An input value that would produce the same output value for the first functions on the graph is 0. Also, an input value that would produce the same output value for the second functions on the graph is 3.
How to determine the correct input value?In this exercise, you are required to determine the input value that would produce the same output value for the two functions on the graph. This ultimately implies that, the two functions would be equated as shown below.
From the information provided above, the two functions include the following:
f(x) = -2/3(x + 1)
g(x) = 1/3(x - 2)
Equating the two equations, we have:
f(x) = g(x)
-2/3(x + 1) = 1/3(x - 2)
-2x/3 -2/3 = x/3 - 2/3
-2x/3 - x/3 = - 2/3 + 2/3
x = 0.
For the second function on the graph, the coordinates are as follows:
f(x) = (-3, 3), (0, 1), (3, -1)
g(x) = (-3, -3), (0, -2), (3, -1)
Therefore, the above function produces the same input value (x) at point 3.

Write a proof for the statement.
If a quadrilateral is a square, then the quadrilateral is a rectangle.
Proved that if a quadrilateral is a square then the quadrilateral is also a rectangle.
Explain quadrilaterals.A quadrilateral is a closed shape created by uniting four points, any three of which cannot be collinear. Four sides, four angles, and four vertices make up a quadrilateral.
Quadrilaterals have a few characteristics. The list is as follows.
Each side has four sides.
Each of them has four vertices.
Two diagonals are present.
360 degrees is the sum of all interior angles.
Given, to prove if a quadrilateral is a square, then the quadrilateral is a rectangle.
The Square has four equal sides, and all four angles are right-angled.
Rectangle has equal opposite sides, and all four angles are the right angle.
Here, the two sides of the square can be increased to form a rectangle.
Hence, proved that if a quadrilateral is a square then the quadrilateral is also a rectangle.

What is the largest multiple of 30 which is less than 520?
The largest multiple of 30 that is less than the number, 520, can be found to be 510.
How to find the multiple?To find the largest multiple that 30 has, which is also less than 520, first find the number of times that 30 can go into 520:
= 520 / 30
= 17.333
Then use this number to find the largest multiple below 520 by rounding 17.33 downwards to 17.
The multiple of 30 that is the largest and below 520 is then:

Fewer than %97 of adults have a cell phone. In a reputable poll of 1160 adults, %88
said that they have a cell phone. Find the value of the test statistic
The value of the test statistic of the hypotheses is; -17.969
How to find the test statistic?
The test statistic is defined as a number, calculated from a statistical test, which is used to find if your data could have occurred under the null hypothesis.
We are given;
Sample size; n = 1160
Sample proportion; p^ = 88% = 0.88
Population proportion; p = 97% = 0.97
The claim is about the population proportion (p) in the hypotheses. Since we are told that fewer than 97% of adults have a cell phone, then the claim is; p < 0.97
The null hypothesis is expressed as;
H₀: p = 0.97
The alternative hypothesis is expressed as;
Hₐ: p < 0.97
The value of the test-statistic is gotten from the formula;
z = (p^ - p)/(√(p(1 - p)/n))
z = (0.88 - 0.97)/(√(0.97(1 - 0.97)/1160))
z = -17.969

in 2017, a journal reported on trends in sugar-sweetened beverage (SSB) consumption. A random sample of youths aged 12 to 19 years old were asked to monitor all food and beverages consumed in a 24-hour period. The study was done in 2005 and repeated in 2014. The numbers who consumed a sugary beverage such as soda or fruit juice in a day are shown in the accompanying table
The 95% confidence interval for the distribution of the difference of proportions, using the z-distribution, is given as follows:
(0.11, 0.146).
How to find the confidence interval for the difference of proportions?The first step is finding the proportion and standard error for each sample, as follows:
2005: [tex]n = 3486 + 2248 = 5734, p_1 = \frac{3486}{5734} = 0.608, s_1 = \sqrt{\frac{0.608(0.392)}{5734}} = 0.0064[/tex]2014: [tex]n = 2754 + 2980 = 5734, p_2 = \frac{2754}{5734} = 0.48, s_2 = \sqrt{\frac{0.48(0.52)}{5734}} = 0.0066[/tex]For the distribution of differences, the mean and the standard error are given as follows:
p = 0.608 - 0.48 = 0.128.s = sqrt(0.0064² + 0.0066²) = 0.0092.The z-distribution is used as we are working with proportions, hence the bounds of the interval are given as follows:
p ± zs.
The critical value for a 95% confidence interval with the z-distribution is of z = 1.96.
Hence the lower bound of the interval is:
0.128 - 1.96 x 0.0092 = 0.11.
The upper bound of the interval is:
0.128 + 1.96 x 0.0092 = 0.146.
What is the missing information?
The information regarding each sample is given by the image at the end of the answer, and the problem asks for the 95% confidence interval for the differences.

Percentage
150% of Dalia's height
25% of Dalia's height
100% of Dalia's height
Answer:
150% = 132 cm, 25%= 22 cm, 100%= 88 cm
Given:
Height of Odalis = 132 cm
This height is 150%
Divided into 6 parts.
To find: Different percentages of Dallas's Height
Solution:
Dalia's Height = Odalis height * (100/150)
= 132 cm * (2/3)
= 88 cm.
150% of Dallas's Height is 132 cm.
25% of Dalia's Height = 1/4 * 88 = 22 cm
100% of Dalia's Height = 88 cm.
This can also be taken by parts.
6 parts = 150%
1 part = 150/6 = 25%
And 6 parts = 132 cm,
so, 1 part = 132/6 = 22cm.
so , 25% = 1 part= 22cm.
100% = 4 parts = 22*4 = 88 cm.
150% = 6 parts = 22*6 = 132 cm.
Hence, 150% = 132 cm
25%= 22 cm
100%= 88 cm

x^2 = –3y
y^2 = –3x
x^2 = 12y
y^2 = 12x
The equation of the parabola whose focus is at (3, 0) and directrix at x = - 3 is y² = 12 · x. (Correct choice: D)
How to derive the equation of the parabola
In this problem we need to determine the equation of a parabola based on the information of the focus and the directrix. The vertex form of the parabola is described below:
4 · p · (x - h) = (y - k)²
Where p is the distance from the vertex to the focus. The coordinates of the vertex is the midpoint of the line segment of the least distance between the directrix and the focus.
First, determine the coordinates of the vertex:
(h, k) = 0.5 · (- 3, 0) + 0.5 · (3, 0)
(h, k) = (0, 0)
Second, calculate the distance from the vertex to the focus:
