b. ¿Qué fracción representa el total de sillas ocupadas durante los tres días?
vean la imagen estoy en examen pliss ayudAAAAAAAAAAA
Answers
The fraction that represents the total number of seats occupied during the three days is 1.
The total number of seats in the auditorium is 200.
On day 1, 40% of the seats were occupied. So, 40/100 * 200 = 80 seats were occupied on day 1.
On day 2, 35% of the seats were occupied. So, 35/100 * 200 = 70 seats were occupied on day 2.
On day 3, 25% of the seats were occupied. So, 25/100 * 200 = 50 seats were occupied on day 3.
The total number of seats occupied during the three days is 80 + 70 + 50 = 200 seats.
The fraction that represents the total number of seats occupied during the three days is 200/200 = 1.
Here is the solution in mathematical form:
Let x be the fraction that represents the total number of seats occupied during the three days.
Then, x * 200 = 80 + 70 + 50
x = (80 + 70 + 50) / 200
x = 1
Therefore, the answer is 1.

A cell phone company $500 for a new phone and $60 for a monthly plan. If C(t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function?
A. R: (0,500)
B. R: (60,560)
C. R: R
C: R: (-infinity, infinity)
HOW DO I SOLVE THIS?!
Answers
The range of a function is the set of possible values that can be obtained from the dependent variable. The range of the function is: [tex]R: (500, \infty)[/tex]
Given that:
[tex]Phone = \$500[/tex]
[tex]Monthly\ Plan = \$60[/tex]
Let the number of months be t. So, the function C(t) is calculated as follows:
[tex]C(t) = Phone + Monthly\ Plan \times t[/tex]
[tex]C(t) = 500 + 60 \times t[/tex]
[tex]C(t) = 500 + 60t[/tex]
The range is calculated as follows:
The smallest possible value of t is 0 i.e. when no monthly subscription is done.
So, we have:
[tex]C(0) = 500 + 60\times 0= 500 + 0 = 500[/tex]
And the highest is [tex]\infty[/tex] i.e. for a large value of t
So, we have:
[tex]C(\infty) = 500 + 60\times \infty= 500 + \infty = \infty[/tex]
Hence, the range of the function is:
[tex]R: (500, \infty)[/tex]

One bolt of cloth will make shirts for 47 people. How many bolts are needed for 376 people?
Answers
Answer:
8
Step-by-step explanation:
the relationship of one "unit" (bolt) of cloth to 47 people makes this number (47 people) also an unit.
to answer the question we need to find out, how many units fit into the target.
how do we do that ? by division.
when we divide a/b, then we are actually asking, how many times does b fit into a.
so, how many bolts are needed for 376 people ?
well, how often does 47 fit into 376 ? how often can we build groups of 47 people out of the 376 ?
the answer
376 / 47 = 8
so, 8 bolts are needed.
Answer:
1 bolts = 47 people
so, 47+47+47+47+47+47+47+47= 376 people
The answer is 8 bolts

We are asked to find multiple probabilities.
We got to find the number of combinations posible,
Use the combinations formula
[tex]c {}^{n} _r{?} = \frac{(r + n - 1) \: fractorial).}{r \: fractorial(n - 1)fractorial} [/tex]
For math this is read as,
if n choose r,( r+n-1)!/r!(n-1)!.
Where r is how many things we need from and n is the number of things we choose from.
We need 2 things and we have 24 objects to pick from.
So r=2 N equal=24
Which equal
25!/2!(23)!
Which equals
[tex]300[/tex]
So there are 300 possible combinations.
Using
For the 1st question, Since we are given two independent events, we can just multiply the number of good articles by major.
[tex]14 \times 4 = 56[/tex]
So this means the probability is
[tex] \frac{56}{300} = \frac{14}{75} [/tex]
Which is 19%
For the 2nd question, the can multiply the number of minor articles by major articles.
[tex]6 \times 4 = 24[/tex]
So the probability
is
[tex] \frac{24}{300} = \frac{8}{100} = \frac{2}{25} [/tex]
Which is equal to 8%

Sasha places an online order. In addition to the price of the item she orders, she pays 5% tax and a flat shipping fee of $15. The total cost of her order is $141. What is the price of the item she orders?
Answers
Answer:
$120Step-by-step explanation:
Let the price is x.
Set the equation and solve for x:
(x + 5%) + 15 = 1411.05x + 15 = 1411.05x = 126x = 126/1.05x = 120Answer:
$119.7
Step-by-step explanation:
Shipping is typically taken after tax so we can subtract shipping and find the tax.
141 - 15 = 126
126 * 0.05 = 6.3
Now we can subtract to find what she spent on items.
126 - 6.3 = 119.7

Answer:
The statement in the question is wrong. The series actually diverges.
Step-by-step explanation:
We compute
[tex]\lim_{n\to\infty}\frac{n^2}{(n+1)^2}=\lim_{n\to\infty}\left(\frac{n^2}{n^2+2n+1}\cdot\frac{1/n^2}{1/n^2}\right)=\lim_{n\to\infty}\frac1{1+2/n+1/n^2}=\frac1{1+0+0}=1\ne0[/tex]
Therefore, by the series divergence test, the series [tex]\sum_{n=1}^\infty\frac{n^2}{(n+1)^2}[/tex] diverges.

Complete the slope-intercept form of this line.
y=-4x +
Answers
Answer:
It is y = -4x + 9
Step-by-step explanation:
General equation of a line:
[tex]y = mx + c[/tex]
For a y-intercept, c :
consider point (2, 1):
y is 1, x is 2 and m is -4
[tex]y = mx + c \\ 1 = (2 \times - 4) + c \\ 1 = - 8 + c \\ c = 1 + 8 \\ c = 9[/tex]
therefore, equation is:
[tex]y = - 4x + 9[/tex]
The complete form of the equation is y = - 4x + 9
The slope intercept form of the line is given as:
y = - 4x + c
Where c = intercept , we need to calculate, c
Take any given value of y and x and substitute into the equation, the solve for c
Take x = 1, y = 5
5 = - 4(1) + c
5 = - 4 + c
Add 4 to both sides
5 + 4 = - 4 + c + 4
9 = c
Hence, the complete form of the equation is y = - 4x + 9

Please let me know if you have any questions
Answer:
Stack the two equations and add them together as if they were multi-digit numbers. That will eliminate the x and then you can solve for the y. Knowing y you can then go back and solve for x.
Step-by-step explanation:
x + 5y = 11
-x + 4y = 7
---------------- "Add" the equations above to get the equation below.
9y = 18
Now you can divide both sides by 9 to see that y is equal to 2.
Now that you know that y = 2 you can substitute y in either of the two original equations. I'll use the first.
x + 5(2)= 11
x + 10 = 11
