The angle subtended by the women voters are 100° more than the angle subtended by the men voters.
The total number of voters are 10080 votersReasons:
The angle subtended by the men on the pie chart = 130°
The number of women = 2800 + The number of men
Therefore;
Angle subtended by the women voters on the pie chart = 360° - 130° = 230°
The difference between the angle representing women and the angle
representing men = 230° - 130° = 100°
Therefore;
100° = 2800
Which by common ratios gives;
\(\dfrac{100^{\circ}}{360^{\circ}} = \dfrac{2800}{Total \ number \ of \ voters }\)
100 × Total number of voters = 2800 × 360
\(The \ total \ number \ of \ voters = \dfrac{2800 \times 360}{100} = 10080\)

Write an iterated integral for triple int f(x,y,z) dV where D is a sphere of radius 4 centered at (0,0,0). Use the order dz dx dy.
This iterated integral can be used to evaluate the triple integral of any function f(x,y,z) over a sphere of radius 4 centered at (0,0,0), using the order dz dx dy.
To write the iterated integral for triple integral of f(x,y,z) over a sphere of radius 4 centered at (0,0,0) using the order dz dx dy, we need to break down the integral into three separate integrals, one for each variable. Here is the iterated integral:
∫ from -4 to 4 ∫ from -sqrt(16 - x^2) to sqrt(16 - x^2) ∫ from -sqrt(16 - x^2 - y^2) to sqrt(16 - x^2 - y^2) f(x,y,z) dz dy dx
In this integral, the outermost integral with respect to x ranges from -4 to 4, since the sphere has a radius of 4. The next integral with respect to y ranges from -sqrt(16 - x^2) to sqrt(16 - x^2), which is the equation of a circle with a radius of sqrt(16 - x^2) in the xy-plane. Finally, the innermost integral with respect to z ranges from -sqrt(16 - x^2 - y^2) to sqrt(16 - x^2 - y^2), which is the equation of a circle with a radius of sqrt(16 - x^2 - y^2) in the xy-plane, and represents the height of the sphere at each point (x,y).

Uw + uq=r
Answer:
u = \(\frac{r}{w+q}\)
Step-by-step explanation:
Given

u(w + q) = r ← divide both sides by (w + q)
u = \(\frac{r}{w+q}\)
The equation uw + uq = r is solved for u will be written as u = r / (w + q).
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

what statistics are robust to outliers
There are several statistics that are robust to outliers: Median, Interquartile range, Winsorized mean and Trimmed mean.
How we find that what statistics are robust to outliers?These statistics are more suitable for datasets that contain outliers as they are less influenced by the extreme values and provide more accurate information about the central tendency and variability of the data.
Median: The median is less sensitive to extreme values in a dataset as it only considers the middle value, regardless of how large or small the other values are.Interquartile range (IQR): IQR is the difference between the third quartile (75th percentile) and the first quartile (25th percentile) of a dataset. It is calculated using the middle 50% of the data and is not influenced by the extreme values.Winsorized mean: The Winsorized mean is calculated by first replacing a fixed percentage (for example, 5%) of the largest and smallest values in a dataset with the nearest remaining value, and then calculating the mean. This method reduces the impact of extreme values on the mean.Trimmed mean: The trimmed mean involves removing a fixed percentage of the smallest and largest values in a dataset and then calculating the mean of the remaining values. This approach is similar to the Winsorized mean and also reduces the influence of extreme values on the mean.Learn more about Statistics are robust to outliers

What is reference angle?An angle's reference angle is the measure of the smallest, positive, acute angle formed by the terminal side of the angle and the horizontal axis.
The positive reference angles have terminal sides that lie in the first quadrant and can be used as models for angles in other quadrants.
The reference angle is acute angle, it must be < 90°.
The terminal side lies in Quadrant II.

the value of tan(θ) is 12/35.The closest answer choice to this value is (A) 0.3243, which is approximately equal to 12/37.
what is approximately ?
"Approximately" means "about" or "roughly." It is used to indicate that a given value or measurement is not exact, but is close enough to be a useful estimate.
In the given question,
Since we know sin(θ) = opposite/hypotenuse, we can use the given value sin(θ) = 12/37 to find the adjacent side of the triangle using the Pythagorean theorem. Let's call the adjacent side x:
sin(θ) = opposite/hypotenuse
sin(θ) = 12/37
opposite = 12, hypotenuse = 37
cos(θ) = adjacent/hypotenuse
cos(θ) = x/37
Using the Pythagorean theorem, we know that:
opposite² + adjacent² = hypotenuse²
12² + x² = 37²
144 + x² = 1369
x² = 1225
x = 35
So, the adjacent side is 35.
Now that we know the opposite and adjacent sides, we can use the tangent function to find the value of tan(θ):
tan(θ) = opposite/adjacent
tan(θ) = 12/35
Therefore, the value of tan(θ) is 12/35.
The closest answer choice to this value is (A) 0.3243, which is approximately equal to 12/37.

A.67
B.149
C.288
D.365
Answer:
149
Step-by-step explanation:
12× 24 = 288
228 - 139 = 149
Answer:
B. 149
Step-by-step explanation:
If the students have already filled 139 balloons with air and are going to use all the bags. They would need to fill 149 more balloons.
The first step would be to find the total number of ballons by calculating 12x24 which will give you 288.
From here you would need to subtract the number of ballons that are already filled with air from the balloons that remain which would be 288-139. This would give you a total of 149 balloons that still need to be inflated.

The amount of the first powder that the pharmacist uses is -100 milligram and the amount of the second powder that the pharmacist uses is 1500mg
Let the amount of the first powder that the pharmacist uses "x" (in milligrams), and the amount of the second powder "y" (also in milligrams).
0.20x + 0.10y = 130 (equation 1)
0.15x + 0.10y = 180 (equation 2)
Subtract equation 2 from 1
0.20x-0.15x=130-180
0.5x=-50
Divide both sides by 0.5
First powder x=-100
Now plug in -100 to find y
0.20(-100)+0.10y=130
-20+0.10y=130

"The definition of good mathematical problem is the mathematics it generates rather than the problem itself"
Andrew Willes
ANSWER:People interpret things differently there have been math problems that were told to be unsolved until someone viewed it differently and solved it. If you never try it, you will never solve it. Some problems seem simple but you try them for a year, ten years, a hundred years and it turns out they are extremely hard to solve. Simple but challanging math problems. The Good Math problems are those that look simple but are hard to solve. The problem itself looks simple But the math it generates is hard and complex to solve.
It is saying that to have a good mathematical problem depends on what that problem is (generates)
Some mathematical problems will be easier or harder than others.
But It is saying that the definition of a good problem is because it's mathematical not what the quesiton is.
a geometric sequence has only positive terms. the third term is 100 and the eighth term is 3.125. find the common ratio. [answer format: 0.0]
The common ratio of the sequence is 0.5.
The common ratio of a geometric sequence can be found by dividing any term by its previous term. Let's call the first term "a" and the common ratio "r". Then we have:
third term = a * r^2 = 100
eighth term = a * r^7 = 3.125
We can divide the equation for the eighth term by the equation for the third term to eliminate "a":
\((a * r^7) / (a * r^2) = 3.125 / 100\)
\(r^5 = 0.03125\)
r = 0.5
Therefore, the common ratio of the sequence is 0.5.
We are given two terms of a geometric sequence and are asked to find the common ratio. We can use the formula for the nth term of a geometric sequence to write two equations involving the first term "a" and the common ratio "r". By dividing the two equations, we can eliminate "a" and solve for "r". In this case, we get a fifth degree equation for "r", which we can solve using a calculator or by recognizing that 0.03125 is equal to 1/32, and therefore r is equal to the fifth root of 1/32, which simplifies to 0.5.
