El mayor es Novecientos mil cuatrocientos ochenta y nueve , y cuarenta mil dos
Answers
El número "Novecientos mil cuatrocientos ochenta y nueve" se representa como 900,489 en notación numérica.
Por otro lado, el número "cuarenta mil dos" se representa como 40,002.
Si estamos buscando determinar cuál de estos dos números es mayor, podemos comparar las cifras en cada posición.
Comenzando desde la izquierda, el primer dígito de 900,489 es 9, mientras que el primer dígito de 40,002 es 4.
Dado que 9 es mayor que 4, podemos concluir que 900,489 es mayor que 40,002.
En general, al comparar números, se debe observar cada posición en orden de mayor a menor importancia.
Esto significa que el primer dígito a la izquierda es el más significativo y tiene más peso en el valor total del número.
Si los dígitos en la posición más significativa son iguales, se debe pasar a la siguiente posición hasta que se encuentre una diferencia.
En este caso, dado que el primer dígito de 900,489 es mayor que el primer dígito de 40,002, no es necesario comparar los dígitos en posiciones posteriores.
Por lo tanto, podemos concluir que el número "Novecientos mil cuatrocientos ochenta y nueve" (900,489) es mayor que "cuarenta mil dos" (40,002).

Question 9 A cylindrical beaker with a base radius of 3 inches and a height of 11 Inches weighs 3.5 ounces when empty. The beaker is filled with water to one inch from the top. If one cubic Inch of water weighs 0.6 ounce, how many ounces does the beaker weigh, including the weight of the cylindrical beaker? Explain how you found your answer. Round to the nearest tenth.
Answers
The weight of the beaker, including the weight of the water, is approximately 173.1 ounces when rounded to the nearest tenth. To find the weight of the beaker when filled with water, including the weight of the cylindrical beaker itself, we need to calculate the weight of the water and add it to the weight of the empty beaker.
First, let's find the volume of the water in the beaker. The beaker is filled to one inch from the top, which means the height of the water is 11 - 1 = 10 inches.
The volume of the water can be calculated using the formula for the volume of a cylinder: \(V = \pi r^2h\), where r is the radius and h is the height.
\(V = \pi (3^2)(10) = 90\pi\) cubic inches
Next, we need to find the weight of the water. Given that one cubic inch of water weighs 0.6 ounces, we can multiply the volume of the water by 0.6 to get the weight of the water.
Weight of water = 90π x 0.6 = 54π ounces
Finally, we need to add the weight of the empty beaker, which is 3.5 ounces, to the weight of the water.
Weight of beaker with water = 54π + 3.5 ounces
To find the approximate value, we can use the value of π as 3.14.
Weight of beaker with water ≈ 54 x 3.14 + 3.5 ≈ 169.56 + 3.5 ≈ 173.06 ounces

Find the probability of 3 success for the binomial experiment with 7 trial and the success probability of 0.3. Then find the mean and standard deviation. Write the formula substitute
the values.
Answers
Answer:
\(P(x=3)=0.2269\)
Mean=2.1
Standard deviation=1.21
Step-by-step explanation:
We are given that
n=7
Probability of success, p=0.3
q=1-p=1-0.3=0.7
We have to find the probability of 3 success for the binomial experiment and find the mean and standard deviation.
Binomial distribution formula
\(P(X=x)=nC_xp^{x}q^{n-x}\)
Using the formula
\(P(x=3)=7C_3(0.3)^3(0.7)^{7-3}\)
\(P(x=3)=7C_3(0.3)^3(0.7)^{4}\)
\(P(x=3)=\frac{7!}{3!4!}(0.3)^3(0.7)^{4}\)
\(P(x=3)=\frac{7\times 6\times 5\times 4!}{3\times 2\times 1\times 4!}(0.3)^{3}(0.7)^{4}\)
Using the formula
\(nC_r=\frac{n!}{r!(n-r)!}\)
\(P(x=3)=0.2269\)
Now,
Mean, \(\mu=np=7\times 0.3=2.1\)
Standard deviation, \(\sigma=\sqrt{np(1-p)}\)
Standard deviation, \(\sigma=\sqrt{7\times 0.3\times 0.7}\)
Standard deviation, \(\sigma=1.21\)

The coordinates of point A are (-2,5). The coordinates of point B are (3,5). Which expression represents the distance, in units, between A and B?
Answers
The distance expression of the number of units between points A and B is √[(-2 - 3)^2 + (5 - 5)^2]
How to determine the expression of the distance between A and B?From the question, we have the following parameters:
The coordinates of point A are (-2,5). The coordinates of point B are (3,5).This means that
A = (-2, 5)
B = (3, 5)
The distance between the points is calculated as
Distance = √[(x2 - x1)^2 + (y2 - y1)^2]
Where
A = (x1, y1) = (-2, 5)
B = (x2, y2) = (3, 5)
Substitute the known values in the above equation
So, we have
Distance = √[(-2 - 3)^2 + (5 - 5)^2]
The question does not imply that the we simplify the above expression
So, we leave the expression unsimplified
Hence, the expression of the distance between A and B is √[(-2 - 3)^2 + (5 - 5)^2]

two angles are supplementary. If one of the angles is (8x+20)° and the other is (3x-5)°, what is the measure of both angles? choose both answers below.
Answers
ANSWER
140 degrees and 40 degrees
EXPLANATION
We have that the two angles given are supplementary angles.
Supplementary angles are angles that add up to 180 degrees.
The two angles given are:
(8x + 20) degrees and (3x - 5) degrees
This means that:
8x + 20 + 3x - 5 = 180
Collect like terms:
8x + 3x + 20 - 5 = 180
11x + 15 = 180
11x = 180 - 15 = 165
x = 165 / 11
x = 15
Therefore, the first angle is:
8(15) + 20 = 120 + 20 = 140 degrees
The second angle is:
3(15) - 5 = 45 - 5 = 40 degrees

Ahab's total change to funds is -$175, which means he spent more than he gained.
What are the funds?Ahab spent 3 tires at $50 each, which is a total of 3 x $50 = $150.
Later, he returned one tire, so he gets $50 back.
He also found a $5 bill, so he has an extra $5.
He then bought 2 jackets at $40 each, which is a total of 2 x $40 = $80.
The total amount Ahab spent is $150 + $80 = $230.
However, he also received $50 back and found $5, so his total change to funds is $50 + $5 - $230 = -$175.
Therefore, Ahab's total change to funds is -$175, which means he spent more than he gained.

Answers
The test statistic (37.96) is greater than the critical value (11.345), we can reject the null hypothesis and conclude that there is a significant relationship between admission date and birthday.
The test statistic for this test is calculated by summing the squared differences between the observed and expected frequencies in each category, divided by the expected frequency in that category. This formula is:
X² = ∑(observed - expected)² / expected
The degrees of freedom for this test are equal to the number of categories minus one (4-1=3). Using a significance level of 0.01, the critical value for this test is 11.345.
To calculate the test statistic for this sample, we first need to calculate the expected frequencies. Each category should have an expected frequency of 196/4 = 49.
Category 1: expected frequency = 49, observed frequency = 12
Category 2: expected frequency = 49, observed frequency = 22
Category 3: expected frequency = 49, observed frequency = 65
Category 4: expected frequency = 49, observed frequency = 97
Using the formula above, we can calculate the test statistic:
X² = [(12-49)²/49] + [(22-49)²/49] + [(65-49)²/49] + [(97-49)²/49]
X² = 37.96

Assuming a 365-day year (i.e., excluding leap year), in the absence of any relation, a patient's admission date is equally likely to be any one of the 365 possible days. The investigators established four different admission categories: (1) within 7 days of birthday, (2) between 8 and 30 days, inclusive, from the birthday, (3) between 31 and 90 days, inclusive, from the birthday, and (4) more than 90 days from the birthday.
