Which of the pairs of angles are vertical angles and thus congruent? ∠A and ∠G ∠A and ∠B ∠C and ∠F ∠D and ∠H
Answer:
∠A and ∠G is the pair of vertical angles.
Step-by-step explanation:
From the figure attached,
Two lines 'm' and 'n' are two parallel lines. These lines intersect a horizontal line 'l'.
Since, "Pair of opposite angles formed at the point of intersection are the vertical angles and equal in measure."
Therefore, Opposite angles ∠A ≅ ∠G, ∠B ≅ ∠H, ∠C ≅ ∠E and ∠D ∠F are the vertical angles.
From the given options,
∠A and ∠G is the pair representing the pair of vertical angles and thus congruent.
Answer:
∠A and ∠G

The graph shows the total number of participants in a town's recreation program at the end of every year since the year 2000. The line of best fit for the data is given by the equation =13+50, where y is the total number of participants x years after the beginning of the year 2000.
Which statement correctly interprets the slope of the line of best fit?
A. The rate of change is 1 new participant every 13 years.
B. The rate of change is 13 new participants every 13 years.
C. The rate of change is 13 new participants every year.
D. The rate of change is 50 new participants every year.
Answer:
B
Step-by-step explanation:
Answer:
The rate of change is 13 new participants every year.
Step-by-step explanation:
y=13x+50
This is in the form y = mx+b where m is the slope and b is the y intercept
x is the number of years so for every year increase we gain 13 new participants

The experiment proceeded as normal, with the experimental group hearing about the potential presence of a gun as the confederates left the study and the control group not hearing about the gun. Unfortunately, word spread around campus about a man with a gun who stole a laptop during a study. Unknown to the study researchers, many potential participants participated in the research anyway, and kept an eye out for a gun, knowing that they might be asked about it. The researchers found that those in the experimental group did not differ from those in the control group about the likelihood of a gun. That is, the mean score that a gun was present during the second interview was similar for the experimental group (M = 67%, SD = 12.4%) and the control group (M = 63%, SD = 11.16%).

No Threat
Answer:
The answer is "The threat to internal validity is mortality".
Step-by-step explanation:
It signifies that while in terms of your study, persons were "morning." It usually signifies when people leave the studies. There will be only likely if indeed the experiment lasts a long period that it'll be a substantial danger to validity and reliability because the chance for drops increases. Eight content validity risks are history, maturity, instrument, test, choice, average regress, human engagement, and mortality.

Answer: Choice 1
3(MC) = SC
=====================================================
Explanation:
The three medians intersect at the centroid, which is point M in this case. The intersecting medians subdivide themselves in the ratio 2:1
This means that SM is twice as long as MC. We can say SM = 2MC
Then by the segment addition postulate, we know that:
SC = SM + MC
SC = 2MC + MC
SC = 3MC
3(MC) = SC
So having three copies of MC glued together will form segment SC.
The same idea applies for the other medians also (EK = 3EM and RL = 3ML).
Three of the sides will require fencing and the fourth wall already exists.
If the farmer has 180 feet of fencing, what are the dimensions of the region with the largest area?
Answer:kind of hard try 3x-x+2=4
Step-by-step explanation:
The dimensions of the region with the largest area is length=90 feet and width=45 feet.
Given that, three of the sides will require fencing and the fourth wall already exists.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Let the length of a wall be l and the width of a wall be w.
So, l+2w=180
⇒ l=180-2w
Area of a rectangle = Length×width
A(w)= (180-2w)×w
= 180w-2w²
The value of 'w' for which the derivate of the area function is zero will yield the maximum area:
A(w)=180w-2w²
⇒ A'(w)=180-4w
⇒ 180-4w=0
⇒ 4w=180
⇒ w=45 feet
So, l=180-2w =90 feet
Therefore, the dimensions of the region with the largest area is length=90 feet and width=45 feet.

Find mCFD

O 276°
O 307°
O 53°
9514 1404 393
Answer:
307°
Step-by-step explanation:
The measure of arc CFD is the measure of the whole circle, less the measure of arc CD. The measure of arc CD is the difference between the measures of arc CE and DE. Arc CE has the same measure as arc BF, so we have ...
arc CFD = 360° -(arc BF -arc ED)
arc CFD = 360° -132° +79°
arc CFD = 307°
_____
Arcs BF and CE are of equal measure because their central angles are vertical angles, hence congruent.
