In a large population, 53 % of the people have been vaccinated. If 5 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?
The probability the at least of the people selected from 5 is vaccinated is 0.997.
What is meant by the binomial distribution?The binomial distribution is a statistical probability distribution that summarizes the likelihood of a value taking one of two independent values under the specific set of assumptions or assumptions.
The likelihood that at least one person has been vaccinated = 1 - the likelihood that nobody has been vaccinated. In a large population, the probability of a randomly selected person NOT being vaccinated is 1 - 0.53 = 0.47.Because the five randomly chosen people are independent, the probability that they're all unvaccinated is (0.47)⁵,
The probability that at least one among them 5 has been vaccinated is;
= 1 - (0.47)⁵
= 0.997
Therefore, the probability that at least one of the five people chosen is vaccinated is 0.997.

Solve for the system of equations.
Y=2x+3
2y-x=12
For the system of equations y = 2 x + 3 and 2 y - x = 12, the solution will be x = 2 and y = 7.
We are given the system of equations:
y = 2 x + 3 … (1)
2 y - x = 12 …. (2)
We need to solve it to find the values of x and y.
Putting the value of y from equation (1) in equation (2), we get that:
2 y - x = 12
2 (2 x + 3) - x = 12
Multiplying the brackets, we get that:
4 x + 6 - x = 12
3 x + 6 = 12
Subtract 6 from both the sides, we get that:
3 x + 6 - 6 = 12 - 6
3 x = 6
Divide both sides by 3. we get that:
3 x / 3 = 6 / 3
x = 2
y = 2 x + 3
y = 2 (2) + 3
y = 4 + 3
y = 7
Therefore, we get that, for the system of equations y = 2 x + 3 and 2 y - x = 12, the solution will be x = 2 and y = 7.

The length of a rectangle parking area is three times the width.The perimeter is 280 yd.Find the length and width of the parking are.
Answer:
length = 105 yd
width = 35 yd
Step-by-step explanation:
Let L = length and W = width.
L = 3W
perimeter = 2(L + W)
280 =2(L + W)
L = 3W
We have a system of 2 equations. Let's use the substitution method to solve it. Substitute 3W for L in the first equation.
280 = 2(3W + W)
140 = 4W
W = 35
L = 3W = 3(35) = 105
length = 105 yd
width = 35 yd

Draw a rotation of segment CD 189 degrees around point D.
Rotation of a point through 189° about the origin When a point C(h, k) is rotated through 180° in either an anticlockwise or clockwise direction about the origin O, it takes the new position D(-h, -k).
The rotation formula will give us the precise location of a point after a finite degree of rotation. The rotation formula is determined by the type of rotation applied to the point in relation to the origin. A geometric two-dimensional shape can undergo four major types of transformation.
The rotation formula describes how a point rotates with respect to the origin. The rotation formula is used to determine the position of a point after it has been rotated. A rotation is a circular motion around a specific axis or point of rotation. In general, rotation can be done in two ways: clockwise and anti-clockwise or counter-clockwise.

The true statement about the angles of the triangle OPQ is the third statement that is m∠P < m∠O < m∠Q.
It is given that:-
In triangle OPQ,
PQ = 19
QO = 11
OP = 20
We have to find which one of the six statements given in the question is correct.
We know that, in a triangle, if one side of the triangle is longer than the other side, then the angle opposite to the longer side will be larger than the angle opposite the shorter side.
Hence,
In triangle OPQ,
Angle opposite to side OP = ∠Q
Angle opposite to side PQ = ∠O
Angle opposite to side QO = ∠P
As,
QO < PQ < OP , Hence,

Find the angle in degrees between the two planes
x − 10y − 8z = 11
and
2x + 5y + 8z = 1.
(Round your answer to two decimal places.)
The angle in degrees between the two planes is approximately 159.460°.
What is the angle between two planes?
The equation of the plane, whose form is a · x + b · y + c · z = d is equivalent to this vectorial form (a, b, c) • (x, y, z) = d, where (a, b, c) is the vector of coefficients. The angle between the two planes:
θ = cos⁻¹ [[(a₁, b₁, c₁) • (a₂, b₂, c₂)] / [||(a₁, b₁, c₁)|| · ||(a₁, b₁, c₁)||]]
If we know that (a₁, b₁, c₁) = (1, - 10, - 8) and (a₂, b₂, c₂) = (2, 5, 8), then the angle between the two planes is:
θ = cos⁻¹ [[(1, - 10, - 8) • (2, 5, 8)] / [√165 · √93]]
θ = cos⁻¹ [(-2 - 50 - 64) / √15345]
θ = cos⁻¹ (- 116 / √15345)
θ ≈ 159.460°

Using translation concepts, the vertices of the triangle after the rotation are given as follows:
G'(2,-2), E'(5,-4), F'(5,-1).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
The rule for a 90º counterclockwise rotation around the origin is:
(x,y) -> (-y,x).
Hence the vertices should be given by:
G': (-2,-2) -> (2,-2).E': (-4,-5) -> (5,-4). (here you committed a mistake, should be one left and one up to where you positioned).F': (-1,-5) -> (5,-1). (here you committed a mistake).The correct translation is graphed at the end of the question. You are doing a good job, just there was two small mistakes on the rule :).

the 2nd and 5th terms of a gp are 1/18 and 4/243 respectively. Find
Answer:
Step-by-step explanation:
The third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.
We are given that:
2nd term of geometric progression = 1 / 18
5th term = 4 / 243
Now, we can also write it as:
2nd term = a r ( where r is the common ratio and a is the initial term.)
a r = 1 / 18
5th term = a r⁴
a r⁴ = 4 / 243
Now divide 5th term by 2nd term, we get that:
a r⁴ / a r = ( 4 / 243 ) / ( 1 / 18 )
r³ = 72 / 243
r³ = 8 / 27
r = ∛ (8 / 27)
r = 2 / 3
3rd term = a r²
a r² = a r × r
= 1 / 18 × 2 / 3
3rd term = 1 / 27
Therefore, the third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.
