A real estate agent received a 5.5% commission on the sale of a home. If her
commission was $14,960, how much did the home sell for?
The amount of the sale of the home is $2090181.82
How to determine how much the home sells for?From the question, we have the following parameters that can be used in our computation:
Commission = 5.5% on the sale of a home
Also, we have
Commission = 114960
using the above as a guide, we have the following:
5.5% on the sale of a home = 114960
So, we have
5.5% * sale of a home = 114960
Divide both sides by 5.5%
sale of a home = 114960/(5.5%)
Evaluate
sale of a home = 2090181.82
Hence, the sale of the home is $2090181.82

Public health officials believe that 91​% of children have been vaccinated against measles. A random survey of medical records at many schools across the country found​ that, among more than​ 13,000 children, only 88.1​% had been vaccinated. A statistician would reject the​ 98% hypothesis with a​ P-value of P= 0.0001.
Required:
a. Explain what the P-value means in this context.
b. The result is statistically significant, but is it important?
Answer:
a) The p value is a probability always between 0 and 1 and represent the evidence in favor of the alternative hypothesis if it's a low value then we have enough evidence to reject the null hypothesis otherwise we FAIl to reject the null hypothesis
b) For this case the result is important because the parameter established by the Public Healt is incorrect ,we obtain a significant result so then there is enough evidence to conclude that the true proportion of children that have been vaccinated against measles is lower than 91%
Step-by-step explanation:
For this case the system of hypothesis are:
Null hypothesis:\(p=0.91\)
Alternative hypothesis:\(p < 0.91\)
When we conduct a proportion test we need to use the z statisitc, and the is given by:
\(z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}\) (1)
For this case after conduct the hypothesis we have the following p value obtained:
\( p_v = 0.0001\)
Part a
The p value is a probability always between 0 and 1 and represent the evidence in favor of the alternative hypothesis if it's a low value then we have enough evidence to reject the null hypothesis otherwise we FAIl to reject the null hypothesis

A right circular cone has a base radius of $6,$ and a lateral surface area of $12 \sqrt{34} \cdot \pi.$ find the volume of the cone.
The volume of the cone is 36π * 2√(34).
The formula for the lateral surface area of a right circular cone is:
A = π * r * l
where A is the lateral surface area, π is the constant pi, r is the radius of the base, and l is the slant height of the cone.
Given that the lateral surface area of the cone is 12√(34) * π, we can write:
\(12\sqrt{(34)} * \Pi = \Pi * r * l\)
Dividing both sides by π and r, we can find the slant height:
l = 12√(34) / r
= 12√(34) / 6
= 2√(34) units
The volume of a right circular cone can be found using the formula:
V = (1/3) * π * r^2 * h
where V is the volume,
π is the constant pi,
r is the radius of the base, and
h is the height of the cone.
Since the cone is a right circular cone, the slant height is also the height of the cone,
So we can substitute l for h:
V = (1/3) * π * r^2 * l
= (1/3) * π * 6^2 * 2√(34)
= 36π * 2√(34)

Rectangle A is three times larger than Rectangle B. Rectangle B is 4
centimeters long and 6 centimeters wide. Given that Rectangle A and
Rectangle B are similar, what is the area of Rectangle A?
OA. 216 cm²
OB. 60 cm²
OC. 540 cm²
OD. 72 cm²
Step-by-step explanation:
hmmm, what is meant by "3 times larger" ?
the area of the rectangle is 3 times larger ? that would be the normal understanding.
or the side lengths are 3 times larger ? which would make the area 9 (3×3) times larger.
for the first possibility :
area of B is 4 cm × 6 cm = 24 cm²
A is 3 times larger would mean
area of A = 3×24 = 72 cm²
for the second possibility :
A is 3 times larger would mean it side lengths would be
3×4 = 12 cm
and
3×6 = 18 cm
area of A = 12×18 = 216 cm²
or short
area of A is 9 times area of B = 9×24 = 216 cm²
as both (72 and 216) are in the list of answer possibilities, I would say that the extra info (that both rectangular are similar) indicates that the question was aiming for the second possibility.
so, A, 216 cm² is then the right answer.
Equation A is equal to (C + D) x (C + D). Equation B is equal to 2 x (C + D). If C and D were numbers that were greater than zero, which equation would give you a bigger value ? Equation A or Equation B ? Give an example for C and D that supports your answer. PLEASE HELP TIMED EXAM!!!!!
According to the question an example of C = 3 and D = 2 supports the answer that Equation A gives a bigger value than Equation B.
What is equation?Two equations are considered to be comparable when their roots and solutions line up. To create an equivalent equation, the identical quantity, symbol, or expression has to be added to or removed from both of the equation's two sides. We can also create a similar equation by dividing or multiplying each component of an equation with a nonzero value.
given,
To determine which equation would give a bigger value, we can compare the expressions obtained by expanding Equation A and simplifying Equation B.
Expanding Equation A, we get:
A = (C + D) x (C + D) = C² + 2CD + D²
Simplifying Equation B, we get:
B = 2 x (C + D) = 2C + 2D
To compare the values of A and B, let's choose some values for C and D that are greater than zero. Let's choose C = 3 and D = 2.
Plugging these values into Equation A, we get:
A = 3² + 2(3)(2) + 2² = 9 + 12 + 4 = 25
Plugging these values into Equation B, we get:
B = 2(3 + 2) = 2(5) = 10
Since A is greater than B for the values of C = 3 and D = 2, we can conclude that Equation A gives a bigger value than Equation B for positive values of C and D.
Therefore, an example of C = 3 and D = 2 supports the answer that Equation A gives a bigger value than Equation B.

The area of the composite figure is equal to 75.5 square meters
How to calculate for the area of the figureThe composite figure can be observed to be made up of a big rectangle, a smaller rectangle, a triangle and a smaller triangle. We calculate for the area of the four shapes and sum the results to get the total area of the composite figure as follows:
area of the big rectangle = 6 m × 4 m = 24 m²
area of the smaller rectangle = 7 m × 2 m = 14 m²
area of the big triangle = 1/2 × 10 m × 6 m = 30 m²
area of the smaller triangle = 1/2 × 5 m × 3 m = 7.5 m²
total area of the composite figure = 24 m² + 14 m² + 30 m² + 7.5 m²
total area of the composite figure = 75.5 m²

Find the polar coordinates of rectangular coordinates (-√2,1). Limit θ to the interval [0,2pi) and round 2 dceimal places if needed
The point (-√2,1) can also be represented as (√3, 5.18) in polar coordinates.
To find the polar coordinates of the rectangular coordinates (-√2,1), we can use the following formulas:
r = √(x² + y²)
θ = tan^⁻1(y/x)
Plugging in the given values of (-√2,1), we get:
r = √((-√2)² + 1²) = √(2 + 1) = √3
θ = tan^⁻1(1/(-√2)) ≈ 2.0344 radians
Note that since the point (-√2,1) is in the second quadrant, we need to add π to the value of θ obtained from the inverse tangent in order to obtain an angle in the interval [0,2π). Thus, we have:
θ ≈ 2.0344 + π ≈ 5.1779 radians
Rounding to 2 decimal places as needed, we get the polar coordinates of (-√2,1) as (r,θ) ≈ (√3, 5.18).

The percentage of our new facility's seating is full will be 76%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The percentage is given as,
Percentage (P) = [Initial value - Final value] / Initial value x 100
Our new training room can seat 150 employees.
If 6 tables consisting of 6 chairs are now taken.
Then the number of occupied seats by tables will be
⇒ 6 x 6
⇒ 36
Then the percentage of our new facility's seating is full will be
P = [(150 - 36) / 150] x 100
P = (114/150) x 100
P = 0.76 x 100
P = 76%

Zack is on his school's color guard and is practicing throwing and catching his flag. He throws the flag into the air from a height of 5 feet at a velocity of 30 feet per second. After the flag starts to come back down, he catches it 7 feet above the ground.
To the nearest tenth of a second, how long is the flag in the air before Zack catches it?
Hint: Use the formula h=16t2+vt+s.
The Nearest tenth of a second, the flag is in the air for approximately 0.1 seconds before Zack catches it.
To determine the time the flag is in the air before Zack catches it, we can use the kinematic equation for vertical motion:
h = 16t^2 + vt + s
Where:
h is the height of the flag,
t is the time in seconds,
v is the initial vertical velocity of the flag,
s is the initial height of the flag.
In this case, the flag is thrown into the air from a height of 5 feet (s = 5) with an initial vertical velocity of 30 feet per second (v = 30). Zack catches it at a height of 7 feet (h = 7).
We can rewrite the equation as:
7 = 16t^2 + 30t + 5
To find the time (t) when the flag is at a height of 7 feet, we can rearrange the equation and solve for t. However, since this is a quadratic equation, we can also use the quadratic formula.
The quadratic equation in this case is:
16t^2 + 30t + 5 - 7 = 0
16t^2 + 30t - 2 = 0
Now, we can use the quadratic formula:
t = (-b ± √(b^2 - 4ac)) / (2a)
Applying the values from the quadratic equation, we have:
t = (-30 ± √(30^2 - 4 * 16 * (-2))) / (2 * 16)
Simplifying further:
t = (-30 ± √(900 + 128)) / 32
t = (-30 ± √1028) / 32
Using a calculator, we find two solutions:
t ≈ -1.08 seconds or t ≈ 0.06 seconds
Since time cannot be negative in this context, we discard the negative solution.
Therefore, to the nearest tenth of a second, the flag is in the air for approximately 0.1 seconds before Zack catches it.
