The angle measurement of T is 80°.
What is an angle measurement?When two lines or rays intersect at a common point, an angle is formed. The common point is referred to as the vertex. An angle measure in geometry is the measurement of the angle formed by two rays or arms at a common vertex.Here given,
∠Q = (9x - 17)°
∠R = (4x + 28)°
Since ∠Q and ∠R are co-interior angles in parallel lines.
∠Q + ∠R = 180°
So,
(9x - 17) + (4x + 28) = 180°
= 9x - 17 + 4x + 28 = 180°
By adding x variables together,
13x + 11 = 180°
=> 13x = 180°-11
=> x = 169° ÷ 13
x = 13
By substituting x,
∠Q = 9 x 13 - 17
= 117 - 17
= 100°
∠Q + ∠T = 180° (angles on a straight line is 180°)
100 + ∠T = 180°
∠T = 180 - 100
∠T = 80°
Therefore the value of ∠T is 80°.

Considering the given image, we can easily spot that (B) line 2 is the line of symmetry.
What are lines of symmetry?A form or item is divided into two equal and symmetrical portions by a line of symmetry.
Because it divides the figure symmetrically and the separated portions resemble mirror images of one another, we also refer to this line as the axis of symmetry or the mirror line.
Rotational symmetry, reflection symmetry, translation symmetry, and glide reflection symmetry are some examples of symmetries.
Planar symmetry, which refers to various types of symmetry on a flat surface, is illustrated by these four different types of symmetry.

Graph a triangle ABC and perform a translation of (x + 4, y - 3) to create triangle A'B'C'.
1. Describe the transformation using words. Make sure you refer to the characteristics
and the coordinates.
2. Draw a line through points A and A' and through points B and B'. What do you
notice about the lines you drew? Do you think you would notice the same
characteristics if you drew another line through points C and C'? How do you know?
1. The translation was of 4 units right and 3 units down.
2. All the blue lines connecting the equivalent vertices will have a slope of -3/4.
What is the translation?
The translations of the triangle is given by the rule presented as follows:
(x,y) -> (x + 4, y - 3).
Hence the meaning of each of these translations is given as follows:
x -> x + 4 is a translation of four units right.y -> y - 3 is a translation of three units down.The coordinates of the original vertices are given as follows:
(0,0), (0,4), (3,0).
Then the coordinates of the translated vertices are given as follows:
(4,-3), (4,1), (7,-3).
For a linear function, the slope is given by the vertical change divided by the horizontal change.
From these translations, the changes are given as follows:
Vertical change of 3 units down, hence of -3.Horizontal change of 4 units right, hence of +4.Thus the slope of the linear function connecting the original vertices are given as follows:
m = -3/4.

Slope of the line having passing points (6,-5) and (-6,-5) is 0.
What do you mean by slope of the line?
A line's slope is defined as the ratio of the change in y coordinate to the change in x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Hence, the change in y-coordinate with regard to the change in x-coordinate is given by,
m = change in y/change in x
Given passing points :
(6,-5) and (-6,-5)
Slope of the line having passing points (x,y) and (a,b) is given by [tex]\frac{b-y}{a-x}[/tex]

If you can make payments of $450 on a 5-year loan that has an APR of 6.5%,
what is the maximum loan amount you can afford?
Answer:
To determine the maximum loan amount you can afford, you need to know the amount of your monthly payment and the annual percentage rate (APR) of the loan. The APR is the interest rate of the loan, expressed as a yearly rate. It takes into account not only the interest rate, but also any fees or other charges associated with the loan.
In this case, you know that you can make monthly payments of $450 and that the APR of the loan is 6.5%. To determine the maximum loan amount you can afford, you can use the following formula:
Maximum loan amount = (Monthly payment / (APR / 100 / 12)) * (1 - (1 + (APR / 100 / 12))^-n)
where n is the number of monthly payments. In this case, you are taking out a 5-year loan, which means you will make 60 monthly payments (5 years * 12 months/year = 60 months), so n = 60. Plugging these values into the formula, we have
Maximum loan amount = ($450 / (6.5% / 100 / 12)) * (1 - (1 + (6.5% / 100 / 12))^-60)
= ($450 / 0.00542) * (1 - (1 + 0.00542)^-60)
= $83,146.54
Therefore, the maximum loan amount you can afford is $83,146.54. This is the maximum amount you can borrow, assuming that you make monthly payments of $450 and the APR of the loan is 6.5%. You should carefully consider your ability to make these monthly payments before taking out a loan of this amount.

select the most appropriate response. in the construction of confidence intervals, if all other quantities are unchanged, a decrease in the sample size will lead to a interval.
If all other quantities are unchanged, a decrease in the sample size will lead to a wider confidence interval.
What is a sample size?
Sample size refers to the number of observations or measurements that are taken from a larger population as part of a statistical study. In statistical analysis, a sample is a subset of the population being studied, and the sample size is the number of observations or units of analysis included in the sample.
A decrease in the sample size will lead to a wider confidence interval in the construction of confidence intervals.
In statistical inference, a confidence interval is a range of values that is estimated to contain the true value of a population parameter with a certain level of confidence. The width of the confidence interval depends on several factors, including the sample size, the level of confidence, and the variability of the data.
In general, as the sample size increases, the precision of the estimate of the population parameter improves, and the width of the confidence interval decreases. Conversely, as the sample size decreases, the precision of the estimate decreases, and the width of the confidence interval increases.
Hence, if all other quantities are unchanged, a decrease in the sample size will lead to a wider confidence interval.

Question below
At one point the average price of regular unleaded gasoline was $3.65 per gallon. Assume that the standard deviation price per gallon is $0.06 per gallon and use Chebyshev's inequality to answer the following.
(a) What percentage of gasoline stations had prices within 4 standard deviations of the mean?
(b) What percentage of gasoline stations had prices within 1.5 standard deviations of the mean? What are the gasoline prices that are within 1.5 standard deviations of the mean?
(c) What is the minimum percentage of gasoline stations that had prices between $ 3.43 and $3.83 ?
Prices at 93.75% of gasoline stations were within four standard deviations of the mean. Prices at 44.44% of gas stations were within 1.5 standard deviations of the mean. The prices within 1.5 standard deviations of the mean are $3.56 to $3.74. The minimum percentage of gasoline stations with prices between $3.43 and $3.83 is 15.46%.
Chebyshev's inequality states that the proportion of data within k standard deviations of the mean is at least 1 - 1/k² for all values of k.
(a) To find the percentage of gasoline stations with prices within 4 standard deviations of the mean, we can plug k = 4 into the formula above to get 1 - 1/4² = 1 - 1/16 = 15/16 = 93.75%.
(b) To find the percentage of gasoline stations with prices within 1.5 standard deviations of the mean, we can plug k = 1.5 into the formula above to get 1 - 1/1.5² = 1 - 1/2.25 = 4/9 = 44.44%. The prices within 1.5 standard deviations of the mean are $3.65 +/- (1.5 × 0.06) = $3.65 +/- $0.09, so the prices within 1.5 standard deviations of the mean are $3.56 to $3.74.
(c) To find the minimum percentage of gasoline stations with prices between $3.43 and $3.83, we can use Chebyshev's inequality with k = ($3.83 - $3.43)/(0.06) = 4.17. Plugging this value into the formula gives us 1 - 1/k² = 1 - 1/17.3 = 15.46%, which is the minimum percentage of gasoline stations with prices between $3.43 and $3.83.
