A recent market survey indicated that 37% of the citizens in town would support a new coffee shop. The survey has a margin of error of
1.7%, and the population of the town is 36,170. Based on the survey, which statement about the number of people who would support for
a new coffee shop is true?
Based on the survey, we can say that between 12,776 and 14,000 citizens in the town would support a new coffee shop.
The margin of error is a measure of the uncertainty in the survey results. It is based on the sample size and the level of confidence desired. In this case, the margin of error is 1.7%.
This means that the actual percentage of citizens in the town who would support a new coffee shop could be as much as 1.7% higher or lower than the survey result of 37%.
To calculate the range of possible values for the percentage of citizens who would support a new coffee shop, we add and subtract the margin of error from the survey result:
37% + 1.7% = 38.7%
37% - 1.7% = 35.3%
Therefore, based on the survey, we can say that between 35.3% and 38.7% of the citizens in the town would support a new coffee shop.
To determine the number of people who would support a new coffee shop, we need to multiply the percentage by the population of the town:
35.3% of 36,170 = 12,776
38.7% of 36,170 = 14,000
Therefore, based on the survey, we can say that between 12,776 and 14,000 citizens in the town would support a new coffee shop.

Answer: (d)Answer:
ye D is correctStep-by-step explanation:
To combine the terms 12a + 26b - 4b - 16a, you first simplify the like terms. Add the coefficients of a terms and add the coefficients of b terms separately. You get 12a - 16a + 26b - 4b which results in -4a + 22b. Therefore, the correct answer is (c) -4a + 22b.
The two methods of expressing bearing can be interpreted using a rectangular coordinate system. Suppose that an observer for a radar station is located at the origin of a coordinate system. Find the bearing of an airplane located at the point (10,0). Express the bearing using both methods.
The angle in the rectangular coordinate system is 0 degrees, the compass bearing of the airplane is N (north).
The slope of the line can be found using the formula:
slope = (change in y-coordinate) / (change in x-coordinate)
In this case, the change in the y-coordinate is 0, and the change in the x-coordinate is 10. Therefore, the slope of the line is:
slope = (0 - 0) / (10 - 0) = 0
Since the slope of the line is 0, the line is horizontal, and the angle it makes with the x-axis is 0 degrees or 180 degrees. However, we need to determine which of these angles is the correct bearing of the airplane relative to the observer.
Since the airplane is in the positive x-axis, it lies in Quadrant I. In this quadrant, the angle that a line makes with the positive x-axis is measured counterclockwise from the positive x-axis.
Therefore, the angle that the line connecting the observer to the airplane makes with the positive x-axis is 0 degrees. This is the bearing of the airplane relative to the observer.
To express the bearing using the compass bearing method, we need to convert the angle from the rectangular coordinate system to the angle measured in degrees clockwise from the north direction.

18 divided by 5.5
PLEASE ANSWER FULL INSTRUCTIONS
Answer:
Step-by-step explanation:
To divide 18 by 5.5, we can use long division method as follows:
_________
5.5 | 18.0000
-16.5
------
1.5
We first divide 5.5 into the first digit of 18, which is 1. This gives us 0 as the whole number part of the quotient. We then multiply 0 by 5.5 to get 0, and subtract it from 1, which gives us 1.
We then bring down the next digit 0 and get 10. We then divide 5.5 into 15, which gives us 2 as the whole number part of the quotient. We then multiply 2 by 5.5 to get 11, and subtract it from 15, which gives us 4.
We then bring down the next digit 0 and get 40. We then divide 5.5 into 40, which gives us 7 as the whole number part of the quotient. We then multiply 7 by 5.5 to get 38.5, and subtract it from 40, which gives us 1.5.
Since there are no more digits to bring down and the remainder is less than the divisor 5.5, we can stop here. Therefore, the result of 18 divided by 5.5 is approximately 3.27, which we get from the quotient of 0.327 rounded to two decimal places.
So 18 divided by 5.5 is approximately 3.27 or 3.27 to two decimal places.

Reflecting a point across the x-axis changes the sign of its y-coordinate while keeping the x-coordinate intact. As such, Z' can be rewritten in terms of (x, -y).
If a rectangle shifts downward by five units and rightward by three units, the transformation rule can be expressed as: (x, y) → (x + 3, y - 5).
How to explain the informationConversely, the given equation for this specified action is: (x, y) → (x - 3, y - 4).
Similar but reversed in reflection across the y-axis, where instead it is the x-coordinate that sees its sign changed, given the conditions that the y-coordinate stays constant. Hence, the transformation can be stated as: (x, y) → (-x, y).
The same applies for a mathematical exchange when it comes to reflecting about the x-axis; here the y-coordinate has its signs reversed with no transition in the x-coordinate – simply put, we have as follows: (x, y) → (x, -y).
Finally, observing what occurs when rototating clockwise 270° around the origin reveals each point experiencing an equal shift from said anchor point; permitting us to formalize the related rule accurately as: (x, y) → (y, -x).

if parallel lines are but by a transversal, then alternate interior angles are congruent and (I have four choices here - alternate interior, complimentary, consecutive interior and exterior) angles are supplementary. can you help me pick the correct choice?
Answer:
When two parallel lines are intersected by a transversal, the alternate interior angles are the pairs of non-adjacent angles that are located between the two parallel lines and on opposite sides of the transversal. These angles are congruent, which means they have the same measure. The other type of angles mentioned in the statement, which are supplementary, are the pairs of adjacent angles that are located on the same side of the transversal and outside the parallel lines. These angles add up to 180 degrees.
The correct choice is "consecutive interior angles are supplementary."

Use normal approximation to estimate the probability of passing a true/false test of 70 questions if the minimum passing grade is 80% and all responses are random guesses.
The probability of passing the test by random guessing is 0.003%.
To estimate the probability of passing a true/false test of 70 questions, we can use the normal approximation to the binomial distribution. Since each question has only two possible outcomes (true or false), the binomial distribution can be used to calculate the probability of getting a certain number of correct answers out of 70.
The mean of the binomial distribution can be calculated as np, where n is the number of trials (70) and p is the probability of success (0.5, since the responses are random guesses). The standard deviation of the binomial distribution can be calculated as the square root of np*(1-p).
To find the probability of passing the test, we need to find the number of correct answers required to achieve a score of 80% or higher. Since 80% of 70 is 56, we need to get at least 56 questions correct.
Using the normal approximation, we can approximate the binomial distribution with a normal distribution with mean 35 and standard deviation 4.79. To find the probability of getting at least 56 questions correct, we can standardize the value (56-35)/4.79 = 4.02 and look up the probability in a standard normal table. The probability of getting at least 56 questions correct is approximately 0.00003.

Finding the height and width of the prismFrom the question, we have the following parameters that can be used in our computation:
V(x) = 3x^3 + x^2 - 2x + 3
Length = x + 1
This means that
Side area = Volume/Length
So, we have
Side area = (3x^3 + x^2 - 2x + 3)/(x + 1)
When evaluated, we have
Side area = 3x^2 - 2x + 3/(x + 1)
Ignoring the remainder, we have
Side area = 3x^2 - 2x
Factorize
Side area = x(3x - 2)
This means that
height = x and width = 3x - 2

Which of the following is the graph of the function shown below?
W.
X.
Y.
Z.
A.
X
B.
Y
C.
W
Answer:
Cannot be drawn directly.
Step-by-step explanation:
The graph of every function w = f (x, y, z) will be a surface in R 4, though it can't be drawn directly; however, slicing horizontally by w = c produces relations c = f (x, y, z) in x, y, and z whose graphs will be surfaces in 3-space which can be drawn. Therefore, the graph of the function shown above cannot be drawn directly.

According to the information, the ball returns to the ground about 13.6 feet away.
How to calculate how many feet away the ball returns to the ground?To calculate how many feet away the ball returns to the ground we have to consider that the ball starts 0 feet above the ground (assuming the ground level is the reference point, where h(x) = 0).
To find the maximum height, we need to find the vertex of the parabola, which occurs at
x = -b/2a
where,
a = -0.25
b = 3.4.
x = -3.4 / (2 * (-0.25)) = 6.8
So, the ball reaches a max height of h(6.8) = -0.25(6.8)^2 + 3.4(6.8) = 8.2 feet at a horizontal distance of 6.8 feet away from the club it was hit with.
To find when the ball returns to the ground, we set h(x) = 0 and solve for x:
0 = -0.25x^2 + 3.4x
0.25x(13.6 - x) = 0
x = 0 or x = 13.6
Since x = 0 is the starting point, the ball returns to the ground at x = 13.6 feet away from the club it was hit with.
Therefore, the ball returns to the ground about 13.6 feet away.
