<u>Answer:</u>
- There is a 41.7% chance that you got a blue ball.
<u>Step-by-step explanation:</u>
<u>Total number of blue balls/Total number of balls x 100 = Chance of getting a blue ball</u>
- => 5/12 x 100
- => 5/6 x 50
- => 5/3 x 25
- => 125/3
- => 41.7
Hence, <u>there is a 41.7% chance that you got a blue ball.</u>

Answer: +42x
Step-by-step explanation:
The student only multiplied each term individually.
He should have (7x+3)² = (7x+3)(7x+3)
Which is 49x²+42x+9
Therefore the error is (42x) or the failure to apply the law of multiplication of variables in a bracket.
Answer:
7 divided by 2
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(3, - 2) and (x₂, y₂ ) = D(7, - 8)
CD = 
= 
= 
=
≈ 7.2 → D
