First calculate how many cookies makes in one hour and then I calculate the number of cookies he makes in nine hours
By doing a reflection over the x-axis and a translation two units to the left (Choice 1), we see that triangle RST is congruent to triangle ACB.
Let's test this.
R(1,1)
S(1,5)
T(4,1)
A reflection across the x-axis follows the rule of (x,-y). Doing this, we get the new points:
R(1,-1)
S(1,-5)
T(4,-1)
Then we move the triangle two units to the right. This follows the rule (x-2,y). Our new points are:
R(-1,-1)
S(-1,-5)
T(2,-1)
We can see that points R, S, and T correspond to all the points on ACB, so this answer choice is correct.

6.68% of the students scored at least 19 points on this test while the 85 percentile has a test score of 24.08 points
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
P(x > 19) = P(z > 1.5) = 1 - P(z < 1.5) = 1 - 0.9332 = 0.0668
6.68% of the students scored at least 19 points on this test
b) 85 percentile corresponds to a z score of 1.04
The 85 percentile has a test score of 24.08
