Answer:
Whiskers is two-third times as heavy as piglio is.
Step-by-step explanation:
Given:
Weight of whiskers is, 
Weight of piglio is, 
In order to compare their weights, we have to divide both the weights and then express one weight in terms of the other.
Therefore, dividing whiskers weight by piglio's weight, we get:
Now, when we divide two fractions, we replace the division sign by multiplication and reverse the second fraction. This gives,
Now, expressing 'W' in terms of 'P', we multiply both sides by 'P. This gives,
Therefore, the weight of whiskers is two-third times as heavy as piglio is.
He would have to sell at least 19 vacuums.
Answer:
<u>The correct answer is 5/24 or 0.21</u>
Step-by-step explanation:
1. Let's review all the information given to answer the question correctly:
Science class in seventh grade = 4 girls and 4 boys
Science class in eighth grade = 5 girls and 7 boys
2. What is the probability that both students selected for the competition are girls, a seventh grader and an eighth grader?
These are independent events, therefore:
Probability of two independent events = Probability of A * Probability of B
Probability of both students selected for the competition are girls = 4/8 * 5/12
Probability of both students selected for the competition are girls = 20/96 = 5/24
<u>The correct answer is 5/24 or 0.21</u>
