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)

If the probability of an event occurring is 0.4,what is the probability of the even Not occurring
insens350 [35]
Answer: 0.6

-------------------------------------------------------------------------------
To get this answer, subtract the given value (0.4) from 1 to get
1-0.4 = 0.6

The reason why this works is because the event either happens or it doesn't happen. There are no other options. So if
A = event happens
B = event doesn't happen
then P(A)+P(B) = 1 which leads to P(B) = 1-P(A)

Please help me on this math problem. I does not make any sense&gt;
Semmy [17]

Answer: She did not create it correctly because we have two science students and six music students instead of three science students and five music students. I believe pie charts work well because they give a quick overview of the students.
