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).

Solution:
Remember to follow PEMDAS.
= -2 - (-8) + 4 - (-7) / 3.5
= -2 - (-8) + 4 - (-2)
= 6 + 4 - (-2)
= 10 - (-2)
= 12

Answer:
12

Hope This Helped! Good Luck!
Y = 0
x = ?
y= x^2 -6x +9
0 = x^2 - 6x +9
(x -3)
(x -3)
(x-3)(x-3)
x = 3
y = 3^2 - 6(3) + 9
y = 9 - 18 + 9
y = 18
Answer
x= 3, y = 18
hope this helps :D

Answer:
(A-1)/rt=P
Step-by-step explanation:
A= 1 + Prt Subtract 1 from both sides
-1 -1
A - 1 = Prt Divide rt on both sides
(A-1)/rt = P
