A teacher asks students to determine the accuracy of this statement. A reflection over the x-axis and then over the y-axis results in the same transformation as a 180° rotation about the
origin of the original figure.
Kwame's explanation of the accuracy of the statement is shown below.
Step 1: Choose the vertices of a pre-image: (1, 2), (1, 4), (2, 3).
Step 2: Reflect the pre-image over the x-axis: (1, -2), (1, -4), (2, -3).
Step 3: Reflect the figure from step 2 over the y-axis: (-1,2), (-1,4), (-2, 3).
Step 4: Rotate the pre-image 1800 (-1, -2).(-1,-4), (-2, -3).
Step 5: Compare the reflected figure to the rotated figure. The vertices are not located in the same place, therefore the
statement made by the teacher is inaccurate,
Which best explains Kwame's solution?
Kwame's explanation and solution are incorrect. He reflected the image over the y-axis in step 2 and the x-axis in
step 3, instead of the reverse.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
