The measure of angle R in ΔSRT which is drawn inside the circle is 77.5°.

Circle is a two-dimensional shape that is defined as the set of all points that are equidistant from a central point. It is often represented as a round shape with a curved boundary.

Since SR is a diameter of the circle, it follows that angle STR is a right angle (90°). Therefore, we can find the measure of angle SRT using the following equation:

∠SRT + ∠STR = 180°

(2x-23°) + 90° = 180°

2x + 67° = 180°

2x = 180° - 67°

2x = 113°

x = 56.5°

∠TRS = 5x-97°

∠TRS = 5(56.5°)-97°

∠TRS = 192.5°

Finally, we can find the measure of angle SRT:

∠SRT = 180° - ∠STR - ∠TRS

∠SRT = 180° - 90° - 192.5°

∠SRT = -102.5°

Therefore, to find the measure of angle R, we need to add 180° to angle SRT:

∠R = ∠SRT + 180°

∠R = -102.5° + 180°

∠R = 77.5°

Graphs are used to show the relationship between two variables (usually x and y). The values of x when \(f(x) = 0\) are 2 and 8

The graph of y = f(x) is given

To get the values of x when \(f(x) = 0\), we simply consider where the line of the graph crosses the x-axis.

The graph crosses the x-axis at:

Answer:

D : reflection over the y-axis followed by a translation to the right one unit

Answer:

The number is 4/9

Step-by-step explanation:

3(6*(4/9))=3*(2+(2/3))=8

Answer

Option D is the pair of functions which is not a pair of inverse function.

Explanation

First of, the inverse of a function is a function that reverses the actions of the function. That is, for the inverse function, if we are given f(x), we would be able to obtain x.

The step to finding a function's inverse is to write y instead of f(x). We then rewrite by replacing the y by x and then make y the subject of formula, the y which is a subject of formula now, represents the inverse function, f⁻¹(x).

For each of them, we can get the other one from it.

f(x) = (x + 1)/6

y = (x + 1)/6

x = (y + 1)/6

Cross multiply

6x = y + 1

y = 6x - 1

g(x) = 6x - 1

f(x) = (x - 4)/19

y = (x - 4)/19

x = (y - 4)/19

19x = y - 4

y = 19x + 4

g(x) = 19x + 4

f(x) = x⁵

y = x⁵

x = y⁵

y = 5√x

g(x) = 5√x

Only option D doesn't give the inverse of the other function.

Answer:

x = 3

x = (-1)/2

x = 13/4

Step-by-step explanation:

Solve for x:

(2 x)/3 + 15 = 17

Put each term in (2 x)/3 + 15 over the common denominator 3: (2 x)/3 + 15 = (2 x)/3 + 45/3:

(2 x)/3 + 45/3 = 17

(2 x)/3 + 45/3 = (2 x + 45)/3:

1/3 (2 x + 45) = 17

Multiply both sides of (2 x + 45)/3 = 17 by 3:

(3 (2 x + 45))/3 = 3×17

(3 (2 x + 45))/3 = 3/3×(2 x + 45) = 2 x + 45:

2 x + 45 = 3×17

3×17 = 51:

2 x + 45 = 51

Subtract 45 from both sides:

2 x + (45 - 45) = 51 - 45

45 - 45 = 0:

2 x = 51 - 45

51 - 45 = 6:

2 x = 6

Divide both sides of 2 x = 6 by 2:

(2 x)/2 = 6/2

2/2 = 1:

x = 6/2

The gcd of 6 and 2 is 2, so 6/2 = (2×3)/(2×1) = 2/2×3 = 3:

Answer:  x = 3

______________________________________________________

Solve for x:

3 x - x + 8 = 7

Grouping like terms, 3 x - x + 8 = (3 x - x) + 8:

(3 x - x) + 8 = 7

3 x - x = 2 x:

2 x + 8 = 7

Subtract 8 from both sides:

2 x + (8 - 8) = 7 - 8

8 - 8 = 0:

2 x = 7 - 8

7 - 8 = -1:

2 x = -1

Divide both sides of 2 x = -1 by 2:

(2 x)/2 = (-1)/2

2/2 = 1:

Answer: x = (-1)/2

_______________________________________

Solve for x:

4 (2 x - 6) = 2

Divide both sides of 4 (2 x - 6) = 2 by 4:

(4 (2 x - 6))/4 = 2/4

4/4 = 1:

2 x - 6 = 2/4

The gcd of 2 and 4 is 2, so 2/4 = (2×1)/(2×2) = 2/2×1/2 = 1/2:

2 x - 6 = 1/2

Add 6 to both sides:

2 x + (6 - 6) = 1/2 + 6

6 - 6 = 0:

2 x = 1/2 + 6

Put 1/2 + 6 over the common denominator 2. 1/2 + 6 = 1/2 + (2×6)/2:

2 x = 1/2 + (2×6)/2

2×6 = 12:

2 x = 1/2 + 12/2

1/2 + 12/2 = (1 + 12)/2:

2 x = (1 + 12)/2

1 + 12 = 13:

2 x = 13/2

Divide both sides by 2:

x = (13/2)/2

2×2 = 4:

Answer: x = 13/4

The number that is non-irrational is 5.73, because it can be written as a quotient of two integers.

A rational number is a number that can be written as a quotient of two integer numbers, while an irrational number can't be written like that.

Also, the square root of a non perfect square is also irrational.

Here the options are:

5.73, ,√73, √40

Notice that neither of the square roots of non perfect square numbers, so these are irrational numbers.

In other hand, if we see the first one:

5.73

We can rewrite this as:

5.73 = 573/100

Therefore, the sample proportion is 0.66, or 66% (rounded to two decimal places).

The sample proportion is the proportion of the sample that believes the United States will be less important in the world 30 years from now. To calculate this, we divide the number of people in the sample who believe this by the total sample size:
Sample proportion = Number of people who believe the United States will be less important in the world 30 years from now / Total sample size
In this case, the number of people who believe this is 132, and the total sample size is 200. So we have:
Sample proportion = 132 / 200
Simplifying this fraction, we get:
Sample proportion = 0.66

Therefore, the sample proportion is 0.66, or 66% (rounded to two decimal places). This means that in the sample of 200 U.S. adults, 66% of them believe that the United States will be less important in the world 30 years from now. It's worth noting that this is slightly higher than the population proportion of 60%, but this difference could be due to random sampling variability. To draw more precise conclusions, we would need to conduct a hypothesis test and calculate a confidence interval.

y=2x+7 is equation passing through the point that is parallel to the given equation.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The equation of line passing through a point is

y-y₁=m(x-x₁)

The given line is y=2x+4

Compare the line y=2x+4 to slope intercept form we get m=2.

The equation of line passing through (-4, -1)

y-(-1)=2(x-(-4))

y+1=2(x+4)

y+1=2x+8

y=2x+7

Hence y=2x+7 is the parallel line to the equation y=2x+4.

Step-by-step explanation:

(34x - 1 ) + 45 = 180 [co-interior angles add up to 180 degrees]

Given:

The figure of a right triangle.

To find:

The measure of x.

Solution:

According to the altitude on hypotenuse theorem, the length of the altitude is the geometric mean of segments of the hypotenuse.

Let "h" be the height  of the altitude and it divides the hypotenuse if two pieces of lengths "a" and "b", then

\(h=\sqrt{ab}\)

In the given figure, 14 is the height  of the altitude and it divides the hypotenuse if two pieces of lengths 24 and x. So, by using the altitude on hypotenuse theorem, we get

\(14=\sqrt{24x}\)

Taking square on both sides.

\(196=24x\)

\(\dfrac{196}{24}=x\)

\(\dfrac{49}{6}=x\)

Therefore, the value of x is \(\dfrac{49}{6}\) units and its approximate value is 8.167 units.

When describing quantitative data, an outlier a. is a data point that does not fit the main pattern of the data.

In statistics, an outlier is a data point that dramatically deviates from the overall pattern or trend of the data. It is an observation that, in a population-based random sampling, deviates unusually from the other values. Outliers can skew the overall analysis or interpretation of the data since they are either greater or lower than the bulk of the data points. As a data point that does not fit the predominant pattern of the data, an outlier is precisely defined as such.

Option (b) is not always accurate since outliers may have reasonable values, despite being rare. Option (c) is not always accurate, though, as data input mistakes may not always be the cause of outliers. Because not all probable outliers can be identified using the 1.5 times the interquartile range (IQR), which is a popular approach, option (d) is inaccurate.

Interval estimation, in measurements, is the assessment of a boundary — for instance, the mean (normal) — of a populace by processing a stretch, or scope of values, inside which the boundary is probably going to be found. Spans are normally picked to such an extent that the boundary falls inside with a 95 or 99 percent likelihood, called the certainty coefficient. Subsequently, the spans are called confidence intervals; the endpoints of such a span are called upper and lower certainty limits.

The interval containing a population parameter is laid out by working out that measurement from values estimated on an irregular example taken from the populace and by applying the information (got from the probability theory) of the constancy with which the properties of an example address those of the whole populace.

Answer:  D) reflection across y = -x

Explanation:

When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).

When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is \((x,y) \to (-y,-x)\)

So if we apply that rule to point A(3,1) then it becomes A ' (-1, -3).

Similarly, B(1,5) moves to B ' (-5, -1)

Finally, C(6,9) becomes C ' (-9, -6)
