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"
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.

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
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.

f(t)=10t2+5t+1 . Find the value of t for which the tangent line to the graph of f(t) has slope 1.
The value of t for which the tangent line to the graph of f(t) has slope 1 is -1/5.
The given function is f(t)=10t²+5t+1.
We need to find the value of t for which the tangent line to the graph of f(t) has slope 1.
What is the tangent line to the graph?In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve.
Now, f'(t) = slope of the tangent line to the curve at the point (t, f(t)).
Given, f'(t) = 1
f(t)=10t²+5t+1
⇒f'(t)=20t+5
⇒1=20t+5
⇒20t=-4
⇒t=-4/20
⇒t=-1/5
Therefore, the value of t for which the tangent line to the graph of f(t) has slope 1 is -1/5.

Solve for x. 4−(2x+4)=5 x=32 x=−52 x=−10 x=6
please help
The solution to the equation 4−(2x+4)=5 is x = -2.5. None of the provided suggestions x = 32, x = -52, x = -10, x = 6 are correct.
Explanation:To solve for x in the equation 4−(2x+4)=5, you first simplify the expression in the parentheses, which creates the equation 4 - 2x - 4 = 5. This simplifies to -2x = 5. You then divide each side by -2 which results in x = -5/2 or x = -2.5. So the solution to this equation is not any of the provided x = 32, x = -52, x = -10, x = 6 but rather x = -2.5.

sin α = 21/29, α lies in quadrant II, and cos β = 15/17, β lies in quadrant I Find sin (α - β).
The value of sin (α - β), where sin α = 21/29 and α is in the 2nd quadrant, and cos β = 15/17 and β is in the 1st quadrant, is calculated to be 379/493.
Explanation:In trigonometry, the formula for sin (α - β) is defined as sin α cos β - cos α sin β. Given the problem, we know sin α is 21/29 and cos β is 15/17.
However, we need to determine cos α and sin β. In these cases, we use the identity sin² α + cos² α = 1, and its counterpart for β. For α being in the second quadrant, cos α would be negative. Therefore, cos α = -√(1 - (21/29)²), which simplifies to -8/29. Similarly, for β in the first quadrant (where sin β is positive), sin β = √(1 - (15/17)²), which simplifies to 8/17.
Substitute these values into the formula for sin (α - β), we have sin (α - β) = (21/29 * 15/17) - (-8/29 * 8/17) = 315/493 + 64/493 = 379/493.
