Because there were 15 yellow balls and 60 in total:
15/60
We can simplify:
1/4
Multiply both sides by 25:
25/100
The relative frequency is 25%
The instructor wants the profit to be positive, so
f(n) > 0
70n -400 > 0
n - 400/70 > 0
n > 5 5/7
The instructor must enroll at least 6 students to make a profit.
<u><em>Answers:</em></u>
Rotating
Reflecting
Translating
<u><em>Explanation:</em></u>
Congruence transformation is a transformation that does not change neither the side lengths nor the measures of the angles.
This means that the formed image is an exact copy of the original figure
<u>Now, let's check the options:</u>
<u>1- Shrinking:</u> This means that we are decreasing the side lengths.
This option is incorrect
<u>2- Rotating:</u> This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct
<u>3- Reflecting:</u> This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct
<u>4- Stretching:</u> This means that we are increasing the side lengths.
This option is incorrect
<u>5- Translating:</u> This means that we are just changing the position of the figure without altering any measurements.
This option is correct
