Natalie is a real estate agent and earns a 3% commission on all homes she sells. She estimates that she will earn $8,250 on the next house she sells. She actually earns $9,210. What was Natalie’s estimate for the selling price of the home? What was the actual selling price of the home?
Using the percentage principle, the estimated and actual sale price of the Home are $275, 000 and $307,000 respectively.
Commission on sale = 3%Estimated commison = $8250
Let Estimated sale price = P
3% × P = 8250
0.03p = 8250
p = 8250 / 3
p = $275000
Actual commission earned = $9210
Let Actual sale price = P
3% × P = 9210
0.03p = 9210
p = 9210 / 3
p = $307,000
Therefore, the estimated and actual sale price are $275,000 and $307,000 respectively.

Step-by-step explanation:
Answer is 2.1 kg and 2.9 kg.
What is an equation?A mathematical definition of an equation is a claim that two expressions are equal and joined by the equals sign "=".
Given that,
Amount of cheese = $8 per kg
Amount of kiwis = $ 3 per kg
Assume
X = quantity of chees
Y = quantity of kiwi
According to the given information,
X + Y = 5 ...(i)
8X + 3Y = (5)4.50 ....(ii)
From (ii) = 3x(i),
5x = 10.5
x = 2.1 kg

Graph the given equation by evaluating integer values of x from -2 to 2 and plotting the resulting points.
y = -2x - 4
Graphs are created from functions and equations.
See attachment for the graph of [tex]\mathbf{y = -2x - 4}[/tex]
The equation is given as:
[tex]\mathbf{y = -2x - 4}[/tex]
When x = -2, we have:
[tex]\mathbf{y = -2(-2) - 4 = 0}[/tex]
When x = -1, we have:
[tex]\mathbf{y = -2(-1) - 4 = -2}[/tex]
When x = 0, we have:
[tex]\mathbf{y = -2(0) - 4 = -4}[/tex]
When x = 1, we have:
[tex]\mathbf{y = -2(1) - 4 = -6}[/tex]
When x = 2, we have:
[tex]\mathbf{y = -2(2) - 4 = -8}[/tex]
So, the points on the graph are:
[tex]\mathbf{(x,y) = (-2,0)(-1,-2)(0,-4)(1,-6)(2,-8)}[/tex]

What is the solution to the system -3×+4y+2z=-3 2×-4y-z=0 y=3x-13
Answer:
x=5, y=2, z=2
Step-by-step explanation:
y=3x-13
-3x+4y+2z = -3x + 4(3x-13) + 2z = 9x+2z-52 = -3
9x + 2z = 49 ... (1)
2x-4y-z = 2x-4(3x-13)-z = -10x-z+52 = 0
10x + z = 52 ... (2)
(2)*2-(1): 11x = 55 x = 5
y = 3x-13 = 15-13 = 2 y=2
z = (49-9x) / 2 = 2 z = 2

Bill is 30 years old. He has just started a new job, and he cycles to work. The
probability of having a serious accident on any given day is 10E−4
(and the days are independent of each other as far as cycling accidents are concerned). He works 250 days per year, and will work for 35 years before retiring to North Hatley–unless a cycling accident catches up with him first.
a) What is the probability that he gets through his career without a serious
cycling accident?
b) Thirty years pass. Bill continues to cycle, and has never had a serious
accident. However, the probability of accident on any given day remains 10E−4
Is the probability that he will get through his entire career without an accident the
same? If so, explain why. If not, calculate it and interpret.
Using the binomial distribution, we have that:
a) 0.4168 = 41.68% probability that he gets through his career without a serious cycling accident.
b) Considering that the probability of an accident on a given day is independent of any other day, now just the last five years are considered, thus, the probability changes and there is a 0.8825 = 88.25% probability that he will get through his entire career without an accident the same.
For each day, there are only two possible outcomes. Either there is an accident, or there is not. The probability of there being an accident on a day is independent of any other day, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
0.0001 probability of an accident on a given day, thus [tex]p = 0.0001[/tex]250 days, for 35 years, thus the number of days is [tex]n = 250(35) = 8750[/tex].Item a:
The probability is P(X = 0), thus:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{8750,0}.(0.0001)^{0}.(0.9999)^{8750} = 0.4168[/tex]
0.4168 = 41.68% probability that he gets through his career without a serious cycling accident.
Item b:
The probability changes, as we consider now just five years.The number of days is now [tex]n = 250(5) = 1250[/tex].Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{8750,0}.(0.0001)^{0}.(0.9999)^{1250} = 0.8825[/tex]
Considering that the probability of an accident on a given day is independent of any other day, now just the last five years are considered, thus, the probability changes and there is a 0.8825 = 88.25% probability that he will get through his entire career without an accident the same.

Hello,
Correct Answer is 12/3
Step-by-step explanation:-For angle theta, perpendicular side is AB=12 and hypotenuse side is BC=13.
The sine of angle is equal to the ratio of perpendicular side to the hypotenuse side. So, sine of angle theta is:-
[tex]sin \: θ = \frac{12}{3} [/tex]
So, sine ratio angle is 12/3.

What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
Expression: 11(d-c)+3(c+d)
Now, put the values of c= 6 and d= 9 we get
11(d-c)+3(c+d)

b. The measure of the missing angle is
nothing. (Simplify your answer.)
Answer:
A. 60 degrees
B. 60 degrees
Step-by-step explanation:
(a)
60 degrees +60 degrees + missing angle = 180 degrees
(angle sum property of triangle)
missing angle = 180 - 120 = 60 degrees
(b)
90 degrees + 30 degrees =120 degrees +missing angle = 180 degrees
missing angle = 60 degrees
