Answer:
8 / 15
Step-by-step explanation:
Sample space = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}
Required outcome :
Even numbers = (2, 4, 6, 8, 10, 12, 14) or 13
Total required outcomes = 8
Probability = required outcome / Total possible outcomes
P(even number or 13) = 8 / 15
(y - 2)²
9y² - 12y + 4 ← is a perfect square of the form
(ax - b)² = a²x² - 2abx + b²
Compare like terms with 9y² - 12y + 4, thus
a² = 9 ⇒ a = 3
b² = 4 ⇒ b = 2 and
- 2ab = - 2 × 3 × 2 = - 12
Thus
9y² - 12y + 4 = (3y - 2)²
x<-9
x−1<−10
Add 1 to both sides.
x<−10+1
Add −10 and 1 to get −9.
x<−9

Hoped this helped :)
926% and I'm pretty sure the other one is 0.7
Step-by-step explanation: For a you have to remove the decimal. for b you have to remove the %
I guess I can!!
