A movie theater has 13 new release movie posters. How many ways can the manager choose 7
posters for a promotion?
Answer:
1716
Step-by-step explanation:
I'm pretty sure
The manager can choose a group of 7 posters for a promotion in 1716 ways.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in a total of
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]
A movie theater has 13 new release movie posters
the manager choose a group of 7 for posters.
When we choose 7 posters, the order does not matter.
So we use a combination
We need to find 7 from 13 new release movie posters.
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.\\\\^13C_7 = \dfrac{13!}{7! \times (13-7)!} ways.\\\\^13C_7 = \dfrac{13!}{7! \times6!} ways.\\\\^13C_7 = 1716[/tex]
The manager can choose a group of 7 posters for a promotion in 1716 ways.

Heyaa!! Im Pinky!! And Im Here To Inform You That Your Answer Is...
Step-by-step explanation:
!!!! A. 3/8 !!!!
My calculations:

Adam borrowed $5,600 from the bank. The bank charges 4.2% simple interest each year.
Which equation represents the amount of money in dollars, x, Adam will owe in one year, if no payments
are made?
Answer:
$235.2
Step-by-step explanation:
Given data
Principal= $5,600
Rate= 4.2%
Time= 1 year
The expression for the simple interest is given as
SI= PRT/100
substitute
SI= 5600*4.2*1/100
SI= 23520/100
SI=$235.2
Hence after 1 year he will pay $235.2
Kari lost 2.88 kilograms after two weeks of exercise. One kilogram is equal to approximately 2.2 pounds. Which measurement is closest to the number of pounds that Kari lost? Group of answer choices
Answer:
Amount of weight Kari lost in pound = 6.34 pound (Approx.)
Step-by-step explanation:
Given;
Amount of weight Kari lost in kilogram = 2.88 kilograms
Given scale;
1 kilogram = 2.2 pound
Find:
Amount of weight Kari lost in pound
Computation;
Amount of weight Kari lost in pound = Amount of weight Kari lost in kilogram x 2.2 pound
Amount of weight Kari lost in pound = 2.88 x 2.2 pound
Amount of weight Kari lost in pound = 6.336
Amount of weight Kari lost in pound = 6.34 pound (Approx.)

c = hypotenuse
4² + 5² = 25 is not equal to the square of 6 which is 36
2² + 3² = 10 . 10 is not equal to the square of 4 which is 16
10² + 20³ = 500. 500 is not equal to the square of 30 which is 900
30² + 40² = 2500. this is equal to the square of 50
What is the volume of the rectangular prism - i ready. 1/3 ft some of. The answers 1 1/9 feet3- 10 ft3 - 2/9 ft3 - 3 1/3 ft3
Answer:
[tex]3\frac{1}{3}\ ft^3[/tex]
Step-by-step explanation:
A rectangular prism is a polyhedron with six rectangular faces. The volume of a prism is given by:
Volume = width * height * length
From the diagram, the rectangular prism is made up of cubes. Each cube is has a size of 1/3 ft by 1/3 ft.
The height of the prism is made up of 5 cubes. Height = 5 * 1/3 = 5/3 ft.
The length of the prism is made up of 3 cubes. length = 3 * 1/3 = 1 ft.
The width of the prism is made up of 2 cubes. Width = 2 * 1/3 = 2/3 ft.
The volume of the prism = width * height * length = 2/3 * 5/3 * 1 = 10/9 ft³ = [tex]3\frac{1}{3}\ ft^3[/tex]
Answer:
it is 3 1/3 good day
Step-by-step explanation:
El espesor de un borde de un componente de una aeronave está distribuido de manera uniforme entre 0.05 y 1.05 milimetros.Obtenga la función de distribución acumulada del espesor del borde.Calcule la proporción de bordes cuyo espesor es mayor que 1.02 milimetros.Qué espesor estEa excedido por el 90% de los bordes.Calcule la media y la varianza del espesor.
Answer:
a) [tex]F(x)\begin{cases} & 0\text{ if } x \leq 0.05 \\ \\ &\dfrac{x - 0.05}{1.05 - 0.05} = x - 0.05 \text{ if } 0.05 \leq x \leq 1.05 \\ \\ & 1 \text{ if } x \geq 1.05 \end{cases}[/tex]
b) 0.03
c) 0.15
d) La media es 0.55
La varianza es 8.[tex]\overline 3[/tex]
Step-by-step explanation:
La variación del espesor del componente de la aeronave = 0.05 a 1.05
El pdf de la variable 'X' se da de la siguiente manera;
[tex]f(x) = \dfrac{1}{1.05 - 0.05} = 1[/tex] por 0.05 < x < 1.05
a)
[tex]F(x)\begin{cases} & 0\text{ si } x \leq 0.05 \\ \\ &\dfrac{x - 0.05}{1.05 - 0.05} = x - 0.05 \text{ si } 0.05 \leq x \leq 1.05 \\ \\ & 1 \text{ si } x \geq 1.05 \end{cases}[/tex]
b) Para la proporción de los bordes que con un espesor superior a 1.02 milímetros, obtenemos;
P(X > 1.02) = 1 - F(1.02) = 1 - (1.02 - 0.05) = 0.03
P(X > 1.02) = 0.03
La proporción de bordes que tienen un espesor mayor que 1.02 = 0.03
c) El espesor, 'x', excedido en el 90% de los bordes, se encuentra de la siguiente manera;
P(X > x) = 1 - F(x)
∴ 90/100 = 0.9 = 1 - F(x) = 1 - (x - 0.05)
x - 0.05 = 1 - 0.9 = 0.1
x = 0.1 + 0.05 = 0.15
∴ El espesor excedido en el 90% de los bordes, x = 0.15
d) Para una variable aleatoria uniforme continua, a ≤ x ≤ b, tenemos;
[tex]El \ significado, \mu = E(X) = \dfrac{(a + b)}{2}[/tex]
[tex]La \ varianza, \sigma^2 = V(X) = \dfrac{(b - a)^2}{12}[/tex]
Para la distribución de espesor de borde dada, tenemos;
0.05 < x < 1.05
[tex]\therefore El \ significado, \mu = E(X) = \dfrac{(0.05 + 1.05)}{2} = 0.55[/tex]
El significado E(X) = 0.55
[tex]La \ varianza, \sigma^2 = V(X) = \dfrac{(1.05 - 0.05)^2}{12} = 1/12 = 8.\overline 3[/tex]
La varianza, V(X) = 8.[tex]\overline 3[/tex]
