expressing a number with products of prime number
Step 1
State the formula for the probability of an event
The required number of event= The students with 2 or more pets= 15+7+3+2+0 = 27
Total number of events=4+11+15+7+3+2+0=42
Step 2
Estimate the probability that a randomly selected student from this class has 2 or more pets.
Answer; Option C 27/42 or approximately 0.64
Answer:
$7.5
Step-by-step explanation:
Let
Quantity of stickers=x
Price of stickers=y
5 stickers cost $3
12 stickers cost $y
x/y = x/y
5/3 = 12/y
Cross product
5y=12*3
5y=36
Divide both sides by 5
5y/5 = 36/5
y=7.5
12 stickers= $7.5
Therefore, the price of 12 stickers= $7.5
