<u>2. What is P(M), the probability that a student plans to major in mathematics?</u>
- P(M) = number of students who plan to major in mathematics / number of students
Answer:
After 5 months they will both have $325 in their savings account
Step-by-step explanation:
200, 225, 250, 275, 300, 325
150, 185, 220, 255, 290, 325
So you can see that they both have the same amount after 5 months
Answer: ×=5
Step-by-step explanation: Add 3 to both sides. simplify. Subtract 2× from both sides of the equation and u will get ×≡5
Answer:
990, C
Step-by-step explanation:
The formula for the surface area of the bottom cushion is
A = 2wl + 2lh + 2hw (w is width, l is length, h is height)
w = 18, l = 21, h = 3
A = 2(18)(21) + 2(21)(3) + 2(3)(18)
A = 2(378) + 2(63) + 2(54)
A = 756 + 126 + 108
A = 990 (C)
3 3/8 + 6 2/5 + 3 7/8 + 4 5/8 = 731/40 and simplify that and u get 18 11/40.
