Answer:
There will be a minimum of 8,100 books with coloured illustrations.
Step-by-step explanation:
Change the percentages to fractions
90% = 9/10
Books with Illustrations: 9/10 of 10,000
Books in Colour: 9/10 of 10,000
Because both events are not mutually exclusive, they can happen at the same time. So multiply their fractions (probabilities).
9/10 * 9/10 =
9 * 9 = 81
10 * 10 = 100
The probability of having a book with coloured illustrations is 81/100.
Find this as a fraction of 10000.
10000 ÷ 100 × 81 = 8,100
Answer:
x < - 
or x > 2
Step-by-step explanation:
inequalities of the form | x | > a always have solutions of the form
x < - a or x > a, hence
5x - 4 < - 6 or 5x - 4 > 6 ( add 4 to both sides in both inequalities )
5x < - 2 or 5x > 10 ( divide both sides by 5 in both inequalities )
x < - or x > 2
The solutions can be expressed in interval notation as
x ∈ (- ∞, - ) ∪ (2, ∞ )
45/900=110/x
x=(110/45)*900=2200 students
Cristine will find 2200 students when she gets to high school.
