Using proportions, it is found that you would expect to get a sum of 3 22 times.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
When two dice are rolled, there are 36 total outcomes. 2 of them, (1,2) and (2,1), result in a sum of 3, hence the proportion is given by:
p = 2/36 = 1/18.
Out of 396 tosses, the expected value is given by:
E = 1/18 x 396 = 22.

Harry's kitchen table is round and has a radius of 2 feet. What is the tabletop's diameter?
Answer:
4
Step-by-step explanation:
An object's radius is half of the object's diameter.
Solving for diameter
d = r * 2Solving for radius
r = d/2d = r * 2
= 2 * 2
= 4
The diameter of Harry's table is 4 feet.

La siguiente tabla presenta las frecuencias absolutas y relativas de las distintas caras de un dado cuando se simulan 300 lanzamientos en una página web: Si ahora se simulan 600 lanzamientos en la misma página web, Marcos cree que la frecuencia relativa de la cara con el número 6 será 0,36, porque se simula el doble de los lanzamientos originales. Por otro lado, Camila cree que la frecuencia relativa de la cara número 6 se acercará más al valor 0,166, tal como el resto de las frecuencias relativas de la tabla
La opinión correcta es la de Camila que argumenta que la frecuencia relativa de la cara con el #6 será un valor cercano a 0,166.
Qué es la frecuencia relativa?La frecuencia relativa es un término matemático que se utiliza en la estadística para referirse al número de veces que un evento se repite durante un experimento.
Por otra parte, es necesario aclara que la frecuencia relativa no se modifica en gran medida si se aumenta el número de veces de una prueba, debido a que la probabilidad de ocurrencia de este evento va a ser la misma.
De acuerdo a lo anterior, Camila tiene razón debido a que considera que el valor de la frecuencia relativa no se modifica en gran medida entre 300 o 600 lanzamientos de los dados.
Nota: Esta pregunta está incompleta porque no está la tabla. No obstante, la puedo responder basado en mi conocimiento previo.

Answer:
x = 7.5, x = -5
Step-by-step explanation:
1. Plug a(2), b(-5), and c(-75) into the qudratic formula:
[tex]x_{1,2} =\frac{-(-5)+-\sqrt{(-5)^{2}-4(2)(-75) } }{2(2)}[/tex]
2. Find the square:
[tex]x_{1,2} =\frac{-(-5)+-\sqrt{25-4(2)(-75) } }{2(2)}[/tex]
[tex]x_{1,2} =\frac{-(-5)+-\sqrt{25+600} }{2(2)}[/tex]
[tex]x_{1,2} =\frac{-(-5)+-25 }{4}[/tex]
3. Separate the solutions:
[tex]x_{1} = \frac{-(-5)+25}{4} , x_{2} =\frac{-(-5)-25}{4}[/tex]
4. Solve for both:
[tex]x_{1} =\frac{5+25}{4} \\\\x_{1} =\frac{30}{4} \\\\x_{1} =\frac{15}{2}\\\\x_{1} =7.5[/tex]
--------------------
[tex]x_{2} =\frac{5-25}{4} \\\\x_{2} =\frac{-20}{4} \\\\x_{2} =-5[/tex]
In conclusion, the solutions are x = 7.5 and -5.

Landon Wallin is an auto mechanic who wishes to start his own business. He will need $4100 to purchase tools and equipment. Landon decides to finance the purchase with a 60-month fixed installment loan with an APR of 6%.
a) Determine Landon's finance charge.
b) Determine Landon's monthly payment.
Answer:
a.$1230
b.$20.50
Step-by-step explanation:
Assuming Landon only makes the minimum payments for the sixty months this is how you would find it
Multiply loan by percentage over the five years: 4100 x .3 = 1230
Then divide that amount by months paid: 1230/60= 20.5

One tank can hold, on average, 108.1 gallons of water. A half tank will hold 54.05 gallons of water.
Step-by-step explanation:
432.4 galloons in total in 4 tanks
432.4 : 4
? : 1
432.4/4=108.1, so 108.1 gallons in each tank
Half of 108.1 is 54.05, so half a tank would have 54.05 gallons.

What is the inverse of `y = 5x + 7
Show Steps!
Answer:
[tex]\sf y' = \dfrac{x-7}{5}[/tex]
Explanation:
⇒ y = 5x + 7
⇒ 5x + 7 = y
⇒ 5x = y - 7
⇒ x = (y-7)/5
replace x with y
⇒ y' = (x-7)/5
Take this and solve for x
5x=y-7x=y-7/5Interchange y and x
y=x-7/5So
The inverse is
[tex]\\ \rm\dashrightarrow y^{-1}(x)=\dfrac{x-7}{5}[/tex]
Which statement is true?
We will see that the fourth statement:
"-0.3*|3 + 8x| = 0.9 has no solutions."
Is the true statement.
Which statement is true?Here we need to see which statement regarding absolute value equations is true.
Here you can see that the fourth statement is:
-0.3*|3 + 8x| = 0.9 has no solutions.
Now, if you look at the left side of the above equation, the left side will always be negative, while the right side is positive, then the equation can't have a solution.
There is no value of x that makes that equation true, so it is true that the given equation has no solutions. This is the correct statement.

What type of triangle is defined by the following set of side lengths
11, 9 , 7
Acute
Obtuse
Right
Not a triangle
Answer:
ACUTE TRIANGLE
Step-by-step explanation:
If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.
Therefore, the triangle with sides 11, 9, and 7 is an acute triangle since 9² + 7² is greater than 11²
