be used in our computation:
y = 2x
From the graph (see attachment), we have the following points:
A = (1, 2)
B = (2, 4)
C = (3, 8)
D = (5, 10)
The equation y = 2x means that
y is twice of x
In C = (3, 8), 8 is not twice of 3
Hence, the ordered pair that is NOT a solution is C = (3, 8)

Answer:
A, B, C
Step-by-step explanation:
You want to know the correct descriptors of the given graph.
SolutionThe solution to a system of equations is the set of points that satisfy all of the equations at once. On a graph, it will be the set of points where the graphs of the equations intersect.
Here the two lines cross at one point, hence there is one solution.
The point where the lines cross is approximately (3, -0.5). That makes (3, -0.5) a reasonable estimate of the solution of the system.
Two random number generators each generate a number from 1 to 10. What is the probability that both number generators generated the number 5
Hello,
The probability that both number generators generate the number 5 is (1/10) * (1/10) = 1/100 = 0.01 or 1%.
This is because the probability of an event occurring is the product of the probabilities of each event occurring independently. In this case, the probability of the first generator generating the number 5 is 1/10 and the probability of the second generator generating the number 5 is also 1/10, so the probability of both events occurring is (1/10) * (1/10) = 1/100.

a market research firm is studying the effects of price and type of packaging on sales of a particular product. twenty-seven stores with shoppers of similar characteristics will be used in the study. the nine combinations of three price levels and three packaging types are the treatments of interest. total sales of the product over a seven-week period will be recorded. which of the following describes the best design to use for the study?
The most effective study design was "a totally random structure. Randomly choose three stores for each of the nine permutations of the price level as well as packaging type."
Based on information provided by the market research firm
27 shoppers with comparable characteristics in total were included in the study.
There are nine combinations in total.
3 levels are the total amount of price tiers.
Three different package types total.
Total sales time period: 7 weeks
According to the completely randomised design, just one key component needs to be studied in order to determine its impacts.
For each type and level for each combination, we must here employ a completely random design.
Consequently, the appropriate claim is "a totally random structure. Randomly choose three stores for each of the nine permutations of price level but also packaging type."
