Answer: 9/100
Step-by-step explanation:
Probability of people own a cat:
P(cat)=30/100=0.3
Probability of people own a bird:
P(bird)=3/100=0.03
Probability of both own a cat and a bird
P(cat and bird)=(30/100) × (3/100)
=90/1000=9/100=9%
X=-4y+2
3(-4y+2)+2y=11
-12y+6+2y=11
-10y+6=11
-6=-6
-10y=5
y=-1/2
3x+2(-1/2)=11
3x-1=11
+1=+1
3x=12
x=4
Solution:(-1/2,4)
Answer:
a) Trained 730 hours
b) 30.42 days
c) 4.35 weeks
Step-by-step explanation:
Hours the dog trained:
2 * 365 = 730
In days:
730/24 ≈ 30.42
In weeks:
30.42/7 ≈ 4.35
