Answer:
False (I assume it's a true/false question)
Step-by-step explanation:
Standard deviation measures how spread out the data is. If you add 8 to all the data values, the distribution of data moves to the right (on a graph) 8 units. The shifted data are no more and no less spread out than before. The standard deviation does not change.
1. 0 - 34 + 13 - 5 = -26.....26 ft below the surface
2. y = 15x + 50
220 = 15x + 50
220 - 50 = 15x
170 = 15x
170/15 = x
11 1/3 = x......he worked 11 1/3 hrs.......not sure about this...because it does not specify how many visits he made...but if this was just for 1 visit, then he worked 11 1/3 hrs
Answer:
54.
Step-by-step explanation:
(self-explanatory.)
Remember that the volume of a cylinder is
so we have that
so the radius is 9.6 milimeters
Answer:
slope is -1
Step-by-step explanation:
y1-y2/ x1-x2
= -3 - 7 / 8 - (-2)
= -10/ 10
= -1
