Maggie answered 20 out of 25 questions correctly on a math test. What percent of the questions did she answer correctly?

80% (B)

Step-by-step explanation:

To calculate the percentile test score, all you need to do is divide the earned points by the total points possible. In other words, you're simply finding the percentage of good answers:

1)percentage score = #correct / #total

2)As #correct + #wrong = #total, we can write the equation also as:

percentage score = (#total - #wrong) / #total

3)Then, all you need to do is convert the percentage score into a letter grade.

probability for j is 1/4

while

a is 1/6

"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.
