2. No, the information conveyed through the triangles is not enough to conclude that the triangles are congruent.
3. Yes, the two triangles given are congruent by the HL Congruence theorem.
Which congruence theorems render the triangles congruent?1. By observation: the two Triangles represented in 1. share a side and also, the two corresponding sides are congruent; it can be concluded that the two triangles are congruent.
2. Although two sides are said to be congruent in the triangles; it cannot be concluded that the triangles are congruent neither by HL nor SSS congruence theorem.
3. The two Triangles share the diagonal which is the hypothenuse of both triangles.
Additionally, one of the other side lengths of the triangles are congruent; Therefore, the triangles are congruent by the HL congruence theorem.

The correct option is B. Out of every 5 trials, the desired outcome will occur approximately 2 times.
Explain the term experimental probability?The number of times an event happened during the experiment as a percentage of all the times the experiment was run is known as that of the experimental probability of that event occurring.The ratio between the number of favorable events and the total number of conceivable outcomes is known as the theoretical probability.For the stated question -

what can we conclude about the endogeneity of an explanatory variable if the ols and 2sls estimates are significantly different? assume that the instrument used was exogenous.
Answers
Note that assuming that the instrument used was exogenous, one can conclude about the endogeneity of an explanatory variable if the OLS and 2SLS estimates are significantly different: "The explanatory variable is endogenous and therefore 2SLS should be considered." (Option C)
What is 2SLS?Two-stage least squares (2SLS) regression analysis is a statistical approach used in structural equation analysis. The OLS approach has been extended using this methodology. It is employed when the error terms of the dependent variable are associated with the independent variables.
The ordinary least squares (OLS) approach is a linear regression methodology used to estimate a model's unknown parameters. The strategy is based on reducing the sum of squared residuals between the expected and actual values.
2SLS is utilized as an alternate strategy when we encounter endogeneity Problems in OLS. Endogeneity arises when the explanatory variable correlates with the error word. Then we utilize 2SLS, which employs an instrumental variable. The outcome will be different because if there is endogeneity in the model, OLS will produce biased results.

If the m<2 = 58° and the m<13 = 111°, find the measures of angles 1, 5, 8, 14, 18.
Note: x || m and z || y
Answers
The value of angle 1 is 122°.
The value of angle 5 is 58°
The angle of angle 8 is 58°
The angle of angle 14 is 122°
The angle 18 is 58°
How to calculate the angles?It should be noted that this information deals with angles. It should be noted that the value of angle on a straight line is 180°.
In this situation, the value of angle 1 will be:
= 180° - 58°
= 122°
Also it should be noted that vertically opposite angles are equal. Therefore, angle 5 will be 58°.
In this situation, it should also be noted that alternate angles are the same. Hence, Thai gives the value of the angles for angles 8, 14 and 18.

Name one segment from polygon ABCDEF and one segment from polygon A'B'C'D'E'F' that are parallel.
Answers
Step-by-step explanation:
in a dilation all the angles stay the same. only the lengths of lines (like sides or heights) change - and all with the same scale factor (which makes the original and the dilated result similar objects).
angle EDC = 117°.
therefore angle E'D'C' = 117°.
AB = 1.8 in
A'B' = 4.5 in
the scale factor r is
r = 4.5 / 1.8 = 2.5
every segment of A'B'C'D'E'F' is parallel to its original counterpart in ABCDEF.

Answers
Answer:B) -2x + 3y = 12 represents the graph.The y-intercept is 4, and the line intercepts the x-axis at -6. Therefore, the slope of the line is 4/6=2/3.

Leo argues that the measure of an exterior angle of a triangle is
equal to the sum of the measures of the two remote interior angles of
the triangle. He uses the diagram shown in his argument.
Xº
Leo writes the steps listed.
Step 1.r+x=180, since the sum of the measures of supplementary
angles is 180°
Step 2. p+q+r=180, since the sum of the measures of the angles
of any triangle is 180°
Which equations follow from step 1 and step 2 that Leo could use to
complete his argument?
r+x=p+q+r
r+x-r=p+q+r-r
x=p+q
p+q+r=180
bp+q+r-r=180-r
p+q=180-r
x+r=p+q+r
x+r-r=p+q+r+r
x=p+q+2r
(r+x) + (p+q+r)=180+180
2r+x+p+q=360
Answers
Answer:
Step-by-step explanation: It looks like Leo is trying to prove that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles of the triangle. From the equations given, it seems that Leo is using the fact that the sum of the measures of supplementary angles is 180 degrees, and the sum of the measures of the angles of any triangle is 180 degrees, to try to prove his statement. Some equations that Leo could use to complete his argument might include:
x = p + q, which follows from the equation r + x = 180 and the substitution of p + q + r = 180
p + q = 180 - r, which follows from the equation p + q + r = 180 and the substitution of r + x = 180
x = p + q + 2r, which follows from the equation x + r = p + q + r and the substitution of r + x = 180
It's not clear from the information given whether these equations are sufficient to prove Leo's statement, as we don't have any information about the values of p, q, r, or x. However, these equations might be a good starting point for Leo to continue his argument.

the diameter of a circle is 16. by what number must the radius be decreased in order to decrease the area of the circle by $48\pi$?
Answers
To decrease the area of the circle by $48\pi$, we need to decrease the radius by a factor of $\sqrt{48\pi}$.
Since the original radius of the circle was 8, the radius must be decreased to
$\frac{8}{\sqrt{48\pi}} = \frac{8}{\sqrt{48}\sqrt{\pi}} = \frac{8}{\sqrt{48}} \approx \frac{8}{6.9282} \approx 1.1547$.Therefore, to decrease the area of the circle by $48\pi$, the radius must be decreased by a factor of about 1.1547.
This means that the radius must be decreased by a number that is about 1.1547 times smaller than the original radius of 8, or by about $8 \times (1 - 1.1547) = -0.6158$.

Answers
To measure the length of a line segment AB, place the zero marking of the ruler along the beginning of the line and measure its length.
A line segment has two definite endpoints in a line, and the line segment is fixed, which is the distance between two fixed points. The length can be measured by metric units such as centimeters, and millimeters.
A line segment with two endpoints A and B and is denoted by the bar symbol (—).
Using Ruler and Compass:
There are some markings on the ruler beginning from zero as shown in the figure. these markings divide the ruler into equal parts.
Each part is equal to a length of 1 cm and these units are measured in centimeters and are further subdivided into 10 parts and each sub-part is equivalent to 1 millimeter.
To measure a line segment AB, place the zero marking of the ruler along the beginning of the line and measure its length accordingly.

Comparing both given functions, we can state that: B. Function 1 has the greater rate of change; the slope is 2.
What is the Rate of Change/Slope of a Function?Another name for the rate of change of a function is the slope. It is calculated using the formula:
Slope / rate of change = change in y / change in x.
If the equation of a linear function is given in slope-intercept form as y = mx + b, the rate of change or the slope is represented by "m".
Given the first function as an equation, y = 2x - 6, the slope of this function is represented as 2. This means, the rate of change is m = 2.
To find the rate of change of function 2, use two points from the table, (1, -4) and (2, -5):
Rate of change / slope (m) = (-5 - (-4)) / (2 - 1) = -1/1
m = -1.
The slope value of 2 is greater than the slope value of -1, therefore, we can conclude that: B. Function 1 has the greater rate of change; the slope is 2.

In a deck of playing cards has 52 cards of which 12 are face cards, The odds are 33 / 3315 or 0.01 that the top 3 are face cards.
The total number of cards was 52, and there were 12 face cards.

The first attempt had a probability of 12/52,
the second attempt had a probability of 11/51,
