Step-by-step explanation:
The bag has:
- 2 yellow marbles
- 3 red marbles
- 5 blue marbles

The probability of picking a yellow marble is 2/10=1/5.
So, the answer is (1/5)² = 1/25

Answer: 3 people ordered soup.
Step-by-step explanation:
Let x be the number of people ordered salad and y be the number of people ordered soup.
As per given,
x=2y (i)
7.50x+6.25y= 63.75 (ii)
Substitute value of c =2y in (ii) , we get
7.50(2y)+6.25y= 63.75
⇒ 15y+6.25y = 63.75
⇒21.25y = 63.75
⇒ y= 3 [divide both sides by 21.25]
Then, x= 2(3) =6
So 6 people ordered salad and 3 people ordered soup.
Answer:
-1/3
Step-by-step explanation:
slope = m = rise/run = (difference in y)/(difference in x)
m = (4 - 2/(-3 - 3)
m = 2/(-6)
m = -1/3
