The graph below illustrates the time students took to complete a test when all students were allowed to finish. The distribution has mean 65 minutes and standard deviation 10 minutes. Using the Empirical Rule, if the instructor sets a time limit of 75 minutes, at least % of students should be able to finish because this is one standard deviation above the mean.

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

the answer is 62.8 cubic units

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
