The range of possible values that best describes the estimate for the population parameter is [0.16, 0.38]. Therefore, the correct answer is option D.

Given that, a sample proportion is 0.26.

In statistics, the sample proportion is an estimate for the population parameter. When given a sample proportion, the range of possible values that best describes the estimate for the population parameter is typically the 95% confidence interval for the sample proportion. The 95% confidence interval states that if the same sampling procedure is repeated on many samples, then 95% of the confidence intervals constructed this way will contain the true population parameter.

The 95% confidence interval for a sample proportion is given by [p-1.96√(pq/n), p+ 1.96√(pq/n)], where p is the sample proportion, q is the complement of the sample proportion (q = 1 − p), and n is the sample size.

In this case, the sample proportion given is 0.26, and so p = 0.26, q = 0.74, and the sample size can be assumed to be large (n ≥ 30). Substituting these values into the 95% confidence interval equation yields the range of possible values that best describes the estimate for the population parameter: [0.16, 0.38].

Therefore, the correct answer is option D.

[tex]|Huntrw6|[/tex]

Answer:  Option 'D' is correct.

Step-by-step explanation:

Since we have given that

x = ±6, y = 0

and x = 0 and y = ±12

And we need an equation which has above as an integer solutions.

So, it becomes,

Consider [tex]4x^2+y^2-144=0[/tex]

Put x = 0, we get

[tex]0+y^2=144\\\\y^2=144\\\\y=\sqrt{144}\\\\y=\pm 12[/tex]

Similarly,

Put y = 0,

[tex]4x^2+0=144\\\\4x^2=144\\\\x^2=\dfrac{144}{4}\\\\x^2=36\\\\\x=\pm 6[/tex]

Hence, Option 'D' is correct.

Answer:

5 slices

Step-by-step explanation:

The answer is D) 210 because arc eog is 150 and is the minor arc. A whole circle is 360 therefore 360-150=210

The measure of the major arc is found by calculating the circumference of the entire circle 2πr and then using the proportion that the angle of the major arc represents out of 360 degrees.

The measure of the major arc in a circle depends on the angle subtended by the arc at the center of the circle. If we define the angle Θ (theta) in degrees, that subtend the arc, the length of the major arc can be found by using the circumference of the entire circle, which is 2πr (where r is the radius), and the proportion of the circle that the major arc represents. Since the entire circle is 360 degrees, if the major arc corresponds to an angle Α, which is the complement of Θ (since Α + Θ = 360 degrees for the minor and major arcs together), the major arc length will be 2πr (Α/360). To summarize, if you're given the central angle of the minor arc or can otherwise determine the central angle for the major arc, you can use this proportion to calculate the arc length.

Step-by-step explanation:

If you think about it the graphed point is (0,0), so it is self explanatory that he works 0 hours and OBVIOUSLY he wont earn any money if he doesnt work.

The graph shows the amount of money Hachi earns at his job in relation to the number of hours he works. Hachi does not earn any money if he does not work.

A function is defined as a relation between the set of inputs having exactly one output each.

We can see that the graph linearly increases as the hour he worked and the money he earned will increase.

we know that the graphed point is (0,0),

He earned 10 money per hour of work.

so it is self-explanatory that he works 0 hours and obviously, he won't earn any money if he doesn't work.

Thus, Hachi does not earn any money if he does not work.

Answer:

The center of the circle is (-3 , 5) and the length of the radius is 9 units

Step-by-step explanation:

* Lets revise the standard form of the equation of the circle

- The center-radius form of the circle equation is in the format

 (x – h)² + (y – k)² = r², where the center is the point (h, k) and

 the radius is r.

- This form of the equation is helpful, because you can easily find

  the center and the radius.

* Now lets solve the problem

- The equation is (x + 3)² + (y - 5)² = 81

- By comparing the two equations

∵  (x – h)² + (y – k)² = r² and  (x + 3)² + (y - 5)² = 81

# x - h = x + 3

∴ -h = 3 ⇒ divide both sides by -1

∴ h = -3

# y - k = y - 5

∴ k = 5

# h and k are the coordinates of the center of the circle

∴ The center of the circle is (-3 , 5)

# r² = 81 ⇒ take √ for both sides

∴ r = 9

∴ The length of the radius = 9 units

* The center of the circle is (-3 , 5) and the length of the radius is 9 units

The center of the circle is at (-3, 5), and the radius of the circle is 9, determined by the given equation (x + 3)^2 + (y – 5)^2 = 81.

The student is asking about the equation of a circle and how to determine the coordinates of the center and the length of the radius. The given equation is (x + 3)2 + (y – 5)2 = 81. The general form of a circle's equation is (x - h)2 + (y - k)2 = r2, where (h, k) is the center and r is the radius.

To find the center of the circle, we look at the values h and k in the equation, which are the opposites of the constants added to x and y, respectively. Therefore, the center is at (-3, 5). To find the radius of the circle, we take the square root of the number on the right side of the equation. The square root of 81 is 9, so the radius is 9.

Answer:

660 ft³

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated using the formula

V = lbh ( l is length, b is breadth and h is height )

The dimensions must be in the same units, thus we need to change length into feet.

l = 4 × 3 = 12 ft ( 1 yard = 3 feet )

b = 5 ft and h = 11 ft

V = 12 × 5 × 11 = 660 ft³

Final answer:

Convert the length from yards to feet, then calculate the volume by multiplying length, width, and height to get 660 cubic feet.

Explanation:

To find the volume of a rectangular prism, you multiply the length, width, and height together. However, notice that in the problem the lengths are not all in the same units; the length is given in yards and the width and height in feet. First, we need to convert yards to feet so that all dimensions are in the same units, using the conversion factor that 1 yard is equal to 3 feet.

After converting, the length will be:

4 yd = 4 x 3 ft = 12 ft

Then you can calculate the volume:

Volume = length x width x height

= 12 ft x 5 ft x 11 ft

= 660 cubic feet

Step-by-step explanation:

It is given from the figure, the side of the regular hexagonal pyramid is 3 m, slant height is 6.2 m and height is 5.6 m.

The formula for Surface area of the regular hexagonal pyramid is:

[tex]SA=\frac{pl}{2}+B[/tex]

where B is the area of the base, p is the perimeter and l is the slant height.

Now, the perimeter can be found as:

[tex]P=6{\times}3[/tex]

[tex]P=18 m[/tex]

And, the area of the base is:

[tex]B=\frac{3\sqrt{3}s^2}{2}[/tex]

Substituting the value of s in the above formula, we get

[tex]B=\frac{3\sqrt{3}(3)^2}{2}[/tex]

[tex]B=23.382m^2[/tex]

Now, substituting the values of B, and P in the formula of Surface area, we get

[tex]SA=\frac{18{\times}6.2}{2}+23.382[/tex]

[tex]SA=79.18m^2[/tex]

Thus, the Surface area of the regular hexagonal pyramid is [tex]79.18m^2[/tex].

Hence,  option B is correct.

Without a specific figure, it's not possible to definitively answer which parallel lines statement is true. However, parallel lines are equidistant and never meet, contrasting with mutually perpendicular lines, which intersect at right angles.

Given the various contextual clues from the fragments presented, it seems that the question concerns the properties of parallel lines and their behavior in a geometric or physical context, possibly relating to vectors, navigation, or electrical currents. However, without a specific figure or more detailed information, it's not possible to accurately determine which statement is true regarding the parallel lines in the figure.

For parallel lines, we know that they are equidistant from each other at all points and will never meet, no matter how far they are extended. This trait could relate to the x-axis alignment if we assume the lines are coplanar. On the other hand, if lines are mutually perpendicular, they will intersect at right angles to each other and therefore are not parallel.

D) AB is parallel to CD.

To understand why this statement is true, let's analyze the properties of a trapezium and the given figure.

A trapezium is a quadrilateral with one pair of parallel sides. In this case, AB and CD are the sides of the trapezium.

Looking at the given figure, we can see that AB is the upper side and CD is the base of the trapezium. Since AB and CD are not intersecting each other and are on opposite sides of the trapezium, they must be parallel to each other.

Therefore, the correct parallel lines statement is that AB is parallel to CD.

To summarize:
- AB and CD are the sides of the trapezium.
- AB is the upper side and CD is the base.
- AB and CD are not intersecting and are on opposite sides of the trapezium.
- Therefore, AB is parallel to CD.

Answer:

B

Step-by-step explanation:

$40 is the flat fee of hooking a vehicle. It does not depend on m, miles towed.

$1.70 depends on miles towed, m. So if m miles are towed, the towing fee would be 1.70 * m, or 1.70m.

THAT, would be added to the initial fixed me of $40.

Hence, total charges, c, would be 40 + 1.70m

Answer choice B is right.

The correct equation that represents the total charges from Eddies towing company, taking into account the fixed hooking fee and the per mile charge, is c = 40 + 1.70m. This equation combines the constant fee of $40 and the $1.70 charge per mile, where the number of miles is represented by m.

The question is about finding the equation that represents the total charges, c, from Eddies towing company given the number of miles a vehicle is towed, m. Since the company charges a fixed fee of $40 for hooking the vehicle and an additional $1.70 for each mile the vehicle is towed, the correct equation should present these two charges. The fixed fee doesn't change with the number of miles, so it remains constant at $40. On the other hand, the per mile charge depends on how many miles are towed, hence it'll be multiplied with the number of miles, m. That results in an equation with the form of c = 40 + 1.70m. Therefore, the correct answer is option B.
