What is the bisector of the triangle?
The bisector of a triangle is a segment that divides one of its interior angles into two equal parts and continues until it reaches the side opposite that angle. In other words, the bisector of a triangle is a line that divides each interior angle of the triangle into two equal angles.
We have given,
Segment AD is an altitude of ΔABC.
If CD ≅ BD
So, AD is the middle line of the triangle
AD is also an altitude of ΔABC.
So, AD is also an internal bisector of ΔABC
So, AB ≅ AC ............{Thereom of unity of three lines}
Hence, AD is also an internal bisector of ΔABC, this statements prove that AB is congruent to AC.

Mr. Mosley ordered pizzas for the volunteers at Highland School's fundraiser event. He ordered 12 large pizzas from the Roman Rounds pizzeria. Since this was a bulk order, Roman Rounds reduced the price of each large pizza by $2. The total came to $192. Which equation can you use to find the amount of money, p, Roman Rounds normally charges for a large pizza?
Answers
Equation that we can use to find the amount of money, p, Roman Rounds normally charges for a large pizza is 12(p - 2) = 192.
Let's use p to represent the normal price of a large pizza from Roman Rounds. Since Mr. Mosley ordered 12 large pizzas and received a $2 discount on each, he paid a total of $192. We can use this information to set up the following equation:
12(p - 2) = 192
In this equation, 12 represents the number of large pizzas that were ordered, and (p - 2) represents the discounted price of each pizza. The left side of the equation gives us the total amount that Mr. Mosley paid for the pizzas. By setting this expression equal to 192, we can solve for p, the normal price of a large pizza from Roman Rounds.
To solve for p, we first distribute the 12 on the left side of the equation:
12p - 24 = 192
Next, we add 24 to both sides of the equation:
12p = 216
Finally, we divide both sides of the equation by 12:
p = 18
Therefore, the normal price of a large pizza from Roman Rounds is $18.

the weights of medium oranges packaged by an orchard are normally distributed with a mean of 14 oz and a standard deviation of 2 oz. 1 orange is randomly selected. what is the probability that this orange weighs more than 17 oz?
Answers
The probability that an orange weighs more than 17 oz is 0.1587.
The probability that an orange weighs more than 17 oz is 0.1587. This value can be calculated using the Z-score formula, which is used to calculate the probability of an event occurring. The formula is as follows:
Z = (x - μ) / σ
where x is the data point, μ is the mean, and σ is the standard deviation.
In this case, the Z-score is (17 - 14) / 2 or 1.5. We can find the probability using the Z-score table, which gives us 0.1587, the probability that an orange weighs more than 17 oz.
The Z-score formula is useful for determining the probability of an event occurring when the data follows a normal distribution. Knowing the mean and standard deviation, we can calculate the likelihood of a certain outcome occurring. In this case, the probability that an orange weighs more than 17 oz is 0.1587.

A shipping container will be used to transport several 130-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27500 kilograms. Other shipments weighing 3100 kilograms have already been loaded into the container. Which inequality can be used to determine cc, the greatest number of 130-kilogram crates that can be loaded onto the shipping container?
Answers
The inequality is c ≤ 187, where c is the number of 130-kg crates that can be added to the shipping container
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the number of 130-kg crates that can be added to the shipping container be c
The greatest weight the shipping container can hold = 27,500 kg
The weight that is already loaded = 3,100 kg
So , the total number of 130kg weights = 130c
Substituting the values in the equation , we get
27500 - 3100 ≥ 130c
130c ≤ 24,400
Divide by 130 on both sides of the equation , we get
c ≤ 187.69
So , the value of c is 187 crates

A right triangle has acute angles c and d . If c=15/8 and sin d=8/17, what are cos d and cos c?
Answers
The value of the right triangle cos d = 15/17 and cos c = 8/17.
What are trigonometric functions?Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.
Given that, the value of tan c = 15/8 and the value of sin d = 8/17.
From the trigonometric functions we can conclude that:
Opposite side to c = 15
Adjacent side to c = 8
Hypotenuse = 17
Opposite side to d = 8
Adjacent side to d = 15
The values of cos d is:
cos d = Adjacent side to d / Hypotenuse = 15/17
cos c = Adjacent side to c / Hypotenuse = 8/17
Hence the value of the right triangle cos d = 15/17 and cos c = 8/17.

Explanation:
The normal curve, aka bell curve, has mirror symmetry with the mean at the very center. Half of the data is below the mean, while the other half is above the mean.
About 68% of the data will lie below the mean in a normally distributed data set. This is known as the Empirical Rule, which states that if a data set is approximately normally distributed, then approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

if the quadrilateral is enlarged by a scale factor of 3, what will be the new perimeter?3.2 3.2 9.6 8 6.4 4.8
Answers
The new perimeter of the quadrilateral is 157.2 ft
Consider the following diagram.
We name the quadrilateral ABCD such that side AB = 12.2 ft, side BC = 16 ft, side AD = 12 ft
Let us assume that the perpendicular or height be DE = 12 ft
From figure we can observe that side AB = side CD
So, side CD = 12.2 ft
The quadrilateral is enlarged by a scale factor of 3
so, the dimensions of the new quadrilateral would be,
A'B' = 3 × AB
= 36.6 ft
So, C'D' = 36.6 ft ............(as AB = CD)
B'C' = 3 × BC
B'C' = 48 ft
And A'D' = 3 × AD
A'D' = 36 ft
We know that the perimeter of quadrilateral is the sum of all the four sides.
So, the perimeter of new quadrilateral A'B'C'D' would be,
A'B' + B'C' + C'D' + A'D'
= 36.6 + 48 + 36.6 + 36
= 157.2 ft

Using a statistical method called a confidence interval, we can estimate the range of values that the true proportion of times the die would land on the number 4 is likely to fall within, with 90% confidence.
The confidence interval calculated for this data is 0.398 to 0.562.
Since this interval includes the value of 0.5 (which would be the proportion of times a fair die would land on the number 4), By using statistical method we cannot reject the hypothesis that the die is fair.

The formula for interest is written as,
I = (PRT)/100
Divide ₹1750 into 2 parts such that if one part is lent out at 15% per annum for 2 years and the other part at 16% per annum for 3 years, the total interest is 624.
Let 'x' be the amount of lent out at 15%. Then the amount of lent out at 16% is (₹1750 - x). Then the equation is given as,
(x · 0.15 · 2) + [(1750 - x) · 0.16 · 3] = 624
Simplify the equation, then we have
(x · 0.15 · 2) + [(1750 - x) · 0.16 · 3] = 624
0.30x + 840 - 0.48x = 624
0.18x = 216
x = ₹1,200
Then the value of (₹1750 - x) is given as,
