Find the coordinates of the centroid of the triangle with the given vertices. (Lesson 5-2)
A(1,7), B(4,2), C(7,7)
The triangle with vertices located at A(1 , 7), B(4 , 2), and C(7 , 7) has its centroid located at (4 , 16/3).
The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.
To get the centroid of a triangle, use the formula given by:
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
where C is the centroid of the triangle located at (x , y)
x1, x2, and x3 are the x-coordinate of the vertices of the triangle
y1, y2, and y3 are the y-coordinate of the vertices of the triangle
Let Point 1(x1 , y1) = A(1 , 7)
Point 2(x2 , y2) = B(4 , 2)
Point 3(x3 , y3) = C(7 , 7)
Plug in the values in the formula.
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
C(x ,y) = [(1 +4 + 7)/3 , (7 + 2 + 7)/3]
C(x ,y) = (12/3 , 16/3)
C(x ,y) = (4 , 16/3)

According to Mrs. Wendell 's histogram (shown below), 25% of her cows weigh between 800 and 1199 pounds.
What exactly is a histogram, and why is it useful?A popular charting tool is a histogram. On an interval scale, it is used to describe either discrete or continuous data. It is widely used to show the key properties of distribution of the data in an easy-to-understand fashion.
How do you interpret a histogram?Examine the histogram to see if it shows a normal distribution. Once you've plotted all of the frequencies here on the histogram, it will take on a shape. If the shape resembles a bell curve, it indicates that perhaps the frequencies are evenly distributed. A peak would appear on the histogram.
Briefing:Ms. Wendell sells 25% of her her cows. While purchasing a cow, it is important to remember that weight is an important factor. While there may be some exceptions, the majority of cows sold in the United States weigh between 800 and 1200 pounds.
So, if your farm falls within this range, it would be wise to consider buying a cow from Mrs. Wendell .
Additionally, based on these numbers alone, it would make sense for you to purchase one or more cattle from Mrs. Wendell.
Therefore,
according to Mrs. Wendell 's histogram (shown below), 25% of her cows weigh between 800 and 1199 pounds.

of the 505050 u.s. states, 444 have names that start with the letter \text{w}wstart text, w, end text. what percentage of u.s. states have names that start with the letter \text{w}wstart text, w, end text?
The required percentage of US states having their names starting with W is 8 %. This is gained by using the concept of percentage.
What do you mean by percentage?
The percentage is usually denoted by the symbol '%'. It is defined as the quantity or ratio which is being expressed in a fraction of 100, where 100 is the denominator.
Calculation of the percentage of US states having their names starting with W
Given:
Total states in US = 50
US states that start with the letter W = 4
Fraction in favour of the names of states starting with the letter W is given by = 4 / 50
Therefore the percentage of US states having their names starting with the letter W is equal to the fraction in favour * 100 %
= 4 / 50 * 100 %
= 4 * 2 %
= 8 %
Hence, the percentage of US states having their first letter as W is 8 %.

A chip is randomly drawn from the bag. Find probability.
P (yellow)
The probability, P (yellow), that a yellow chip is drawn from the bag is 4/19.
Probability is a term used in mathematics to determine the likelihood that an incident will take place as in this case is the likelihood that a yellow chip is drawn from the bag.
Probability can be given by the formula:
probability= Number of favorable outcomes ÷ Total number of possible outcomes
Hence, in this problem, the formula for probability will be:
P (yellow) = Number of yellow chips / Total number of chips in the bag
The total number of chips in the bag will be equal to the sum of the chips of all colors.
That is, total number of chips = 3 blue chips + 7 red chips + 4 yellow chips + 5 green chips
Total number of chips = 19 chips
So the probability of a yellow chip being drawn out will be:
P ( yellow) = 4/19

a piece of wire 100 inches long is cut into two pieces and each bent into the shape of a square. if the sum of the areas of the two squares is 400 in2, find the length of each piece of wire.
For the given wire, the length of each piece of wire will be 76inch and 24 inch and quadratic equation will be x² - 100x + 1800 = 0
What is a quadratic equation?An algebraic equation of a second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.
Given,
Length of wire = 100 inches
Sum of the areas of two squares = 400 inch²
let length of one wire - x
the length of other wire will be - 100-x
Now, the area of the square = Side²
⇒ (x/4)² + ((100 - x)/4)² = 400
⇒ (1/4)² (x² + 10000 + x² - 2(100)(x)) = 400
⇒ 10000 + 2x² + - 200x = 400 × 16
⇒ 2x² - 200x = 6400 - 10000
⇒ 2x² - 200x = - 3600
⇒ x² - 100x + 1800 = 0
⇒On solving for the value of x, we have x= 76 and 24
Now,
76/4 = 19,
24/4 = 6
So, we have the length of each wire as 76inch and 24inch

What is the distance between (-3, 6) and (5, 2)
The distance between (-3, 6) and (5, 2) is 4√5 by using the distance formula.
Distance between two points in x y plane by distance formula is:
= √{(x₁ - x₂)² + (y₁ - y₂)²}
Substituting the values of the points:
= √{( -3 - 5 )² + ( 6 - 2 )²}
Solving it further:
= √{( -8 )² + ( 4 )²}
= √{ 64 + 16 }
= √80
= √(2× 2 × 2 × 2 ×5 )
= 2×2× √5

Stocks ms. patel invested a total of $825 in two stocks. at the time of her investment, one share of stock a was valued at $12.41 and a share of stock b was valued at $8.62. she purchased a total of 79 shares. select the system of equations that model the situation. solve by using substitution.
Ms Patel purchased 38 shares of stock a and 41 shares of stock b
Total amount invested in the two stocks = $825
Value of stock a = $12.41
Value of stock b = $8.62
Let the number of shares of stock a be x
Let the number of shares of stock b be y
Therefore, forming the equation we get:
x + y = 79------(1)
12.41x + 8.62y = 825
1241x + 862y = 82500 ------(2)
Multiplying equation (1) by 862 we get,
862x + 862y = 68098------(3)
Equating equations (2) and (3) we get
379x = 14402
x = 38
Putting x = 38 in (1) we get
y = 41
Hence, she purchased 38 shares of stock a and 41 shares of stock b

Find the length of a rectangle with a perimeter of 32 meters and a width of 5 meters
Answer:
Length is 11 meters
Step-by-step explanation:
Formula we use,
→ P = 2(l + w)
Then the length of rectangle will be,
→ 32 = 2(L + 5)
→ 2L + 10 = 32
→ 2L = 32 - 10
→ L = 22/2
→ [ L = 11 m ]
Hence, the length is 11 meters.
let r be a relation defined on set s where s is the set of all people in usa, and x r y means that x and y can communicate using the same spoken language. the relation r on s is reflexive.
Based on the information illustrated,
the relation r on s is reflexive. Therefore, it's true.
How to explain the information?If every component of a set X is related to one another, then a relation R over that set is said to be reflexive.
If (a, a) R for all A, that is, if every element of A is R-related to itself, or if aRa for every a A, then R is set to be reflexive.
In the example question, S is the set of all Park students, and R is a relation over S.
When a relationship is described as xRy, it signifies that x and y have the same biological mother.
This relation is obviously a reflexive relation. xRx means x and x has the same biological mother. In this case, the relation satisfies the requirement for all aR (a,a) R.
