Answer:
shaded area ≈ 69.53 cm²
Step-by-step explanation:
the shaded area (A) is calculated as
A = area of square - area of circle
area of square = 18² = 324
area of circle = πr² ( r is the radius )
the diameter of the circle = 18 , so r = 18 ÷ 2 = 9
area of circle = π × 9² = 81π
then
A = 324 - 81π ≈ 69.53 cm² ( to 2 decimal places )

The probability that event A or B takes place is 17/19
Probability of an eventProbability is defined as the ratio of the required to the total possible outcomes of an event.
The probability of event A or B taking place can be defined as ;
P(A or B) = P(A) + P(B)
P(A) = 10/19
P(B) = 7/19
Hence,
P(A) + P(B) = 10/19 + 7/19
L.C.M of 19 and 19 = 1
P(A) + P(B) = (10 + 7)/19
P(A) + P(B) = 17/19
Therefore, the probability that event A or B takes place is 17/19

y = x² + 6x - 12
a =______
b = _____
c=______
h=______
k =_____
y-intercept=______
x-intercepts =______
and_____
Answer:
See below for answers and explanations
Step-by-step explanation:
a, b, and c are the coefficients of the quadratic, so a=1, b=6, and c=-12
(h,k) is the vertex of the parabola, so we must convert it to vertex form by completing the square:
[tex]y=x^2+6x-12\\y+21=x^2+6x-12+21\\y+21=x^2+6x+9\\y+21=(x+3)^2\\y=(x+3)^2-21[/tex]
Therefore, the vertex is (3,-21), which means h=-3 and k=-21.
The y-intercept is when x=0, or when the function passes through the x-axis:
[tex]y=x^2+6x-12\\y=0^2+6(0)-12\\y=-12[/tex]
Therefore, the y-intercept is -12 (also written as (0,-12) as an ordered pair).
The x-intercept is when y=0, or when the function passes through the y-axis:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-6\pm\sqrt{6^2-4(1)(-12)}}{2(1)}\\\\x=\frac{-6\pm\sqrt{36+48}}{2}\\\\x=\frac{-6\pm\sqrt{94}}{2}[/tex]
Therefore, the x-intercepts are (-6+√94)/2 and (-6-√94)/2.

Out of a pool of 26 men and 29 women what is the probability that 6 men and 6 women will be selected?
Let's evaluate the probability based on the given information.
The number of ways to choose 6 men from 26 can be calculated as:
C(26, 6) = 26! / (6! * (26-6)!) = 26! / (6! * 20!) = 230,230.
The number of ways to choose 6 women from 29 can be calculated as:
C(29, 6) = 29! / (6! * (29-6)!) = 29! / (6! * 23!) = 177,100.
The total number of possible outcomes is the combination of selecting 6 men and 6 women from the given pool of 26 men and 29 women:
Total outcomes = C(26, 6) * C(29, 6) = 230,230 * 177,100 = 40,795,315,300.
Therefore, the probability of selecting exactly 6 men and 6 women from the given pool is:
Probability = 1 / Total outcomes = 1 / 40,795,315,300 ≈ 2.45 x 10^-11.
Hence, the probability is approximately 2.45 x 10^-11.
A camera has a listed price $859.95 of before tax. If the sales tax rate is 9.5% , find the total cost of the camera with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
$941.65
Step-by-step explanation:
Salex tax:We have to find the sales tax of the camera.
tax rate = 9.5%
listed price = $859.95
[tex]\sf Sales \ tax = tax \ rate * listed \ price[/tex]
= 9.5 % * 859.95
= 0.095 * 859.95
= $81.70
To find the total cost, add the sales tax to the listed price.
Total cost = 859.95 + 81.70
= $941.65

Out of a pool of 26 men and 29 women what is the probability of 12 women jurors being chosen?
The probability of 12 women jurors being chosen is approximately 0.000342 or 0.0342%.
To calculate the probability of selecting 12 women jurors out of a pool of 26 men and 29 women, we need to consider the total number of possible combinations and the specific combination of interest.
The total number of ways to choose 12 individuals from a pool of 55 (26 men + 29 women) is given by the combination formula:
C(55, 12) = 55! / (12! * (55-12)!) = 22579284062370.
The number of ways to choose 12 women from a pool of 29 is given by the combination formula:
C(29, 12) = 29! / (12! * (29-12)!) = 7726160.
Therefore, the probability of selecting 12 women jurors is the ratio of the number of ways to choose 12 women to the total number of possible combinations:
P(12 women jurors) = C(29, 12) / C(55, 12) ≈ 7726160 / 22579284062370 ≈ 0.000342.

Based on the supply graph and the demand graph shown above, what is the price at the point of equilibrium?
Hint: Think about the point where they both meet. For example, if you were to place the graphs on top of each other, what would be the point of intersection?
Type the correct number below without the dollar sign.
Based on the supply graph and demand graph shown above, the price at the point of equilibrium is $ 30.
Demand refers to quantity of a commodity that the consumers are willing to, able to purchase at a given price during a given period of time. Supply refers to quantity of a commodity that the producers are willing to, able to offer for sale at a given price during a given period of time.
Demand curve slopes downward due to inverse relationship between price and quantity demanded whereas supply curve slopes upward due to direct relationship between quantity supplied and price. When both demand and supply curve intersect with each other balance is achieved. Intersection point between demand and supply curve is known as equilibrium.
At this point when prices are equal is known as equilibrium price and when quantiy demanded or supplied are equal it is known as equilibrium quantity. When we combine the given graph. Equilibrium is achieved at a point when price is equal to $ 30 and quantity is equal to 20 units.

The final result of the integral is:
∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,
where Li(x) is the logarithmic integral function and C is the constant of integration.
We have,
To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.
Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:
∫ (log(1 + (u-1)²) / u²) du.
Expanding the numerator, we have:
∫ (log(1 + u² - 2u + 1) / u²) du
= ∫ (log(u² - 2u + 2) / u²) du.
Now, let's split the logarithm using the properties of logarithms:
∫ (log(u² - 2u + 2) - log(u²)) / u² du
= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.
We can simplify the second integral:
∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.
Using the power rule for integration, we can integrate both terms:
∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.
Now, let's focus on the second integral:
∫ (log(u) / u³) du.
This integral does not have a simple closed-form solution in terms of elementary functions.
It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).
Therefore,
The final result of the integral is:
∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

Write the equation for a parabola that opens down, translated to the right 3, and translated down 2
Answer:
The equation for a parabola that opens down, translated to the right 3, and translated down 2 can be written in the standard form as:
y = a(x - h)^2 + k
where (h,k) represents the vertex of the parabola. Since the parabola opens down, the value of 'a' must be negative. The vertex is translated to the right 3 and down 2, so we have:
h = -3 and k = -2
Substituting these values in the standard form equation, we get:
y = a(x + 3)^2 - 2
This is the equation for a parabola that opens down, translated to the right 3, and translated down 2.
a bread making machine pours out 50 kg of mixture in 8 minutes in 8 minutes.at what rate is the mixture being poured?
To calculate the rate at which the mixture is being poured, we divide the amount of mixture poured (in kilograms) by the time it takes (in minutes):
Rate = Amount of mixture / TimeIn this case, the amount of mixture poured is 50 kg, and the time taken is 8 minutes. Plugging these values into the formula, we have:
Rate = 50 kg / 8 minDividing 50 kg by 8 min gives us:
Rate = 6.25 kg/minTherefore, the mixture is being poured at a rate of 6.25 kilograms per minute.
If you are trying to determine which company has higher salaries, which measure of center should you use?

mean median mode
To determine which company has higher salaries, you can use the mean, median, or mode as measures of center. Let's calculate each of these measures for the given data:
Company A salaries: 45,000, 55,000, 53,000, 51,000, 49,000, and 42,000.
Mean (Average):
To calculate the mean, sum up all the salaries and divide by the total number of salaries.
Mean of Company A salaries = (45,000 + 55,000 + 53,000 + 51,000 + 49,000 + 42,000) / 6 = 295,000 / 6 = 49,167
Median:
To find the median, you arrange the salaries in ascending order and find the middle value. If there is an even number of values, you take the average of the two middle values.
Arranging the Company A salaries in ascending order: 42,000, 45,000, 49,000, 51,000, 53,000, 55,000
Median of Company A salaries = (49,000 + 51,000) / 2 = 50,000
Mode:
The mode represents the value(s) that appear most frequently in the dataset.
In Company A salaries, all the values occur only once, so there is no mode.
Now let's calculate the same measures for Company B salaries:
Company B salaries: 54,000, 39,000, 51,000, 52,000, 44,000, and 48,000.
Mean of Company B salaries = (54,000 + 39,000 + 51,000 + 52,000 + 44,000 + 48,000) / 6 = 288,000 / 6 = 48,000
Arranging the Company B salaries in ascending order: 39,000, 44,000, 48,000, 51,000, 52,000, 54,000
Median of Company B salaries = (48,000 + 51,000) / 2 = 49,500
Mode of Company B salaries = There are no repeating values, so there is no mode.
To summarize:
- Mean of Company A salaries: $49,167
- Median of Company A salaries: $50,000
- Mode of Company A salaries: No mode
- Mean of Company B salaries: $48,000
- Median of Company B salaries: $49,500
- Mode of Company B salaries: No mode
Based on these measures of center, we can see that the mean and median salaries of Company A are slightly higher than those of Company B. However, since there is no mode in either dataset, we cannot consider the mode as a determining factor in this case.

OC. g(x) is a reflection of f(x) over the y-axis.
D. g(x) is a reflection of f(x) over the x-axis.
The correct statement regarding the reflection rules in this problem is given as follows:
D. g(x) is a reflection of f(x) over the x-axis.
How to define the reflection?The functions f(x) and g(x) in the context of this problem are defined as follows:
f(x) = 2x².g(x) = -2x².The entire function was multiplied by -1, meaning that the signal of the function was exchanged, hence the function was reflected over the x-axis.
As the function was reflected over the x-axis, the correct option in the context of the problem is given by option D.
