The probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is 0.62 or 62%.
To calculate the probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip, we will use the formula: $P(\text{Child or Evening Trip}) = P(\text{Child}) + P(\text{Evening Trip}) - P(\text{Child and Evening Trip})$.We are given that there were 7 children on the morning trip and 24 adults on the evening trip.
Therefore, the number of children who were on the evening trip is 0. Hence, $P(\text{Evening Trip}) = 24/50 = 0.48$.
Similarly, the number of children who were not on the evening trip is 7, while the number of adults who were not on the evening trip is $50 - (7 + 24) = 19$. Hence, $P(\text{Child}) = 7/50 = 0.14$.
Since no child was on the evening trip, $P(\text{Child and Evening Trip}) = 0$.
Substituting these values in the formula above, we get: $P(\text{Child or Evening Trip}) = 0.14 + 0.48 - 0 = 0.62$
Therefore, the probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is 0.62 or 62%.

Trapezoid ABCD has been translated down and to the right to form trapezoid RSTU. Given that AB ll DC, Which of the following statements is true concerning trapezoid RSTU?
The true statements concerning trapezoid RSTU are:
STUT
CABRS
DRS UT
Based on the given information that Trapezoid ABCD has been translated down and to the right to form trapezoid RSTU, we can determine the relationships between the corresponding sides and angles of the two trapezoids.
Given:
AB || DC
Based on the parallel lines, we can infer the following relationships:
Corresponding sides are parallel:
RS || UT (corresponds to AB || DC)
ST || RU (corresponds to BC || DA)
Corresponding angles are congruent:
∠R ≅ ∠A
∠S ≅ ∠B
∠T ≅ ∠C
∠U ≅ ∠D
From these relationships, we can determine the following statements that are true concerning trapezoid RSTU:
STUT (corresponds to ABCD): The bases of the trapezoids are parallel, so the order of the vertices remains the same.
CABRS (corresponds to DCBA): The corresponding angles in trapezoid RSTU and trapezoid ABCD are congruent.
DRS UT (corresponds to ABDC): The order of the vertices is reversed, but the parallel sides and corresponding angles remain the same.
Therefore, the true statements concerning trapezoid RSTU are:
STUT
CABRS
DRS UT

A cylindrical tank with a radius of 12 inches and a height of 20 inches is full of water. does the tank have enough water to fill 250 spherical shaped water balloons if each of the water balloons has a radius of 2 inches? Explain plz
Answer:
yes It has
Step-by-step explanation:
v of the tank
v= [tex]\pi[/tex]r^2 h
v=3.14*144*20
v=9034
the v of each ballon :
V = 4/3 [tex]\pi[/tex]r^3
v=4/3 * 3.14 .8
v= 33.5
all the ballons v is 250 * 33.5 = 8373
9034-8373 = 661 v of the water in the tank would be left
A soccer dome shaped like a hemisphere has a volume of 450,000 cubic meters. What is the area of its floor? Use 3.14 for π in your calculations and round your answer to the nearest square meters
Answer:
3282 m^2
Step-by-step explanation:
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 22/7
r = radius
r = (450,000 x (3/2) x(1/3.14)) ^1/3
r = 45.72
Area of a semicircle = 1/2 x n x r^2
1/2 x 45.72^2 x 3.14 = 3282 m^2

Each stripe is 1/18 yards thick, and the fence post if 5/6 yards. Therefore, we have to find how many 1/18s can go into 5/6. Thus, this is a matter of division, and we do 5/6 divided by 1/18 to find how many stripes we can have.
5/6 ÷ 1/18 = 5/6 * 18 = 15
Thus, the answer is D.
4) A is 3, which means we substitute all the "a"s in the expression for 3. Thus we have:
99 - 7[tex]a^{2}[/tex]
99 - 7(3)^2
99 - 7(9)
99 - 63 = 36
Therefore, it is 36.

Step-by-step explanation:
dimensions of rectangle are (7-3),(8-3)

area of rectangle=4×5=20
area of bottom Δ=1/2×4×2=4
area of top Δ=1/2×3×3=9/2
area of right triangle=1/2 ×5×1=5/2
area of Δ HIJ=20-(4+9/2+5/2)
=20-(4+14/2)
=20-(4+7)
=9 sq. units.
or area of triangle =1/2

C. If Stephanie was short of wrapping paper, how much more did she need? If Stephanie had enough wrapping paper, how much of the ten feet was left over?
Complete question :
Stephanie has six identical gift boxes to wrap. Each box is a cube that measures 6 inches on each side. She would like to wrap them all using the same gift wrapping paper. The roll of wrapping paper she has is 30 inches wide and 10 feet long.
Answer:
Left over = 2292 in²
Step-by-step explanation:
Given that :
Gift boxes are identical ;
Each gift box is a cube with side length, s = 6 inches
Area of gift box, Surface area of a cube = 6s²
Area = 6(6²) = 6 * 36 = 216 in²
Area of one gift box = 216 in²
6 gift boxes will be : 216 in² * 6 = 1296 in²
Allowing 2 inches to cover for overlap in each box : 2 inches * 6 = 12 in²
Dimension of wrapping paper = 30 inches by 10 feets
Recall :
1 Feet = 12 inches
Hence ; dimension of wrapping paper becomes :
30 inches by (10*12) inches
30 inches by 120 inches
Area of wrapping paper = 30 * 120 = 3600 in²
Total area of paper - area of gifbox - area of overlap
(3600 - 1296 - 12) in²
= 2292 in²
Leftover = 2292 in²

9. Hallar el perímetro de la figura sombreada.
Lado del cuadrado 6 m. (Las curvas son
semicircunferencias)
M
Respuesta:
Perímetro de la parte sombreada = (6pi + 24)
Explicación paso a paso:
Encuentra el diagrama adjunto
Primero necesitamos encontrar el perímetro de los semicírculos externos que sobresalen
Diámetro del semicírculo = 1/2 de la longitud del lado del cuadrado
Diámetro del semicírculo = 1/2 × 6 m = 3 m
Perímetro de los 4 semicírculos = 4 (pi d)
Perímetro de los 4 semicírculos = 4 × 3,14 × 3
Perímetro de los 4 semicírculos exteriores = 1
2pi cm
Para la parte interior sombreada = Perímetro de todo el cuadrado - Perímetro de semicírculo (2 cuadrantes)
Perímetro del cuadrado entero = 4 (6) = 24m
Perímetro de los 2 cuadrantes = pi d
Perímetro de los 2 cuadrantes = 6pi cm
Para la parte sombreada interior, perímetro = 24-6pi
Perímetro de la parte sombreada = 12pi + 24-6pi
Perímetro de la parte sombreada = (6pi + 24) cm

Gia knows that the formula for the surface area of a cube is A = 6s2, where s is the cube's side length. She wants to find the surface area of a cube with sides of length of LaTeX: \frac{1}{4}1 4- foot. What is the surface area of this cube?
Answer:
The area of the cube is equal to [tex]0.375\ \text{foot}^2[/tex].
Step-by-step explanation:
The formula for the surface area of a cube is :
[tex]A=6s^2[/tex]
Where
s is the cube's side length
Put s = 1/4 foot
So,
[tex]A=6\times (\dfrac{1}{4})^2\\A=0.375\ \text{foot}^2[/tex]
So, the area of the cube is equal to [tex]0.375\ \text{foot}^2[/tex].

Answer:
A. x^2+3x-4
B. 6x^2-5x+1
Answer:
A: x^2+3x-4
B: 6x^2 -5x +1
Step-by-step explanation:
Alright, so for this, use the FOIL method, by multiplying the terms of each question in this order:
First
Outer
Inner
Last
So with the first question, lets do this:
(x+4)(x-1)
F: x * x = x^2
O: x * -1 = -x
I: x * 4 = 4x
L: 4 * -1 = -4
Then combine the like terms together:
x^2 + -x + 4x -4
A: x^2+3x-4
With the next one, same deal:
(2x-1)(3x-1)
F: 2x * 3x = 6x^2
O: 2x * -1 = -2x
I: 3x * -1 = -3x
L: -1 * -1 = 1
Then combine them up:
6x^2 -2x -3x +1
B: 6x^2 -5x +1
All done!
