The statement third, “This is voluntary response bias. The result overestimates true support for firing the coach” is correct.
What is a survey?A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.
We have:
A local baseball team is struggling this season, and many fans of the team believe it may be time to replace the head coach.
Number of votes V(n) = 2367
After the value of V(n) 79% of those who responded felt the coach should be fired.
Based on the data given, we can say this is referred to as voluntary response bias. The outcome exaggerates the level of support for firing the coach.
Thus, the statement third “This is voluntary response bias. The result overestimates true support for firing the coach” is correct.

a circular flower bed is 20 meters in diameter and has a circular sidewalk around it that is 3 meters wide . find the area of the sidewalk in square meters . use 3.14 for pie. and round to the nearest whole number
Answer:
Step-by-step explanation:
this is two circles, one inside the other, circles have an area of pi*[tex]r^{2}[/tex] the flower bed is 20 meters in diameter or 10 meters in radius.
flower bed Area = 3.14*[tex]10^{2}[/tex]
flower bed Area = 314 [tex]m^{2}[/tex]
circle of sidewalk adds 3 meters
sidewalk circle area = 3.14*[tex]13^{2}[/tex]
sidewalk circle area = 530.66
subtract the flower bed area from the sidewalk area, and you have just the walk way it self.
530.66 - 314 = 216.66 [tex]m^{2}[/tex] for the sidewalk only
Here are two circles, Circle A and Circle D. Segment AD connects the two centers and is 10 inches long. Segment AD is a side to square ABCD. What is the area of the shaded region.
Answer:
the answer is, area of the square - a half of area of the circle
C=circle and S =square
radius of C is 10
so Area Of C is =
[tex]\pi r^{2} = \pi{10}^{2} = 100\pi[/tex]
area of S = 10×10 = 100
so the answer is
[tex]s - \frac{c}{2} = 100 - \frac{100\pi}{2} = 100 - 50\pi[/tex]

Answer:
In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.
Step-by-step explanation:
Remember Generalization is like an inference.
You need to write a statement that is based on the given information about Anna's shapes.
_______________________________________________________
If we look at Anna's shapes we have 2 quadrilaterals and 1 triangle.
Then, the "following" shapes have the same properties meaning 2 quads and 1 triangle.
We can go straightforwardly by saying the shapes that Anna chose are 2 quadrilaterals and 1 triangle.
Parallel sides are only shown on 2 of the shapes (the square and the parallelogram).
There are 3 triangles: 1 right, 1 obtuse, and 1 equilateral or acute.
______________________________________________________
Here's my generalization:
If we look at the shapes that Anna chose, we can identify 2 quadrilaterals and 1 triangle. The following shapes don't belong with the ones she chose because there are 2 triangles (equilateral and one right triangle). Then, we have a square with 2 sets of parallel lines which the parallelogram has. The other quadrilateral doesn't have any parallel lines which can't be a trapezoid either. In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.
D. When a number is subtracted from the numerator and denominator of 4/3 the result is more than 2/3. Find the number
Answer:
Let us solve this
We’ll do it by the elementary method
Suppose the original fraction be x/y
Given, x : y = 2:3 ……(i)
then y = 3/2x
Now , by condition,
(x-6)/y = 2/3 * x/y
=> (x-6)/y = 4/9 [ from (i) ]
=> x-6 = 4/9y = (4/9)(3/2)x = 2/3x
=> 3x-18 = 2x [cross multiplication]
=> x = 18
Your Answer: the numerator of the original fraction is = 18

I= balance*percentage/12
Therefore
I=17,565. 74*0.09/12
I=131.7
The final payment
F=I+B
F=131.7+17,565. 74
F=17697.5
Amount saved
AS=19*995.40 -17697.5
AS=1215.12
b) For the loan is paid off with payment 36 with a loan balance of $12,285. 66
I= balance*percentage/12
Therefore
I= 12,285. 66*0.09/12I92.142
I=92.142
Final payment
F=I+B
F=92.142+12377.80
F=12377.80
Amount saved
AS=13*995.40-12377.80
AS=$562.40
c) For the loan is paid off with payment 48 with a previous balance of $988. 9
I= balance*percentage/12
I= 988.09*0.09/12
I=7.41

What is the volume of the right rectangular prism? Enter your answer in the box.
Answer:
1000 cm²
Step-by-step explanation:
Given:
Length = 10 cmWidth = 12.5 cmHeight = 8 cmFormula:
[tex]\text{Volume = Length} \times \text{Width} \times \text{Height}[/tex]
Substitute the length, width, and the height of the prism to determine the volume of the prism.
[tex]\implies \text{Volume = 10} \times 12.5 \times 8[/tex]
Simplify the right hand side of the equation, as needed;
[tex]\implies \text{Volume = 10} \times 12.5 \times 8[/tex]
[tex]\implies \text{Volume =}\ 125 \times 8[/tex]
[tex]\implies \boxed{\text{Volume =}\ 1000 \ \text{cm}^{2} }[/tex]

598½
Step-by-step explanation:
use division method
Answer:
2 divided by 1197 equals 598 with a remainder of 1.
Step-by-step explanation:
There is also another way to do divison if it is confusing for others.
If you multiply 598 and 2 that equals 1196. That is the closest number that can go into 2 598 times. So what i am trying to say is that since the problem is 2 divided by 1197 you have to figure out what number you need to multiply that can go into two. So 2 divided by what equals 1197 OR 2 divided by what number can equal 1197 or any number that is close to 1197. So 598 times 2 equals 1196. With a remainder of 1
I hope this helps because this strategy worked for me when i first learned division so i hope this helps as well :)

Find the volume and surface area of the figure below.
The volume of the prism is determined as 1,416 m³ and the surface area of the prism is 664.8 m².
Volume of the prismThe volume of the prism is determined from the product of base area and slant height of the prism.
Base of the prism, A = ¹/₂bh = ¹/₂ x 12 x 20 = 120 m²
Volume = AL
where;
L is the slant heightL² = (12/2)² + (20.3/2)²
L² = 6² + 10.15²
L² = 139.0225
L = 11.8 m
V = AL
V = 120 x 11.8 = 1,416 m³

2. 24 cm^3
3. 540 cm^3
4. 1476 cm^3
Step-by-step explanation:
1. rectangular prism volume equation is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 5 x 8 x 15 and we get V = 600 cubic cm.
2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6 x 2 x 4 and we get V = 24 cubic cm
3. V = Bh, where B is the base area and h is the perpendicular height. V = 45(12). So, V = 540 cm^3
4. Same thing with this one: V = Bh. Substitute known values into this equation: V = 82(18), which means V = 1476 cm^3

Which of the following systems is dependent?

x − y = 2 and −2x 2y = −4
x − y = 2 and 3x − 3y = 2
x − y = 2 and −x − y = −2
The system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
As we know, if the two linear equations have the same coefficient of x and y they are dependent or if the graph of two linear equations is the same then the equations are dependent.
From the given options, we can see the system of equations:
x − y = 2 and −2x + 2y = −4 are the same equation.
Take the equation −2x + 2y = −4 and divide by -2 on both sides, we get:
x - y = 2
This is the same equation as x − y = 2
Thus, the system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.

the angle between the tangent AC and the radius BC is 90°
then Δ ABC is right
note that BC = 9 ( radius of circle )
using Pythagoras' identity in the right triangle
AC² + BC² = AB²
AC² + 9² = (9 + 6)² = 15²
AC² + 81 = 225 ( subtract 81 from both sides )
