Answer:
Jesse - 150 miles per hour.
Step-by-step explanation:
On the graph, it shows that the rise is 140 and the run is 1. 140/1 is 140, making the slope for Khalid is 140. The equation (y = 150x) shows that the slope is 150 (y = mx). Since 150 is greater than (>) 140, Jesse's train is more faster than Khalid since she is moving at 150mph rather than 140mph.
Answer:
D
Step-by-step explanation:
It is opposite of one the angles on the same line as n so it is the same value
Answer:
C.
Step-by-step explanation: im pretty sure because if you look at Ed its 5 and then if you add the same sides twice its 10 hopefully im right
The critical value is z=1.88.
We find this by first converting the percent confidence we want to a decimal: 94% = 94/100 = 0.94
We subtract that from 1 to find the alpha level:
1-0.94 = 0.06
Divide this by 2 (to find the area in each tail):
0.06/2 = 0.03
Subtract this from 1 again (because we want the area in the middle, not in each tail):
1 - 0.03 = 0.97
Using a z-table (http://www.z-table.com) we see that the closest to this in the table is at z = 1.88.
Answer:
(x - 7)² + (y + 2)² = (2√13)²
Step-by-step explanation:
We already know that the center is at (7, -2), but must find the radius. The radius is the distance between the points (7, -2) and (1, -6):
r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.
Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²
