7. A mailer for posters is a triangular prism as shown. Find the surface area of the mailer. (Example 3) 4.7 in. 18 in. 4.7 in. M.lohn Sininh 1234 Anysvert Anytown, 4 in. 5 in.
Answer:
279.2 squared inches
Step-by-step explanation:
first find the base of the triangular prism which is 18*5=90.
then multiply 18*4.7 to get 84.6 then multiply that by 2 to get 169.2
then find the area of the triangles which is 4*5= 20 then add it all up which is equal to 279.2 ( 90 + 20) + 169.2= 279.2

¿CÓMO ALCANZÓ EL HOMBRE EL CONCEPTO DE INFINITO?
Trabajar con el infinito es un asunto complicado. Las paradojas de Zenón alertaron por primera vez a los filósofos occidentales sobre esto en 450 a. C. cuando argumentó que un corredor rápido como Aquiles tiene un número infinito de lugares para alcanzar durante la persecución de un corredor más lento. Desde entonces, ha habido una lucha por entender cómo usar la noción de infinito de una manera coherente. Este artículo se refiere al importante y controvertido papel que juegan los conceptos de infinito y el infinito en las disciplinas de la filosofía, las ciencias físicas y las matemáticas.
Los filósofos quieren saber si hay más de un concepto coherente de infinito; qué entidades y propiedades son infinitamente grandes, infinitamente pequeñas, infinitamente divisibles e infinitamente numerosas; y qué argumentos pueden justificar las respuestas de una forma u otra.
Aquí hay algunos ejemplos de estas cuatro formas diferentes de ser infinito. La densidad de la materia en el centro de un agujero negro es infinitamente grande. Un electrón es infinitamente pequeño. Una hora es infinitamente divisible. Los números enteros son infinitamente numerosos. Estas cuatro afirmaciones están ordenadas de mayor a menor controversia, aunque las cuatro han sido cuestionadas en la literatura filosófica.
Este artículo también explora una variedad de otras preguntas sobre el infinito. ¿Es el infinito algo indefinido e incompleto, o es completo y definido? ¿Qué quiso decir Tomás de Aquino cuando dijo que Dios es infinitamente poderoso? ¿Estaba en lo cierto Gauss, que fue uno de los más grandes matemáticos de todos los tiempos, cuando hizo la controvertida observación de que las teorías científicas involucran infinitos simplemente como idealizaciones y simplemente para facilitar la aplicación de esas teorías, cuando en realidad todas las entidades físicamente reales son ¿finito? ¿Cómo cambió la invención de la teoría de conjuntos el significado del término "infinito"? ¿Qué quiso decir Cantor cuando dijo que algunos infinitos son más pequeños que otros? Quine dijo que los primeros tres tamaños de los infinitos de Cantor son los únicos en los que tenemos motivos para creer. Los platónicos matemáticos no están de acuerdo con Quine. ¿Quién tiene razón? Veremos que existen profundas conexiones entre todas estas cuestiones.

Answer:
x=3.5
Step-by-step explanation:
12x=4(x+2)+20
multiply the parentheses by 4
12x = 4x+8 +20
add 20 to 8
12x = 4x +28
subtract 4x on both sides
8x = 28
divide both sides by 8
x=3.5
Answer:
9.[tex] \:\:x = 3. 5[/tex]
10. y = 8x + 12
Step-by-step explanation:
9.
12x = 4(x + 2) + 20
12x = 4x + 8 + 20
12x - 4x = 28
8x = 28
x = 28/8
x = 7/2

A correlation coefficient is a(n): a. independent variable that is used in a correlational study. b. numerical indicator of the strength and direction of a relationship between two factors. c. index of the practical rather than the statistical significance of research findings. d. numerical indicator of the statistical significance of the findings in a particular research study.
Answer:
b. numerical indicator of the strength and direction of a relationship between two factors.
Step-by-step explanation:
Correlation coefficient:
The correlation coefficient between two variables is how closely they are related.
For example, in vectors with high correlation coefficient, they are similar, while with low coefficient, they are significantly different. So the correct answer is given by option b.

Evaluate the expression 120n + 160,500 when n = 32
Answer:
164,340
Step-by-step explanation:
If n=32 and it has no sign next to it then it means you must multiply so 120 x 32 = 3840 and 3840 + 160,500 = 164,340.
Hope this helps and have a wonderful day :)
Answer:
164,340
Step-by-step explanation:
equation:
⇒ 120n + 160,500
n = 32
substitute 32 for n in the equation:
⇒ (120)(32) + 160,500
solve:
⇒ (120)(32) + 160,500
⇒ 3,840 + 160,500
⇒ 164,340

A grocery store counts the number of customers who arrive during an hour. The average over a year is 10 customers per hour. Assume the arrival of customers follows a Poisson distribution. (It usually does.) Find the probability that at least one customer arrives in a particular one minute period. Round your answer to 3 decimals. Find the probability that at least two customers arrive in a particular 4 minute period. Round your answer to four decimals.
Answer:
0.1535 = 15.35% probability that at least one customer arrives in a particular one minute period.
0.1443 = 14.43% probability that at least two customers arrive in a particular 4 minute period.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
Find the probability that at least one customer arrives in a particular one minute period.
The average is of 10 customers per hour(60 minutes), so for this case, [tex]\mu = \frac{10}{60} = \frac{1}{6}[/tex]
This is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-\frac{1}{6}}*(\frac{1}{6})^{0}}{(0)!} = 0.8465[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8465 = 0.1535[/tex]
0.1535 = 15.35% probability that at least one customer arrives in a particular one minute period.
Probability that at least two customers arrive in a particular 4 minute period.
The average is of 10 customers per hour(60 minutes), so for this case, [tex]\mu = \frac{10*4}{60} = \frac{4}{6} = \frac{2}{3}[/tex]
This probability is:
[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]
In which
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
So
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-\frac{2}{3}}*(\frac{2}{3})^{0}}{(0)!} = 0.5134[/tex]
[tex]P(X = 1) = \frac{e^{-\frac{2}{3}}*(\frac{2}{3})^{1}}{(1)!} = 0.3423[/tex]
[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.5134 + 0.3423 = 0.8557[/tex]
[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.8557 = 0.1443[/tex]
0.1443 = 14.43% probability that at least two customers arrive in a particular 4 minute period.

1. If line m | line n and angle6 measures 55 degrees , what is the measure of angle1
Answer:
m<1 = 125°
Step-by-step explanation:
Given that line m is parallel to line n, therefore:
m<2 = m<6 (corresponding angles theorem)
m<2 = 55°
Therefore,
m<1 = 180° - m<2 (linear pair)
m<1 = 180° - 55°
m<1 = 125°

PLEASE HELP (5th grade math) giving away Brainliest
Answer:
y = [tex]\frac{3}{1}[/tex]+1First, we should know what the slope-intercept formula is.
Y = MX + B
Where M is your slope, and B is your y intercept.
Let's do the easiest part first, finding our y-intercept. The y-intercept is where the the line intersects the y-axis. In this case, y = 1, because it intersects at (0, 1).
Now we have:
y = mx + 1
Next, we need to calculate the slope, or rise over run. M is presented as a fraction. The numerator is your rise (how high or low it goes), and the denomenator is your run (how far to the right or left it goes).
If it goes LEFT, the number is negative, if it goes RIGHT it is positive.
Also, pretty points are areas in which the line hits an exact coordinate. Using these points is easiest if you want to find the slope of the line.
We can see that the line hits a pretty point every time it goes one coordinate (box) to the right, and up three boxes. What this means it is rises three 3 points, and runs to the right, 1. This is shown as [tex]\frac{3}{1}[/tex]
So let's add that to the equation!
y = [tex]\frac{3}{1}[/tex]+1
please help me its hard!
Answer:
600
Step-by-step explanation:
Consider ABC and ACD as two triangles. And AC as a base to both of them
so,
AC = AO + OC
= 15 + 25
= 40
Now the area of ABC =
[tex]\frac{1}{2}\times AC\times OB\\= \frac{1}{2}\times 40 \times 10\\= 200[/tex]
In the same way, the area of ACD =
[tex]\frac{1}{2}\times AC\times OD\\= \frac{1}{2}\times 40 \times 20\\= 400[/tex]
Both added together 400 + 200 = 600

Step-by-step explanation:
An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorption into the skin. Eight locations on the forearm were designated for ointment application. The new ointment was applied to six locations, and a control was applied to the other two. How many different choices were there for the six locations to apply the new ointment
Answer:
There were 28 different choices for the six locations to apply the new ointment
Step-by-step explanation:
The order in which the location are chosen is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Two events, A and B are independent, if:
[tex]P(A \cap B) = P(A)P(B)[/tex]
How many different choices were there for the six locations to apply the new ointment?
Six locations from a set of 8. So
[tex]C_{8,6} = \frac{8!}{6!2!} = 28[/tex]
There were 28 different choices for the six locations to apply the new ointment
