Here the conjecture we can made is :

The sum of interior angles i.e. ∠A and ∠B is equal to the exterior angle at C.

The exterior angle of any triangle is defined as the angle which is at the outside boundaries of that triangle. whereas, the interior angle is defined as the angle which is inside the triangle. In the other words if the triangle has the point within the angle it is in the interior of the angle , but if the point is outside then is it said to be in the exterior of the angle for that triangle.

In mathematics, the two angles are called as adjacent angles if they have a common vertex or we can say they are angle of a common vertex in the triangle.

we can define the adjacent angle as the angles which have common side and common vertex and they don't overlap.

According to the exterior angle property, if a side of a triangle is made, then the exterior angle formed is always equals to the sum of  two interior angles opposite to each other in the triangle.

Thus on the basis of exterior angle property we can make the conjecture that, "the measure of an exterior angle is equal to the sum of measures of its nonadjacent interior angles".

Answer: d=90 degrees

e=69 degrees

f=111 degrees

Step-by-step explanation:

69+f=180 ==> a straight line is 180 degrees and is called a straight angle. The angles that make up the straight line add up to 180 degrees.

69-69+f=180-69

f=180-69

f=111 degrees

e+f=180 ==> a straight line is 180 degrees and is called a straight angle. The angles that make up the straight line add up to 180 degrees.

e+111=180

e+111-111=180-111

e=180-111

e=69 degrees

d+90=180 ==> if there is a tiny box between an angle, that means that the angle is a right angle which measures 90 degrees.

d-90+90=180-90

d=180-90

d=90 degrees

An indicator of how much a group of numbers vary or are dispersed is the standard deviation. [1] When the standard deviation is low, the values are more likely to fall within a narrow range, also known as the expected value, whereas when the standard deviation is high, the values tend to be closer to the mean.

It would take the test administrator 48 seconds to allow for the performance of the task

So, if we want 97.5 percent, we must look it up in our z table. So I need to find the z score that is closest to.975, which is 1.96.

The 97.5th percentile point of the standard normal distribution is a quantity often used in probability and statistics for statistical computations. This figure is around 1.96, which means that 95% of the area under a normal curve is within 1.96 standard deviations of the mean.

As a result, the z score for the 97.5th percentile would be multiplied by the class standard deviation. As a result, we obtain;

1.96*6 = 11.76

The weight of the baby increased by a 20%

We know that the initial weight of the baby is 20 pounds, so that will be our 100%, and we can write:

20lb = 100%

Then the weight is 24 lb, so that will represent another percentage X, we can write:

24lb = X

We can solve this for X, taking the quotient between the relations:

(24lb/20lb)  = X/100%

(24lb/20lb)*100% = X = 120%

At 5/3s of an hour is when the cost of both tubing companies are the same.

This is when the price of both companies both hit $33.33

Step-by-step explanation:

25 + 5x = 30 + 2x

move variables by subtracting

25 + 3x = 30

move constants by subtracting  

30 - 25 = 5

5 = 3x

x = 5/3

Missing term i.e., the second term of the sequence is 5.

As the series is in an arithmetic sequence, so we have an equation

[tex]a_{n}[/tex] = a +(n-1)d

Where a = first number of the series

           n = number of term

           d= common difference

As we know the 3rd term of the sequence, so by this we can find the common difference.

So we have,

9 = 1 +(3-1)d

8=2d

d=4

common difference = 4

Now we have to find the 2nd term or the missing term of the sequence, so we have

[tex]a_{2}[/tex] = 1 +(2-1)4

   = 1+ 1×4

The total number of band members and dancers in the halftime show in all rows were 276.

A row is an arrangement of things in a straight line next to each other.

if there are n rows and each row has m members then total number of members = m* n

2) y=−6

Step-by-step explanation:

Let's solve the equation step by step.

1) 2xy - x = 3

(2)(2)y - 2 = 3

4y - 2 = 3

4y−2=3

Step 1: Add 2 to both sides.

4y−2+2=3+2

4y=5

Step 2: Divide both sides by 4.

4y/4 = 5/4

y=5/4

2) 2y + xy = 6

2y−3y=6

Step 1: Simplify both sides of the equation.

2y−3y=6

2y+−3y=6

(2y+−3y)=6(Combine Like Terms)

−y=6

−y=6

The transformation of the given function g(x) = ¹/₂|x + 4| - 3 using the format h(x) = a|bx + c| + d, gives;

a = ¹/₂

b = -1

c = 6

d = 3

We are given the function;

g(x) = ¹/₂|x + 4| - 3

Now, we are told that the function is first translated by 6 units upwards, and so this means a transformation of;

g(x) + 6 = ¹/₂|x + 4| - 3 + 6

g'(x) = ¹/₂|x + 4| + 3

Now, we are told that it now undergoes a transformation of 2 units to the right, this gives;

g"(x) =  ¹/₂|x + 4 + 2| + 3

g"(x) = ¹/₂|x + 6| + 3

Finally, after undergoing a transformation of reflection in the y-axis, we have; h(x) = ¹/₂|-x + 6| + 3

Step-by-step explanation:

The sum of the given finite series is 25

The summation notation means that we have to add the terms of the given series with n moves from the lower limit to the upper limit.

The given series is:

      [tex]\sum\limits^5_{n=1} {(2n-1)}[/tex]

In this series, the lower limit is n = 1 while the upper limit is n=5.

n = 1  ⇒ 2n - 1 =  2(1) -1 = 1

n = 2  ⇒ 2n - 1 = 2(2) -1 = 3

n = 3  ⇒ 2n - 1 = 2(3) -1 = 5

n = 4  ⇒ 2n - 1 = 2(4) -1 = 7

n = 5  ⇒ 2n - 1 = 2(5) -1 = 9

Hence,

[tex]\sum\limits^5_{n=1} {(2n-1)}=1+3+5+7+9[/tex]

We can evaluate the sum of the series directly, or by using the sum formula as follow:

S(n) = n/2 [a(1) + a(n)]

Substitute n = 5, a(1) =1, and a(n) = 9:
