For this specific problem, this would be the solution:   <span><span>= 0.7(133) + 0.8(133) - 2(0.4[133]) </span><span>
<span>= 93 + 106 - 2(53) </span>
<span>= 199 - 106 </span>
<span>= 93 </span></span></span>

This means 93 students passed in both the subjects. I am hoping that this answer has satisfied your query about and it will be able to help you.

if trapezoid ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A’lie
maria [59]

Answer:

<em>Answer: (second option) (-4,1)</em>

Step-by-step explanation:

<u>Transformations of Points and Shapes</u>

The image shows a trapezoid ABCD where point A has coordinates (-4,1).

The following transformations are performed:

Reflection over the y-axis: If a point (x,y) is reflected over the y-axis, it becomes (-x,y). Thus point A becomes A'=(4,1)

Reflection over the x-axis: If a point (x,y) is reflected over the x-axis, it becomes (x,-y). Thus point A' becomes A''=(4,-1)

Rotation 180°: If a point (x,y) is rotated 180°, it becomes (-x,-y). Thus point A'' becomes A'''=(-4,1)

Answer: (second option) (-4,1)
