3/5 x 30 = 18 pages.
18 pages are filled.
30 - 18 = 12
12 pages are not filled.
1/4 x 12 = 3 pages

Answer:
D
Step-by-step explanation:
a² - b² ← is a difference of squares and is factored in general as
(a + b)(a - b)
42² - 38² ← is a difference of squares and factors as
42² - 38² = (42 + 38)(42 - 38) = 80(4) = 320 → D
Answer:
1,75
Step-by-step explanation:
The Mosteller formula is
[/tex]
We know that height is 68 inches and weight 141 pounds
We must remember that 1 inches = 2.54 cm and 1 pound 0.453 kg
This means 68 inches = 172.72 cm and 141 pounds = 63.95
We substitute on the formula
Mutually exclusive means that the intersection of the events is empty: P(S and T) = 0.
P(S or T) = P(S) + P(T) = 29% + 49% = 78%
If events S, T are not mutually exclusive, then P(S or T) = P(S) + P(T) - P(S and T)

![-5.4 + 5.4 = -10.8](https://tex.z-dn.net/?f=-5.4%20%2B%205.4%20%3D%20-10.8)
________
<em>now, note that if this was actually subtracting, logically, the answer would be H = 0</em>
<em>however, this is an addition problem, meaning to add a negative and a positive integer to get a negative integer.</em>
