Answer:
64.29%
Step-by-step explanation:
What is happening from line a to
line b?
a. – 12x – 24 = -2x + 36
B. – 10x - 24 = 36
Help none of this makes sense lol.
Line B changes because you are taking -2x and adding it to both sides to get -10x -24 = 36
You do this to get the X on one side of the equation, hope this helped you :)

A poll asked 1057 American adults if they believe there was a conspiracy in the assassination of President Kennedy, and found that 614 believe there was a conspiracy. Estimate the proportion of Americans who believe in this conspiracy using a 95% confidence interval. Round to three decimal places.
Answer:
The 95% confidence interval of the proportion of Americans who believe in the conspiracy is [tex] 0.551< p < 0.610[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n =1057
The number that believe there was a conspiracy is k = 614
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{614}{1057 }[/tex]
=> [tex]\^ p = 0.5809[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.96 * \sqrt{\frac{0.5809 (1- 0.5809)}{1057} } [/tex]
=> [tex]E = 0.02975 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex] 0.5809 - 0.02975< p < 0.5809 + 0.02975[/tex]
=> [tex] 0.551< p < 0.610[/tex]

shape of the pond is shaped somewhat like a triangle. He claims that he can approximate the perimeter of the pond without doing any measurement of the actual pond or on the diagram. What assumption would Paul need to make in order to justify his claim? B. Based on the assumption in part A, determine the approximate length of side c of the pond. Explain your reasoning in at least two sentences. C. Determine the approximate perimeter of the pond. Explain your reasoning
Answer:
A) the curves are ellipses
B) 161 yards
C) 366 yards
Step-by-step explanation:
A) The general shape of the side marked c has the appearance of two quarter-ellipses. The major axis is approximately 125 yards, and the minor axis is approximately 80 yards. Paul could assume that the curves are quarter-ellipses.
B) For an ellipse with this eccentricity, its perimeter is within 2% of that of a circle with a diameter equal to the average of these dimensions.*
So, the approximate length of side c is ...
c ≈ π(80 +125)/4 ≈ 161 . . . . yards; length of side c
C) The perimeter of the pond is the sum of the side lengths, so will be ...
80 yds + 125 yds + 161 yds = 366 yds . . . pond perimeter
Indian mathematician Ramanujan developed an approximate formula for the circumference of an ellipse, which would otherwise need to be computed using an elliptic integral. it is ...
C = π(a+b)(1 + 3λ²/(10 +√(4 -3λ²)) where λ = (a -b)/(a +b) and a, b are the semi-axis lengths.
For this ellipse, λ = 9/41, so the last factor is about 1.01208313. Using this factor, the circumference is expected to be good to about 7 significant digits. Continuing the calculation, we find C ≈ 325.904 . . . . circumference of an ellipse 125 yd long by 80 yd wide
This is twice the length we imagine for c, so c ≈ 163 yards. As we said, the approximation used above is within 2% of this value.
The attachment shows the shape if the curve is actually an ellipse.

The points O, P, Q and R all lie on the same line segment, in that order, such that the
ratio of OP : PQ: QR is equal to 4:5: 2. If OR = 11, find QR.
9514 1404 393
Answer:
QR = 2
Step-by-step explanation:
The sum of ratio units is 4+5+2 = 11, corresponding to the total length OP +PQ +QR = OR. OR is also 11, so each ratio unit stands for 11/11 = 1 length unit.
The number of ratio units associated with QR is 2, so the length of QR is 2.

A coordinate grid is placed on top of a city map, showing the following characteristics:
• Washington Avenue is represented by the line x = 3.
.
Lincoln Avenue passes through the point (5,2).
Lincoln Avenue and Washington Avenue are parallel.
line
Lincoln Avenue is represented by the line
Answer:
Lincoln Avenue is represented by the line [tex] x = 5 [/tex], which is a VERTICAL LINE.
Step-by-step explanation:
The equation of the line of Washington Avenue, x = 3, suggests that the line is a vertical line, since a vertical line takes the form of x = k, where k is the value x would always take and also it is the x-intercept.
Given that Lincoln Avenue passes through the point (5, 2), and its line is parallel to that of Washington Avenue, it means that the line do not intercept each other, and Lincoln Avenue is also a vertical line.
Therefore, if Lincoln Avenue passes through (5, 2), its line can be represented also in the form, x = k. Where, k is the value that x would always take, and also, it is the x-intercept. x would always be 5 even when y changes.
Therefore, the equation of the line that represents Lincoln Avenue would be:
✅ [tex] x = 5 [/tex]
✅This is also a Vertical line.
2/3 divided by 4 in simplest form
Answer:
it's 1//6
Step-by-step explanation:
I used the calculator, and its 1/6
Note: Make Me BRAINLIEST PLZZ..
Answer:
0.16 or 1/6
Explanation:
2/3 divided by 4 is 0.16666666666
0.16666... = 0.1 + 0.06666...
x = 0.06666... / · 10
10 x = 0.66666...
10 x = 0.6 + 0.6666...
10 x = 0.6 + x
9 x = 0.6
x = 0.6/9 = 6/90 = 1/15
0.166666... = 0.1 + 1/15 = 1/10 + 1/15 = (2 + 3) / 30 = 5/30 = 1/6

Answer:
We verified that the equation [tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex] has both sides equal.
Step-by-step explanation:
We need to solve and verify: [tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex]
Solving:
[tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex]
Converting into improper fractions

Converting division sign into multiplication and reversing 3/2 i.e
[tex]\frac{15}{2}\times\frac{2}{3}=5[/tex]
Now simplifying
[tex]\frac{15}{3}=5 \\5=5[/tex]
So, We verified that the equation [tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex] has both sides equal.

A scale model drawing of a backyard is 6 centimeters wide and 8 centimeters long. The scale model uses a scale in which 2 centimeters represents 1.6 meters. What is the area of the actual backyard? 11.52 m² 22.40 m² 30.72 m² 48 m²
Answer:
First you need to divide 1.6 by 2 to get .8 then multiply
.8 x 6 = 4.8
.8 x 8 = 6.4
Then multiply 4.8 by 6.4 and get 30.72
The area of the actual backyard is 30.72 [tex]m^2[/tex]
Calculation of the area:Since A scale model drawing of a backyard is 6 centimeters wide and 8 centimeters long. The scale model uses a scale in which 2 centimeters represents 1.6 meters.
Here we were required to divide 1.6 by 2 so that 0.8 could come
Now
[tex]= (.8 \times 6) \times (.8 \times 8) \\\\= 4.8 \times 6.4[/tex]

Suppose a box contains 3 defective light bulbs and 12 good bulbs. Two bulbs are chosen separately from the box without replacement. What is the probability that one of two bulbs drawn is defective and one is not?
Answer:
[tex]Probability = \frac{12}{35}[/tex]
Step-by-step explanation:
Given
Represent Defective Bulbs with D and non good bulbs with G
[tex]D = 3[/tex]
[tex]G = 12[/tex]
The probability that one is defective and the other is not can be represented with: (D and G) or (G and D)
Which means that the defective is selected first, then the good one or the good one is selected first, then the defective one.
This is then calculated as:
[tex]Probability = \frac{n(D}{Total} * \frac{n(G)}{Total - 1} + \frac{n(G}{Total} * \frac{n(D)}{Total - 1}[/tex]
We used Total - 1 on second selections because it is a probability without replacement
[tex]Probability = \frac{3}{15} * \frac{12}{15- 1} + \frac{12}{15} * \frac{3}{15- 1}[/tex]
[tex]Probability = \frac{3}{15} * \frac{12}{14} + \frac{12}{15} * \frac{3}{14}[/tex]
[tex]Probability = \frac{1}{5} * \frac{6}{7} + \frac{2}{5} * \frac{3}{7}[/tex]
[tex]Probability = \frac{6}{35} + \frac{6}{35}[/tex]
[tex]Probability = \frac{12}{35}[/tex]
