Hey there!
Point D is located at point (5, -2)
In coordinates, the first number represents the x-coordinate, and the second number represents the y-coordinate. (TIP: YOU MUST START AT THE ORIGIN, OR (0, 0). In the x-coordinate, you go left/right that number of spaces, left for negative and right for positive. For the y-coordinate, you go up/down that number of spaces, down for negative and up for positive. This means that the point (5, -2) is 5 units right and 2 units down, which lands on point D.
Hope it helps and have an amazing day!
Easy 288/30=9.6 and tell me if you need the step-by-step
Answer:
Step-by-step explanation:
Since we have an x under that radical, we have to get it out from under there. To do that, do the opposite of the square root, which is to square. But because this is an equation, you have to do the same thing to both sides. Doing this gives you
Get everything on one side and set the quadratic equal to 0 and solve for x:
Factor this into 2 factors of (x - 3)(x - 3) = 0. As you can see they are both the same, so x - 3 = 0 and x = 3. That's your answer. x = 3.
25x - 6 = 24 + 5x
First we collect terms
20x = 30
Now we divide by 20
x = 30/20
x = 1.5

2=(x-2.7)/.5
(2)(.5) = x-2.7
1=x-2.7
x=3.7
-2.5=(x-2.7)/.5
(-2.5)(.5) = x-2.7
-1.25 =x-2.7
x=2.7-1.25 = 1.45
b)
95% of the students' score lie within 2 standard deviation of the mean. Therefore, the top 2.5% corresponds to a z value of 2.
The limits are (2, infinity) --- top 2.5 %</span>
