Answer:
(-3 , -3)
Step-by-step explanation:
A: (-1,2), B: (1,2), and C: (-1,-3) .... D: (x,y)
slope of AB = (2-2)/(1 - -1) = 0 .... parallel to x axis
x coordinate of A is 2 units left to B (-1 vs 1)
y coordinate of C is 2 units left to B so D must be 2 units left to C: -1 -2 = <u>-3</u>
DC // AB , y coordinate of D = C =<u> -3</u>
D: (-3 , -3)
Answer:
It will take 8 hours to drive 400 miles
Step-by-step explanation:
The millers drive 50 miles an hour. So we can write the proportion 1/50 = x/400. Then we solve for x and get 8 hours.
The mean price goes between $ 41.16 and $ 42.84, so a value of $ 48 is unusually high.
Since the average price of an item is $ 42 with a standard deviation of $ 3, to find a 98% confidence interval about the mean, and determine if a value of X = 48 is unusually high or if it is normal, the following calculations should be done:
- (((42 - 3) + (42 + 3)) / 2) x 0.98 = X
- ((39 + 45) / 2) x 0.98 = X
- 42 x 0.98 = X
- 41.16 = X
- (((42 - 3) + (42 + 3)) / 2) x 1.02 = X
- ((39 + 45) / 2) x 1.02 = X
- 42 x 1.02 = X
- 42.84 = X
Therefore, as the mean price goes between $ 41.16 and $ 42.84, a value of $ 48 is unusually high.

Step-by-step explanation:

To find the side lengths, you have to factor 4x^2 + 28x + 49. This equation factored is (2x+7)(2x+7), so each side length is (2x+7) feet.
