Answer:
<h2>A good estimate would be</h2> and
.
Step-by-step explanation:
To solve this problem, you can find the probability of each case, red chips and yellow chips, which are gonna be simple probabilities, that is, the quotient between the number of events and the number of possible outcomes.
We know that the student reaches nine red chips out of 20, the probability is
Also, the students reaches eleven yellow chips out of 20, so
Thefeore, a good estimate would be and

Answer:
Step-by-step explanation:
Given
<em>Translation: 3 units left and 1 unit right</em>
Required
Determine the new coordinates of B
Write out the coordinates of B
When a function is shifted to the left, we have to subtract the unit from the x value of the function;
<em>Shifting by 3 units left, the new x becomes </em>
<em /><em />
<em /><em />
<em />
When a function is shifted upward, we have to add the unit to the y value of the function;
<em>Shifting by 1 unit up, the new y becomes </em>
Hence, the new coordinates of B is
