a movie club charges a one time fee of $25 it allows members to purchase movies for $7 each another club does not charge a membership fee and sells movies $12 how many movies must a member purchase for the total cost of the two clubs to be equal
Answers
No membership club = $12 per movie(x)
We need to know how many movies must each purchase to equal in costs.
Set up both equations to equal each other and solve for x=movies.
25 + 7x= 12x
25 + 7x -7x = 12x - 7x
25= 5x
25/5=5x/5
5=x it will take them both 5 movies each to have equal costs.
The number of movies in which the total cost of the two clubs should be equal is 5.
Given that,
The one-time fee is $25.The other club should be $7.The selling price of the movies should be $12.Let us assume the number of movies be x.25 + 7x= 12x
Now put -7x in both sides
So,
25 + 7x -7x = 12x - 7x
25= 5x
x = 5
Therefore we can conclude that the number of movies in which the total cost of the two clubs should be equal is 5.

Tina and Bruce are each rolling a 1 to 6 number cube . they are looking for different ways to roll two factors whose product is greater than 14. how many different ways will they find ?
Answers
Final answer:
To find the different ways to roll two factors whose product is greater than 14, we list the different outcomes when rolling a number cube twice.
Explanation:
To find the different ways to roll two factors whose product is greater than 14, we need to consider the possible outcomes when rolling a number cube twice.
First, we look at the factors of 14 and determine that they are 1, 2, 7, and 14.
Now, we can list the different ways to roll two factors:
If Tina rolls a 1 and Bruce rolls a 15 (6 + 9), the product is 15 which is greater than 14.
If Tina rolls a 2 and Bruce rolls a 10 (3 + 7), the product is 20 which is greater than 14.
If Tina rolls a 7 and Bruce rolls a 3, the product is 21 which is greater than 14.
If Tina rolls a 14 and Bruce rolls a 2, the product is 28 which is greater than 14.
Therefore, there are 4 different ways for Tina and Bruce to roll two factors whose product is greater than 14.

How should Kalesha determine the amount she will pay for her computer?Subtract $100, then take 10% off.Take 10% off, then subtract $100.Kalesha will pay
The answer is : $710
Answers
The amount Kalesha will pay for her computer is:
$ 710
Step-by-step explanation:It is given that:
The original price of the laptop is $900.
The store is offering 10% off on all computers.
Kalesha has a $100 gift card.
Now in order to calculate the amount Kalesha will pay we first have to find the cost that will be reduced on a offer of 10% provided by the store and subtract this reduced price from the original price ; and finally we again subtract $ 100 from this resulting price.
When a offer of 10% is applied to the computer we have:
Price reduced on offer=10% of original price
i.e.
Price reduced on offer=10%×900
i.e.
Price reduced on offer=0.10×900
i.e.
Price reduced on offer=$ 90
Cost of Computer= Original price-Price reduced on offer
i.e.
Cost of computer= 900-90
i.e.
Cost of Computer=$ 810
Now, when Kalesha uses her gift card of $ 100 then,
Amount Kalesha will pay= $ (810-100)
i.e.
Amount Kalesha will pay= $ 710

Let f (x) = ax + b and g(x) = cx + d, where a, b, c, and d are constants. determine necessary and sufficient conditions on the constants a, b, c, and d so that f ◦ g = g ◦ f
Answers
[tex]g(x)=cx+d[/tex]
[tex]f\circ g(x)=a(cx+d)+b=acx+ad+b[/tex]
[tex]g\circ f(x)=c(ax+b)+d=acx+bc+d[/tex]
In order for [tex]f\circ g=g\circ f[/tex] to hold, we require [tex]ad+b=bc+d[/tex], which can be rearranged slightly as [tex](a-1)d=(c-1)b[/tex] or [tex]\dfrac{a-1}{c-1}=\dfrac bd[/tex], etc.
The necessary and sufficient conditions for f ◦ g = g ◦ f are that a and c must be non-zero and have the same sign, while b and d can be any values.
Explanation:To determine the necessary and sufficient conditions for f ◦ g = g ◦ f, we need to find the values of a, b, c, and d that satisfy this equation.
a and c must be non-zero, as dividing by zero is undefined in functions.If a and c have different signs, f ◦ g and g ◦ f will have different slopes, which means they will not be equal. Therefore, a and c must have the same sign.If a and c have the same sign, b and d can be any values, as they won't affect the slopes of the functions.Therefore, the necessary and sufficient conditions for f ◦ g = g ◦ f are that a and c must be non-zero and have the same sign, while b and d can be any values.

Answers
A quadratic function has one point where is switches from going up to going down (or down to up), but this has two, so that's not it.
A cubic function has 2 points where it goes from down to up or up to down, so this may just work.
An exponential function has a constant to the power of something, so it's either staying constantly up or down after 0 or jumping up and down with every x value, which it isn't doing.
Logarithmic functions are similar to exponential functions in that it usually stays either going up or down the whole time.
Using our definitions, a cubic function is the only one that fits
Can someone help me understand why the mean travel for women is greater than the mean travel for men?
Problem Words:
"In San Jose, the amount of time it took each person to get to work was recorded and rounded up to the nearest 555 minutes. The data collected for men and women are shown in the bar graph to the left"
Answers
To ascertain why mean travel time for women could be greater than for men, one would analyze commuting data for both genders and possibly use hypothesis testing to determine if any observed difference is statistically significant.
Explanation:Understanding the differences in mean travel time between men and women requires analysis of provided data and consideration of statistical methods. For instance, if in San Jose, the recorded commuting times were higher for women, this could be a result of many factors including job location, availability of transportation, or societal roles affecting women's work commute. In the hypothetical scenario provided, it appears there were no actual data points or a graph to refer to, but typically, one would calculate the average commute time for each gender groups and then compare the two means.
For example, if you have a dataset and you're trying to establish whether the mean travel time for women is greater than that for men, you could perform a hypothesis test. The null hypothesis would state there is no difference in the commuting times between men and women, while the alternative hypothesis would state that There is a significant difference in mean commute times. You would then use the data findings, such as sample means and standard deviations, to perform an appropriate statistical test, like a t-test, to determine if there is a statistically significant difference between the mean commute times of the two groups.
Concluding if this difference is significant would involve looking at a predefined significance level (like 5% or 10%) and comparing the p-value from the test to this level. If the p-value is less than the significance level, we reject the null hypothesis and can claim there is a significant difference in the mean travel times between men and women.
