Answer: 5/6
Explanation: Since we're finding the probability of 1 or 2 people living on the first floor, we need to consider all of the times that either no one lived on the first floor or all three people lived on the first floor and subtract that from 12, which is our sample space.

There are only two cases where three people lived on the first floor. Hence, we have 10/12 times 1 or 2 people are living on the first floor.

This reduces down to a 5 in 6 chance.

L is the midpoint of line segment KM. If KL = 2x - 3 and LM = x + 7. find the value of x.
tatyana61 [14]

Answer:

x = 10

Step-by-step explanation:

Since L is the midpoint

KL = LM

2x-3 = x+7

Subtract x from each side

2x-3-x = x+7-x

x-3 = 7

Add 3 to each side

x-3+3 = 7+3

x = 10

Based on the graphs of f (x) and g(x), what must the domain of (f ⋅ g)(x) be?
bekas [8.4K]

Using the concept of domain, the domain of (f.g)(x) is given by:

{x ∈ ℝ | x ≠ 3}

---------------------

  • The domain of a function is given by all possible input values, that is, <u>on a graph, all values that the x-axis assumes.</u>
  • In the graph, <u>function f assumes all real values.</u>
  • Function g is not defined for x = 3, thus, it's domain is all real values except 3.
  • Thus, the multiplication, as fg(x) = f(x) \times g(x), will also not be defined at x = 3, and the domain of the multiplication is:

{x ∈ ℝ | x ≠ 3}

Question Progress<br> Homework Progress<br> 4/<br> Work out the size of angle x.<br> 105<br> 140
agasfer [191]

Answer:

Step-by-step explanation:

Sum of angles of a triangle = 180

x + (180 - 105) + (180 -140) = 180

x + 75 + 40 = 180

x = 180 -75 - 40

x = 65
