Using the coordinates of the vertices of a polygon (-3, 1), (-3, 3), (-1, 5), (2, 4), and (2, 1) the perimeter of the polygon is 16.0 units
How to find the perimeter of the polygonThe perimeter is calculated by summing the sides
The length of line in an ordered pair is calculated using the formula
d = √{(x₂ - x₁)² + (y₂ - y₁)²}
where
d = distance between the points
x₂ and x₁ = points in x coordinates
y₂ and y₁ = points in y coordinates
(-3, 1) and (-3, 3) =√{(-3 - -3)² + (3 - 1)²} = 2
(-3, 3) and (-1, 5) = √{(-1 - -3)² + (5 - 3)²} = 2√2
(-1, 5) and (2, 4) = √{(2 - -1)² + (4 - 5)²} = √10
(2, 4) and (2, 1) = √{(2 - 2)² + (1 - 4)²} = 3
(2, 1) and (-3, 1) = √{(-3 - 2)² + (1 - 1)²} = 5
The perimeter = 2 + 2√2 + √10 + 3 + 5
The perimeter = 15.9907
The perimeter = 16.0 units

Find the area of the shaded region. Round to the nearest tenth. All polygons are regular.
Check the picture below.
let's take a looksie at that, notice, if we split the circle into 6 even pieces, we end up with six 60° angles at the center, namely six equilateral triangles as you see there.
now, if we run a dashed line as you see from a corner to the other to make the flatter triangle which is shaded, we end up cutting the equilateral triangle into two equal halves, each with 30° and 30° angles, because the dashed line intercepts the green line at 90°.
well, the flatter triangle from corner to corner, is spanning over two equilateral triangles, if it's owning half of one, it must be also owning half of the other. What the dickens does that mean? well, it means the area of the flatter triangle that's shaded, is really the same area as a "whole" of one of those equilateral triangles.
so hmmm we have three of those flatter triangles shaded hmm, so let's simply get the area of three of those equilateral triangles and sum them up.

In a raffle, 1,500 tickets are sold for $3 each. One ticket will be randomly selected and the winner will receive a laptop computer valued at $1000. What is the expected value for a person that buys one ticket?
e(x)=-2.33
how do you find that answer ?
The solution to probability problem is the expected value for a person that buys one ticket is -$2.32
What is probability?Probability is a measure of the likelihood or chance that a specific event will occur, expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.
According to the given information:
To find the expected value, you need to multiply each possible outcome by its probability and then add them together.
In this case, there are two possible outcomes: either the person wins the laptop computer (with a probability 1/1500), or they don't win anything (with a probability 1499/1500).
So, the expected value can be calculated as:
E(x) = (1/1500)($1000) + (1499/1500)(-$3)
E(x) = $0.67 - $2.99
E(x) = -$2.32
So the expected value for a person that buys one ticket is -$2.32.

A surveyor makes the measures indicated in Fig. 19-71. For the figure, angle A = 34o and the Hypotenuse c = 159 ft. Note the angles are named with Capital Letters A, B, and C and the names or the sides opposite the angles are named with small letter
All parts of the triangle should be solved The parts of the triangle to include in the Problem Solution are: (1) degrees of all 3 angles A, B and C, (2) lengths of the two legs a, b , rounded to the nearest whole number, (3) length of the hypotenuse and (4) the area of the triangle with the proper units. That is 7 answers total.
The side lengths of the triangle are 89 ft, 132 ft and 159 ft
The angles of the triangle are 34 degrees, 56 degrees and 90 degreesThe area of the triangle is 5874 square unitsThe sides of the triangleThe given parameters are
Angle, A = 34 degrees
Hypotenuse = 159 ft
The length BC is calculated as
sin(A) = BC/Hypotenuse
So, we have
BC = Hypotenuse * sin(A)
This gives
BC = 159 * sin(34 degrees)
Evaluate
BC = 89 ft
The length AC is calculated as
cos(A) = AC/Hypotenuse
So, we have
AC = Hypotenuse * cos(A)
This gives
AC = 159 * cos(34 degrees)
Evaluate
AC = 132 ft
The angles for the triangleHere, we have
Angle, A = 34 degrees
Because the triangle is a right triangle, we have
Angle, C = 90 degrees
The sum of angles in a triangle is 180
So, we have
Angle B = 180 - 90 - 34
Angle B = 56
The area of the triangleThis is calculated as
Area = 0.5 * BC * AC
So, we have
Area = 0.5 * 89 * 132
Evaluate
Area = 5874
Hence, the area is 5874 square units

If a polynomial f\mathopen{}\mathclose{\left(x\right)}f(x) has a remainder of 22 when divided by x-6x−6, what is f\mathopen{}\mathclose{\left(6\right)}f(6)?\
f\mathopen{}\mathclose{\left(6\right)}f(6) = (6-6)(something) + 22 = 0(something) + 22 = 22 which has a remainder of 22 when divided by x-6x-6. f\mathopen{}\mathclose{\left(6\right)}f(6) = \boxed{22}.
What is the remainder theorem?The remainder theorem states that when a polynomial is divided by a linear term, the remainder equals the value of the polynomial at the root of the linear term. This theorem may be used to determine the roots of a polynomial by dividing it by a linear term and solving for the remainder. For instance, when the polynomial x3+x2-5x+6 is divided by (x2), the result is identical to the polynomial's value at x=2. After finding the remainder, we may determine that the polynomial's root is 2, which we can do by solving for the remainder. This theorem may also be used to discover the roots of higher degree polynomials by combining linear terms.
How to solve?
f\mathopen{}\mathclose{\left(x\right)}f(x) can be written as (x-6)(something) + 22.
f\mathopen{}\mathclose{\left(6\right)}f(6) = (6-6)(something) + 22 = 0(something) + 22 = 22.
Therefore, f\mathopen{}\mathclose{\left(6\right)}f(6) = \boxed{22}.

10 Find the value of 2x+y for the simultaneous equations.
3x + 5y = 48
2x-y=19
y=3
x=11
hence answer 25
3x+5y=48
2x-y=19
eliminate x to find y
(3x+5y=48)2
(2x-y=19)3
(6x + 10y. = 96)
- minus direct
(6x - 3y. = 57)
=
13y = 39
Note: (10y -(-3y)=13y)
divide by 13 to remain with y
y =3
substitute to any equation to get x lets pick second one
2x-(3)=19
2x-3=19
2x=19+3
2x/2=22/2. (to remain with x value)
x=11
therefore 2x+ y results to 2(11) +3=25
Answer:
2x + y = 25
Step-by-step explanation:
Given equations:
[tex]\begin{cases} 3x + 5y = 48\\\;\;2x-y=19\end{cases}[/tex]
Rearrange the second equation to isolate y:
[tex]\implies 2x-y=19[/tex]
[tex]\implies 2x-19=y[/tex]
Substitute the found expression for y into the first equation and solve for x:
[tex]\implies 3x+5y=48[/tex]
[tex]\implies 3x+5(2x-19)=48[/tex]
[tex]\implies 3x+10x-95=48[/tex]
[tex]\implies 13x=143[/tex]
[tex]\implies x=11[/tex]
Substitute the found value of x into the equation for y and solve for y:
[tex]\implies y=2x-19[/tex]
[tex]\implies y=2(11)-19[/tex]
[tex]\implies y=22-19[/tex]
[tex]\implies y=3[/tex]
Therefore, the solution of the given system of equations is:
x = 11, y = 3To find the value of 2x + y, substitute the found values of x and y into the expression and solve:
[tex]\begin{aligned}\implies 2x+y&=2(11)+3\\&=22+3\\&=25\end{aligned}[/tex]

If a publisher of nontechnical books takes great pains to ensure that its books are free of typographical errors the probability of any given page containing at least one such error is 0.005 and errors are independent of the page-to-page. What is the probability that one of its 400-page novels will contain exactly one page with errors? At most three pages with errors?
Part A: Probability that one of 400-page novels will have exactly one error-free page is 24.06%.
Part B.) No more than three pages contain errors: 40.06%.
Explain the term binomial distribution?The possibility that a value would take one among two independent values given a particular combination of factors or assumptions is summarized by the statistical distribution known as the binomial distribution.The given data in the question-
X has a binomial distribution that includes,400 pages make up the novel's page count.Error probability p = 0.005Probability of error-free page q = 01 - 0.005 = 0.995The following is the probability mass function (PMF) for X:
P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ
Part A.) One of 400-page novels will have exactly one error-free page.
P(x = 1) = ⁿCₓ . pˣ . qⁿ⁻ˣ
n = 400, x = 1
P(x = 1) = ¹⁰⁰C₁ . (0.005)¹ . (0.995)¹⁰⁰ ⁻ ¹
P(x = 1) = 0.2706
Thus, probability that one of 400-page novels will have exactly one error-free page is 24.06%.
Part B.) No more than three pages contain errors.
P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
P(x = 0) = ¹⁰⁰C₀ . (0.005)⁰ . (0.995)¹⁰⁰ ⁻ ⁰
P(x = 0) = 0.01346
P(x = 1) = ¹⁰⁰C₁ . (0.005)¹ . (0.995)¹⁰⁰ ⁻ ¹
P(x = 1) = 0.0270
P(x = 2) = ¹⁰⁰C₂ . (0.005)² . (0.995)¹⁰⁰ ⁻ ²
P(x = 2) = 0.00068
P(x = 3) = ¹⁰⁰C₃ . (0.005)³ . (0.995)¹⁰⁰ ⁻ ³
P(x = 3) = 0.0000027
Thus, P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
P(x ≤ 3) = 0.01346 + 0.00068 + 0.00068 + 0.0000027
P(x ≤ 3) = 0.4060021
Consequently, the likelihood of at maximum three pages having typographical errors is 40.06%.
