Answer:
Total number of ways are 336.
Step-by-step explanation:
It is required to find the number of ways in which we can award a 1st, 2nd and 3rd place prize among eight contestants. It means we need to find the number of permutations. We need to find .
Here, r = 3
So,
So, there are 336 ways.
In the problem 56x31, what are the partial products? To acquire the possible partial products we can just multiply the two numbers to produce the possible numbers at hand. <span><span>
1. </span>56 x 31 = 1736</span><span><span>
2. </span>31 x 56 = 1736</span><span> </span>
<span>Same outcome which is explained by the comutative property of multiplication.</span>
Percent change = (new - old)/old * 100
(6/7 - 3/7)/(3/7) * 100
3/7 * 7/3 * 100
1 * 100
100%
First, turn 70% into a decimal by dividing 70 by 100.
70% ⇒ 0.70
Multiply 120 by 0.70.
120 × 0.70 = 84
Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are <em>not</em> involved in extracurricular activities.
120 - 84 = 36
<h2>Answer:</h2>
<u>36 seventh grade students are not involved in extracurricular activities.</u>
