write the following equation in a function form.3x+4y=0
You have the following equation:
[tex]3x+4y=0[/tex]To write the previous equation in a function form consists in solving for y, just as follow:
3x + 4y = 0 subtract 3x both sides
4y = -3x divide by 4 both sides
y = -3/4 x
Hence, the function for of the given equation is:
y = -3/4 x

what is 0.5 percent of 3.2
Answer:
0.016
Step-by-step explanation:
Remember that "of" means to multiply and percent (%) means out of 100. So we would multiply 3.2 by 0.5 and get 1.6 then you move the decimal 2 times to the right and get 0.016. Have a Great Day! ;)

The least she has been charged in a month is$72.15.What are the possible numbers of minutes she has used her phone in a month?Use m for the number of minutes, and solve your inequality for m.
Given:
Ashley pays a monthly fee of $19, and she pays an additional $0.05 per minute of use. The least she has been charged in a month is $72.15.
Required:
Find the possible numbers of minutes she has used her phone in a month.
Use m for the number of minutes, and solve your inequality for m.
Explanation:
The initial amount paid by Ashley = $19
The additional amount per minute = $0.05
Let the number of minutes used in the phone = m
The least amount that is charged in a month = $72.15
Now by using the given information
[tex]19+0.05m\ge72.15[/tex]Solve for m as:
[tex]\begin{gathered} 0.05m\ge72.15-19 \\ 0.05m\ge53.15 \\ m\ge\frac{53.15}{0.05} \\ m\ge1063 \end{gathered}[/tex]Thus at least 1063 minutes were used on Ashley's phone in a month.
Final Answer:
The least possible minutes are 1063.
two sets of 5 different numbers that have the same standard deviation but different mean
The sets of 5 different numbers with same standard deviation but different mean are {2,4,6,8,10} and {20,22,24,26,28}.
The standard deviation is a statistic that describes the degree of volatility or dispersion in a set of numerical values.
Values having a low standard deviation are more likely to be within a narrow range of the mean (also known as the anticipated value) of the collection than values with a high standard deviation.The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is equal to the square root of that variable's variance. It is more algebraically straightforward than the average absolute deviation, but being less reliable in practice. The standard deviation is a useful statistic because, unlike the variance, it is expressed in the same unit as the data.Let us consider two data sets :{2,4,6,8,10} and {20,22,24,26,28}
Now for the first set:{2,4,6,8,10}
Mean = (2+4+6+8+10)÷5 = 30÷5 = 6
Standard deviation = 3.16
Now for the second set:{20,22,24,26,28}
Mean = (22+24+26+28+20)÷5 = 120÷5 = 24
Standard deviation = 3.16
Therefore these two data sets have same standard deviation but different mean.

Write a system of equations to describe the situation below, solve using substitution, and fillin the blanks.For her parents' anniversary party, Laura is considering using one of two venues. A hotel in Dayton will cost $693 for a reservation, plus $51 per person. A restaurant in the same city will cost $60 per person, in addition to $684 for the reservation. In order to make the best decision. Laura figures out how many attendees it would take to have the venues cost thesame amount. How many attendees would that be? What would the total cost be?
Answer:
• The number of attendees = 1
,• Total Cost = $744
Explanation:
Let the number of attendees = n
A hotel in Dayton will cost $693 for a reservation, plus $51 per person.
[tex]\text{ Hotel's Cost, H\lparen n\rparen}=693+51n\cdots(1)[/tex]A restaurant will cost $60 per person, in addition to $684 for the reservation.
[tex]\text{ Restaurant's Cost, R\lparen n\rparen}=684+60n\cdots(2)[/tex]We want to find the number of attendees(n) at which the venues cost the same amount.
Equate the cost equations (1) and (2) above:
[tex]693+51n=684+60n[/tex]Solve the equation for n:
[tex]\begin{gathered} \text{Subtract 51n from both sides of the equation.} \\ 693+51n-51n=684+60n-51n \\ 693=684+9n \\ \text{Subtract 684 from both s}\imaginaryI\text{des of the equat}\imaginaryI\text{on} \\ 693-684=684-684+9n \\ 9=9n \\ \text{ Divide both sides by 9} \\ \frac{9}{9}=\frac{9n}{9} \\ n=1 \end{gathered}[/tex]The number of attendees it would take for the cost to be the same amount is 1.
We determine the total cost using any of the equations:
[tex]\begin{gathered} \begin{equation*} 693+51n\cdots(1) \end{equation*} \\ Total\text{ Cost}=693+51(1)=\$744 \end{gathered}[/tex]The total cost will be $744.
