En una librería se venden novelas a 16 euros y guías de viaje a 10 euros. Si hoy se han vendido 37 libros en total con una recaudación de 508 euros, calcula el número de ejemplares vendidos de cada tipo.
Answer:
En la librería se vendieron 23 novelas y 14 guías de viaje.
Step-by-step explanation:
Con la información proporcionada puedes plantear las siguientes ecuaciones:
x+y=37 (1)
16x+10y=508 (2), donde:
x es el número de novelas vendidas
y es el número de guías de viaje vendidas
Primero, puedes despejar x en (1):
x=37-y (3)
Ahora, debes reemplazar (3) en (2) y despejar y:
16(37-y)+10y=508
592-16y+10y=508
592-508=16y-10y
84=6y
y=84/6
y=14
Después, debes reemplazar el valor de y en (3) para encontrar el valor de x:
x=37-14
x=23
De acuerdo a esto, la respuesta es que en la librería se vendieron 23 novelas y 14 guías de viaje.

Answer:
17r = 595 is the answer
Step-by-step explanation:
Answer:
A) 17r = 595 is the correct equation.
Step-by-step explanation:
We have to find the no. of rooms on each floor.
If there are 'r' rooms, and in 17 floors there are a total of 595 rooms,
We can represent it in the following equation:
17r = 595
r = 595/17
r = 35
∴ There are 35 rooms on each floor
A scientist claims that 6% of viruses are airborne. (a) If the scientist is accurate, what is the probability that the proportion of airborne viruses in a sample of 529 viruses would be greater than 8%? Round your answer to four decimal places.
Answer:
Probability that the proportion of airborne viruses in a sample of 529 viruses would be greater than 8% is 0.9545.
Step-by-step explanation:
For the given population the distribution of air-borne viruses is given as 6%. Now for this the value of Z score is given as
[tex]Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}}[/tex]
Here
[tex]\hat{p}[/tex] is the sample measure which is 8% or 0.08p is the population measure which is 6% or 0.06n is the number of samples which is 529So the Z score is given as
[tex]Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}}\\Z=\dfrac{0.08-0.06}{\sqrt{\dfrac{0.08(1-0.08)}{529}}}\\Z=\dfrac{0.02}{\sqrt{\dfrac{0.08(0.92)}{529}}}\\Z=\dfrac{0.02}{\sqrt{\dfrac{0.0736}{529}}}\\Z=\dfrac{0.02}{0.01179}\\Z=1.6955[/tex]
For this the score, the value of probability is calculated from the table as below:
[tex]P(\hat{p}>0.08)=p(Z>1.6955)\\=1-p(Z<-1.6955)[/tex]
Here value of p(Z<-1.6955) is given as 0.0455
[tex]P(\hat{p}>0.08)=p(Z>1.6955)\\P(\hat{p}>0.08)=1-p(Z<-1.6955)\\P(\hat{p}>0.08)=1-0.0455\\P(\hat{p}>0.08)=0.9545[/tex]

Solve for x in the following equations: -8x -10y = -6 when y = 3
A) -3
B) -6
C) 4
D) -2
Answer:
x = - 3
Step-by-step explanation:
- 8x - 10(3) = - 6
- 8x - 30 = - 6
- 8x - 30 + 30 = - 6 + 30
- 8x = 24
- 8x ÷ - 8 = 24 ÷ - 8
x = - 3
Answer:
the answer is A -3
Step-by-step explanation:
-8x-10y=-6 when y=3
-8x-10(3)=-6
-8x-30=-6
-8x=-6+30
-8x=24
-8x÷8=24÷8

The high school softball team needs to buy T-shirts for their games. The T-shirts cost $8 a piece and they only have $100 to spend.
Answer:
100-(8 times y)
Step-by-step explanation:
The high school softball team needs to buy T-shirts for their games. The T-shirts cost $8 a piece and they only have $100 to spend.
8 a peice
This means that the money costs 8$ for each of the players. We don't know how many players there are, so we will just label the amount of players as "y"
And we will multiply 8 times y to get our answer
And then we will subtract THAT answer minus 100 to get our full answer.
Hope this helps!

In chapter 1, we introduced several sampling methods: Simple random sample, stratified sampling, systematic sampling, and cluster sampling. All the sampling methods except for convenience sampling, allow for unbiased statistical inference to be made. Convenience sampling typically leads to an unrepresentative sample and biased results. In this week's discussion board, you are asked to design a sample that is representative of the population and unbiased. Scenario: A marketing executive for Coca- Cola, Inc. wants to identify television shows that people in the Seattle area who typically drink Coke are watching. The executive has a list of all households in the Seattle area. Task: You are asked to design a sample to obtain the individuals in the sample. Use the provided scenario to help the Coca-Cola executive identifying the television shows. Design a sample that meets the requirements we discussed in the previous chapter. You need to explain why did you choose this sampling method.
Answer:
For the coca-cola case, stratified sampling coupled with random sampling will be used.
Step-by-step explanation:
Before going into discussing the scenario, it is evident to discuss the properties of mentioned sampling methods. They are as follows:
Random sampling as the name indicates is purely by randomness. It is a sample in which each element of the population has an equal chance of coming on.
Systematic sampling is easier than random sampling. Here all the elements are arranged in an order and the kth element is considered after a specific interval.
Cluster Sampling is another type of sampling where the population is divided into groups probably on the basis of their geographical location and all the elements of the cluster are then used.
Stratified Sampling is a two-step sampling method where firstly the population is divided into strata, groups on basis of some characteristic, like gender, age, and then another sampling method as the random or systematic method is chosen to pick samples from each of these strata.
On the basis of properties presented and the scenario outlined, it is evident that the population will be divided into strata based on age, gender, profession, and education, and then a random sampling within each stratum is used for all the population of the Seattle area.

Henri puts aside $10 cash every month in a shoebox. He also makes a one-time deposit of $1,500 in a savings
account at 9% annual interest, compounded yearly,
Amount of shoebox savings: f(t) = 120t
Amount of savings account: g(t) = 1,500(1.09)^t
Which function represents the amount of money Henri will have after t years?
Answer:
T(t) = f(t) + g(t)
Step-by-step explanation:
The function which represents the total amount of money Henri will have in t years is the function obtained using an addition operation in the two defied functions, f(t) and g(t) ; total amount saved in shoe box plus the total compounded amount in savings account
Total amount of money in t years, T(t) ;
T(t) = 120t + 1,500(1.09)^t
f(t) = 120t
g(t) = 1,500(1.09)^t
Hence,
T(t) = f(t) + g(t)

The equation y =f(x) is graphed on the coordinate plane. A function, g(x). is the result of translating the graph of fuxi to the left 2 units and up 4 units. Which is an equation for g(x)?
A)g(x)=f(x - 2)+4
B)g(x) = f(x + 2) + 4
C)g(x)=f(x-4)-2
D)g(x)=f(x + 4)-2
Answer:
A
Step-by-step explanation:
g
[tex]g(x) = f(x - 2) + 4[/tex]
A function assigns the value. The equation of the function g(x) will be f(x-2)+4.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x) is a function which is shifted two units to the right and 4 units upwards. Therefore, in the function f(x) we need to add -2 to the value of the x for the function to move right, while we need to add 4 to the overall function to move it four units upwards.
Hence, the equation of the function g(x) will be f(x-2)+4.

Dieego is making a large mural he draws a hexagon with a perimeter of 10.5 meters each side is the same length. How amny meters long is diegos hexagon
Answer:
1.75m
Step-by-step explanation:
Given;
Perimeter of the hexagon = 10.5metres
Required
Side length of the hexagon
Since hexagon has 6 equal sides, hence the perimeter is expressed as;
P = 6a
a is the side length of the hexagon
Substitute the perimeter given
10.5 = 6a
a = 10.5/6
a = 1.75metres
Hence the length of each side of the hexagon is 1.75m

Solve for xxx. Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions. 54x+64 \geq 49x + 5954x+64≥49x+59
Answer:
x ≥-1
Step-by-step explanation:
Given the inequality
54x+64≥49x+59
Collect the like terms
54x - 49x ≥ 59 - 64
5x ≥ -5
Divide both sides by 5
5x/5 ≥ -5/5
x ≥ -1
