Answer:
I think it's positive
Step-by-step explanation:
Since the dvd is $7.55 "Less" than the CD you should add.
$14.95+$7.55=$22.5
That's your answer to how much the dvd is.
If you have to subtract it
Write it like this $22.5-$7.55=$14.95
Answer:
Step-by-step explanation:
The null and the alternative hypothesis can be computed as:
The t- student test statistics can be computed as:
t = -2.017
degree of freedom = (n₁-1)+(n₂-1)
= (100-1) + (130-1)
= 228
At t = -2.017 and 228 df
P-value = -0.224
Decision rule: Not to reject the null hypothesis if the p-value is greater than ∝(0.01)
Conclusion: We reject the null hypothesis since the p-value is less than ∝.
Thus, there is sufficient evidence to conclude that the mean age of entering prostitution in Canada is lower than that of the United states.
Answer: Option a.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Find the slope of the line with this formula:
Choose two points from the table and substitute the coordinates into the formula. Then, the slope is:
By definition, the line intersects the y-axis when the value of "x" is zero. So, based on the table, the y-intercept is:
Then the equation of the line is:
The line intersects the x-axis when the value of "y" is zero, then substituting y=0 into the equation of this line, and solving for "x", you get:
So, the point of intersection with the x-axis is:
Since the table shows the amount of air leaking from an inflatable as a function of time, you can conclude that meaning of the x-intercept in this scenario is: "The time it takes all the air to leave the inflatable".
