Answer:
Step-by-step explanation:
The results do not apply to any population because this was a convenience sample.
The confidence interval (0.53, 0.72) applies only to the population of those students who drive to the college. The correct answer is D.
The confidence interval is a statistical measure used to estimate an unknown population parameter, such as the proportion of students who support the building of a multi-level parking structure.
In this case, the students conducting the survey set up a table near the student parking lot and asked students who passed by to complete the survey. Therefore, the sample used for the survey consists only of students who use the student parking lot.
Since the survey was conducted exclusively among students who use the parking lot, the results and the subsequent confidence interval can only be generalized to that specific population.
The confidence interval (0.53, 0.72) represents the estimated range of proportions of students who support the parking structure within the population of students who drive to the college. It cannot be extended to the entire student body, students who do not use the parking lot, or any other population beyond those who drive to the college.
The correct answer is D.

XZ¯¯¯¯¯¯¯¯ has a point Y between points X and Z. XY=17, YZ=4x+9, and XZ=11x−9.
Applying the segment addition postulate, the value of x = 5.
What is the Segment Addition Postulate?According to the segment addition postulate, if three lines, X, Y, and Z are collinear points, that is they lie on a straight line such that Y is between points X and Z, then the sum of the lengths of segments XY and YZ would be equal to the length of segment XZ.
Therefore:
XY + YZ = XZ [segment addition postulate]
Given:
XY = 17
YZ = 4x + 9
XZ = 11x − 9.
Substitute
17 + 4x + 9 = 11x - 9
26 + 4x = 11x - 9
26 + 9 = 11x - 4x

The solution with a potential fraction remainder for the given fraction, 3.8/21.85, is 0.
How to find the remainder?By shifting the decimal point 1 places to the right, you can convert the divisor 3.8 to a whole number. Then, move the decimal point in the dividend by one place to the right, keeping the same position.
what do you understand by remainder ?The value remaining after division is known as the Remainder. After division, we are left with a value if a number (dividend) cannot be divided entirely by another number (divisor). The remaining is the name for this amount.

The value of x should be equal to 23
Given
Angle at the top is 86
also equation 3x + 17
The lines are parallel
We know if a transverse line is drawn across two parallel lines then 3 types of angles would form namely Corresponding angle, alternate angle, Opposite angle.
From the geometry the angle 86 and the equations 3x + 17 are alternative angles.
Since alternative angles are equal 86 will be equal to 3x + 17
Now equating both
86 = 3x + 17
86 - 17 = 3x
69 = 3x
x = 23

The company will sell new shares of equity via a general cash offering toraise the needed funds. If the offer price is $35 per share and the company'sunderwriters charge a 11 percent spread, how many shares need to be sold?
Solution
Explanation:
Total Finance Needed = $40,000,000
Offer price per share = $35 per share
Charges of underwriter = 11%
Total Number of shares needed to be sold = ( $40,000,000 / $35 ) x 111%
Total Number of shares needed to be sold = 1,142,857 x 111%
Total Number of shares needed to be sold = 1,267,571 shares
The Whistling Straits Corporation needs 1,267,571 shares to raise $40 million

GARDENING Molly's school is planning a school-based community garden with the diagram shownIf the school has 64 yards of fencing for the rectangular garden, use a system of equations and a graphing calculator to find the value of Then find the dimensions of the garden.
The value of x is 5 yards and the length and width of the garden is 20 yards and 12 yards respectively.
Given, the school has 64 yards of fencing for the rectangular garden.
we know that, the perimeter of the rectangle is the sum of twice the length and twice the width.
length (l) = x²-5
width (w) = 4x-8
therefore, 2(l+w) = 64
⇒ 2(x²-5+4x-8) = 64
⇒ 2(x²+4x-13) = 64
⇒ 2x²+8x-26 = 64
⇒2x²+8x-26-64 = 0
⇒2x²+8x-90 = 0
divide the equation by 2.
⇒ x²+4x-45=0
⇒ x²+9x-5x-45 = 0
⇒ x(x+9) - 5(x+9) = 0
⇒ (x+9) (x-5)
⇒ x = -9 or x = 5
therefore, x cannot be negative,
hence x = 5 yards.
therefore, l = x²-5
l = 5² - 5
l = 25-5
l = 20 yards.
w = 4x-8
w = 4(5) - 8
w = 20-8
w = 12 yards.
Hence we get the value of x as 5 yards and the dimensions of the garden as 20 yards by 12 yards,

Step-by-step explanation: 7 timestables
Answer:
1/7=4/28=8/56
Step-by-step explanation:
From the pattern of the question we can see that the numerator of the second fraction is 4 and the previous fraction's numerator is 1 that means the fraction has been multiplied by 4. Therefore multiplying the numerator and denominator results in the answer 4/28. For the last fraction we can see that the denominator is 56 and is the double of 28 therefore doubling the whole second fraction we get our answer as 8/56. Overall equating all the three fractions we get the same answer 1/7 after minimizing the fraction.
