Answer:
x = 2, y = 1
Step-by-step explanation:
2x+3y = 7
y = 6x -11
Substitute the second equation in for y in the first equation
2x +3( 6x - 11) = 7
Distribute
2x+18x - 33 = 7
Combine like terms
20x - 33 = 7
Add 33 to each side
20x -33+33= 7+33
20x = 40
Divide each side by 20
20x/20 = 40/20
x= 2

A circle is inscribed with quadrilateral A B C D.
Let the measure of Arc B C D = a°. Because Arc B C D and Arc B A D form a circle, and a circle measures 360°, the measure of Arc B A D is 360 – a°. Because of the ________ theorem, m∠A = StartFraction a Over 2 EndFraction degrees and m∠C = StartFraction 360 minus a Over 2 EndFraction degrees. The sum of the measures of angles A and C is (StartFraction a Over 2 EndFraction) + StartFraction 360 minus a Over 2 EndFraction degrees, which is equal to StartFraction 360 degrees Over 2 EndFraction, or 180°. Therefore, angles A and C are supplementary because their measures add up to 180°. Angles B and D are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠A + m∠C + m∠B + m∠D = 360°, and using substitution, 180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°.
What is the missing information in the paragraph proof?
inscribed angle

Answer:
A. Inscribed Angle Theorem
Step-by-step explanation:
Because the angles are inscribed in the circle, the angle lie on arcs which mean that the angles have to add up to 360 degrees just like a circle is 360 degrees, making it a quadrilateral that is inscribed!

The missing information in the paragraph proof is inscribed angle theorem that if an angle is inscribed in a circle, the measure of the inscribed angle is half the measure of the intercepted arc.
What is inscribed angle ?Inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
We have,
Quadrilateral [tex]A B C D[/tex] inscribed in Circle.
Measure of Arc [tex]B C D = a^0[/tex].
Arc [tex]B C D[/tex] and Arc [tex]B A D[/tex] form a circle, and a circle measures [tex]360^0[/tex],
Measure of Arc [tex]B A D = 360 - a^0[/tex]
Because of the theorem that if an angle is inscribed in a circle, the measure of the inscribed angle is half the measure of the intercepted arc.
Therefore,
[tex]\angle A = \frac{a}{2}^0[/tex] and
[tex]\angle C = (\frac{360-a}{2}) ^0[/tex]
The sum of the measures of angles [tex]A[/tex] and [tex]C[/tex] is,
[tex]\angle A + \angle C = \frac{a}{2}^0 +(\frac{360-a}{2}) ^0=180^0[/tex]
Therefore, angles [tex]A[/tex] and [tex]C[/tex] are supplementary because their measures add up to [tex]180^0[/tex].
Angles [tex]B[/tex] and [tex]D[/tex] are supplementary because the sum of the measures of the angles in a quadrilateral is[tex]360^0[/tex].
[tex]\angle A + \angle C + \angle B + \angle D = 360^0[/tex]
and using substitution,
[tex]180^0 + \angle B + \angle D = 360^0[/tex]
So,
[tex]\angle B + \angle D = 180^0[/tex]
So, from the above provided proof we can say that the missing information in the proof was inscribed angle theorem.
Hence, we can say that the missing information in the paragraph proof is inscribed angle theorem that if an angle is inscribed in a circle, the measure of the inscribed angle is half the measure of the intercepted arc.

A sector with an area of 26pie cm^2 has a radius of 6 cm. What is the central angle measure of the sector in radians?
Answer:
The central angle measure of the sector in radians is [tex]\theta=\frac{13}{9}[/tex].
Step-by-step explanation:
A sector of a circle is the portion of a circle enclosed by two radii and an arc. It resembles a "pizza" slice.
The area of a sector when the central angle is in radians is given by
[tex]A=(\frac{\theta}{2})\cdot r^2[/tex]
where
r = radius
θ = central angle in radians
We know that the area of the sector is [tex]26 \:cm^2[/tex] and the radius is 6 cm. Applying the above formula and solving for the central angle ([tex]\theta[/tex]) we get that
[tex]26=(\frac{\theta}{2})\cdot (6)^2\\\\\left(\frac{\theta}{2}\right)\left(6\right)^2=26\\\\\frac{\frac{\theta}{2}\cdot \:6^2}{36}=\frac{26}{36}\\\\\frac{\theta}{2}=\frac{13}{18}\\\\\theta=\frac{13}{9}[/tex]

There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
Answer:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
Step-by-step explanation:
The correct situation is the third one, this is because the expression we have is:
[tex]30+4x=70+2x[/tex]
let's take the left side as the charge of the company limo A, and the left side as the charge of limo B.
Since 'x' is the number of people, the left side tells us that limo A charges $4 per person (hence the 4x) and adds an additional $30 (hence the 30 added on the left side).
And the right side tells us that limo B charges $2 per person (hence the 2x) and adds an additional $70 (hence the 70 added on the right side).
And since we have an equal sign this means that the expression represents the number of people that can ride and will pay an equal amount in each company.
This is the situation that the third option describes:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?

-The numerator of the expression is 5 and the sum of x and y
-The denominator is the product of -8 and x
Answer:
[tex]\frac{5(x+y)}{-8x}[/tex]
Step-by-step explanation:
Given the description below;
-The expression is quotient of 2 quantities
-The numerator of the expression is 5 and the sum of x and y
-The denominator is the product of -8 and x
Let the given two quantities be a and b
The quotient of the expression will be expressed as [tex]\frac{a}{b}[/tex] where 'a' is the numerator and 'b' is the denominator
If the numerator of the expression is 5 and the sum of x and y , then;
[tex]a = 5(x+y)[/tex]
If the denominator is the product of -8 and x, then;
[tex]b =-8x[/tex]
The quotient of both expression will be [tex]\frac{a}{b} = \frac{5(x+y)}{-8x}[/tex]
The expression that fits the description is [tex]\frac{5(x+y)}{-8x}[/tex]

A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.32 hours, with a standard deviation of 1.83 hours.
Construct and interpret a 95% confidence interval for the mean difference in leisure time between adults with no children and adults with children (μ1 - μ2).
Answer:
95% confidence interval for the mean difference in leisure time between adults with no children and adults with children (μ1 - μ2).
(0.4144 , 2.3256)
Step-by-step explanation:
Given sample size 'n' =n₁ = n₂ = 40
The mean of the first sample (x₁⁻) = 5.69 hours
The standard deviation of the first sample (S₁)= 2.42 hours
The mean of the second sample( x₂⁻) = 4.32 hours
The standard deviation of the second sample (S₂)= 1.83 hours
95% of confidence intervals for (μ₁ - μ₂)are determined by
[tex](X^{-} _{1} - X^{-} _{2} - t_{\frac{\alpha }{2} } Se(X^{-} _{1} - X^{-} _{2} ) , X^{-} _{1} - X^{-} _{2} + t_{\frac{\alpha }{2} } se(X^{-} _{1} - X^{-} _{2} ))[/tex]
where
The standard error of the difference between two means
[tex]se(X^{-} _{1} - X^{-} _{2} ) = \sqrt{\frac{S^{2} _{1} }{n_{1} }+\frac{S^{2} _{2} }{n_{2} } }[/tex]
[tex]se(X^{-} _{1} - X^{-} _{2} ) = \sqrt{\frac{(2.42)^2 }{40 }+\frac{(1.83)^2 }{40 } }[/tex]
[tex]se(X^{-} _{1} - X^{-} _{2} ) = \sqrt{0.2301325} = 0.47972[/tex]
Degrees of freedom γ = n₁ +n₂ -2 = 40+40 -2 =78
[tex]t_{\frac{\alpha }{2} } = t_{\frac{0.05}{2} } = t_{0.025}[/tex]
t₀.₀₂₅ = 1.992
95% of confidence intervals for (μ₁ - μ₂)are determined by
[tex](X^{-} _{1} - X^{-} _{2} - t_{\frac{\alpha }{2} } Se(X^{-} _{1} - X^{-} _{2} ) , X^{-} _{1} - X^{-} _{2} + t_{\frac{\alpha }{2} } se(X^{-} _{1} - X^{-} _{2} ))[/tex]
(5.69 -4.32)- 1.992(0.47972)), (5.69-4.32)+1.992(0.47972))
(1.37 -0.9556 , 1.37+0.9556)
(0.4144 , 2.3256)
Conclusion:-
95% confidence interval for the mean difference in leisure time between adults with no children and adults with children (μ1 - μ2).
(0.4144 , 2.3256)
Following are the calculation to the confidence interval:
Given:

To find:
confidence interval=?
Solution:
[tex]\to a=0.1\\\\ \to Z(0.05)=1.645[/tex] (from standard normal table)
Calculating the confidence interval when its value is [tex]95\%[/tex]:
[tex]\to (\bar{x_1}-\bar{x_2}) \pm Z \times \sqrt{(\frac{s^2_{1}}{n_1}+ \frac{s^2_{2}}{n_2})}[/tex]
[tex]\to (5.69-4.32)\pm 1.645 \times \sqrt{(\frac{2.42^2}{40}+\frac{1.83^2}{40})}\\\\\to (1.37)\pm 1.645 \times \sqrt{(\frac{5.8564}{40}+\frac{3.3489}{40})}\\\\\to (1.37)\pm 1.645 \times \sqrt{(\frac{5.8564+3.3489}{40})}\\\\\to (1.37)\pm 1.645 \times \sqrt{(\frac{9.2053}{40})}\\\\\to (1.37)\pm 1.645 \times \sqrt{0.2301325}\\\\\to (1.37)\pm 1.645 \times 0.4797212 \\\\\to (1.37)\pm 0.789\\\\\to (2.159, 0.581 )[/tex]

find the measure of the smallest angle of the triangle whose sides have lengths 6,9, and 11
Answer:
The smallest angle of the triangle is 33.030°.
Step-by-step explanation:
The angles of triangle can be determined with the help of the Law of Cosine and the fact that sum of all angles equals to 180°:
[tex]\cos A = -\frac{6^{2}-9^{2}-11^{2}}{2\cdot (9)\cdot (11)}[/tex]
[tex]\cos A = 0.838[/tex]
[tex]A \approx 33.030^{\circ}[/tex]
[tex]\cos B = -\frac{9^{2}-6^{2}-11^{2}}{2\cdot (6)\cdot (11)}[/tex]
[tex]\cos B = 0.575[/tex]
[tex]B \approx 54.847^{\circ}[/tex]
[tex]C = 180^{\circ} - A - B[/tex]
[tex]C = 180^{\circ} - 33.030^{\circ} - 54.847^{\circ}[/tex]
[tex]C = 92.123^{\circ}[/tex]
The smallest angle of the triangle is 33.030°.

What is the solution to |10x|greater than -2
Answer:
The solution is: [tex](-\infty, \infty)[/tex], that is, all real values of x.
Step-by-step explanation:
The modulus of a value x(|x|) is the distance of x to the origin.
A distance is a positive measure, or zero, so |x| is never a negative value.
In this problem:
|10x| > -2
Remembering that the modulus is never negative, which means that for every value of x in the real set, |10x| > -2.
So the solution is: [tex](-\infty, \infty)[/tex], that is, all real values of x.
