A sports center offers party packages. They advertise a flat rate of $325 for the first 10 guests. They charge $15 per person for each additional guest. A formula for the cost of the party is:
C = 325 + 15p
where p is the number of guests more than 10. (For example, if 12 people come to the party, p = 2.) Suppose you want to have a huge birthday celebration this year. However, you have budgeted $600 for your party. How many guests can you invite if you decide to have your party at this sports center?
Answers
Using the given linear equation, we conclude that you can invite a maximum number of 21 guests.
How many guests can you invite if you decide to have your party at this sports center?Here the function is:
C(p) = 325 + 15*p
Where p is the number of guests minus 10, now we know that your budget is $600, then the maximum value of guests allowed is such that:
C(p) = 600 = 325 + 15*p
Now we can solve this equation for p:
600 - 325 = 15*p
275 = 15*p
175/15 = p = 11.67
Then the maximum whole number that p can take is p = 11
This means that the maximum number of guest that you can have is:
Guests = 10 + p = 10 + 11 = 21.

A small company has 6 employees with associate degrees, 2 employees with bachelor's degrees, and 8 employees with master's degrees. If a single employee is picked at random, what is the probability that he or she has a bachelor's or a master's degree
Answers
Using it's concept, there is a 0.625 = 62.5% probability that he or she has a bachelor's or a master's degree.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The company has 6 + 2 + 8 = 16 employees, out of which 2 + 8 = 10 have a bachelor's or a master's degree, hence the probability is:
p = 10/16 = 0.625.
0.625 = 62.5% probability that he or she has a bachelor's or a master's degree.

Answer:

Step-by-step explanation:
Let the numbers be x and y
Given condition:x + y = 48 --------(1)
y = 7x -------------(2)
Put Eq. (2) in (1)
x + 7x = 48
8x = 48
Divide 8 to both sides
x = 48/8
x = 6Put x = 6 in Eq. (2)
y = 7 (6)
y = 42[tex]\rule[225]{225}{2}[/tex]
Assume a is the 1st number and b is the 2nd number, a + b = 48
b = 7a (the second number is seven times the first number)
a = a
So, equation: a + 7a = 48
a + 7a = 48
8a = 48
a = 6
To find b = 7 (6) = 42

The depth of the water = 15 × tan(4°) = 1.049 m
The height of Brooke's boot = 1 m
Therefore;
Brooke's cannot bring the boat back without getting water over her boots.2. The angle of elevation of the plan = arccos(99/100) ≈ 8.110°
Given that the angle of elevation the plan, 8.110°, is more than 8° limit, we find;
The plan will not be approved.3. Height reached by the plane = 9 × tan(21°) = 3.455
Therefore;
The plane will not disturb.4. Height of the chimney at the factory = 50 × tan(51°) = 61.745
The minimum chimney height = 65 m.
Therefore;
The company can not use the chimney legally.6. Length of the bridge = 72 × tan(55°) ≈ 102.83
Therefore;
The Long company will build the bridge because it is longer than 100 m. but not more than 103 m.7. Height reached by the ladder = 26 × sin(43°) ≈ 17.7
Therefore;
The fireman can reach her.8. Height reached by the ski lift = 1000 × sin(29°) ≈ 484.8
Therefore;
The lift does not take the skiers up to the bar.9. Height reached by plane = 26 × tan(9°) ≈ 4.12
The plane flies under the cloud therefore;
Eric will be able to see his Dad's plane.10. Length required for the metal brace = 21/(cos(73°)) ≈ 71.83

Which ordered pair below is a solution to the following system of equations? x + 2y = 7 2x − y = -1
Answers
Answer: (1,3)
Step-by-step explanation:
Let's solve this system of equations by elimination. We will multiply one or both equations such that when we combine the equations, one of the variables will completely cancel out.
Let's multiply the whole first equation by -2 to achieve this:
[tex]-2(x+2y=7)[/tex] now becomes [tex]-2x-4y=-14[/tex]
Now let's add both equations
[tex]-2x-4y=-14[/tex]
[tex]2x-y=-1[/tex]
[tex]-5y= -15[/tex]
Since we got y into a form we can solve it for, lets divide both sides by -5 to isolate it.
[tex]\frac{-5y}{-5} = \frac{-15}{-5}[/tex]
[tex]y=3[/tex]
Now that we have the value of y, we can substitute it into any equation to solve for x. Only if we have both x and y can we make an ordered pair. Let's use the second equation and substitute 3 for y.
[tex]2x-3=-1[/tex]
We can now solve for x.
[tex]2x=2[/tex] [Adding 3 to both sides]
[tex]x=1[/tex] [Dividing by 2 on both sides]
We now have both x and y, so we can put it in an ordered pair to answer the question.

To determine where the given t-value would fall, we look for the row with heading d.f. =11. In this row, the sample statistic t = 1.910 falls between t = 1.796 and t = 2.201
How to determine the t values?The given parameters are:
Degree of freedom, df = 11Sample statistic, t = 1.910This means that
df = 11 and t = 1.910
To calculate the t value,
We check the row where the heading of the degree of freedom is 11
i.e. df = 11
On this row, the t value 1.910 would be between 1.796 and 2.201
This is because 1.910 is greater than 1.796 and it is less than 2.201
Hence, the complete statement is

= 3
By using the Excel function, the p-value is given as 0.0002. In this case, we've to reject the null hypothesis if the p value is less than 0.1.
Therefore, we will reject the null hypothesis in this case. In inferential statistics, the null hypothesis is that two possibilities are the same. It is observed difference is due to chance alone. Using statistical tests, it is possible to calculate the likelihood that the null hypothesis is true

en una fiesta hay 16 personas de las cuales el 25% son mujeres, luego llegan mas mujeres a la fiesta, de tal manera que ahora los hombres son el 60% ¿cuantas mujeres llegan a la fiesta?
Answers
Answer:
English (Ingles):
10 Women come to the party.
Spanish (Espanol):
10 Las mujeres vienen a la fiesta.
Step-by-step explanation:
English (Ingles):
We know that there are 16 people there at the start. 25% of those people are women. We can work out by subtracting 100 by 25 that 75% of the p-eople there are men. We need to do 25% of 16 so we can work out how many men and women there are there.
So we find 10% of 16 which is 1.6 then we take off 5% of 1.6 which is 0.08. We then double 1.6 to get 20% which gives us 3.2. We now add on the 5% to make it 25% which gives us 4.
This means 25% of 16 is 4.
This tells us that there are 4 women at the party and 12 men as 16 - 4 = 12.
It now says that more women arrive which makes the percentage for men go down to 60%. We now need to add 5% on to the 25% of women there are which will tell us how many more women there are now and it will let us work out how many women and men there are in total now.
As we can't do this without it giving us 4.8, we know that 25% of people is 4 women which means 50% of people would be 8 women and we make an estimate of how many women have joined which gives us 6 people which means the total amount of women at the party is 10.
Spanish (Espanol):
Sabemos que hay 16 personas allí al principio. El 25% de esas personas son mujeres. Podemos calcular restando 100 por 25 que el 75% de las personas son hombres. Necesitamos hacer el 25% de 16 para poder calcular cuántos hombres y mujeres hay allí.
Así que encontramos el 10 % de 16, que es 1,6, luego quitamos el 5 % de 1,6, que es 0,08. Luego duplicamos 1,6 para obtener el 20%, lo que nos da 3,2. Ahora sumamos el 5% para convertirlo en 25%, lo que nos da 4.
Esto significa que el 25% de 16 es 4.
Esto nos dice que hay 4 mujeres en la fiesta y 12 hombres como 16 - 4 = 12.
Ahora dice que llegan más mujeres lo que hace que el porcentaje de hombres baje al 60%. Ahora necesitamos agregar un 5% al 25% de mujeres que hay, lo que nos dirá cuántas mujeres más hay ahora y nos permitirá calcular cuántas mujeres y hombres hay en total ahora.
Como no podemos hacer esto sin que nos dé 4.8, sabemos que el 25% de las personas son 4 mujeres, lo que significa que el 50% de las personas serían 8 mujeres y hacemos una estimación de cuántas mujeres se han unido, lo que nos da 6 personas que significa que la cantidad total de mujeres en la fiesta es 10.

nine is subtracted from the number(10x+y) - 9
= 10y+x
x + y = 5
9x - 9y = 9
x + y = 5
x - y = 1
Add the equations
2x = 6
x = 6/2
x = 3
substitute into
x + y = 5
3 + y = 5
y = 5 - 3
y = 2
Therefore, the unknown number is 32.
