We hava a basket of eggs, but we don't know how many there are in the basket.
Lets call X the number of eggs in the basket.
We know that if we take 3 eggs at a time or 7 eggs at a time, there are one egg left in the basket.
That means the residual of the division X/3 and X/7 is 1.
We know that if we take 8 eggs at a time, there are no eggs left in the basket.
That means the residual of the division X/8 is 0 (or X is multiple of 8).
We also know X is less or equal to 100.
\(\begin{gathered} X-3m=1 \\ X-7n=1 \\ X-8h=0 \end{gathered}\)We have to find a number that is divisible by 7 and 3, and then add 1 and verify that is divisible by 8.
As 7 and 3 have no common denominator, we have to find a number that is divisible by 7*3=21 and then add 1 and verify that is divisible by 8.
We can check one by one:
If we add 1 to 21, we have 22. It is not divisible by 8, so it is not the value of X.
The next number is (2*21) + 1 = 42 + 1 = 43. It is not divisible by 8.
The next number is (3*21) + 1 = 63 + 1 = 64. It is divisible by 8, so this is the value of X.
The number of eggs in the basket is 64.
Equations
X-21n=1
X-8m=0
8m=1-21n
m=(1-21n)/8 and m has to be a positive integer.
We can iterate n=1,2,3.... until we find an m that is a positive integer.
Two methods to solve (X+3)^2=6
The solution of the given equation is \(-3+\sqrt{6}\) and \(-3-\sqrt{6}\).
Given equation:-
\((x+3)^2=6\)
We have to find the value of x by solving the given equation.
We can rewrite the given equation as:-
\(x^2+6x+9=6\\x^2+6x+3=0\)
We can solve the the quadratic equation by finding the discriminant.
\(x = \frac{-6+-\sqrt{6^2-4*1*3} }{2*1}\)
\(x = \frac{-6+-\sqrt{36-12} }{2}\)
\(x=\frac{-6+-2\sqrt{6} }{2}=-3+-\sqrt{6}\)
Hence, the values of x are \(-3+\sqrt{6}\) and \(-3-\sqrt{6}\).
Discriminant
In arithmetic, a polynomial's discriminant is a function of the polynomial's coefficients.
Quadratic equation
The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of:

find the measures of one interior angle and one exterior angle of a regular polygon with 8 sides
one interior angle__________ one exterior angle___________
Answer:
one interior angle 135
one exterior angle 45
Step-by-step explanation:
Total measure of all angles in a 8 sided regular polygon = (n - 2)* 180
= ( 8 - 2 ) * 180
= 6 * 180
= 1080
Measurement of one interior angle = 1080 / 8 = 135
Interior angle and exterior angle make linear pair.
Measurement of one exterior angle = 180 - 135 = 45

Melinda is playing a game with a number cube. Each face of the cube has a number from 1 to 6. If she tosses a number greater than 4she wins the round. Which statement correctly describes her chances of winning?
A)Melinda will certainly win the round.
B)Melinda will most likely win the round.
C)Melinda has an equal chance of winning or not winning the round.
D)Melinda will most likely not win the round.
Answer:
Step-by-step explanation:
She wins if the numbers 5 or 6 come up. There are 4 other numbers that are equally likely to be face up.
Most of the time she will lose because two out of 6 is much smaller than 4/6. If you were betting on horses, the odds are 1 in 2. That means that who ever you are playing against should put up 2 dollars for every dollar you put up.

How to find the type of statistics sampling?There are different ways that samples are classified such as:
1) Convenience sampling: This is where samples are drawn from a conveniently available pool.
2) Random Sampling: This is when we put all the options into a particular hat and drawn some of them.
3) Systematic Sampling: This is when every nth element is taken. For example, we want to survey something in the school, and then we interview every 10th person.
4) Cluster Sampling: This usually divides a population into groups, referred to as clusters, and each element in that cluster is surveyed.
5) Stratified Sampling: This will divide the population into groups. However, unlike cluster sampling, here, only some elements of the group are surveyed.

uppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5 and a standard deviation of 0.37. Using the empirical rule, what percentage of the students have grade point averages that are no more than 3.24
Answer:
\(P(x \le 3.24) = 0.97725\)
Step-by-step explanation:
Given
\(\bar x = 2.5\)
\(\sigma = 0.37\)
Required
Percentage that is not more than 3.24
The above implies that:
\(x = 3.24\)
Calculate z score
\(z = \frac{x - \bar x}{\sigma}\)
\(z = \frac{3.24 - 2.5}{0.37}\)
\(z = \frac{0.74}{0.37}\)
\(z = 2\)
So, the probability is represented s:
\(P(x \le 3.24) = P(z \le 2)\)
From z probability
\(P(z \le 2) = 0.97725\)
Hence:
\(P(x \le 3.24) = 0.97725\)

the angle of elevation from the bottom of a slide to the top of the slide is 44 if the top of the slide sits 16 feet above the ground
The length of the slide is approximately 16.56 feet.
To solve this problem, we can use basic trigonometry.
The angle of elevation refers to the angle between the horizontal ground and the line of sight from the bottom of the slide to the top of the slide.
Given that the angle of elevation is 44 degrees and the height of the top of the slide is 16 feet, we can use the tangent function to find the length of the slide.
The tangent of an angle is equal to the ratio of the opposite side to the adjacent side.
The opposite side is the height of the slide (16 feet), and the adjacent side is the length of the slide that we want to find (let's call it x).
So, we have:
tan(44 degrees) = 16 feet / x
To solve for x, we rearrange the equation:
x = 16 feet / tan(44 degrees)
Using a calculator, we can find the value of the tangent of 44 degrees, which is approximately 0.9659.
Thus, we can calculate:
x = 16 feet / 0.9659
≈ 16.56 feet

En una prisión federal para mujeres, 100 de las 240 internas tienen puntos de vista izquierdistas. Si se elige al azar a 5 de ellas para comparecer ante el juzgado, determine la probabilidad de que solo una de ellas tendrá
ideas políticas de izquierda.
Answer: La probabilidad es 0.24
Step-by-step explanation:
De 240 personas, sabemos que 100 tienen una vista izquierdista.
Entonces la probabilidad de que una persona, seleccionada al azar, tenga una vista política izquierdista es:
Pa = 100/240 = 5/12
Entonces la probabilidad de que una persona elegida al azar NO tena una vista política izquierdista, es:
Pb = 1 - Pa = 1 - 5/12 = 7/12.
Queremos calcular la probabilidad que de 5 personas elegidas al azar, solo una tenga una vista izquierdista.
Entonces vamos a tener Pa una vez, y Pb 4 veces.
Y como sabemos, la probabilidad conjunta es igual al producto de las probabilidades, entonces:
p = Pa*Pb^4 = (5/12)*(7/12)^4
Pero esto va a ser para un solo arreglo (por ejemplo, de las 5 personas electas, la primera tiene una visión izquierdista), entonces tenemos que tener en cuenta las permutaciones, que van a ser las posibles permutaciones de un elemento en un espacio de 5 posibles espacios.
Son 5 permutaciones, y estas son:
La primera tiene visión izquierdista.
La segunda tiene visión izquierdista.
La tercera tiene visión izquierdista.
La cuarta tiene visión izquierdista.
La quinta tiene visión izquierdista.
Que también es igual a la combinatoria de 5 en 1.
\(C(5,1) = \frac{5!}{(5 - 1)!*1!} = 5\)
Entonces la probabilidad que buscamos va a ser:
P = 5*p = 5*(5/12)*(7/12)^4 = 0.24

So column 1 says 1/2 package of pencils and there are 24 pencils in that package so you have 12 pencils total not 24 like it says.
Column 2 says 1 package of pencils. Since there are 24 pencils in a package, now you would have 24 pencils total.
Column 3 says 3 packages. 3 x 24 = 72 pencils total
Column 4 says 4 packages. 4 x 24 = 96 pencils total
Colum 5 says 6 1/2 packages. 6 x 24 = 144 and you know 1/2 of a package equals 12. So 144 + 12 = 156 total pencils.
