IRISSAK [1]3 years ago
8 0

Answer:

The complement of an event A is the collection of all outcomes in the sample space that are not in A.

Step-by-step explanation:

We have to fill the sentence in the given question:

Complement of an event:

  • Let A be an event, then complement of an event is defined as the the event with outcome not in A.
  • It is represented as A'
  • We can write P(A') = 1- P(A)
  • P(A) + P(A') = 1

Thus, we can fill the bank as

The complement of an event A is the collection of all outcomes in the sample space that are not in A.

(25 PNTS!!) The area of a rectangle is 63 square meters. If the length of the rectangle is 2 m longer than its width, find the d
chubhunter [2.5K]

Answer:

w = 7m

l =9 m

Step-by-step explanation:

Let w = width

l = w+2

A = l*w

63 = (w+2) * w

63 = w^2 +2w

Subtract 63 from each side

0 = w^2 +2w - 63

Factor

What 2 numbers multiply to -63 and add to 2

9*-7 = -63

9-7 = 2

0 = (w +9) ( w-7)

Using the zero product property

w+9 =0     w-7 =0

w = -9        w = 7

Since we cannot have a negative length

w=7

l =w+2 =7+2 = 9

PT= 5x+3 and TQ= 48 midpoint of PQ is
prisoha [69]

Remark

This really can't be done unless you know that T is the midpoint. I'm pretty sure it is intended to be.

Solve

5x + 3 = 48 Subtract 3

5x = 48 - 3

5x = 45 Divide by 5

x = 45/5

x = 9
