Answer:
(5x +4y)^2
Step-by-step explanation:
The first and last terms are both perfect squares, and the middle term is twice the product of their roots. That means the trinomial is the perfect square trinomial ...
25x^2 +40xy +16y^2 = (5x +4y)^2
_____
It matches the pattern ...
a^2 +2ab +b^2 = (a +b)^2
The answer is t=4 hope it right
Answer:
The most appropriate inference procedure for the investigation is;
a. A linear regression t-interval for the slope
Step-by-step explanation:
Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'
The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant
Therefore, a linear regression t-interval for the slope is most appropriate.
Hey! So, you know she bought two clipboards. You're going to want to add 2.23 and 2.23 together, which is 4.46. Sheila only bought one notebook, so you simply add 4.46 and 0.58 together, which is 5.05. But, wait! She paid with a 10 dollar bill. Now, we have to take 5.05 out of 10.00, which is 4.95. Now, our answer is going to be $4.95 in change. I hope I helped! :)
