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.

Also, we have the graphs to be f(x) and g(x)
The equation of the first graph is illustrated by the blue curve f(x), while the second is illustrated by the red curve
Because the function is f(x), we make use the blue curve
On the blue curve, we have

What is a random variable?The mathematical formalization of a number or object that is subject to chance events is known as a random variable. It is a function or mapping between a sample space of potential outcomes to a measured space, frequently the real numbers.
A random variable is a variable with an unknown value or a function that gives values to each of the results of an experiment. A random variable is a numerical representation of the result of an experiment in statistics. Discrete random variables are those that can only take on a finite number or an infinite series of values.
According to the provided information, it is known that a bottle of water contains 12.05 fluid ounces; hence it is clear that the random variable X will be the ounces of water.

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.
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
Graph the line with the equation y = 2x - 1.
A line is uniquely defined by two points.
Since the points (0, -1) and (1, 1) lie on the graph (since they satisfy the equation), you can draw the line through these points.

The number of chocolate chips in an 18-ounce bag of
Chips Ahoy! chocolate chip cookies is approximately
normally distributed with a mean 1262 chips and a

What percent of bags has between 1026 and 1380 chocolate chips? Write your percent without the percent sign.
What percentage of the 18-ounce bags of chips ahoy! Cookies contains fewer than 1144 chocolate chips? Write the percent without the percent sign.
What percentage of the 18-ounce bags of chips ahoy! Cookies contains more than 1498 chocolate chips? Write the percent without the percent sign.
Using the normal distribution, it is found that:
81.85% of bags has between 1026 and 1380 chocolate chips.15.87% of the bags contain fewer than 1144 chocolate chips.2.28% of bags contain more than 1498 chocolate chips.Normal Probability DistributionThe z-score of a measure X of a variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the fraction presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above or below the mean of the distribution, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation of the number of chips are given as follows:
[tex]\mu = 1262, \sigma = 118[/tex]
The proportion of bags that has between 1026 and 1380 chocolate chips is the p-value of Z when X = 1380 subtracted by the p-value of Z when X = 1026, hence:
X = 1380:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1380 - 1262)/118
Z = 1
Z = 1 has a p-value of 0.8413.
X = 1026:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1026 - 1262)/118
Z = -2
Z = -2 has a p-value of 0.0228.
0.8413 - 0.0228 = 0.8185.
Hence the percentage is 81.85%.
The proportion that has fewer than 1144 chips is the p-value of Z when X = 1144, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1144 - 1262)/118
Z = -1
Z = -1 has a p-value of 0.1587.
Hence the percentage is of 15.87%.
The proportion that has more than 1498 chips is one subtracted by the p-value of Z when X = 1498, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1498 - 1262)/118
Z = 2
Z = 2 has a p-value of 0.9772.
1 - 0.9772 = 0.0228
Hence the percentage is of 2.28%.
