On a coordinate plane, which point lies on the x-axis? a) (−4, 4) b) (−4, 0) c) (0, −4) d) (4, −4)

B

Step-by-step explanation:

Points on the x-axis always have the same pattern to their coordinates. x is a number and y = 0. So for example (2,0) is on the x axis. This means the solution is B (-4,0).

Solution C is not correct because it sits on the y-axis.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

answer4 to the second power is 16

and 4 to the third power is 64,
