Answer:
1,324 responses
Step-by-step explanation:
If the number of "Yes" and "No" answers are stated and then it was given that the remaining answers were "Not sure", it can be assumed that no answer was "Don't Care". Therefore, the sample size is the sum of the number of "Yes", "No", and "Not sure" answers:
The sample size for this poll is 1,324 responses.

Answer:
As the lengths of the two sides is equal. i.e. WY = WX . Therefore, the triangle WXY is an isosceles triangle.
Step-by-step explanation:
Considering the triangle with the vertices
The distance between the W(-10, 4) and Y(-5, 11) is the length of the side WY.
So,
So, the length of the side WY .
Similarly,
The distance between the W(-10, 4) and X(-3, -1) is the length of the side WX.
So, the length of the side WX .
As the lengths of the two sides is equal. i.e. WY = WX . Therefore, the triangle WXY is an isosceles triangle.
Answer:
(1) Subtracting the 7% from both is incorrect. This is easy to see by drawing a large circle to represents all bio majors, a mid-size circle (inside the big-circle) that takes up 52% of the area of the big circle to represent those bio majors who take stat, and a small-circle (inside the big-circle) that overlaps the mid-size circle to represent those bio majors who take computer science. The area of overlap of the mid-size circle and the small-circle is 7% of the total area of the large circle.
Now add the none overlap areas of the mid-size and small circle, and to that add the overlap:
You get (in percent) 52 + 23 - 7 = 68 %. That's .68.
(2) Consider only the students who have taken statistics. That's the mid-size circle in (1). And for these students what fraction have taken computer science? The fraction is 7/52 (and not 7% since we have limited the question to a specific group of students).

Step-by-step explanation:
12 muffins = 1 cup
x = 1 1/4 cups
x = 5/4 cups
cross multiply:
12*5 / 4 = x * 1
3 * 5 = x
x = 15
Answer = 15 Muffins
Other way:
1 1/4 cups = how many muffins
you already know 1 cup = 12 muffins
remaining 1/4 cups = how many muffins?
1/4 of 12 = 3
So 12 + 3 = 15 muffins
