Answer:
well, its 10 for 4. so 8 is 20, 12 is 30, 16 is 40 20 is 50, and 24 is 1 hour, 2 tabels is half the time so 5 min... so it would take -1 hour and 5 min
Step-by-step explanation:
Answer:
b. You would conclude that the differences in the average scores can be traced to differences in the working memory of the two groups.
Step-by-step explanation:
Though the average scores of the two sets could have lead to various conditions, but retentive ability deminishes with respect to an increase in age. With respect to the age of the elderly people involved, it is expected that some of them would not be able to retain information for a long period of time. Thus, their average score is 72%.
The college students' are younger, so it is expected that they should be able to retain more information. That ability is one of the reasons why their average score is 85%.
It can be concluded from the research that the differences in the average scores is probably due to the working memory of the two groups.
Answer:
The area below the line is shaded.
Step-by-step explanation:
Using the zero-interval test [test point (0, 0)], we plug in 0 for both <em>y</em><em> </em>and <em>x</em><em> </em>to determine whether we shade <em>below the </em><em>line</em><em> </em>[the portion that DOES contain the origin] or <em>above</em><em> </em><em>the</em><em> </em><em>line</em><em> </em>[the portion that does not contain the origin]. This is where me must verify the inequality as false or true:
![\displaystyle 0 < 2[0] + 1 → 0 < 1](https://tex.z-dn.net/?f=%5Cdisplaystyle%200%20%3C%202%5B0%5D%20%2B%201%20%E2%86%92%200%20%3C%201)
This is a genuine statement, therefore we shade <em>below</em><em> </em><em>the</em><em> </em><em>line</em>.
I am joyous to assist you anytime.
Part A: D) x is positive, y is negative.
Part B: C) both x and y are negative.
Part A:
P' is found by rotating P 90° counterclockwise about the origin. This makes the coordinates (x,y) transform to (-y,x). Thus (-2,-1) maps to (1,-2).
Part B:
Q'' is found by rotating Q 90° counterclockwise about the origin, then reflecting across the x axis. This makes the coordinates (x,y) first transform to (-y,x), then makes the new y-coordinate the opposite sign. Thus (1,2) first maps to (-2,1), then to (-2,-1).
