You will get brainiest if you include a detailed explanation. Thank You!
Answers
Answer:
252
Step-by-step explanation:
The second and third smallest factors must add to 5. The only possibility is that these factors are 2 and 3.
The second and third largest factors must add to \(462-N\). These factors are \(N/2\) and \(N/3\).
\(462-N=\frac{N}{2}+\frac{N}{3} \\ \\ 462-N=\frac{5N}{6} \\ \\ 462=\frac{11N}{6} \\ \\ N=252\)

A car dealership pays a wholesale price of $14,000 to purchase a car. They sell the car for
$16,100. What is the percent mark-up for the car?
Answers
Answer:
115% or 15%
Step-by-step explanation:
14000=100%
16100=X%
14000/100=140
16100/140=115
so 115% or 15%
The percentage markup for the car is 15%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
The wholesale price of the car = $14,000
The selling price of the car = $16,100
Now,
The markup price.
= 16,100 - 14000
= $2,100
Now,
The percentage markup.
= 2,100/14000 x 100
= 15%
Thus,
The percentage markup is 15%.

a) The mean of the data-set is of 2.
b) The range of the data-set is of 4 units, which is of around 4.3 MADs.
How to obtain the mean of a data-set?The mean of a data-set is obtained as the sum of all observations in the data-set divided by the number of observations in the data-set, which is also called the cardinality of the data-set.
The dot plot shows how often each observation appears in the data-set, hence the mean of the data-set is obtained as follows:
Mean = (1 x 0 + 5 x 1 + 3 x 2 + 5 x 3 + 1 x 4)/(1 + 5 + 3 + 5 + 1)
Mean = 2.
The range is the difference between the largest observation and the smallest, hence:
4 - 0 = 4.
4/0.93 = 4.3 MADs.

Find the center and radius of the circle with a diameter that has endpoints (-6,10)
and (2,3)Enter the center as an ordered pair, : Enter the radius as a decimal correct to three decimal places :
Answers
Step-by-step explanation:
the center of the circle is the midpoint of the diameter.
and the radius is the distance of the midpoint to either endpoint (or simply half of the distance between the diameter endpoints).
the midpoint between points A and B
(xm, ym) = ((xa + xb)/2, (ya + yb)/2)
in our case the midpoint (center of the circle) is
((-6 + 2)/2, (10 + 3)/2) = (-4/2, 13/2) = (-2, 6.5)
about the radius
diameter² = (-6 - 2)² + (10 - 3)² = (-8)² + 7² = 64 + 49 =
= 113
diameter = sqrt(113) = 10.63014581...
radius = diameter / 2 = 5.315072906... ≈ 5.315
Nate has 8 x (12 x 34 x 56) jelly beans. Walt has (12 x 34 x 56)
jelly beans. How many times more jelly beans does Nate have
than Walt?
Answers
Answer:
Nate has 8 times more jelly beans than Walt.
Step-by-step explanation:
Nate's quantity:
8 x (12 x 34 x 56)
Walt's quantity:
(12 x 34 x 56)
To find the ratio, we can divide Nate's quantity by Walt's quantity:
Ratio = Nate's quantity / Walt's quantity
Ratio = (8 x (12 x 34 x 56)) / (12 x 34 x 56)
Simplifying the expression:
Ratio = 8
Therefore, Nate has 8 times more jelly beans than Walt.

1. Los estudiantes de primer grado de la IE Miguel Grau son 184, si la relación entre los que usan anteojos y los que no usan es de 3/5. ¿Cuántos estudiantes usan anteojos?
Answers
Answer:
69 estudiantes.
Step-by-step explanation:
Sabemos que el número total de estudiantes en primer grado es 184.
También sabemos que la relación entre los que usan anteojos y los que no es 3/5.
Esta relación es igual al cociente entre el número de estudiantes que usan anteojos y el número de estudiantes que no usan anteojos.
Si definimos las variables:
A = número de estudiantes que usa anteojos
B = número de estudiantes que no usa anteojos.
Tenemos la relación:
A/B = 3/5
podemos reescribir como:
A = (3/5)*B
Y también sabemos que el número total de estudiantes es 184, entonces tendríamos que:
A + B = 184.
Podemos aislar B en esta segunda ecuación para luego reemplazarlo en la primera.
Aislando B obtenemos:
B = 184 - A
Si reemplazamos esto en la otra ecuación obtenemos:
A = (3/5)*B
A = (3/5)*(184 - A)
Ahora podemos resolver esto para A.
A = (3/5)*184 - (3/5)*A
A + (3/5)*A = (3/5)*184
A*(1 + 3/5) = (3/5)*184
A*(5/5 + 3/5) = (3/5)*184
A*(8/5) = (3/5)*184
A = (5/8)*(3/5)*184
A = 69
Podemos concluir que 69 estudiantes usan anteojos.

is the sample likely to be representative of the population of her paitents if she selects every 3rd name on the list ?
Answers
It is important to note that representativeness is not solely determined by the sampling method. Other factors, such as the size of the population
To determine whether the sample is likely to be representative of the population of her patients if she selects every third name on the list, we need to consider the characteristics of the population and the potential bias introduced by the sampling method.
Sampling every third name on the list is a form of systematic sampling, where every kth element is selected from the population. This method can introduce bias if there is a pattern or regularity in the list that aligns with the characteristic of interest. In this case, if there is a pattern in the list that correlates with the patients' characteristics, selecting every third name may not result in a representative sample.
For example, if the list is arranged in alphabetical order by last name, and there is a correlation between patients' last names and their medical conditions, then selecting every third name could introduce bias. It may result in an overrepresentation or underrepresentation of certain conditions depending on the distribution of last names.
To determine the representativeness of the sample, we need to assess whether the sampling method is likely to introduce systematic bias or if the list is randomly ordered. If the list is randomly ordered and there is no known correlation between the order of the list and the patients' characteristics, selecting every third name may provide a representative sample.
However, it is important to note that representativeness is not solely determined by the sampling method. Other factors, such as the size of the population, the specific characteristics of interest, and the variability within the population, also play a role.
To make a definitive assessment of the representativeness of the sample, further information about the list and the population would be needed. Without such information, it is challenging to determine whether selecting every third name on the list would result in a representative sample of the population of her patients.

3^2 - (5 x 2^3)
HELP PLEASE
I need step by step
Answers
Answer:
\(-31\)
Step-by-step explanation:
We need to find the value of: \(3^2 - (5 * 2^3)\).
First we need to look at the BIDMAS rule.
B - Brackets
I - Indices
D - Division
M - Multiplication
A - Addition
S - Subtraction
First we need to work out what is in the brackets which is: \((5 * 2^3)\)
We look at the next rule which is Indices so we do \(2^3\) first.
\(2^3 = 2 * 2 * 2 = 8\)
Then we multiply it by the five which gets us:
\((5 * 8) =40\)
Now that we've finished with what is inside the brackets, we can work out what's outside which is:
\(3^2 = 3 * 3 = 9\).
Now we've simplified it down to:
\(9 - (40)\)
Which gets us:
\(9 - 40 = -31\)
Answer:

What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed constant value to the previous term.
This fixed value is called the common difference, and it is the same for all terms in the sequence.
We have,
The given sequence has a common difference of 4 between its consecutive terms.
To represent this sequence using a recursive formula, we can start with the first term and use the common difference of 4 to find each subsequent term.
Let's assume that the first term of the sequence is a1. Then, we can represent the second term \(a_2\) as:
\(a_2 = a_1 + 4\)
Similarly, we can represent the third term (a3) as:
\(a_3 = a_2 + 4\)
Substituting the value of a2 from the above equation, we get:
\(a_3 = (a_1 + 4) + 4 = a_1 + 8\)
We can continue this pattern to find the recursive formula for the nth term of the sequence:
\(a_n = a_{n-1} + 4\)
where \(a_1\)= 2
Thus,
The recursive formula for the given sequence is:
\(a_n = a_{n-1} + 4\)
